Key Evaluation Indicators for Sourcing Low Pressure Die Casting Mold from China Foundry Tooling Manufacturers
Professional evaluation of Chinese casting mold suppliers focuses on mold lifespan, precision stability, delivery efficiency and technical service capability with quantifiable industry indicators.
Lifespan is the core evaluation index for low pressure die casting mold, with qualified China-made molds achieving 50,000-80,000 stable casting shots under standard working conditions.
Dimensional precision stability of LPDC mold is measured by continuous production error, with qualified products maintaining error below 0.02mm after 30,000 production cycles.
Wheel casting mold surface finish directly affects casting appearance quality, with standard automotive molds reaching Ra0.8μm finish level without secondary polishing.
Custom low pressure die casting mold evaluation must include heat treatment parameters, with HRC 50-52 hardness being the optimal range for aluminum wheel production molds.
High durability LPDC die for mass production needs verified thermal simulation data, covering 100% of cavity temperature and cooling flow operation parameters.
Aluminium alloy casting mould delivery qualification rate is a key sourcing indicator, with excellent manufacturers maintaining a 98.5% one-time delivery pass rate.
Automotive casting tooling suppliers need independent mold testing workshops, completing full performance tests before product delivery.
Foundry tooling technical service capability is evaluated by problem solving efficiency, with professional teams completing mold debugging within 3 working days overseas.
A356 aluminum alloy casting supporting molds must have good thermal fatigue resistance, with no obvious cracks after 200 times of rapid temperature change tests.
xinfeng’s mold products pass full-index industry testing, meeting the quantitative evaluation standards of global mainstream foundry enterprises for imported molds.
