Applicable Molding Processes for PSU\/PPSU<\/h2>\n

Amorphous sulfone polymers require precise melt shear and mold temperature settings during molding:<\/p>\n\n\n\n\n\n\n\n
Molding Process<\/th>\nProcess Suitability & Application<\/th>\n<\/tr>\n<\/thead>\n
Standard Injection Molding<\/td>\nExcellent. Configured with specialized wear-resistant, high-temperature barrels to mold medical sterilizing trays and baby bottles.<\/td>\n<\/tr>\n
Thin-Wall Molding<\/td>\nGood. Allows high-injection pressure profiles to fill precise plumbing manifold tees and diagnostic cartridges.<\/td>\n<\/tr>\n
Insert Molding<\/td>\nExcellent. The extremely low and isotropic shrinkage of amorphous sulfones prevents stress cracks when encapsulating brass hot-water pipe inserts.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/section>\n

PSU & PPSU Manufacturing & Tooling Guide<\/h2>\n

Sulfone polymers have high melt viscosity and are highly sensitive to moisture and internal molding stress. Execution of exact technical parameters is essential:<\/p>\n

    \n
  • Pre-Drying:<\/strong> Sulfone resins are highly hygroscopic. Moisture causes cosmetic splay, bubbles, and loss of transparent optical quality. We dry raw material in desiccant hopper dryers at 135\u00b0C\u2013150\u00b0C (275\u00b0F to 302\u00b0F) for 3\u20135 hours to moisture levels below 0.05%.<\/li>\n
  • \u7194\u81a0\u6eab\u5ea6\uff1a<\/strong> Handled between 320\u00b0C and 390\u00b0C (608\u00b0F to 734\u00b0F) for PSU, and 340\u00b0C to 390\u00b0C (644\u00b0F to 734\u00b0F) for PPSU. Requires machines equipped with high-temperature heating bands.<\/li>\n
  • Elevated Mold Temperature:<\/strong> Circulating oil heaters are used to maintain mold temperatures at 120\u00b0C\u2013160\u00b0C (248\u00b0F to 320\u00b0F). Maintaining high mold temperatures is critical to prevent high internal molding stresses and weld-line visibility.<\/li>\n
  • Internal Stress Management:<\/strong> High-viscosity amorphous resins are prone to molded-in residual stresses. We implement progressive cooling cycles during DFM to avoid micro-cracks. Post-molding annealing is performed when specified.<\/li>\n
  • Low Isotropic Shrinkage:<\/strong> Due to their amorphous structure, PSU\/PPSU exhibit low and highly uniform shrinkage (0.4% to 0.7%), ensuring excellent post-molding dimensional stability.<\/li>\n<\/ul>\n<\/section>\n
