A barrel injection mold is a type of injection mold used to create plastic parts by injecting molten plastic into a mold cavity. It consists of a hollow barrel that is heated and filled with molten plastic, and a reciprocating screw that is used to move the plastic through the barrel and into the mold.
The barrel of the injection mold is typically made of steel or aluminum, and is heated by either electrical heating elements or hot oil circulated through the barrel. The screw is used to both melt the plastic pellets inside the barrel and move the molten plastic through the barrel and into the mold.
Barrel injection molds are commonly used in the plastic industry to create a wide range of products, including automotive parts, household appliances, and consumer products. They can be used to create complex and intricate parts, as well as large and small parts. Barrel injection molds are known for their high production rates, precise tolerances and ability to handle a wide range of materials.
The process starts by feeding plastic pellets into the barrel of the injection molding machine. The barrel is then heated to melt the plastic and the screw is used to move the molten plastic through the barrel and into the mold. Once the mold is filled, it is cooled and the finished part is ejected from the mold. The process is then repeated to produce additional parts.
