Jucheng Precision, operating under ISO 13485 and IATF 16949 certified frameworks, specializes in high-temperature molding of KetaSpire KT-820. Supported by high-temperature ceramic heater bands and oil-heated tooling controllers, we ensure complete semi-crystalline phase alignment, delivering structural components verified by Zeiss CMM.
Achieving high mechanical integrity and chemical resistance in complex, thin-walled geometries requiring long flow lengths demands an ultra-flow super-polymer, which Victrex’s PEEK 150G delivers through its unreinforced, low-viscosity polyetheretherketone matrix. Boasting a melt viscosity of 130 Pa·s at 400°C and a melting point of 343°C, this easy-flow grade is designed to fill sub-millimeter profiles without sacrificing the high tensile strength (105 MPa) of pure PEEK. Jucheng Precision, under ISO 13485 and IATF 16949 medical and automotive frameworks, specializes in molding Victrex 150G. Using S136 stainless steel molds, we control its high crystallization variables to deliver flash-free micro-gears and thin-wall connectors verified by Zeiss CMM.
Replacing aerospace-grade titanium and high-strength aluminum alloys in severe, load-bearing dynamic mechanisms without adding weight requires a polymer of unmatched specific stiffness, which Victrex’s PEEK 450CA30 delivers through its 30% carbon fiber reinforced, semi-crystalline polyetheretherketone matrix. Boasting a density of 1.40 g/cm³ and an extreme heat deflection temperature (HDT) of 335°C, this high-performance composite provides a massive flexural modulus of 21,000 MPa alongside inherent electrostatic dissipation (ESD) and near-zero wear. Jucheng Precision, operating under IATF 16949 and ISO 13485 certified frameworks, specializes in molding PEEK 450CA30. Supported by ceramic heater bands and pressurized oil mold heating controllers, we control its anisotropic shrink variables to prevent warpage, delivering structurally flawless parts verified by Zeiss CMM.
