It is natural for a company that makes highly sensitive medical devices to turn to a trusted vendor to make its components. But if those components are made of plastic and that vendor is a metal machinist, that can be a huge mistake.

A company that specializes in only machined plastic parts not only brings expertise in dealing with plastics to the table, but can help avoid problems that might arise from contamination or simply not understanding the subtle differences between working with plastic, as opposed to metal parts.

Take the case of a medical analytics company that turned to a metal machinist to make a plastic component. The part had precisely made holes that needed to contain a small ball to measure gas levels. If working properly, the ball would float in the instrument. Unfortunately, even after passing initial inspections, these parts sometimes failed after two to three weeks in the field. The ball would no longer rise. The manufacturer thought it was a problem with static—a reasonable assumption, but one that proved wrong. The real problem became apparent after putting the piece under a microscope. There were tiny cracks inside the holes, not visible to the naked eye. The cracks were due to crazing, a degradation caused by cutting oils. That is not an uncommon problem when metal machining equipment is used to create plastic parts.

Metal parts, unlike plastic ones, typically require the use of oil-based cutting fluids. And no matter how conscientious the metal machinist is, it is nearly impossible to clean every bit of oil from a machine before using it to make a plastic part. Because of this, equipment used to manufacture metal parts, even if used for metal only, can occasionally contaminate plastic parts with those oil-based cutting fluids. Many plastics are highly sensitive to petroleum-based cutting fluids and will degrade if they come into contact with them. Also, many plastics are hydroscopic and will absorb the cutting oils. The result is a part that may pass initial inspections, but will degrade over time and fail in the field.

It is not just cleaning oils off a machine that is difficult for a metal machinist, but also clearing every tiny metal fragment that may remain on a machine used to make metal parts. If the plastic material being machined is soft, residual metal fragments can become embedded in the plastic machined parts. Again, the metal fragment may not cause a problem initially, but over time it can cause the plastic to degrade and stop performing properly.

Problems can also arise in something as simple as how a metal machinist holds a plastic part. With plastic machined parts, the plastic is usually held with vices. Machinists who don’t specialize in plastic have a tendency to hold the plastic the same way they do metal—but this can be too tight for a plastic. As a consequence, when a drill goes into the plastic, the material flexes a bit, which can put stresses on the part that might not surface until later. A plastics machining company would know that, and be able to prevent that from happening. It is a subtle difference in manufacturing, but one that can turn into a huge problem down the road.

Of course, a plastics expert should be more knowledgeable than a metal machinist about the variety of plastics materials available and what uses they’re best suited for. This level of knowledge is especially important in fields like medical device technology, where manufacturers often use plastics that are less common than those used for other purposes. A plastics expert can help designers and manufacturers sort through materials according to factors such as sensitivity to humidity, abrasion resistance and thermo-sensitivity.

A company that specializes in only machined plastic parts not only brings expertise in dealing with plastics to the table, but can help avoid problems that might arise from contamination or simply not understanding the subtle differences between working with plastic, as opposed to metal parts.
A company that specializes in only machined plastic parts not only brings expertise in dealing with plastics to the table, but can help avoid problems that might arise from contamination or simply not understanding the subtle differences between working with plastic, as opposed to metal parts.

Sourcing is another important consideration. A metal machinist will most likely get their plastics from a distributor whose materials may come from a variety of sources. They may be able to provide certification, for example, that all the materials they are using are nylon rods, but they may not know the source of those rods. A plastics specialist, on the other hand, should be able to tell you not only what mill the material came from, but also the lot number. If there is ever a problem, they can easily trace the material back to its original source. There is a level of accountability you may not get from a metal machinist.

Of course, not all plastic machining companies are alike. The best for your job is one that is familiar with each machining process you need for your medical device application, as well as with the specific plastic material you will be using. The company should have access to up-to-date information and be willing to share it through property charts or plastic material handbooks.  They also should be ISO Certified, use documented SPC (statistical process control) procedures and own the proper inspection equipment such as CMM (coordinate measuring machine) or video inspection systems. These certifications and systems will help ensure that you receive the highest quality medical device for the lowest cost, with the fewest possible errors the first time around.

The final consideration in this is cost. Surprisingly, using a plastics expert may actually save money.  Plastics machining companies deal with plastic parts all day long. Their expertise means they can often perform the job more efficiently than the typical metal machinist. But most important, the lower risk of contamination when dealing with a plastic machinist means that medical device parts not only have a higher chance of passing inspection, but a much lower chance of failing down the road. That is important in any industry, but even more so when someone’s health is on the line.

Why Using A Plastics Machining Specialist For Instrumentation Equipment Is The Best Choice

January 29, 2016 By: Alex Curtiss, Engineered Plastic Products Corporation

 Alex Curtiss

Initial Gander

At first glance, it’s hard to see why it’s best to choose a plastics specialist to make a machined plastic part in your instrumentation product, rather than just having a metal machining company, maybe one you know and trust, do the work. A metal machining company may be able to make your plastic part. The part may look fine to the naked eye and it may also seem to work well when it’s put into a product and tested out. At first, it may even perform as it should—until something goes wrong and everyone is left scratching their heads looking for answers.

Here’s What Can Go Wrong

That’s exactly what happened to one company in Ohio who manufactures precision scientific instrumentation. A new $2 million dollar machine that they manufactured for one of their top customers was delivered and installed but soon developed an electrical problem and no one knew why. Finally, they took the whole machine apart and examined it piece by piece. Finally, in one of the plastic parts, they noticed a tiny sliver of metal embedded in the plastic.

That tiny spec was the culprit creating an electrical short circuit and that was the reason the machine had stopped working. The plastic part was machined by the company’s vendor that produces their metal components. That is one problem that can happen when a metal machining company produces plastic parts rather than an experienced plastics only specialist.

Why That Happened

This example is not a fluke. It is very difficult to adequately clean a machine that has been working on metals parts. The process can lead to contamination.

If the plastic material is soft, residual metal fragments can become embedded in the plastic machined parts. Depending on what the part is used for, the metal fragment may not cause a problem initially, but, over time, it can cause the plastic to degrade and eventually stop performing properly.

What Else Can Go Wrong

There’s another contamination risk with metal machining companies. Metal parts, unlike plastic ones, typically require the use of oil-based cutting fluids. Because of this, equipment used to manufacture metal parts, even if used for metal only occasionally, can contaminate plastic parts with those oil-based cutting fluids.

Many plastics are highly sensitive to petroleum-based cutting fluids and will degrade if they come into contact with them. Also, many plastics are hydroscopic and will absorb the cutting oils. Additionally, if these parts are being manufactured for FDA-approved uses or medical applications, they will not meet their standards.

Who Is Plastic-Materials Knowledgeable?

Generally there is not an abundance of knowledge about what plastic to use for different component applications. To say plastic is like saying vehicle. There are many types of vehicles from dump trucks to Ferraris. Both are vehicles but the quality and use is not the same. The same applies to plastic.

plastic partsPlastics specialists are knowledgeable of the variety of plastics and which are the best to use for a given application.

Metal shops are experts in metal and cannot be expected to have knowledge of the differences between the many types of plastics. Metal machining companies rarely have any in-depth knowledge of the performance characteristics of different plastics. On the other hand, a good plastic machining specialist know what plastics are best for each function and can produce the plastic part needed without risk of failure.

Ensure The Plastics Vendor Is The Correct One For The Project

Even if you do choose a plastics expert rather than a metal machining company, there are still some points to consider.

First, experience matters. Make sure the supplier you choose is familiar with each machining process you need for your application, as well as with the specific plastic material you will be using. Ask them to share information such as property charts or plastic material handbooks. Specialists in plastic machining should have a wealth of up-to-date information.

A company that specializes in only machined plastic parts not only brings expertise in dealing with plastics to the table, but can help avoid problems that might arise from contamination or simply not understanding the subtle differences between working with plastic, as opposed to metal parts.Machining metal versus plastic.

Second, check for certification. The plastic machining vendor who makes the fewest errors the first time around should give you the highest quality at the lowest cost. Plastic machining vendors can keep errors to a minimum if they are highly process driven The best ones are ISO Certified, use documented statistical process control (SPC) procedures, and own the proper inspection equipment such as coordinate measuring machine (CMM) or video inspection systems.

Remember, experience, more than anything else, will ensure a supplier can manufacture the most cost-effective part with the best quality.

plastic parts

Many designers don’t realize there are  plastics machining specialists. That’s why they often turn to a metal machinist to make their plastic parts. But doing so can cause the best designs to go awry.

Many designers see no difference between a metal machinist and a plastic machinist making a plastic part. The truth is, both are capable and both can probably make the part to a designer’s specifications. Both parts may work the way they’re supposed to, at least at first. But the potential for something to go wrong when the part is made by a metal machinist can cost a company time and money. The problem can arise from anything from contamination to a simple lack of expertise of how metal and plastic differ.

Take, for example, an Ohio company that manufactures precision scientific instrumentation.

One of their top customers took delivery of a new $2 million machine they manufactured. At first, it ran fine, but it soon developed an electrical problem. The company ended up taking the entire machine apart and examining it bit by bit before they finally figured out the cause of the short circuit—a tiny sliver of metal embedded in the plastic. This is the kind of contamination that can occur when plastic parts are manufactured by a metal machining company rather than a plastics-only specialist.

Even if you’re not producing $2 million machines, mistakes like this can still produce million dollar headaches. That’s because it’s difficult to clean machines used to make metal parts. A machine may look clean to the naked eye, but if there is as much as just one tiny metal fragment on a machine, it can become embedded in a soft plastic machined part. While the part may seem fine at first, over time, that metal fragment can cause the part to degrade and stop working properly.

A company that specializes in only machined plastic parts not only brings expertise in dealing with plastics to the table, but can help avoid problems that might arise from contamination or simply not understanding the subtle differences between working with plastic, as opposed to metal parts.

Another pitfall

The difference between how metal and plastic parts are made can also lead to contamination with metal machining companies. Unlike plastic parts, metal parts typically require the use of oil-based cutting fluids. What’s necessary for metal, though, can wreak havoc on plastic. Many plastics are highly sensitive to petroleum-based cutting fluids and will degrade if they come in contact with them. In addition, many plastics are hydroscopic and will absorb cutting oils. When this kind of contamination occurs with parts being manufactured for FDA-approved uses or medical applications, they will not meet their standards.

Why knowledge matters

Plastics and metal machinists also differ in experience. A plastic machining expert has knowledge about the different types of plastic and how those plastics perform that a metal expert can’t be expected to know. All plastics are not alike. Dealing with a plastics expert can help you choose the type that’s right for your job.

There are also differences in the properties of metal and plastic that necessitates differences in design. For example, a metal machinist may not be aware that there is a difference between the amount of stress a metal part can handle versus a plastic part. A valve screwed on with the right torque for metal might be too much for plastic, leading to cracks. Designs, too, might have to differ when working with plastics as opposed to metal. Those sharp corners that work fine in a metal design can cause stress that lead to cracks in a plastic part. A plastics specialist should know this and suggest slightly rounding those corners—saving you precious time caused by design errors.

Choosing the right plastics vendor

If you do decide to choose a plastics specialist, keep these points in mind:

  • Experience. Make sure the plastics machining expert you choose has experience with the type of machining process your product requires as well as the material you will be using.
  • Information. Specialists in plastic machining should have up-to-date information and be willing to share it with you. Ask to see materials such as property charts or plastic material handbooks.
  • Certification. Plastic machining vendors can keep errors to a minimum if they are highly process driven. The best ones are ISO Certified, use documented SPC (statistical process control) procedures, and own the proper inspection equipment such as CMM (coordinate measuring machine) or video inspection systems.

In the long run, working with an experienced plastics machining expert from the start could save money. It may be easier to farm out parts to that same machinist who is making metal components, but doing so could increase the risk of the parts failing within months of reaching the customer’s hands. Using a plastic machining specialist could be the difference between a machine that breaks down after a month on the job, and one that keeps humming along.

Plastic Machining: Selecting a Plastic Machining Vendor- Equipment

Ask about the type of equipment the potential plastic machining vendor uses. The well-equipped plastic machining vendor will look pretty much like a metal machining shop, but the true plastic machining specialist will have equipment that has been adjusted or re-built expressly for machining plastic material. The right equipment will machine plastic using the correct speeds, feeds and tooling, and won’t pose the threat of contamination faced when metal-machining equipment is utilized. The right equipment will also insure higher quality plastic machined parts with better finishes and less chance of chips, burrs and other imperfections.

Plastic Machining: Selecting a Plastic Machining Vendor- Purchasing Practices

Just as a metal machine shop is unlikely to have the material knowledge you need, neither are they going to be able to purchase plastics in large enough quantities to provide you with the best price.

Likewise, find out if the plastic machining vendor candidates you are considering can purchase materials directly from material manufacturer. If they rely on plastic distributors for materials, make sure their vendors are up on the latest material technology. Plastic technology is constantly changing with new materials introduced all the time.

One of your goals should be to make sure that your plastic machining firm’s materials purchasing practices are as good as yours.

Plastic Machining: Plastic Machining Expert-Benefits a Real Expert Should Provide

Is it important to have my plastic machined components manufactured by a plastic machining specialist? How do I know if my vendor is an expert?

YES-Selecting the right vendor is crucial, especially when selecting a plastic machining vendor.  Select an expert for the best results.  To be a true plastic machining expert, a vendor must provide the following necessary benefits:

1- Highest Quality
2- Competitive Cost
3- Fast, On-Time Delivery
4- Exceptional Customer Service

The highest quality can only be obtained from plastic machining experts. Don’t risk contamination, and a trial-and-error material selection process. Plastic machined components can be rendered useless due to contamination, and due to a failure to meet specifications and requirements. Additionally, the right vendor is an ISO Certified vendor. An ISO Certified plastic machining vendor will be able to guarantee predictable high-precision. Avoid the unnecessary cost and hassle of replacing faulty components by initially contacting a plastic machining expert.

Plastic machining experts will be able to provide competitive cost by having the appropriate processes, materials, and equipment in place. Specifically an ISO Certified plastic machining expert has processes streamlined in order to reduce idle time and eliminate waste, saving the manufacturer money. The production and overhead cost savings will lead to lower costs to the vendor’s customers.

A plastic machining expert provides faster delivery than a non-expert, as production times are shorter due to having the right equipment, processes, and materials. An ISO Certified vendor is able to reduce production time due to refined supply chain management, allowing for the assurance of fast, on-time delivery.

A plastic machining expert has all the knowledge essential in order to produce the highest precision plastic machined components. Exceptional customer service should go hand in hand with that knowledge and expertise. A plastic machining expert should provide assistance to a customer every step of the way, throughout both the engineering and purchasing processes.

Plastic Machining: Stay Domestic for Your Custom Plastic Machined Parts Needs

While the trend has been to outsource production, and to purchase from overseas companies as a cost cutting mechanism, is purchasing from a foreign firm the right move for a company in need of custom machined plastic components?

The simple answer to this question is…NO

If components are ordered from a foreign firm, the move can be far more costly than doing business with a domestic plastic machining specialist. At EPP Corporation, we serve and specialize in custom plastic machined parts for critical industries such as the aerospace, medical, instrumentation, fluid power, and military industries, the highest precision is required. These critical industries cannot use custom plastic components that do not meet strict specifications. By purchasing overseas, the risk of purchasing from a plastic machining company without certification, as well as not being able to have an open line of communication alone are huge risks. Errors would garner components useless, and replacement plastic machined parts would take long to be reordered and received (10-16 weeks on average), hindering the possibility of meeting deadlines, as well as no guarantee that the proper materials and processes are being utilized. The additional risk of items being damaged through their long transport to your doorstep, can be costly both to the pocket book, as well as creating vast time constraints. Companies often seek domestic firms to correct the errors of overseas vendors after having been put into a time crunch.

That being said, selecting the best domestic plastic machining company does require some due diligence. Not all plastic machining vendors are equipped to offer all parts. Others may not be able to give you the best prices
The following guidelines can help you locate a fully-qualified, cost effective plastic machining specialist:

At EPP Corp we pride ourselves in the value proposition of combining the highest quality, competitive cost, and fast, on-time delivery. EPP is also here to provide its customers assistance throughout the purchasing and engineering processes of our custom plastic components.
