Product introduction: Door panels are used as automotive interior parts, depending on the model,

Dimensions are different, the product size shown on the left: 1100*720*125mm, the shape of the product surface is complex, the number of inverted buckles is up to 40, the appearance of the product is extremely high, and the surface cannot have any weld lines.

Difficulties in mold technology:

1. The appearance of the product is extremely high. Therefore, the MOLDFLW is used to simulate the injection molding process in the early stage to ensure the rationality of the design of the pouring system, and the advanced needle valve hot runner system is adopted to ensure the adjustability of the injection molding system.

2, the product surface is complex in shape and large in size, which requires extremely high precision in CNC machining.

3, the number of product undercuts is up to 40, all adopt inclined roof structure, the fitter has the requirement of the oblique top assembly process, and the inclined top movement must be smooth.
