Injection molding processing is a kind of plastic processing technology, in our life to carry forward great benefits, but through Changzhou injection molding processing of the finished product will also have shortcomings, speaking of this, the following to friends to explain the reason for this situation.

The size of injection molding should not only meet the requirements of use and installation, but also consider the processing and manufacturing of the mold, the performance of the equipment and the flow of raw materials. Strictly control the factors that affect the accuracy of injection molded parts, including the manufacturing accuracy of the mold, plastic components and process conditions. The surface roughness of injection molding is determined by the roughness of the mold surface, so the surface roughness of the mold is one level lower than that of the product, and the requirements are met by grinding and polishing. The injection molded parts will produce cooling shrinkage in the mold cavity, which makes it difficult to take out the injection molded parts. Therefore, in order to facilitate demolding, the design should also consider that the inner and outer surfaces parallel to the demolding direction have sufficient demoulding slopes.

Precision hardware can be cut according to production needs, and then some small accessories can be cut or CNC processed, and precision hardware must be used as a container for cutting and punching, followed by welding, then sanding, and oil injection. After the accessories are made done. It should be reminded that small parts also need to be electroplated or sprayed on the surface after grinding. There are many cases of batch processing of precision metal parts, so the production method and cycle of precision metal processing are different from the operating specifications and processes of general product processing.

Plastic mold is an abbreviation for a combined mold for extrusion, injection, compression, blow molding and low foam molding. The coordinated changes of the mold convex, concave mold and auxiliary molding system can process a series of plastic parts with different sizes and shapes.

Machining is suitable for parts, molds, models, etc., which are large, complex in structure, and processed with various materials. According to the different quantity and product structure of the product, the corresponding process can be selected and corresponding product solutions can be provided.

The prerequisite for the success of plastic molds is mainly reasonable plastic mold design. The design of plastic molds is relatively important, and the same structure can be produced in multiple ways.
