JinYi Mould successfully customized and delivered this series of molds for BYD, a leading Chinese automaker, for the production of integrated automotive interior molds—specifically, the dashboard storage cover mold series. The core challenge was ensuring these prominent interior components possessed superior surface aesthetics and precise dimensional accuracy within ±0.03 mm, enabling seamless assembly and guaranteeing their functionality on a high-quality dashboard.
We have a professional engineering team of over 500 people and an ISO 9001 quality management system, providing a systematic solution from simulation to manufacturing: optimizing parts and processes through design for manufacturability and mold flow analysis; achieving precision mold manufacturing using high-precision CNC and EDM equipment; and utilizing our 18 injection molding machines with clamping forces ranging from 80 tons to 1600 tons for production.
Advanced mold flow analysis (Moldflow) was performed on the thin-walled areas of the cover to predict and optimize fill patterns, eliminate weld lines, and control warpage. The analysis results directly guided the design of the final gate and cooling system.
The mold design is compatible with various surface treatment requirements, such as VDI/MT standard textures and mirror polishing. A balanced cooling circuit and precision ejection system ensure high surface quality even in high-volume production.
The mold integrates a precision slider and tilting cap mechanism, enabling stable formation of various undercut and snap-fit structures, ensuring consistent assembly strength and reliable demolding performance throughout the mold's lifespan.
Quality control strictly follows internal specifications conforming to automotive industry standards, with the following process:
A structured mold trial process from T0 to T3 verifies molding stability, shrinkage consistency, and assembly compatibility, ultimately determining the optimal process.
Trial samples must be precisely inspected using a 3D coordinate measuring machine (CMM) to ensure that critical fits and functional dimensions meet standards and requirements, specifically tolerances of ±0.03 mm, consistently and reliably.
Assembly testing is conducted on the final parts and matching dashboard components to verify their smooth and seamless integration into the overall vehicle assembly
The molds are delivered as a turnkey solution, accompanied by a complete production trial report, full-size inspection records, and technical documentation, ensuring the customer can achieve stable mass production smoothly and quickly.
This case study fully demonstrates JinYi Mold's ability to provide automotive brands with interior molds that meet high precision and high surface area requirements.
