EspañolPlastic injection molding is a popular and economical industrial process used to manufacture a variety of plastic consumer products. Plastic Injection Mold includes Plastic Container Mould, Chair Mould, Air Candy Mould, Basket Mould, Tray Mould, Bucket Mould, Washing Machine Mould, Kitchenware Mould, Garden Equipment Mould, Water Tank Mould, Toy Mould, Bottle Cap Mould, Pet Supplies Mould, Toilet Bowl Block mold, gear mold, etc. These products are mass-produced using molding machines of various sizes and various specific requirements.
In the plastic molding process, plastic resins are used in the form of pellets or pellets. The choice of plastic type depends on the type of product being manufactured, requirements and overall budget. Of the hundreds of plastics available, only a few are safe for consumer use. Some materials used in the plastic injection molding process include polystyrene, polycarbonate, polypropylene, polyethylene, polyamide, polyvinyl chloride, Teflon®, Delrin® and acrylic.
Plastic is not degradable and therefore not friendly to the environment. However, the plastic injection molding process plays an active role in reducing waste. The plastic used in this process can be reused as many times as needed.
Pour the plastic pellets or pellets into the hopper of the injection molding machine. The feed hopper is a large container that leads to the heating cylinder. In a heating cylinder, the pellets are heated at high temperatures until the plastic melts.
The plunger or screw then pushes the molten plastic forward through the nozzle into the parting mold. The mold is the opposite of the part to be made and can have one or more cavities to make more parts at the same time. Molds can be made from durable and expensive steel, or from more affordable, less durable aluminum or beryllium metal.
As with choosing the right type of plastic, choosing a mold metal depends on product, cost, and durability factors. Manufacturers typically use less expensive metal molds for prototyping and obtain more durable, precision-machined molds as production demands increase.
The molten plastic cools in the mold, hardens and takes on the shape of the mold. The mold is then opened and the part is ejected. Then it's either ready for packaging, or for any other secondary operations. The entire plastic injection molding process is completed in minutes and can be automated.
