Insert Molding

Surface Finishing – Polish / Texture

Surface Finishing is a critical part of the insert molding program, ensuring that the final product has excellent appearance and performance. Through surface finishing, we can improve the aesthetics, abrasion resistance, and corrosion resistance of insert molding parts.

Parting Line Design of Insert Molding Parts

When designing the electrical bracket parting line, our mold designers will consider the opening and mold closing direction and mold demolding way, to ensure the aesthetics of the electrical bracket, 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, and blue lines are parting lines of sliders.

Draft Angle Analysis of Insert Molding Parts

Draft angle analysis in DFM ensures smooth demolding by evaluating the product’s geometry for adequate taper. It identifies areas lacking draft angles, preventing defects like scratches or deformation during ejection. This analysis optimizes mold design, reduces wear, and enhances production efficiency while maintaining part quality and consistency.

Sub-Insert Design of Insert Molding Parts

Sub-insert design plays a vital role in insert molding mold design, especially in the manufacture of products that require high precision and complex geometries. Inserts are part of the mold and can be separate components used to form specific product details or features. The 1 marking is the core pin.

Ejector Design of Insert Molding Parts

Ejector design is a crucial part of insert molding mold design, and its main purpose is to ensure that the electrical lid can be smoothly de-molded from the mold without damage. 

Gate Type & Location & Size

We used a YUDO hot nozzle system to mold this part, and the diameter of the injection port at the 1 place is Ø1.2mm. To optimize the injection effect and ensure that the material can flow into the cavity smoothly, we suggest making a depression at the injection port in the second place, with a dimension of φ5X0.5mm. This design of depression can effectively reduce the stress concentration that may occur during the injection process, improve the material flow, and ensure that the surface of the molded part is smooth and free of defects.

This design can effectively reduce the stress concentration that may occur during the injection process, improve the material flow, and ensure that the surface of the molded part is smooth and free of defects. In addition, this design also helps to control the cooling rate of the molten plastic, preventing premature curing and further improving the quality and consistency of the electrical lid.

Reasonable custom front panel 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.
