The design and manufacture of injection molds are closely related to plastic processing. The success or failure of plastic processing depends largely on the effectiveness of mold design and the quality of mold manufacturing, and the design of injection molds is based on the correct design of plastic products.
The following is an introduction to the design elements of injection molding services.
Parting surface
Structural parts
Mold accuracy
Pouring system
Plastic shrinkage rate and factors affecting the dimensional accuracy of the product
Parting surface
The parting surface is the contact surface where the concave mold and the convex mold fit together when the injection mold is closed. Its location and form are influenced by the shape and appearance of the product, wall thickness, molding method, post-processing process, mold type and structure, demolding method and molding machine structure, etc. The injection molding service provided by our company pays much attention to this aspect of design.
Structural parts
Structural parts are the slider, slant top, and straight top blocks of complex molds. The design of structural parts is very critical, which is related to the life of the mold, processing cycle, cost, product quality, etc. Therefore, the design of the core structure of complex molds requires a high level of comprehensive ability of the designer to pursue a simpler, more durable, and more economical design solution as much as possible. Our company's injection molding service provides structural parts that are very user-friendly.
Mold accuracy
Mold accuracy means avoiding card, precise positioning, guide pillar, positioning pin, and so on. The positioning system is related to the appearance quality of products, mold quality, and life, according to the different mold structures, choose different positioning methods, positioning accuracy control mainly relies on processing, internal mold positioning is mainly the designer to fully consider, design a more reasonable and easier to adjust the positioning method. Our company provides high precision injection molding service.
Pouring system
Pouring system is the feeding channel between the injection molding machine nozzle and the cavity, including the main flow channel, the diversion channel, the gate, and the cold cavity. In particular, the location of the gate should be selected to facilitate the molten plastic in a good flow state filled cavity, attached to the product of the solid runner and gate cold material is easy to eject from the mold and be removed when the mold is opened (except for hot runner mold).
Plastic shrinkage rate and factors affecting the dimensional accuracy of the product
Many factors affect the dimensional accuracy of products, such as mold manufacturing and assembly errors, mold wear, etc. In addition, when designing compression and injection molds, the process and structural parameters of the molding machine should be considered to match.
