Plastic mold structure mainly includes the combination concave die, die with variable cavity combination of substrate and the substrate, concave die die composite substrate, with variable core punch, punch combination of substrate, punch combination cutting substrates, cavity components and lateral composite substrate.
to improve the performance of the plastic can also add filler in polymer, plasticizer, lubricant, stabilizing agent, colorant, and other auxiliary material, make polymer of high performance plastics.
synthetic resin is the main component in plastic, its content is commonly 40% ~ 100% in plastic. Because the amount of resin is very big, and its property is one of the properties of plastic, so often seen as synonymous with plastic resin. PVC resin and PVC plastic, for example, the difference between phenolic resin and phenolics. In fact, resin and plastic are two different concepts. The unprocessed raw polymers not only used in the manufacture of plastic, also can be used as coating materials, adhesives and synthetic fiber. And plastic in addition to the tiny part containing 100% of the resin, the vast majority of plastic, in addition to the main ingredients resin, still need to add other material.
packing, also known as filler, it can improve the strength and heat resistance of the plastic, and can reduce the cost. Such as adding wood powder, phenolic resin can be greatly reduced cost, make bakelite a cheap plastic, at the same time, it can obviously increase its mechanical strength. Filling can be divided into two major categories of organic and inorganic materials, such as wood powder, and cloth, paper, and various kinds of fabric, the latter such as diatomite, asbestos, glass fiber, carbon black, etc.
plasticizer plasticizer can improve the plasticity of plastic and softness, reduce the brittle plastic, the plastic is easy to processing molding. Miscibility usually with resin, non-toxic, odourless, optical and thermal stability of the high boiling, is commonly used phthalates. For example, in the production of PVC plastic, if add more plasticizer, can get soft PVC plastic, if you don't add or less add plasticizer ( Use & lt; 10%) , you can get the hard PVC plastic.
stabilizers to prevent the synthetic resin in the process of processing and use of thermal decomposition, prolong service life, should be added in the plastic stabilizer. Commonly used in stearic acid salt, epoxy resin, etc.
colorants colouring can make plastic has many bright, beautiful colors. Usually used for organic dye and inorganic pigment.
lubricant lubricant is to prevent mold plastic molding without and metal bonding, at the same time, can make the plastic surface is smooth and beautiful. Ordinary lubricants such as calcium salt and magnesium stearate. In addition to the above additives, also can be added in the plastics flame retardants, foaming agent, antistatic agent, etc.
