Performance Plastics specializes in the precision injection molding of technically complicated parts in advanced materials, eliminating the need to machine.

High performance plastic materials offer ideal properties when it comes to durability. Resins like polytetrafluoroethylene (PTFE/Teflon®) are known for their dielectric strength, low dissipation, chemical resistance, outstanding performance at elevated temperatures, and levels of coefficient friction. However, these unique properties can make molding some fluoropolymers quite difficult. Performance Plastics has found a way to offer the benefits of these materials by injection molding alternate fluoropolymers such as FEP and PFA.

At Performance Plastics, we are experts at precision injection molding. We have developed proprietary tool design software, processes and equipment enabling us to injection mold components having complex geometries made from challenging high-performance thermoplastic materials (PFA/FEP/PEEK®/PTFE/Teflon®) and highly loaded compounds. We utilize a unique combination of extensive material knowledge, mold flow analysis, a design system and process expertise to eliminate or minimize the need for secondary operations.

Switching from machining parts to injection molding parts can be very beneficial. Not only does injection molding help lower costs, but it also allows for highly efficient production, complexity in part design, and enhanced part strength. Injection molding produces uniformity, the ability to make millions of virtually identical parts.

Injection molding isn’t for every project, but it can be cost beneficial for applications producing more than 10,000 pieces of the same part year over year. At Performance Plastics, we serve a variety of industries, from medical & life science, aerospace & defense to diversified industrial.

Ultem Polyetherimide is a material widely used in industrial applications.  It is an amorphous material with exceptional strength, flame resistance and generates very low levels of smoke. It is often used in the production of circuit boards, sterilization equipment, battery components and oil and gas equipment,

ULTEM is commonly used in industrial applications needing a durable, high-performance, cost-effective alternative to metal: strong enough to replace steel in some applications and light enough to replace aluminum in others.   It outperforms comparable thermoplastics when it comes to resisting creep and does not degrade under repeated mechanical stress. It also holds up well when brought into contact with various fuels, coolants, and lubricants

ULTEM has one of the highest dielectric strengths of any thermoplastic material. It works very efficiently as an electrical insulator. ULTEM also has one of the lowest rates of thermal conductivity, allowing parts machined from ULTEM to act as thermal insulators. ULTEM offers excellent long-term heat resistance with its mechanical and physical properties remaining stable at elevated temperatures.  Unlike most other amorphous plastics, ULTEM resins retain strength and resist strength cracking when exposed to environmental stresses.

Ultem is now widely used in:

  • Automotive
  • Semiconductor
  • Telecom Components
  • Molded Interconnect Devices
  • HVAC/Fluid Handling Devices
  • Oil & Gas Applications

Mating parts providing a fluid or gas seal are critical components in most mechanical systems. We commonly think of them in valves and connector assemblies, but they are also found in pressure vessels, compressors, pumps, motors, engines, transmissions, and almost all mechanical power trains. Seals, especially those that mate to moving parts, have a demanding set of quality requirements. Each application has its own specific needs, but all seals are characterized by tight dimensional tolerances and excellent surface finish.

Our customer wanted to improve the usable life and leakage profile of a valve without absorbing any increase in component cost.  The sealing surface specifications were tightened to 0.0005 inches (12.7 µ) which was key to accomplishing the performance improvements.

The previous supplier of this component was unable to meet the more stringent sealing surface dimensional tolerances “out of the mold” necessitating a finish machining operation to bring the part into tolerance.  However, machining the sealing surface removed the resin-rich surface of the part creating micro-cracks in the surface and exposing reinforcing fibers. Both of these unavoidable consequences of machining negatively impacted component performance, useful life and cost.

Solution

Performance Plastics knew eliminating the machining operation would improve strength, reduce trapped impurities, and lower manufacturing cost.  Our engineering team focused on producing a “true net shape” part directly out of the mold.   Key to accomplishing the customers goals involved leveraging our proprietary, iterative tool design process.  It required making a 3D CT scan of preliminary molded parts measuring, in this case, approximately 1 million critical part dimensions.  This analysis identified minute distortions.  Utilizing internally developed proprietary software, PPL integrated the CT scan data with CAD/CAM software to make exacting mold modifications eliminating the out of tolerance conditions.  This process contributed to producing a best in class “out-of-mold” conforming part.

The manufacturing process also had to be optimized to produce the desired performance results.  Although the material posed molding challenges, PPL decided to direct gate the part at the top to ensure symmetry of material flow throughout the cavity, critical in achieving roundness to the sealing surface.

The results of development program surprised everyone. Performance Plastics was able to achieve  “out of mold” net shape parts with a seal surface capable of meeting sealing ranges of 100 psi to 3,000 psi, with no porosity and consistently meeting dimensional tolerances of 0.0003 inches, or 7.62 µ. Eliminating the need for subsequent finish machining dropped the leakage rate for the valve by 50%, from 1.0 scfm to 0.5 scfm.

The Lithium Ion Battery industry has begun using more and more plastic parts in their manufacturing processes. Most batteries intended for light vehicle usage now have 50% more plastic materials than they did even 10 years ago.  Some batteries have entirely plastic formulations ranging from the electrolyte (polymeric electrolytes) to the casing.  This is due to the very low weight of plastics as compared to metals. Plastic incorporation in batteries increases the electrolyte efficiency if used in polymeric electrolytes.

Commercially available lithium-ion batteries also use plastics. Plastic components incorporated in batteries include separators, gaskets, and casing components. Plastics have good shock absorbing characteristics and prevent damage to the basic cell unit from minor accidental shocks. Also, plastics such as Teflon® PFA, Ultem® PEI, and PPSU have high temperature resistance, corrosion resistance, and are electrical insulators so they are excellent at preventing short-circuit and “rapid disassembly.”

There has been a major shift from metal to resins in gasket manufacturing. Gaskets can be made from Ultem®, Ryton PPS and Fluoropolymers (PFA plastic) because of high heat resistance, chemical resistance, and ability to mold thin walls (.012”). Plastic parts may also lower the cost of production of batteries and may eventually replace most metallic components of batteries.

Performance Plastics is highly skilled at designing and molding high performance materials such as FEP/PFA, Ultem®, Torlon®, PEEK, POM, and PPS.  We work with our customers to solve technically challenging problems.   We can propose materials to implement part functionality in the design stage of development. We offer manufacturing solutions such as a clean room, the ability to offer direct gating of fluoropolymers, high volume production, visual inspection and automated facilities.

Performance Plastics Improves Compressor Valve Performance With Poppets Made From VICTREX® PEEKPolymer

Manufacturers of check valves and pressure relief valves for hydraulic and pneumatic compressors are constantly looking for ways to improve the performance of their products. Valve performance, more than any other component, determines compressor efficiency.

To achieve reduction in fluid leakage, noise and cost, and extended valve life, Performance Plastics (PPL), recommends replacing the metal poppets with poppets made of VICTREX® PEEK™ polymer, a high performance thermoplastic. Experience has shown that converting to a poppet made from VICTREX PEEK polymer provides tremendous improvements in productivity.

ALLOWS WIDER OPERATING RANGE

One of the major benefits of using VICTREX PEEK polymer   is that it allows the valves to operate in high and low pressure applications. It increases the number of applications in which valves and compressors can be used.

SUPERIOR IMPACT RESISTANCE

VICTREX PEEK POLYMER —

Ideal Replacement for Metal Poppets

Metal poppets have always posed a number of challenges. They can be difficult and costly to machine and the sealing surface can be inconsistent due to difficulties in machining defect-free seat surfaces.

As a replacement for metal, VICTREX PEEK high performance polymer is an engineering solution due to its outstanding combination of properties. Substituting plastic for metal maintains strength while improving corrosion resistance, reducing weight, and allowing for greater design flexibility.

Another benefit of using VICTREX PEEK polymer is its superior impact resistance. According to Performance Plastics, one of the primary reasons why valves fail are the fissures brought on by repeated impact pressure. PPL has had applications where VICTREX PEEK polymer has passed two million impact cycles and another where it has passed 20 million impact cycles.

BETTER SEALING AND WEAR RESISTANCE

Because VICTREX PEEK polymer is compliant and can conform to the mating seat surface, it provides better sealing performance and less leakage than metal poppets. It also offers excellent wear resistance and improved wear conditions on the mating seat surface. Wear and damage to the mating seat surface is a big issue with metal poppets and re-work of pumps and valve assemblies is both costly and time consuming on the production line.

PROPERTIES OF VICTREX PEEK POLYMER

  • High Temperature Resistance — Can withstand continuous operating temperatures of up to 260°C (500°F). Also maintains short-term mechanical properties at temperatures approaching its melting point of 340°C (644°F).
  • Wear Resistance — Outstanding wear resistance over wide ranges of pressure, velocity, temperature and counterfacial
  • Mechanical Properties — Excellent strength, stiffness and long-term properties, such as creep and fatigue, retained over a wide range of temperatures and
  • Chemical Resistance — Exhibits outstanding resistance to a wide range of chemical and corrosive environments, even at elevated temperatures up to 200°C (392°F).
  • Hydrolysis Resistance — Retains high levels of mechanical properties and dimensional stability when continuously operating in water, brine or steam at elevated temperatures and
  • Dimensional Stability — Remarkably stable, resisting changes to its properties due to temperature, moisture, chemical attack or physical

METAL REPLACEMENT APPLICATIONS

Metal to plastic conversions and metal part replacement applications are areas of expertise at Performance Plastics. Because of its superb all-around properties, Performance Plastics has used VICTREX PEEK polymer successfully in many metal replacement applications including:

  • A poppet made with VICTREX PEEK polymer replaced a two-piece metal assembly, resulting in a significant cost reduction. It also improved initial product quality and reduced customer valve rework from 200 units per month to less than
  • Poppets made with VICTREX PEEK polymer provided more sensitivity than the metal poppets, resulting in more consistent pressure relief actuation performance. The plastic poppets also provided a lower noise level than the metal
