Q
Plastic is everywhere in our life, but do you really know the plastic? Open

Each plastic ware, there is a number at thebottom, it is a triangle with arrows, triangle there is a number. These Numbersrepresent the different plastic material. They have the most security products,can be repeatedly used, and some of the repeated use is likely to release toxicsubstances.

Q
PP plastic processing technology is what? Open

PP material is thermoplastic, non-crystalline, shrinkage rate, forming temperature range is wide, good liquidity, PP plastic usually suitable for blow molding, extrusion and injection molding.

Q
The characteristics of PE, main USES and the difference of each label Open

PE basic is divided into three categories, namely, high pressure low density polyethylene (LDPE), high density polyethylene (HDPE) and linear low density polyethylene (LLDPE). Film is its main processing products, followed by sheet and coating, hollow containers such as bottles, cans, barrels and other all kinds of injection molding and blow molding products, pipes and wire, cable insulation and sheath, etc.

Q
Plastic injection molding process is what kind of? Open

Injection molding is the use of injection molding machine (or injection machine) to thermoplastics melt under high pressure into a mold Canon of cooling and solidification get products. Plastic injection can also be used for thermosetting plastic and foam plastic forming. Injection molding is the advantage of production speed, high efficiency, operation can be automated, to forming of complex shape parts, especially suitable for mass production.
