Mould Hydraulic Cylinder

A mould hydraulic cylinder, also known as an injection moulding cylinder, is a specialized hydraulic cylinder designed for use in injection moulding machines. These cylinders play a critical role in the injection moulding process, where molten material is injected into a mould cavity to produce plastic or metal components.

Here are key features and considerations regarding mould hydraulic cylinders:

Purpose in Injection moulding:

Mould hydraulic cylinders are integral components in injection moulding machines. They provide the force necessary to clamp the mould halves together and to actuate the injection process.

Clamping Force:

One of the primary functions of a mould hydraulic cylinder is to generate clamping force. This force holds the mould closed during the injection and cooling phases, ensuring the precision and quality of the moulded parts.

Injection Movement:

Mould hydraulic cylinders are responsible for the movement of the injection unit, which injects molten material into the mould cavity. The cylinder's precise control is crucial for accurate injection and moulding.

Compact Design:

Mould hydraulic cylinders are often designed to be compact, fitting within the structure of the injection moulding machine. This ensures efficient use of space within the machine.

High Precision:

Precision is critical in injection moulding processes. mould hydraulic cylinders are engineered for high precision in both clamping and injection movements to achieve consistent and accurate moulding.

Hydraulic Pressure and Flow Control:

Mould hydraulic cylinders utilize hydraulic pressure and flow control systems to regulate the force applied during clamping and the speed of injection. This control is essential for adapting to different mould and material requirements.

Parallelism and Alignment:

Maintaining parallelism and proper alignment of the mould halves is crucial for producing high-quality moulded parts. mould hydraulic cylinders play a key role in achieving and maintaining these parameters.

Materials and Coatings:

Materials with high strength and wear resistance, such as steel or alloys, are commonly used for mould hydraulic cylinders. Some components may also have specialized coatings to enhance durability and reduce friction.

Temperature Control:

In some injection moulding applications, mould hydraulic cylinders may be designed to operate in environments with elevated temperatures. Specialized seals and materials may be used to ensure performance under these conditions.

Integrated Safety Features:

Mould hydraulic cylinders often include safety features, such as pressure relief valves, to prevent overloading and ensure safe operation. Safety is critical in injection moulding processes to protect both equipment and personnel.

Quick Response Time:

Mould hydraulic cylinders require quick response times to achieve efficient and high-speed injection moulding cycles. Rapid actuation is crucial for optimizing production output.


Regular maintenance, including checking for leaks, inspecting seals, and ensuring proper lubrication, is essential for the longevity and performance of mould hydraulic cylinders.

Why Choose Mould Hydraulic Cylinder?

Mould hydraulic cylinders are vital components in injection moulding machines, playing a key role in the precision and efficiency of the injection moulding process. Their design and functionality are tailored to the specific requirements of injection moulding applications, contributing to the production of high-quality moulded parts.
