Injection molding is a manufacturing process widely used in the production of plastic products. The basic principle is to heat thermoplastic or thermosetting plastic particles to a molten state, and then inject them into the mold cavity by high pressure. After cooling and solidification, a plastic product consistent with the mold cavity is formed. The plastic particles are heated to a molten state in the barrel of the injection molding machine, and the screw rotates to push the molten plastic forward to make it evenly plasticized. The molten plastic is injected into the mold cavity through the nozzle under high pressure to fill the entire cavity space. The plastic cools and solidifies in the mold, maintaining the shape of the mold cavity. The mold opens, and the ejector mechanism ejects the molded part from the mold to complete a molding cycle.
The injection molding machine is the core equipment of injection molding, which is mainly composed of an injection device, a clamping device, a hydraulic system and a control system. The selection of the injection molding machine needs to be comprehensively considered based on factors such as product size, material properties, and production volume. Our company currently has 15 plastic injection molding machines ranging from 100g to 3500g, which can meet the diversified production needs from small precision parts to large and complex parts.
The mold is a key tool for injection molding, and its design directly affects the quality, production efficiency and cost of the product. The mold is usually composed of a mold cavity, a mold core, an ejection mechanism, a cooling system and other parts. Our company is equipped with more than 20 mold manufacturing equipment such as machining centers, which can independently design and manufacture high-precision molds to ensure the high quality and consistency of the products.
Including dryers, mixers, mold temperature controllers, manipulators, etc., which are used to assist the injection molding process and improve production efficiency and product quality. Our company also has more than 20 testing equipment and other auxiliary equipment to ensure that every link from raw materials to finished products is strictly quality controlled.
Polyethylene (PE), polypropylene (PP), polystyrene (PS), etc. are widely used in daily necessities, packaging materials and other fields. Polyamide (PA), polycarbonate (PC), polyoxymethylene (POM), etc. have high mechanical strength, heat resistance and wear resistance, and are suitable for automotive, electronics, machinery and other fields. Polyetheretherketone (PEEK), polytetrafluoroethylene (PTFE), etc., have excellent high temperature resistance, corrosion resistance, insulation and other properties, and are suitable for high-end fields such as aerospace and medical.
Injection molding technology is widely used in various industries to produce automotive interior parts, exterior parts, functional parts, such as dashboards, bumpers, door handles, etc. It is used to produce housings, connectors, switches, etc., such as mobile phone cases, computer cases, sockets, etc. It is used to produce medical equipment, consumables, such as syringes, infusion sets, surgical instruments, etc. It is used to produce household items, kitchen utensils, toys, etc., such as plastic cups, tableware, toy cars, etc.
