Product Description:
The size of the auto grille mould is large, and the rear mould has many flat tops or small diameter thimbles, which is difficult to process, so it needs to be inlaid. The parting line of the grille is relatively complex, and the parting surface needs to be designed according to certain rules, which cannot be modified at will.
If there are ribs on the front and back of the car grille mould, we need to focus on checking the respective demoulding slopes of the front and rear moulds. Generally, the front mould is larger than the rear mould to prevent the product from sticking to the front mould.
The grid of grille products has many through holes, and the shape and parting line change complexly, so there are many small positions on the mould, so as long as the product allows, the automobile grille mould should be processed by inlaying as much as possible.
For grid products with complex shapes, the gate arrangement should be considered as a whole, but it is difficult to accurately control the weld line. Hot runner systems generally use sequential needle valve gate control to adjust the position of the weld line.
