![]() Contact Us to Learn More About PEEK Injection MoldingĬontact Springboard to learn how we can use PEEK resin in your injection molding projects. We provide unparalleled expertise in injection molding PEEK resin for medical devices and other applications. A final consideration is that while PEEK material properties make it CNC machinable, precautions must be taken to prevent stress damage when machining filled PEEK plastics.įortunately, Springboard has the skills, experience, and advanced machinery needed to effectively work with PEEK plastic in all our plastic injection molding processes. Since PEEK plastic is also sensitive to anisotropic shrinking during the cooling process the right amount of pressure needs to be applied to the mold to maintain product integrity. This requires special equipment that might not be utilized by all injection molding facilities. The first consideration is that PEEK material must be heated to very high temperatures at or above the highest range of most injection molding machines. 30 carbon-filled PEEK has greater thermal conductivity than unfilled PEEK. It is the grade with the optimum wear-resistance and load carrying characteristics. And as a result its expansion rate is dramatically lowered. Though it is a very popular engineered plastic for injection moulding, PEEK resin can also be difficult to work with and might not suitable for all applications. PEEK CF30 is enhanced with 30 carbon fiber.The compressive strength and stiffness of the material is enhanced. Special Considerations for PEEK Injection Molding In addition to standard injection molding, PEEK resin is also used in overmolding applications to fabricate reinforced components for aerospace and automotive. The high strength-to-weight ratio and heat tolerance of PEEK plastic makes it a popular choice for a wide range of applications including aerospace, biomedical, pharmaceutical, fiber optics, automotive, industrial, and more. Springboard works with a wide variety of materials in our injection molding processes. Unfilled PEEK is FDA-approved for food contact Email a Plastics Specialist.Suitable for continuous use in application temperatures up to 338☏/170☌.Very low smoke/toxic gas emission when exposed to flame.Excellent resistance to high pressure water & steam without significant degradation.Excellent fatigue & stress-crack resistance.High chemical resistance, even at elevated temperatures.PEEK plastic makes an excellent reinforcement material, providing great tensile strength with low weight.įeatures and benefits of PEEK material properties include: ![]() PEEK resin holds up well against high temperatures and long-term liquid submersion and is very durable in harsh environments. PEEK plastic exhibits superb mechanical properties and is highly resistant to chemicals and thermal degradation, making it a highly desirable material for plastic injection molded products. The versatility and superior mechanical properties of PEEK resin make it an ideal choice for medical, aerospace, mechanical and other demanding applications.Ĭontact a Molding Expert PEEK Molding Services Injection molded PEEK parts can also be an effective replacement for machined metal parts in a broad range of other uses. This unique, high-performance thermoplastic is ideal for medical applications because of its tolerance to gamma radiation exposure and sterilization processes such as autoclaving. ![]() Some of the properties of 450G and 150G are compared in the table below to illustrate these differences.PEEK (polyether ether ketone) is one of the most useful, versatile, and popular injection molding resins available. This is a consequence of the shorter polymer chains, which are less entangled, crystallise more readily and to a greater overall extent. However, the lower molecular weight also changes the bulk properties of the polymer: lower molecular weight PAEKs have higher stiffness and strength combined with reduced toughness, ductility and impact resistance. As a result, 150G may be more suitable for applications where lower viscosity in the melt during processing is desirable, for example, when injection moulding thin-walled parts or long, thin sections with intricate geometries impregnating carbon or glass fibres for composite prepregs or adding high levels of solid fibrous or particulate fillers and reinforcements to make compounds. VICTREX PEEK 150G is a higher flow, lower molecular weight, lower MV grade of PEEK compared to 450G. Other VICTREX PEEK grades are available with higher and lower melt viscosities and higher or lower molecular weights respectively. VICTREX PEEK 450G is defined as a standard melt viscosity (MV) PEEK grade, with a medium molecular weight. ![]()
