Plastic mold manufacturer What are the basic structures of

The utility model relates to a punch with a variable core, which is mainly composed of a die combination base plate, a die assembly and a die combination card, a variable core and a punch combination base

Plate, punch assembly, punch combination card, die cavity cutting assembly and side cutting composite plate.

In order to improve the performance of plastics, various auxiliary materials such as fillers, plasticizers, lubricants, stabilizers, colorants, etc. are added into the polymer to prepare good plastics.

1. Synthetic resin is the main component of plastics, and its content is generally 40% - 100%. Resin is often considered synonymous with plastic because of its high content and

Properties determine the properties of plastics. For example, PVC resin and PVC plastic, phenolic resin and phenolic plastic mixture. In fact, resin and plastic are different

The concept of. Resin is an unprocessed raw material polymer, which is not only used to manufacture plastics, but also used as raw material for coatings, adhesives and synthetic fibers. 100% except a small amount

In addition to resin plastics, most plastics need to add other substances in addition to the main component resin.

2. Filler, also known as filler, can improve the strength and heat resistance of plastics and reduce costs. For example, adding wood flour to phenolic resin can significantly reduce costs,

It makes phenolic plastic one of the relatively cheap plastics, and significantly improves the mechanical strength. Fillers can be divided into organic filler and wood filler, rag, inorganic filler such as paper and

Kinds of textile fibers, such as glass fiber, diatomite, asbestos, carbon black, etc.

3. Plasticizer Plasticizer can improve the plasticity and softness of plastics, reduce brittleness and make plastics easy to process. Plasticizer is usually miscible, non-toxic, tasteless, high boiling

Point organic compound, light and heat stable, and usually used for phthalates. For example, when manufacturing PVC plastics, if more plasticizers are added, if

Soft polyvinyl chloride plastics can be obtained without adding or adding plasticizers.
