The Introduction of Injection Moulding Machine

Injection moulding is a highly versatile manufacturing process used to produce a wide range of plastic parts and products. Central to this process is the injection moulding machine, which consists of three basic types. These machines play a crucial role in the production of plastic parts and can be found in various industries, from automotive to electronics and consumer goods.


Hydraulic Injection Moulding Machine

Hydraulic injection moulding machines are the oldest and most commonly used type of injection moulding machine. As the name suggests, they operate using hydraulic power to generate the necessary force to inject molten plastic into a mould cavity. These machines are known for their high production capacity and are capable of producing large and complex plastic parts. The hydraulic system allows precise control over the injection process, providing consistent results and high-quality parts.


Electric Injection Moulding Machine

Electric injection moulding machines are gaining popularity in recent years due to advancements in technology and growing demand for more energy-efficient and environmentally friendly options. These machines utilize electric motors to drive the plasticizing unit, clamping mechanism, and injection system. By eliminating the need for hydraulic power, electric injection moulding machines offer faster cycle times, higher precision, and reduced energy consumption. They are particularly suitable for applications that require high precision and clean operation, such as medical devices and electronics.


Hybrid Injection Moulding Machine

Hybrid injection moulding machines combine the best qualities of hydraulic and electric machines. They feature an electrically driven screw plasticizing unit and an electrically driven clamp unit, while the injection unit is powered by hydraulic pressure. This combination allows for improved energy efficiency, reduced noise levels, and increased precision. Hybrid machines are versatile and can be used for a wide range of applications. They are especially favored in the automotive industry, where they offer excellent precision and reduced cycle times for mass production.



In summary, injection moulding machines are essential in the plastic manufacturing industry. Hydraulic, electric, and hybrid machines provide different advantages and are suitable for various applications. Hydraulic machines offer high production capacity, electric machines provide efficiency and precision, while hybrid machines combine the best of both worlds. Understanding the three basic types of injection moulding machines can help manufacturers choose the most suitable option for their specific production needs to achieve optimal results.
