What Is High Temperature Injection Molding?<\/h2>\n

high-temp polymer molding is a specialized manufacturing process that uses elevated melt temperatures\u2014typically above 300\u00b0C\u2014to process high-performance engineering thermoplastiques<\/a>1<\/a><\/sup>. In our factory, we run dedicated high-temperature machines for materials like PEEK, PPS, and PEI that simply can’t be processed on standard equipment.<\/p>\n

Standard injection molding typically operates at melt temperatures of 180\u2013280\u00b0C for commodity plastics like ABS, PP, and PE. High temperature molding pushes well beyond this range, requiring specialized barrel heaters, heat-resistant seals, hardened screws, and mold temperature controllers capable of maintaining mold surfaces at 150\u2013200\u00b0C. The payoff is access to materials that outperform metals in many applications\u2014at a fraction of the weight.<\/p>\n

What Materials Require High Temperature Processing?<\/h2>\n

Several families of engineering and high-performance polymers require processing temperatures above 300\u00b0C. We regularly work with these materials, and each has distinct processing requirements and performance characteristics.<\/p>\n

PEEK is the most requested high-temperature material in our shop. We’ve found that proper drying (150\u00b0C for 3\u20134 hours to below 0.02% moisture) and precise barrel temperature profiling are critical for producing defect-free PEEK parts.<\/p>\n

Standard machines typically max out at 300\u00b0C barrel temperature and 100\u00b0C mold temperature. PEEK requires 370\u2013400\u00b0C melt temperature and 160\u2013200\u00b0C mold temperature, demanding specialized barrels, heaters, and high-temperature mold controllers that standard machines don’t have.<\/p>\n<\/div>\n

Processing materials above 300\u00b0C requires barrel heaters rated for 400\u00b0C+, heat-resistant seals, hardened bimetallic screws, and mold temperature units (often oil-based) capable of maintaining mold surfaces at 150\u2013200\u00b0C for proper crystallization and surface quality.<\/p>\n<\/div>\n

What Are the Key Benefits of High Temperature Injection Molding?<\/h2>\n

The primary benefit is access to materials that deliver metal-like performance at 40\u201370% less weight. In our experience working with aerospace and automotive clients, high-temp polymer molding enables designs that simply aren’t possible with standard plastics.<\/p>\n
