  The structural design of plastic product development should follow the following principles:   a. The structure design should be reasonable: the assembly gap is reasonable, and all plug-in structures should be reserved for gaps; ensure sufficient strength and rigidity (safety test), and properly design a reasonable safety factor.   b. The structural design of plastic parts should comprehensively consider the manufacturability of the mold, and simplify the manufacturing of the mold as much as possible.   c. The plasticity of the structure of plastic parts should be considered, that is, the injection molding production efficiency of the custom plastic injection molding companies should be high, and the rejection rate of injection molding should be minimized.   d.  Consider facilitating assembly production (especially not conflicting with assembly).   e. The structure of stamping plastic parts adopts standard and mature structure as much as possible, so...

  Compression molding is the operation of first putting powdered, granular, or fibrous plastic into the mold cavity at the molding temperature, and then closing the mold to press to shape and solidify it. Compression molding can be used for thermosetting plastics, thermoplastics, and rubber materials.   Advantages of compression moulding : (1) In the compression molding process, the loss of raw materials is small and will not cause too much loss (usually 2% to 5% of product quality).   (2) The internal stress of the product is very low, and the warpage deformation is also small, and the mechanical properties are relatively stable.   (3) The wear of the mold cavity is small, and the maintenance cost of the mold is low.   (4) The cost of molding equipment is low, and its mold structure is simpler, and its manufacturing cost is usually lower than that of injection molds or transfer molding molds.   (5) Larger flat products can be formed. The size of the produc...

  Rubber injection molding by Zhongde, a reliable supplier, can be used to produce both solid rubber parts and rubber bonding metal parts. It is an ideal process for mid-to-high volume rubber production. This is a process that is fully automated and becomes one of the most efficient ways to mold rubber in most cases.   Zhongde, a professional plastic and rubber injection molding companies   in China, is determined to provide customers with considerate services and superior products that meet high standards.   As a longtime injection moulding manufacturer for top-quality custom rubber parts, we are well-equipped to undertake a wide range of rubber materials, uphold precision tolerances within ± 0.5mm. Besides, we also offer overmolding and insert molding service to meet the ever-changing demands of our customers.   Guideline of Rubber Injection Molding Size of Rubber Injection Molding   Below table shows the size of Rubber Injection Molding parts we usually ...

  Zhongde, a reputable plastic and rubber injection molding company in China, also manufactures customized over-molding and china insert molding , with considerate services, to produce unique multi-material parts. Our production materials of custom over-molding and insert molding range from thermoplastic to elastomer-rubber, as well as metal and silicone. We've broken down the differences and similarities between the two processes. Let us help you decide which process is right for your project.   Both over-molding and insert molding injection processes by Zhongde, a reliable injection molding supplier, involve putting two types of materials together to make one part. And the inserts can be threaded metal inserts. China overmolding   is a two steps process that one to create the substrate and one for the oversold that goes on top of it. Insert molding is a slightly faster process as it takes only one step that the two materials are molded at the same time.   Guideline...
