Blister packing: Plastic processing technology, the main principle is that after heating and softening the flat plastic hard sheet, vacuum is used to adsorb it on the surface of the mold, and it is formed after cooling, saving raw and auxiliary materials, light weight and convenient transportation.
Blow molding: The tubular plastic parison obtained by extruding nylon is placed in a split mold while it is still hot. After closing the mold, air is compressed in the parison to inflate the plastic parison and stick to the inner wall of the mold. mold to obtain various hollow products. The main products are: nylon casing film, bottle, jar, nylon tube, etc.
Injection molding: molding is mostly used for thermoplastics. It is similar to extrusion molding, the difference is that the molten plastic enters the closed mold through the nozzle, and the product is solidified and formed in the mold. More production of small boxes, daily necessities. Special-shaped parts, etc. It can also be used for hot plastic processing.
