Manufacturing & Engineering Capability

Dual centre feed three-plate die casting mould

Step 01: Product Design & DFM Review

We conduct Design for Manufacturing (DFM) reviews, evaluating wall thickness, draft angles, and parting lines to optimize part structure before mold creation.

Step 02: Precision Tooling Development

We coordinate mold design with local Ningbo tooling experts, running flow analysis and running trial productions to verify precise physical dimensions.

Step 03: High-Quality Production Setup

We oversee mass production including high-pressure die casting, precision post-machining (tapping & CNC milling), and specialized surface finishes.

Step 04: Engineering-Grade Quality Control

Every batch undergoes strict dimensional inspection using calipers/gauges, cosmetic checking, and required performance or salt-spray lifetime testing.
