The car grille is a mesh part with a grid in the front part of the car. The front grille of the vehicle is located between the front bumper and the front cross member of the vehicle body. Since the hood lock needs to be arranged on the upper surface area of the front grille, the front grille needs to have a hood lock avoidance hole to avoid the hood lock.

Surface Requirements for Types of Automotive Grille Parts

Automotive grille parts refer to a more grid-like structure on the main structure of the product, with through holes in the middle of the grid.

Such parts generally refer to the engine intake grille (radiator grille), bumper decorative grille, the buffer grille inside the car.

The buffer grille is a functional part and is generally not seen by the user in the interior of the car.

The air intake grille (radiator grille) and bumper grille are exterior parts, and the most important thing is the surface quality.

The surface treatment of the air intake grille generally includes skin texture, sandblasting, painting, electroplating, and the materials usually use PP, ABS, ASA, etc.

The bumper grid pattern is sandblasted, mainly PP material. Limited by product structure, it is difficult to eliminate weld marks.

How to control the location of the weld line is the most important issue for this type of product.

Precautions For Automotive Grille Mold Design

According to the shape of the mesh, the automotive grille can also be divided into the irregular grille and square hole grille. The welding line problem of the square hole automobile grille is more prominent, but it is also easier to solve these problems in the mold structure. The grids in the two directions of the square-hole automobile grille are usually different. One direction is the main body, and the other direction is the stiffener at the secondary position. It is easy to pay attention to the weld marks in the main direction, so the weld marks should be located in the second position as much as possible.

The parting line of the automobile grille is more complicated, and the parting surface needs to be designed according to a certain rule, not at will, to avoid molding problems. The draft angles at the grid position is usually not large, so the design should be checked according to the surface treatment requirements. If the ribs are on both of cavity side and core side, it is necessary to focus on verifying the respective draft angles of the cavity and core. Generally, the draft angles of the cavity side are larger than the core side to avoid the product will be stuck to the cavity side of mold.
