POM-Polyplastics Duracon M90-44 Blueprint<\/h2>\n

Molding a standard copolymer resin like Duracon M90-44 requires precise mold cooling to manage isotropic shrinkage, alongside corrosion-resistant tool face designs:<\/p>\n

\n
\n

S136 Hardened Steel Core<\/p>\n

At melt temperatures, POM copolymers release minor formaldehyde outgassing. Jucheng\u2019s tooling division uses hardened, corrosion-resistant S136 stainless steel molds and machines highly ventilated vents (0.015mm to 0.020mm) to prevent mold face corrosion and secure clean parting lines.<\/p>\n<\/div>\n

\n

Crystalline Shrinkage Compensation<\/p>\n

Duracon M90-44 exhibits high, isotropic shrinkage (typically 1.80% to 2.20%). We employ conformal cooling loops machined on our 5-axis CNCs directly into core block inserts, ensuring uniform heat dissipation across deep rib gates to prevent warpage and shrink voids.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
