![]() ![]() Resistance to wear and tear: PEEK and PPS both have excellent resistance to wear and tear, which can increase the longevity of parts and reduce maintenance costs. Injection moulded parts made from PPS can provide excellent insulation properties, which can help to protect sensitive electronic components. This makes it an excellent choice for medical device manufacturers who need to create parts that are both strong and biocompatible.Įlectrical insulation: PPS is an excellent electrical insulator, which makes it ideal for use in electrical and electronic applications where insulation is critical. This can be especially beneficial in applications where weight is a concern, such as aerospace or automotive applications.īiocompatibility: PEEK is biocompatible, meaning that it is compatible with human tissue and can be used in medical applications such as implants. Lightweight: PEEK and PPS are both lightweight materials, which can reduce the overall weight of the finished product. ![]() This means that each part will be identical to the next, which is important in applications where consistency is critical. Precision and repeatability: Injection moulding allows for the creation of highly precise parts with excellent repeatability. Injection moulded parts made from these materials can withstand high temperatures and exposure to corrosive chemicals without degrading, which can increase the longevity of the parts and reduce maintenance costs. Resistance to heat and chemicals: PEEK and PPS both have excellent resistance to heat and chemicals, making them ideal for use in harsh environments. Injection moulded parts made from these materials can withstand high loads and stresses without deforming or breaking, making them ideal for use in high-stress applications. High strength and stiffness: PEEK and PPS are both known for their exceptional strength and stiffness. There are many benefits to using injection moulded parts made from PEEK and PPS, some of which include: It is often used in automotive, electrical, and electronic applications due to its excellent electrical insulation properties and resistance to corrosion. PPS, which stands for polyphenylene sulfide, is another high-performance engineering thermoplastic that is known for its excellent mechanical properties, high heat resistance, and chemical resistance. PEEK is often used in aerospace, automotive, and medical applications due to its high strength-to-weight ratio, biocompatibility, and resistance to wear and tear. It has excellent chemical resistance, which makes it ideal for use in harsh chemical environments. PEEK, which stands for polyetheretherketone, is a high-performance engineering thermoplastic that is known for its exceptional strength, stiffness, and heat resistance. ![]() However, considering the immense advantages of these plastics, it is worth exploring how and why they are excellent candidates for injection moulding. Two materials that are less commonly used in injection moulding are PEEK and PPS. They also have very predictable melt-flows and shrinkages, meaning that a part can be quickly developed using off-the-shelf metrics that can usually be provided by the raw material suppliers. Not only do they melt at relatively low temperatures (anywhere between 150-175☌) but they are also fairly easy to handle when liquid, as they do not give off any corrosive gaseous effluents. Well known polymers – such as polypropylene, polyethylene, and even nylons – are relatively easy to handle in this process. Because the process involves taking the polymer into a molten state and maintaining it there until it is injected into the mould, it requires careful consideration and equipment that is capable of managing the polymer in its liquid state. This process is ideal for producing high-volume, complex components with great precision and repeatability. Injection moulding is a widely used manufacturing process that involves the creation of parts and products by injecting molten material into a metal mould. ![]()
