Polyoxymethylene (POM/Acetal)

Withstanding prolonged exposure to alkaline detergents and hot water without hydrolytic breakdown requires a specialized acetal copolymer, which Celcon M90 by Celanese delivers through its stable polyoxymethylene copolymer matrix. Featuring a density of 1.41 g/cm³ and a melt index of 9.0 cm³/10 min, this unreinforced grade offers superior hot-water stability and far lower mold plate-out (deposits) during continuous production than homopolymer acetals. At Jucheng Precision, an ISO 9001, ISO 13485, and IATF 16949 certified manufacturer, we specialize in molding Celcon M90. Using our in-house 5-axis CNC-machined S136 stainless steel molds, we control its 1.8% to 2.2% shrinkage, delivering dimensionally stable water valves verified by Zeiss CMM.

Enduring intense, repeated physical impact and long-term structural load in high-stress moving mechanisms requires ultimate toughness and creep resistance, which Delrin 100P by Delrin USA (formerly DuPont) delivers through its high-viscosity, high-molecular-weight homopolymer acetal matrix. Boasting a density of 1.42 g/cm³ and a low melt flow rate of 2.4 g/10 min, this unreinforced grade offers exceptional elongation at break (over 40%) and unmatched impact toughness (notched Charpy of 13 kJ/m²). At Jucheng Precision, an ISO 9001 and IATF 16949 certified contract manufacturer, we specialized in high-pressure molding of Delrin 100P. Backed by 35+ advanced injection presses and five-axis CNC-machined H13 tooling, we control its high crystallization shrinkage (1.8%-2.2%) and eliminate gas traps, delivering structurally flawless parts verified by Zeiss CMM.

To achieve maximum mechanical fatigue resistance and metal-like rigidity in precision gear and sliding components, Delrin 500P by Delrin USA (formerly DuPont) stands as the global homopolymer POM benchmark. Featuring a density of 1.42 g/cm³ and an intermediate melt flow rate of 15 g/10 min, this highly crystalline acetal polymer provides significantly higher tensile strength and stiffness than typical acetal copolymers. Jucheng Precision, operating under ISO 9001 and IATF 16949 certified frameworks, specializes in high-precision molding of Delrin 500P. Backed by 35+ advanced injection presses and five-axis tooling, we master its high shrinkage (1.8%-2.2%) to deliver pristine, zero-flash gears verified by Zeiss CMM.

Maintaining a perfect equilibrium between long-term sliding wear resistance and high dimensional stability in high-tolerance kinematics requires a highly balanced acetal copolymer, which Polyplastics' Duracon M90-44 delivers. Boasting a density of 1.41 g/cm³ and a stable melt index of 9.0 g/10 min, this standard grade is globally recognized for its exceptional friction properties, low wear factor, and creep resistance. Jucheng Precision, under IATF 16949 and ISO 9001 frameworks, specializes in molding Duracon M90-44 for complex automotive and consumer assemblies. Using our 5-axis CNC-machined S136 tool cavities and 35+ advanced presses, we control its 1.8% to 2.2% shrinkage, delivering zero-defect gears verified by Zeiss CMM.
