Complex parts and products often require highly engineered, lightweight thermoplastics with enhanced strength and flexibility – plus temperature, corrosion and wear resistance. Learn what's involved in creating these high-performance parts by downloading our whitepaper, Processing High-Temperature and Engineered-Grade Resins. In it you’ll find important insights about:

  • Physical properties of popular high-temp plastics and their applications
  • Achieving full crystallinity at temperatures that can exceed 700°F
  • Specialized equipment required for molding high-temp resins
  • The importance of carefully controlling heating and cooling during molding
  • Why proper gate location is critical, especially for high-temp plastic parts and products
  • Methods for drying raw materials prior to injection molding
  • Safety requirements for ensuring safe injection molding at excessive temperatures

Sneak Peek Inside the Whitepaper:

More customers are asking about making complex parts and products from high-temperature resins for high temperature applications (for example, replacing metal automotive parts in high temperature operating environments with lightweight plastic parts). In elevated temperature applications, these plastics can hold tolerances of +/-.0005 inches without affecting dimensional stability. Other physical benefits of high-temperature resins include enhanced chemical resistance. For example, because of its excellent resistance to hydrolysis, the high-temperature plastic polysulfone is ideal for replacing brass in water fixtures.

Although high-temperature resins are more expensive than commodity-grade resins, they can greatly improve product performance and durability, thereby reducing overall production costs. Metal parts that require expensive, high-precision machining, for example, can often be replaced with plastic parts—this reduces production costs, saves time, and improves corrosion resistance. In many cases, the high-temperature plastic part will cost less than its metal counterpart because once the mold is made and fine-tuned, large volumes of parts can be quickly and easily produced—a much more time- and cost-efficient process compared to machining individual metal parts. Also, because of their corrosion resistance, plastic parts eliminate the need for secondary finishing operations that would normally be required for metal parts.
