Amorphous Self-Extinguishing Molding Matrix<\/h2>\n

Molding an amorphous high-performance resin like Lexan 940A requires strict thermal boundaries and low-stress mold setups to prevent stress-cracking:<\/p>\n

\n

Contr\u00f4le du retrait isotrope amorphe<\/p>\n

Being an amorphous copolymer, Lexan 940A exhibits low and highly uniform shrinkage (0.50% to 0.70%). We use our 5-axis CNC machines to cut precise mold cavities and balance cooling paths, ensuring zero warping and zero dimension defects on Zeiss CMM verification.<\/p>\n<\/div>\n

\n

Profilage de temp\u00e9rature de fusion \u00e9lev\u00e9e<\/p>\n

Melting requires specialized machines with ceramic heater bands. Processing barrel temperatures are strictly managed between 280\u00b0C and 310\u00b0C (536\u00b0F to 590\u00b0F) to ensure homogeneous flow. Exceeding 320\u00b0C can result in chemical chain fracturing and polymer degradation.<\/p>\n<\/div>\n

\n

Desiccant Drying & Volatiles Exhaust (Hydrolysis Prevention)<\/p>\n

PC is highly sensitive to moisture at high melt temperatures. Wet molding results in rapid hydrolytic chain cleavage, causing severe splay, gas bubbles, and a major drop in impact strength. We desiccant dry Lexan 940A resin at 120\u00b0C (248\u00b0F) for 3\u20134 hours, keeping moisture below 0.02%.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
