Plastic Injection Moulding Machine

Plastic Injection Moulding Machine is to use the thermophysical properties of plastic to add material from the hopper to the barrel, metal the materials through the heating ring and screw of the barrel, and transport and compact them forward along the screw groove. The materials are gradually plasticized, melted and homogenized under the dual action of heating ring heating and screw shear. During the completion of plasticization, the rear screw injects the molten materila in the storage chamber into the mold cavity through the nozzle under the action of the piston thrust of the injection cylinder at high speed and high pressure.

Product Description

Injection molding is to use the thermophysical properties of plastic to add material from the hopper to the barrel, metal the materials through the heating ring and screw of the barrel, and transport and compact them forward along the screw groove. The materials are gradually plasticized, melted and homogenized under the dual action of heating ring heating and screw shear. During the completion of plasticization, the rear screw injects the molten materila in the storage chamber into the mold cavity through the nozzle under the action of the piston thrust of the injection cylinder at high speed and high pressure. After the molten material in the mold cavity is pressure maintained, cooled, solidified and shaped, the mold is opened under the action of the mold closing mechanism. The shaped products are ejected from the mold through the ejection device.

What are the types of plastic injection moulding machine?

According to the form of clamping parts and injection accessories, there are three types: horizontal, vertical and angular.

Horizontal plastic injection moulding machine: horizontal injection moulding machine is the most commonly used type. The utility model is characterized in that the center line of the injection assembly is concentric or consistent with the center line of the clamping assembly, and parallel to the installation ground. It has the advantage of low center of gravity, stable operation, convenient die installation, operation and maintenance, larger die opening and small occupied space height. But it covers a larger area.

Vertical plastic injection moulding machine: the axes of the injection device and the clamping device are arranged vertically to each other. According to the relative position between the center line of the injection assembly and disassembly of molds, easy automation and management of multiple automatic lines. The disadvantage s that the ejected products are not easy to fall off automatically and often need to be taken out manually or by other methods, so it is not easy to realize full automatic operation and large scale product injection. Machine height, inconvenient feeding and maintenance.

Angle plastic injection moulding machine: the axes of the injection device and the clamping device are arranged vertically to each other.

According to the relative position between the center line of the injection assembly and the installation base surface, there are horizontal , vertical types: horizontal plastic injection moulding machine, the injection assembly line is parallel to the base surface, and the center line of the clamping assembly is perpendicular to the base surface; Vertical plastic injection moulding machine, the centerline of the injection assembly is perpendicular to the base plane, and the centerline of the clamping assembly is parallel to the base plane. Angle has the advantages of both horizontal and vertical injection molding machines. It is especially suitable for molds with asymmetric geometry of side gate.
