Injection molding and blow molding refer to the different production processes of products

Injection molding is generally used to make relatively thick products, such as bottle caps, etc. Blow molding is the use of gas, such as bottles.

Injection molding because the product is thicker, the relative requirements are lower, blow molding is different, because the product is thinner, more transparent, and the slight shortcomings are obvious. Therefore, the requirements are high, and there are some requirements for the toughness and tensile properties of raw materials. Injection molding is less demanding.

The viscosity of blow molding must be high, injection molding is high pressure, blow molding is low pressure and then directly look at the soluble fat can also be seen, 3 soluble fat about the material is blow molding, blow molding material can be used for injection molding, the fluidity is just a little bit, but the injection grade material is used for blow molding is not good, injection grade material is generally dissolved fat in more than 10 fluidity.
