Two-color injection molding machine refers to a machine that produces two plastic products of different colors or different materials after being plasticized by two different barrels of the same injection molding machine, and then injected through the same nozzle. The advent of two-color injection molding machines has increased the production efficiency of two-color plastic products, meeting the large demand for two-color plastic products on the market. The two-color injection molding machine has two types: injection screw parallel injection molding machine and injection screw vertical injection molding machine.
In injection molding machines, the use of screws is very large. The screw is a metal rod that can be rotated and has a groove in the barrel. It is a component for extrusion molding and conveying solid plastics, plasticized plastics and melts. The two types of two-color injection molding machine are mainly different from the placement of the injection screw. What is the difference between the two installation methods?
First, injection screw parallel injection molding machine
Injection screw parallel injection molding machine means that the screw of the injection molding machine is in parallel arrangement and can be operated independently or simultaneously, and this type of injection molding machine has two independent acting ejection mechanisms.
Second, injection screw vertical injection molding machine
Injection screw Vertical injection molding machine means that the screw of the injection molding machine is in the same plane and in a vertical arrangement. It can also operate independently or simultaneously, but this type of two-color injection molding machine has only one set of ejection mechanism.
Third, how to choose a two-color injection molding machine
Before choosing a two-color injection molding machine, first determine the conditions of the materials required, such as the design, size and weight of the mold; secondly, the type and quantity of the plastic used; and the shape and quality of the plastic. Only when the above conditions are clarified can the “prescription of the right medicine” be properly selected. It is worth noting that when choosing a two-color injection molding machine, it must be determined whether it has a fully automatic flanged pick-up system and a fully automated workflow, and at the same time have a certain grasp of the servo technology. Therefore, when choosing a two-color injection molding machine, you must do your homework in advance to select the right two-color injection molding machine.
