Charger Housing Injection Molding Services

The shell of mobile phone chargers is usually made of acrylonitrile-butadiene-styrene plastic (ABS), which has the following characteristics: the overall size is medium to large, and the average thickness of the entire plastic part is about 2 mm.

According to the analysis of OEM Plastic Moulding Supplies Manufacturer, the injection molding process of mobile phone charger shells is as follows:

1. Material and structure analysis

The ABS material used in the mobile phone charger shell makes the overall size of the plastic part medium to large, and the average thickness is usually 2 mm. The internal structure is designed with reinforcing ribs and a more complex shape. There are positioning holes at the rear, and the arc transition design is used around to improve the overall appearance and strength.

2. Appearance and performance

The outer surface of the plastic parts of the charger injection molding is smooth, without welding marks and spots. The matching accuracy requirements of the positioning holes of plastic parts are not high, but they must have good mechanical properties to ensure a certain elasticity and strength so that they are not easily deformed during use.

3. Production process optimization

Combined with the size characteristics of the mobile phone charger shell, OEM plastic injection molded parts suppliers recommend the use of a one-mold multi-cavity injection molding method to improve production efficiency. In addition, according to the design of the outer surface of the plastic part, the gate should be set at the bottom of the plastic part to reduce the visual impact.

4. Mold design and precision control

In the mold design, the largest edge of the plastic part is selected as the parting surface, and the positioning holes on both sides are processed laterally. This design can effectively improve the production efficiency of injection molded parts. Through the injection molding process, we can meet the strict requirements of size and surface roughness, thereby improving the overall product quality.

Through the above analysis, OEM plastic injection molded parts suppliers not only pay attention to the selection of materials and structures in the injection molding of mobile phone charger shells, but also optimize the production process to ensure the high quality and high performance of the final product.
