Moreover, plastic manufacturers have imported varieties of models of machines to meet. In this article, we will learn more about the structure and operating principle of the machine.

What is a plastic injection molding machine?

Plastic injection molding machine, also known as glue press. An injection molding machine is a machine commonly used in the production line of plastic bottles and jars. Moreover, the machine’s main use is to fix the closed mold during the process of pushing the molten plastic by injection pressure into the mold core. 

At that time, the plastic will fill the mold cavity and open the mold when the plastic product has cooled.  Currently, there are many types of machines with all different designs and models. 

They are classified based on the following factors:

• According to the axis
• The Working principle of mold
• The Structure principle (hydraulic, electric)
• According to the size of the plastic injection machine

Depending on the type of plastic injection mold, design, and size of the product, the user will choose the appropriate machine. Currently, modern machines match many types of products. One machine can be common flexibly for many different types of products.

The general structure of plastic injection machine

The plastic injection machine consists of 2 main components: plastic injection part and mold clamp part.

Mold clamp part

This is an important part, including the movable mold clamp and the fixed mold clamp. In there:

The fixed mold clamp has the main task of clamping and keeping the mold fixed. As a result, the mold will always stay in the correct position thanks to the positioning ring on the mold and the positioning hole. 

The movable plastic injection mold clamp has the main function of clamping the movable side of the mold. This part will move in a direction parallel to the opening and closing direction of the mold during the injection molding cycle. 

At the same time, it arranges with a push-pull to help effectively impact the battery ejector plate when pushing the product out.

Conclusion

This is the component that uses heat to convert the plastic from a solid to a liquid form. Then, the liquid plastic part pushes into the mold set through the nozzle pressure system and the screw.

In addition, the structure of the machine will include some other parts: a cooling system, a support system, etc.

System of plastic injection machine

Currently, the system of the custom injection mold will be divided into 2: the basic system and the injection molding support system.

The basic system includes: 

• Clamping system
• Spray system
• Mold system
• Injection molding support system
• Control system

Injection molding support system includes:

• Machine body

• High-frequency press machine

Sort by size

• Large presses (100 tons and 150 tons, 200 tons, etc.)
• Mini injection machine (Mini plastic injection molding machine and manual mini plastic injection molding machine)

The operator operates a custom injection mold maker

A plastic custom injection mold has the same operating principle as an injection pump. First, the plastic will be put into the storage hopper. Then, they will be liquefied by the heating rod at the appropriate temperature. Next, the entire liquid plastic will move forward thanks to the screw. 

At the same time, the screw will move backward to create space for the plastic to flow into the front of the nozzle. Thanks to the thrust of the screw, the hot plastic will be molded. Finally, the cooling system cools the product before taking it out.

Uses of plastic injection machines

Plastic injection molding machines are used to create plastic products of various textures and shapes. They allow creating products with absolute precision compared to the design. In addition, you will make many products in a short time. 

For simple details, in 1 minute, you will create about a few dozen products. Product quality is uniform, with no condition, distortion, breakage, or deviation from your design.

Custom injection mold knocks out conventional packaging and bottle manufacturing methods. When using, one thing is sure: the aesthetic value of the product will be guaranteed. Moreover, it also helps to save significant costs for businesses, promoting strong development.

Installation and repair instructions for plastic injection machines

Usually, the machine will be quite large. Therefore, you should prepare a large space to place the machine. In addition to the size and weight factor, the installation of the machine is quite simple. Most of the time, you will only need a stable power source and a large enough space to place the machine.

As for custom injection mold operation, you will find it challenging to do this job if you do not have too much experience. Usually, there will be one user manual for customers when buying the machine. However, you should have a team of technical staff with experience in this field to facilitate the operation and maintenance of the machine.
