Embodiment 1
[0018] A manufacturing process of a mobile phone protective cover. First, at 180°C, a synthetic resin of hard rubber material ABS with a proportion of 30% is backlogged, and then the flake resin is injected into the mobile phone cover mold to form the inner hard shell of the mobile phone cover; secondly , At 150°C, accumulate 70% of the synthetic resin of the soft rubber material TPR, and then inject the sheet-shaped resin into the mold, and release the mold to form the outer soft shell of the mobile phone case, and finally the finished product.
Embodiment 2
[0020] At 350°C, accumulate 90% of the synthetic resin of the hard rubber material PP, and then inject the flake resin into the mobile phone case mold to form the inner hard shell of the mobile phone case; secondly, accumulate 10% of the soft rubber at 260°C The material is TPU synthetic resin, and then the flake resin is injected into the mold, and the mold is removed to form the outer soft shell of the mobile phone case, and the final product is finished.
Embodiment 3
[0022] At 250°C, backlog the synthetic resin of the blend of hard rubber material ABS and PC with a proportion of 43%, and then inject the flake resin into the mobile phone case mold to form the inner hard shell of the mobile phone case; secondly, backlog at 200°C The synthetic resin of the soft rubber material PU with a proportion of 57% is injected into the mold to form the outer soft shell of the mobile phone case, and the final product is finished.
