Mold is a variety of molds and tools used in industrial production to obtain required products by injection molding, blow molding, extrusion, die casting or forging molding, smelting, stamping and other methods. It is a tool for making molded articles. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of article shape by changing the physical state of the formed material.
Mold is a tool for making a blank into a workpiece with a specific shape and size under the action of external force. It is widely used in blanking, die forging, cold heading, extrusion, pressing of powder metallurgy parts, pressure casting, and compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The die has a specific contour or cavity shape. The blank can be separated (blanking) according to the contour shape by using the contour shape with cutting edge.

Engineering Support & DFM Analysis
DFM (Design for Manufacturability) Analysis
We thoroughly evaluate critical part geometries before cutting steel to prevent failures:
Wall thickness consistency
- Draft angles for smooth part ejection
- Optimum gate location and gating types
- Ejection pin layout and runner design
- Undercut analysis and slider/lifter mechanisms
- Potential sink marks and warp deformation risks
Mold Flow Simulation
Before manufacturing, we utilize advanced simulation software to analyze:
- Material filling behavior and balancing
- Injection pressure distribution
- Cooling circuit efficiency and hot spot identification
- Weld lines positioning and structural impact
- Air traps and venting optimization
Material Selection Assistance
We guide customers in selecting the ideal mold structure to match their target thermoplastic resins:
- Commodity Plastics: PP, PE, ABS, PS
- Engineering Plastics: PC, PA (Nylon), PA66+GF, POM, PET, TP
