Problems solved by technology

The injection molding machine mainly includes parts such as feeding mechanism, barrel, screw and nozzle; the existing feeding mechanism is mostly a single feeding funnel, which cannot better filter out the iron chips in the plastic raw materials; now Some barrels will lose a lot of heat during the production process, resulting in a waste of energy; the existing screw needs to move as a whole during the injection process, resulting in high energy consumption and greater wear; the existing nozzle There will be salivation when the injection is completed, resulting in contamination of the melt and waste of materials
