High-temperature material forming (PSU/PPSU/PEI/PEEK)
Craftsmanship introduction
High-temperature injection molding is a specialized advanced technology for processing high-performance thermoplastics. As traditional engineering plastics often fail to meet demands in critical applications due to limited heat resistance, strength, or chemical tolerance,the need for high-temperature polymers such as PSU, PPSU, PEl, and PPS+GF40 has grown. These materials feature extremely high glass transition temperatures and melting points, requiring processing at barrel temperatures reaching 200℃ or above. This process ensures precise control throughout molding, preserving the superior properties of these polymers in the final product. Key application contexts include:
■ Lightweighting & Metal Replacement:
Driven by the need to reduce weight and save energy in aerospace and high-end automotive sectors, where high-temperature plastics offer metal-like strength and heat resistance alongside design flexibility and corrosion resistance.
■ Stricter Safety & Reliability Standards:
Increasing demands for flame retardancy, creep resistance, and long-term reliability in electrical, electronic, and transport applications make materials like PEl and PPS preferred for components such as breakers, sensors, and connectors.
■ Proliferation of Extreme Environments:
Components must endure high temperatures, corrosive conditions, or repeated sterilization in fields such as new energy vehicle powertrains, green hydrogen production, and medical devices, expanding the use of PPS, PSU, and PPSU.
