Diabetes care has seen several innovations through the years. One of the most important developments is the insulin pump, which for many patients provides an option to the traditional needle and syringe approach to insulin injections. Insulin pumps are small, computerized devices that are about the size of a small cell phone.  Insulin pumps deliver doses of insulin, the hormone that regulates blood sugar, on a pre-programmed schedule.

High performance polymers have enabled medical device manufacturers to go beyond the functionality of ordinary plastic materials to develop innovative devices for treating diabetic patients.  Resins such as FEP and PFA fluoropolymers are chemically resistant resin with outstanding properties and are currently used in numerous healthcare applications. Physical properties of resins such as high tensile strength, dimensional stability, excellent friction and wear characteristics and the ability to replicate fine features are important advantages as parts become smaller and thinner.

In developing new and advanced insulin delivery devices, resins offer unique advantages and have expanded the possibilities for innovative design and manufacturing. Medical grade fluoropolymers, such as FEP and PFA allow for the miniaturization of device components without the constraints of glass or ordinary plastic materials. With these capabilities, designers can now expand design performance and possibilities. Fine detail replication resulting from the material’s high flow and excellent dimensional stability properties position resins as an excellent material for lightweight and compact precision delivery devices.

Device components such as insulin storage require the use of a proven polymer materials. In addition to compatibility with insulin, purity and very low levels of leaching, resins provide excellent moisture barriers and extremely low water absorption, both necessary properties for optimal long-term drug container storage. These resins are also FDA approved and are compatible with all conventional sterilization methods from gamma to steam.

In future insulin delivery systems, the use of FEP and PFA resin components for various parts of the device will continue to rise. With the advantages engineering polymers offer for design innovation and performance, resins will continue to be the material of choice for delivery applications.

Choosing the best technology for your application

Plastic injection molding and 3D printing are both viable technologies. 3D printing has given engineers the power to create designs and bring them to life in a matter of hours. Injection molding, on the other hand, is the proven technology for complexity, quality, and value. It is used to produce high-volume runs of complex plastic designs quickly and reliably. They are complimentary processes.

The use of 3D printing in innovative and experimental scenarios is a viable technology for its ability to create custom plastic part designs quickly.  The medical industry has embraced the use of the quick-turn technology to create custom items such as prosthetics, dental products, orthopedics, implants and more.  3D printing is the optimal choice during the design process, when low volume and design changes are necessary in refining the design process. However, the 3D process limits your material choices, as all materials are not a fit or even available in a form suitable for 3D printing.

3D printing is best used for:

  • Quick turnaround times
  • Low volume, slower production speeds
  • Parts in the design phase with frequent changes – prototyping, lower product quality
  • Smaller part sizes

Once a design has been finalized, plastic injection molding becomes the optimal process.  Most of today’s plastic parts are manufactured using plastic injection molding – it’s best for producing large quantities quickly and reliably in high volume runs. You have greater material options with plastic injection molding, and you can control material weight, cost, flexibility with endless combinations of materials.  It helps organizations control the cost and integrity of designs with complexities and tight tolerances.

Plastic Injection molding is best used for:

  • High volume
  • Finalized part design
  • Enhanced strength and durability
  • Complex, precision, detailed parts

At Performance Plastics we have been presented with many opportunities that were previously manufactured using 3D printing, only to discover that injection molding was the more appropriate technology.  As experts in FEP, PFA, PAI (Torlon), Ryton PPS, PEEK and Ultem resins we frequently work with mission-critical applications.  We understand that 3D printing can be an essential component of the design process.  If you have a project that requires high volume (5,000+ parts per year), has high-temperature resin requirements, tight tolerance with complex geometries, plastic injection molding is your solution.

If you don’t have a lot of time, need a lot of flexibility, and need a few parts right now, 3D printing may be your choice.  But, if you need to do large, repetitive product runs with complex geometries, tight tolerances, with high quality, consider plastic injection molding.

Every project has its own needs and goals.  Complex geometries involving fine details or sharp corners often cannot be achieved by traditional plastic molding. Advanced plastic injection molding processes allow designers to combine numerous complex features into a single component, reducing the need for secondary machining or surface finishing operations.

Plastic Injection molding allows design freedom not easily matched by other traditional processes.  Performance Plastics’ augments the latest software tools including solid modeling, mold flow analysis and finite element analysis with an internally developed iterative tool design approach to deliver complex geometries and densities superior to most other operations.

Our tooling modification process results in best in class part tolerances, particularly useful in molding mission critical parts where dimensional attributes need to be extremely precise.  We use this approach to produce net shape molded parts of exceptional quality, eliminating or significantly reducing secondary matching operations resulting in material and process cost savings.

Performance Plastics, located in Cincinnati, OH has over 30 years’ experience in molding tight tolerance advanced plastics such as Fluoropolymers (FEP/PFA Torlon, Ryton plastic, Peek & Ultem) for many industries.  We have developed proprietary processes enabling injection molding of parts that are thin walled, with tight dimensional tolerances, and complex geometries.

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

PPL Races To Solution With Thermoplastic Gear

  • Market: Automotive
  • Project Requirement:  Develop a longer lived, more efficeint drop in replacement for a metal component
  • Project Requirement:  Develop a material with a low coefficient of friction not needing lubricating fluids

Overview

Metals have been the first choice of design engineers for almost three centuries. Developments in highly engineered thermoplastics materials are challenging that dominance. The aerospace and automotive industries have led the charge in this dramatic changeover, initially driven by the need to reduce weight to gain fuel efficiency. Advanced thermoplastic and thermoset systems, including fiber reinforced compositions, are now finding their way into almost every industry.

Some of the benefits arising from metal to plastic conversion are:

  • Reduced part weight and inertia;
  • Net shape (or near net shape) manufacturing, improving material efficiency;
  • Simplified manufacturing processes, with higher repeatability and less scrap;
  • Higher tensile strength with proper part design;
  • Increased part lifetime in corrosive and/or abrasive environments;
  • Greater conformability, providing improved sealing characteristics;
  • Increased lubricity;
  • Greater design flexibility.

Challenge

Race car engineers are always looking for a performance edge with their drive trains. Keeping power output up at maximum level is critical racing success. So when engine mechanics noticed their bronze distributor gear showed noticeable wear by race end, they knew vehicle performance was significantly degraded. The key question was whether or not material substitution could provide them with a longer lasting, higher performing gear.

Fortunately, the designers turned to Performance Plastics, LLC (PPL) for help. Working with Victrex plc, a supplier of high performance thermoplastic polymers, PPL developed an injection molded replacement for the conventional bronze alloy gear. As with most metal to plastic conversions, the first and most critical step is material selection. In this application, the part had to maintain structural rigidity at 120°C (250°F) operating temperatures while being subjected to oil and gasoline vapors.

Solution

PPL teamed with Victrex® technical development engineers to create a custom resin able to survive the high under hood operating temperatures and the abrasion from material to material contact.  Our collective efforts resulted in a unique carbon fiber filled PEEK compound embedded with additives obviating the need for additional lubricants.  PPL injection molds gear blanks to near net shape which are then finished by machining the gear teeth to the desired involute shape.  The injected molded PEEK gear is capable of maintaining a high level of its physical properties while operating close to its melt temperature of 343°C (645°F), well in excess of the requirement.

Results

The new gears were tested in a number of cars before being used in actual races. The gears were examined for surface cracks, chemical attack, distortion and abrasion. Initial testing showed no detectable wear in over twenty-four hours of racing. Additionally, the new gears provided an 81% reduction in part mass and inertia, helping to deliver faster throttle response and more horsepower to the drive wheels. After multiple years on the racing circuit, a single gear is now being used for an entire season, as opposed to being replaced after every race.
