Rilsamid AMNO Scientific Molding Requirements<\/h2>\n

While PA12 has the lowest moisture absorption among polyamides, its high molecular weight requires precise gate placement and thermal uniformity to prevent pressure drops and weld line separation:<\/p>\n

\n

1. S136 Mirror-Polished Molds (Weld Line Optimization)<\/p>\n

Due to PA12’s low viscosity, gate placement is key to preventing weld line separation on thin-walled couplers. Jucheng\u2019s tooling division uses premium S136 stainless steel hardened to 48\u201352 HRC, mirror-polished on our 5-axis CNCs. This ensures dynamic fluid components release cleanly without drag marks.<\/p>\n

2. Low Shrinkage Dimensional Control<\/p>\n

Rilsamid AMNO exhibits low and predictable shrinkage (0.50% to 0.70%). We machine balanced cooling circuits directly into core blocks using conformal geometries to optimize crystallization variables and maintain micro-tolerance diameters.<\/p>\n

3. Precise Melt & Die Temperature Controls<\/p>\n

Processing melt temperatures are maintained between 210\u00b0C and 260\u00b0C (410\u00b0F to 500\u00b0F). Mold temperatures are kept at 20\u00b0C to 60\u00b0C (68\u00b0F to 140\u00b0F) using pressurized water heaters to maximize mechanical toughness and prevent flash.<\/p>\n

4. Desiccant Pre-Drying Protocol<\/p>\n

Raw polymer must be dried in desiccant hopper dryers at 80\u00b0C\u201390\u00b0C (176\u00b0F to 194\u00b0F) for 4\u20136 hours to ensure moisture levels remain strictly below 0.05% to avoid hydrolytic splay and bubble formation.<\/p>\n<\/div>\n<\/section>\n
