Injection molding machine: a complicated shape can be a shape, size, accuracy, or the ability to metal inserts dense texture of plastic products with, is widely used in national defense, electronics, automotive, transportation, building materials, packaging, agriculture, education, health and all areas of daily life. The rapid development of the plastics industry today, both in the injection molding machine on the quantity or variety occupies an important position, its total production accounted for 20% of the plastic molding equipment --30%, thus becoming the fastest growing plastics machinery, production volume One of the largest models. Purpose injection molding machine: Injection molding machine structure has vertical and horizontal. Press to produce the products can be divided into common type and precision injection molding machine. An injection quantity 45-51000g; clamping force 200-36000kN; processing plastic materials thermosetting plastics, thermoplastics and rubber three. Ordinary plastic electrical control injection molding machine is still the dominant direction of development, its basic structure is almost no major changes, except continue to improve its level of control and automation, reduced energy consumption, manufacturers are developing to a combination of changes in the market direction of the series as a model injection molding machine configuration large, medium and small injection device, a combination of standard and combination, adds flexibility to expand the scope and improve economic efficiency.
