Precise control of process parameters is essential for successful PPS molding. Below are key guidelines based on TONGDA LINK’s decade-long expertise in PPS mold design and production: The melting point of PPS material is about 285°C, but its melting temperature is usually between 260°C and 350°C. Therefore, the injection molding temperature must be controlled above the melting […]
Top/Bottom Shell Mismatch Tolerance (Stepping) After assembly, at the seam stop position: Surface Stepping (Top Shell Scraping): If the top shell protrudes beyond the bottom shell. Acceptable Limit: < 0.15mm. Bottom Stepping (Bottom Shell Scraping): If the bottom shell protrudes beyond the top shell. Acceptable Limit: < 0.10mm. Design Recommendation: Some level of mismatch is inherent. To minimize visible surface stepping, design […]
Achieving Uniform Wall Thickness in Injection Molding However, product designers often face significant challenges. Functional demands, structural requirements, and aesthetic considerations across consumer, medical, aerospace, defense, and industrial applications can make uniform wall thickness difficult to achieve. Consequently, mold engineers play a critical role in translating complex designs into manufacturable parts. They must strategically refine […]
