What are the details of the blow molding process?

Dongguan blow molding processing mold manufacturing mainly includes a die with a variable cavity composed of a die combination substrate, a die component and a die combination card, and a punch combined substrate, a punch component, and a punch combined card A convex die with a variable core composed of a cavity cut-off component and a side-cut combination plate. Coordinated change of mold convex, concave mold and auxiliary molding system. Plastic mold manufacturing can process a series of plastic parts of different shapes and sizes.

 

In order to improve the performance of plastics, various auxiliary materials such as fillers, plasticizers, lubricants, stabilizers, colorants, etc. must be added to the polymer in order to become good-performance plastics.

 

1. Synthetic resin is the most important component of plastic, and its content in plastic is generally 40% to 100%. Because of the large content, and the nature of the resin often determines the nature of plastic, people often think of resin as a synonym for plastic. For example, polyvinyl chloride resin is mixed with polyvinyl chloride plastic, phenolic resin is mixed with phenolic plastic. In fact, resin and plastic are two different concepts. Resin is an unprocessed virgin polymer that is not only used to make plastics, but also a raw material for coatings, adhesives, and synthetic fibers. In addition to a very small proportion of plastics containing 100% resin, most plastics, in addition to the main component resin, need to add other substances.

 

2, filler is also called filler, it can improve the strength and heat resistance of plastics, and reduce costs. For example, adding wood powder to phenolic resin can greatly reduce the cost, making phenolic plastic one of the cheapest plastics, and at the same time, it can significantly improve the mechanical strength. Fillers can be divided into organic fillers and inorganic fillers, the former such as wood flour, rags, paper and various fabric fibers, the latter such as glass fiber, diatomaceous earth, asbestos, carbon black and so on. There are many factors that can affect product quality during the blow molding process in Dongguan. If you do not pay attention, it may affect the quality of the product, but if these factors can be controlled, a production result that meets the product specifications and requirements will be formed. Therefore, the details are particularly important.
