Divided from the overall structure and working principle, the domestic blister packaging machines can generally be divided into three series: (1) Roller blister packaging machines, On, J, type 130 ser

ABS is not affected by water, inorganic salts, alkalis and various acids, but is soluble in ketones, aldehydes and chlorinated hydrocarbons, and will cause stress cracking when eroded by glacial aceti

ABS has good electrical insulation and is almost unaffected by temperature, humidity and frequency, and can be used in most environments.

The heat distortion temperature of ABS is 93~118℃, and the product can be increased by about 10℃ after annealing treatment. ABS can still show certain toughness at -40℃, and can be used in the tempera

It has excellent impact strength and can be used at extremely low temperatures; ABS has excellent wear resistance, good dimensional stability, and oil resistance, and can be used for bearings under mo

ABS is non-toxic and odorless, and its appearance is ivory translucent, or transparent granules or powder. The density is 1.08~1.18g/cm3, the shrinkage rate is 0.4%~0.9%, the elastic modulus is 0.2Gpa

Containers include: packaging containers, bulk storage drums/tanks, and collapsible containers. However, with the maturity of the blow molding process, there are more and more blow molding products fo

The most commonly used raw materials are polyethylene, polypropylene, polyvinyl chloride and thermoplastic polyester, etc., which are often used to form packaging containers for various liquids, such

Hollow blow molding is further divided into injection blow molding, extrusion blow molding and stretch blow molding. Injection blow molding is to first make plastic into a bottomed parison by injectio

The compressed air required to inflate the parison in the mold must be clean. Injection blow molding air pressure is 0.55 ~ 1MPa; extrusion blow molding pressure is 0.2l ~ 0.62MPa, and stretch blow mo

It was not until after 1979 that blow molding entered a stage of widespread use. At this stage, blow molding grade plastics include: polyolefins, engineering plastics and elastomers; the application o

Blow molding mainly refers to hollow blow molding (also known as blow molding), which is a method of inflating a hot-melt parison closed in a mold to form a hollow product by means of gas pressure, an
