Polyamide Pneumatic Actuators' Advantage

Common pneumatic actuators are also called cylinders. They are generally made of aluminum alloy or steel and are driven by air source. However, the compressed air itself contains water. In order to achieve the inner wall resistance to water corrosion, various anti-corrosion treatments are required. Ensure that it will not be corroded by water during long-term work. And in order to resist environmental corrosion, the outer part of the pneumatic actuator also needs to be electroplated or painted. The process is complicated and not environmentally friendly. Moreover, the overall manufacturing cost is high and the product is heavy.

In the environment of environmental protection and energy shortage, the use of plastic instead of steel is driven by the situation. Plastic itself has many advantages, such as good processing performance, light weight, high specific strength, low thermal conductivity, good chemical stability, good electrical insulation, etc. In particular, most products can be formed at one time without further processing. The process is simple and the manufacturing process is pollution-free.

Commonly used plastic pneumatic actuators on the market include PP or PA, and PA can achieve the same strength as aluminum alloy through modification.
