Production Description:

Extension spring (also named tension spring and helical tension spring) is a helical spring to bear axial tension. It usually takes circular section material to creat equal pitch, thus the cross section is always round. In the absence of load, there is no gap between every circle of the extension spring.

They can be widely used in many occasions, for eg, production, experiment, research, maintenance,etc. Extension springs occupy very important position in the global market and are applied widely in the fields of National Defense, Marine, Computer, Electronics, Automobile, Mold, Medicine, Biochemistry, Aerospace, Railway, Nuclear Power, Wind Power, Thermal Power, Construction Machinery, Mining Machinery, Elevator, etc.

Application scope

  Electronic products, Washing machine, Vacuum cleaners, lights, cars, furniture, toys, switch, sockets, water heaters, calculators, watches, ignition, mouse, motor, mobile phone, lamp, fan, DVD, etc.
Brief description 1,longer life expectancy; 2, stronger elasticity; 3. better quality; 4. reasonable price. We are a 4S type manfacturer, offering technology development, spring design, producing and sales service. With advantage of producing high precision spring, we take the aim of solving problem for our clients.
Wire dia Wire diameter range: 0.08mm4.5mm
Tech standard As per clients' requests.
Surface treatment Nickel plating, zinc plating, electroplating, gold plating, silver plating, copper plating, black, electrophoresis,etc.adapt to prolonged outdoor use, and can stand salt spray test of more than 90 hours
Product line Our CNC computer spring machines, specially NO CAM NO ROCKER ARM design, are independently controlled by many group servo motor. Its adjust speed is 50% more quickly than traditional cam machine. In brief, its advantage is in
rapid produce speed, accurate positioning, and stable operation. To high difficulty and multi-folding spring, it can realize one-time molding, no need extra procession.
Also we have compression spring machine from TAIWAN, which can realize 100% inspection to spring on producing compression spring.
