Surface Finishing – Polish / Texture

Surface finishing is a crucial step in electronics panel manufacturing, directly impacting both appearance and performance. Common treatments include polishing and texturing. Polishing enhances surface smoothness and gloss, while texturing creates patterned finishes that improve aesthetics and functional performance.

The Parting Line Design Of Electronics Panel

When designing the electrical bracket parting line, our mold designers consider mold opening direction and demolding methods to ensure a clean appearance. Parting lines are placed in hidden or edge areas to avoid visible surfaces and preserve the product’s overall aesthetics. The red lines indicate the parting lines.

The Draft Angle Analysis Of Electronics Panel

In injection molding, the draft angle is crucial for smooth demolding of the electrical bracket. It is the angle between the mold surface and the bracket’s vertical direction. A properly designed draft angle reduces friction during demolding, preventing scratches, deformation, or surface damage.

Sub-Insert Design

In injection mold design, sub-inserts are used to address complex geometries, high-precision areas, and wear-prone features. These removable components are embedded in the main cavity or core, improving mold flexibility, accuracy, and service life. Marking 1 indicates the cavity sub-insert, and marking 2 indicates the core sub-insert.

Gate Type & Location & Size of Electronic Panel

In injection mold design, gate type, location, and size play a critical role in product quality and productivity. Common gate types include point, side, submarine, and fan gates, each suited to different part sizes and appearance requirements.

Gate location is typically selected in thicker wall areas to ensure uniform filling, reduce weld lines and air traps, and avoid critical functional zones. For electrical brackets with high cosmetic requirements, submarine gates are used.

Gate size is determined by material flow properties and part geometry to ensure smooth filling without defects. Proper gate design optimizes molding performance, improves appearance, and enhances production efficiency.

The Problem Points of Electronics Panel

There is an undercut in this part, which we recommend modifying as shown in the picture. This undercut design may cause difficulties in the demolding process, thus affecting productivity and electrical bracket product quality. By making the suggested modification as shown in the picture, the mold design can be optimized to improve the smoothness of the process and the pass rate of the final product. This modification will help avoid potential production problems and ensure that parts can be demolding from the mold more smoothly.

Reasonable mold layout design is the basis for achieving high-quality injection molding. By optimizing various aspects such as cavity and core layout, gating system, ejector system, cooling system, parting surface, and venting system, the working efficiency of the mold and the quality of the product can be improved. The mold layout design needs to take into account the shape, size, material properties, and production requirements of the electrical bracket, to achieve the best production results.

Before delivery, we will fully maintain and clean the molds to make sure the surface of the molds are smooth and internal impurities. Then anti-shock material and protective padding are packed and put into wooden crates and labeled with model and quantity information.
