Family Molds

Surface Finishing – Polish / Texture

The pink surface of picture 1 and picture 2 are textured. Texturing is done by forming regular or irregular patterns and textures on the plastic surface to achieve aesthetic and functional purposes. The blue surface is line polished which is the meticulous grinding and polishing of the mold surface using polishing tools and abrasive materials.

Parting Line Design

When designing the parting line of the electronic lid and electronic bracket, our mold designers will consider the opening and mold closing direction and mold demolding way, to ensure the aesthetics of the electronic lid, the parting line will be designed in an inconspicuous place or the edge area of the product, to avoid the parting line appearing in the front of the product or important visual area, so as not to affect the overall aesthetics of the product. The red lines are parting lines.

Draft Angle Analysis 

The draft angle design is critical to ensure smooth demolding. Correct design of the draft angle can prevent excessive friction between the product of electronic lid and electronic bracket and the mold surface during the demolding process, avoiding scratches, deformation, or damage to the custom front panel product surface. As the picture shows the draft angles of mark 1 and mark 2 are okay, and the draft angle of mark 3 around the part can be confirmed by texture type.

Ejector Design of Family Molds Parts

In the family molds design, The ejector system is responsible for ejecting the molded part from the mold safely and efficiently, ensuring that the product is not damaged and maintaining high accuracy. In the ejector design, we consider the shape, size, material, and demolding difficulty of the product of the electronic lid and electronic bracket to select the appropriate ejector method and ejector device. In the electronic lid mold, we use the Ø4 ejector pin to eject the product of the electronic lid and electronic bracket.

Gate Type & Location & Size

In the family molds design, we used a cold runner system with banana gate. The gate size is ∅1mm. To prevent the gate residue from protruding on the product surface, we designed a concave ∅3.0×0.5mm for the gate. This design helps to hide the excess material and keep the surface of the product flat and beautiful. However, due to the location of the gate and flow characteristics, slight flow marks may occur close to the gate. We will make necessary adjustments and optimizations during the production process to avoid affecting the overall effect of the product.

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 custom front panel, 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.
