Detailed introduction:

　　 Industrial cylinders

　　Pneumatic actuators that convert the pressure energy of compressed gas into mechanical energy in pneumatic transmission. Cylinders are of two types: reciprocating linear motion and reciprocating swing (see figure). Reciprocating linear motion cylinders can be divided into four types: single-acting cylinders, double-acting cylinders, diaphragm cylinders, and impact cylinders.

　　① Single-acting cylinder: Only one end has a piston rod. Air is supplied from one side of the piston to generate air pressure, which pushes the piston to extend. It returns by spring or its own weight.

　　② Double-acting cylinder: Air is supplied alternately from both sides of the piston to output force in one or two directions.

　　③ Diaphragm cylinder: A diaphragm replaces the piston, outputting force in only one direction, and returning to its original position with a spring. It has good sealing performance but a short stroke.

　　④ Impact cylinder: This is a new type of component. It converts the pressure energy of compressed gas into the kinetic energy of high-speed (10～20 m/s) piston movement to do work.

　　⑤ Rodless cylinder: A general term for cylinders without piston rods. There are two main categories: magnetic cylinders and cable cylinders.

　　Reciprocating swing cylinders are called swing cylinders. They are divided into two chambers by a vane. Air is supplied alternately to the two chambers, and the output shaft swings. The swing angle is less than 280°. In addition, there are rotary cylinders, gas-liquid damping cylinders, and stepping cylinders.

　　Jiangsu Kuna New Energy Co., Ltd. was established on July 24, 2018. The company is located west of Provincial Highway 326 in Xiangshui County Industrial Economic Zone, Yancheng City, Jiangsu Province. It has a registered capital of 166.67 million yuan, covers an area of 345 mu, and has a building area of 200,000 square meters. The total planned investment of the project is 600 million yuan. The first phase will start the construction of 75,000 square meters of factory buildings with a planned total investment of 350 million yuan. It mainly engages in the research, application, and production of special performance aluminum alloy materials such as automotive lightweighting and precision profiles.
