Automotive Grille Injection Mould

The size of the automobile grille mold is large, and the rear mold has many flat tops or small-diameter ejector pins, making it difficult to process, so it requires inlay processing. The parting line of the grille is complex, and the parting surface needs to be designed according to certain rules and cannot be arbitrarily designed to avoid problems with the mold. The draft of the product grid is usually not large, so it must be verified according to the surface treatment requirements during design. If the product has ribs on the front and rear molds, you need to focus on checking the draft angle of the front and rear molds. Generally, the front mold should be larger than the rear mold to avoid leaving the front mold in the product. Grating products have many holes in the grid and complex changes in shape and parting line, so there are many small positions on the mold. Therefore, as long as the product allows, the mold should be inlaid as much as possible to facilitate processing. For grating products with complex shapes, the overall gate layout must be considered first, but it is difficult to accurately control the weld marks. Hot runner systems generally use sequential raft control to adjust the position of the weld lines.

Process of Producing a Custom Plastic Mold

There is a step-by-step process to making plastic injection molding parts. And as with most things, it first starts with the design.

Mold design

The mold design process is crucial--Here is where you hash out all the ideas and talk about the different needs for your project. A poor design can ruin your custom plastic injection molding project. And it will also cost more compared to a well-designed DFM design.

Mold manufacture

After the design process, it is time to manufacture the mold, where the expertise of a molding supplier usually shows. There are mainly five steps to produce a mold:

CNC machining: In this procedure, the digital milling machine uses a rotating cylindrical tool to cut workpieces accurately, versatilely, and fast to get the desired shapes.

EDM machining: EDM machining stands for electro-discharge machining or spark-machining. In this process, a particular shape is obtained by using electrical discharges. This process is also called wire cutting.

Lathe Machining: Lathe machining is a precise machining procedure. It can perform operations like changing the surface roughness, weak resistance, visual properties, and chamfer the mold's features.

Mold Fitting: This is one of the most critical processes of custom plastic injection molding. It requires expertise where mold pieces are put together to form a perfect shape or mold.

Mold Polishing: This technique helps increase the smoothness of the mold and makes the products easier to demold. That can be done by horning which is usually conducted by whetstone, sandpaper, polishing paste, and wool wheel.

Mold Trials

The last stage in the custom plastic injection molding process is mold trials. You need to make sure that the mold you designed and manufactured works perfectly and as intended.

Without any trials, you might overlook critical and non-apparent design or manufacturing mistakes, which can be very costly down the line.

At Abery, we can design, produce, and examine products to provide the most suitable and cost-effective custom plastic injection molding for you.
