Plastic barrel injection molding and rotational molding meth

Plastic barrel injection molding and rotational molding method introduced

 

Plastic bucket when in use is required for injection molding and rotational molding, but for this method is that we do not understand, let Xiaobian to introduce you to it!

     First, injection molding grade is generally a melt index of 5-10, with a toughness lower liquidity grade and has a high workability grade mobility, its use is generally thin-walled packaging daily necessities and food, toughness and durability food and paint cans and high resistance to environmental stress cracking applications. Then, this working method using the rotational molding material is generally crushed to a powder material to melt and flow during thermal cycling.

     Rotomolding applications is the use of high-performance chemical cross-linking grade unique properties, these grades in the first paragraph of the molding cycle, good liquidity, and then cross-linked to form its excellent resistance to environmental stress cracking resistance, toughness, wear resistance and weather resistance.
