Capping machine:The hand-held electric capping machine is easy to carry around and can be conveniently used to tighten or loosen various bottle caps. The adjustable clutch can effectively avoid damage to the bottle cap and reduce the wear of the inner plug. Once the cap is tightened, the chuck autom

The chemical name of PET is polyethylene terephthalate, also known as polyester. At present, GF-PET is the most used by customers, mainly for preforms. PET has better rheology in the molten state, and the pressure has a greater effect on viscosity than temperature. Therefore, the pressure is mainly

1. Stainless steel Cr13: high hardness, strong corrosion resistance, hardness is HRC48-502. Aluminum: good cooling3. P20 mold steel: P20 steel is suitable for making plastic molds and die-casting mold materials for low melting point metals. This steel has good machinability and mirror grinding perfo

In order to make the metal workpiece have the required mechanical properties, physical properties and chemical properties, in addition to the reasonable selection of materials and various forming processes, heat treatment processes are often indispensable. Steel is the most widely used material in t

When the molten plastic parison falls on the open mold, the electrostatic charge will cause the following problems:1. When there is more than one parison on each mold, the static charge always has the same polarity. This way the parisons will repel each other. In this case, it is usually impossible

The screw speed directly affects the output of the blow molding machine and the quality of the product parison, and its value is determined by the size and shape of the screw and the extruded product, and the type of raw materials. Increasing the speed of the screw can significantly increase the out
