Mold Designs

As auto inner product, door trims products have high requirements on the appearance.

Usually, it will be requested for texture. On the product, it can not appear welding line, ejector white mark, shrinkage mark, and deformation. Below are some points for car door trim molding design.

1. Reasonable door trims mold base, to ensure the mould for automotive bumper strength and length mould life.

2. Even cooling system, the distribution of the cooling water as much as possible, and it’s better for big diameter.

3. Ejection reasonable and safe. As usual, door trims molding for cars will have many ejector pins. In order to avoid the product deformation, we consider the balance of ejection and reset.

4. Reasonable parting surface, considering the convenience of door trim mould processing and assembling.

5. Rework of mold flow analysis, usually the gate location will affect the welding marks situation, to select a correct place, it’s quite important.


Mold Base Standard: HASCO, DME, LKM local standard, and will according to customer’s requirements.

Labor costs for removing the part from the mould for automotive bumper and separating runner scrap from the part are eliminated.

Most mold choose the hot runner,Possibility of contamination is lessened with no runners

During the plastic injection molding process, the molten plastics are monitored using sensors in the mold cavity that measure parameters like pressure and temperature

If needed, adjustments can be made in real time during the molding process to make sure that high-quality products are consistently produced
