Injection molding machine parts including Injection parts, Clamping parts, Hydraulic parts, Electrical control parts and lubrication parts.
Plastic injection molding machine parts include injection units, clamping units, molds, cooling systems, control systems, and auxiliary equipment. These Plastic injection molding machine parts work together to achieve efficient transformation of plastics from pellets to finished products. This equipment is widely used in the production of plastic products with complex shapes and high precision requirements, and is an indispensable and important tool in modern manufacturing.
Injection molding machine is a complex equipment. It uses to manufacture plastic parts. It mainly composes of multiple components, each of which has a specific function. The following is a detailed introduction to the main parts and their functions.
5 main Injection Molding Machine Parts, as below:
- Injection part: melts the plastic material and injects it into the mold
- Mold clamping parts: hold molds in place, ensure injection in accurate molten plastics
- Hydraulic parts: power and control various critical movements
- Electronic control parts: set and monitor critical process parameters
- Lubrication parts: ensure smooth operation, reduce friction, and extend machine parts lifespan
Their functions are to heat the plastic raw material to a molten state;
Inject it into the mould through the injection device;
And form various shapes of plastic products after cooling and curing.

Injection molding machine parts: injection parts
The injection device is the core part of the injection molding machine. It is mainly composed of a screw and an injection nozzle.
Injection moulding machine components of injection parts
The screw is responsible for conveying the plastic raw material from the hopper to the injection nozzle and heating it to a molten state through a heating mechanism.
The injection nozzle is responsible for injecting the molten plastic into the mold.
The injection parts main function is responsible for melting and injecting plastic materials into the mold. The material barrel heats the plastic to a molten state through a heating element, and the screw rotates to push the molten plastic into the mold.
Injection molding machine parts: Mold clamping parts
The mold clamping device is used to keep the mold closed during the injection process to ensure that the plastic melt can fill the entire mold cavity. The mold clamping device usually includes components such as templates and tie rods, which need to withstand the high pressure generated during the injection process.
Injection molding machine components of mold clamping parts
The template: consists of the fixed platen and movable platen.
The fixed platen is the part of the machine used to mount the fixed mold;
The movable platen mounts the movable mold and moves to drive the mold separation when the mold opens.
The tie rods: It is four rods installed in the dead corners of the fixed template and removable template of the machine.
Its main function is to ensure that the injection molding machine has sufficient strength and rigidity and is responsible for the sliding template.
Hydraulic parts of Injection Molding Machine Parts
The hydraulic system provides power for the plastic machine and controls the actions of the injection device and the mold clamping device. The hydraulic system includes components such as oil cylinders and accumulators. The accumulator can store energy and release it quickly when needed to improve the response speed and stability of the system.
Injection molding machine components of hydraulic parts
Oil cylinders: to generate the necessary hydraulic pressure to drive the movement of the injection screw; accurately injecting the molten plastic into the mold.
The accumulators: can store energy and release it quickly when needed to improve the response speed and stability of the system.
Electrical control parts:
The electronic control system is responsible for the operation control of the entire injection moulding machine, including temperature control, pressure control, and time control. Modern machines are usually controlled by a PLC (Programmable Logic Controller) to achieve more precise operation and higher production efficiency.
Injection molding machine components of electrical control parts
PLC(Programmable Logic Controller) is the core control system of the machine.
PLC ensures the high precision of the injection molding process and the product quality by accurately controlling key process parameters. Such as temperature, pressure, injection speed, etc.
In addition, the design and manufacture of injection molding machines also involve aspects such as material selection, structural optimization, and fault prevention and maintenance. For example, the design of mold parts needs to take into account the strength and durability of the material to ensure long-term stable operation.
Lubrication parts
The machine’s moving parts need lubrication. Because the movement between two parts will be wear and tear.
Lubrication of injection molding machines is very important.
Reasonable lubrication strategies and regular maintenance can effectively improve the performance and lifespan of injection molding machines.
The barrel body can also reduce the occurrence rate of malfunctions.
Injection molding machine parts: key components materials
- Screw: as one of the key injection moulding machine parts. It usually uses nitrided steel (such as 38CrMoAl) surface nitriding treatment. Or bimetallic alloy (such as cobalt-based alloy) to improve wear resistance.
- Mold cylinder: one of main important plastic injection machine parts. With 35/45 steel seamless steel pipe commonly uses for the cylinder body. The carrier is gray cast iron or ductile iron. And the integrated casting process improves rigidity.
- Hydraulic seals: They usually make of rubber, polyurethane, PTFE (polytetrafluoroethylene) and other materials. These injection molding machine parts have good wear resistance, corrosion resistance and tear resistance.Nitrile rubber (NBR) or polyurethane (PU), temperature resistance must be above 120℃.
- Guide rail: This injection moulding machine parts using metal alloy steel treated with high-frequency quenching. The surface hardness HRC50-55, with graphene polymer repair technology to extend life.
