Vertical PVC Plastic Injection Molding Tester/Factory Injection Machine

Brief introduction:

LR-350ST injection molding machine is the main molding equipment to make plastic products of various shapes by thermoplastic or thermosetting plastics using plastic forming molds.Divided into vertical, horizontal, full – electric.The injection molding machine heats the plastic, applying high pressure to the molten plastic so that it is shot out and fills the mold cavity.
