2. Types of Injection Machines

There are three main types of injection machines: hydraulic, electric, and hybrid injection machines.

Hydraulic Injection Machines:
Hydraulic injection machines use hydraulic pressure to operate the injection unit, clamping unit, and ejector unit. They are the most commonly used type of injection machine due to their low cost and ability to handle high-pressure applications.

Electric Injection Machines:
Electric injection machines use electric motors to operate the injection unit, clamping unit, and ejector unit. They are known for their precision, speed, and energy efficiency. They are also ideal for cleanroom applications because they do not produce oil or hydraulic fluid.

Hybrid Injection Machines:
Hybrid injection machines combine the best of both hydraulic and electric injection machines. They use a combination of hydraulic and electric components to optimize energy efficiency and precision.

3. Working Mechanisms of Injection Machines

Injection Unit:
The injection unit is responsible for melting and injecting the plastic material into the mold. The plastic material is fed into the injection unit through a hopper, where it is heated and melted. The melted plastic is then injected into the mold through a nozzle and sprue bushing.

Clamping Unit:
The clamping unit is responsible for holding the mold closed while the plastic material is injected. The clamping force required depends on the size and complexity of the mold and the plastic material being used. The clamping unit consists of a stationary platen and a moving platen, which are operated by hydraulic or electric motors.

Ejector Unit:
The ejector unit is responsible for removing the finished product from the mold. The ejector pins push the finished product out of the mold and into a collection bin.
