Product Description

OEM Stainless Steel Industrial Usage Double Spiral Metal Torsion Spring



Torsion spring is a mechanical part that uses elasticity to work. Usually made of spring steel. It is used to control the movement of machine parts, mitigate the impact or vibration, store energy, measure the size of force, etc. Torsion Spring, namely Torsion Spring, is a complex design principle among all types of springs and the type change is quite lively, so the theory involved in the design is the most complicated.
When the spring twists, the material is in a tensile or shear state as mentioned in the torsion calculation, so the torsion Angle limit is ultimately caused by the failure of the material, which cannot be restored to its original state when plastic deformation occurs. Of course, the Von Mises stress calculated by the fourth strength theory is the maximum strength that the material can withstand. Combined with the length of the spring, the maximum allowable torsion Angle can be calculated.

Production line diameter: production wire diameter range 0.08mm-10.0mm Technical standard: according to customer requirements, the company to solve the customer's best as its own responsibility, but also to produce high precision spring specialty. RoHS compliant: Able to measure more than 76 chemicals and materials, plating thickness types of surface treatment: environmentally friendly (RoHS) nickel, zinc, plating, gold, silver, copper, black, electrophoresis, Dacro (suitable for long time outdoor use, can reach more than 90 hours of salt spray measurement
Torsional spring products using range: applicable to all kinds of toys, lighting, handbags, leather goods, luggage, gifts, handicrafts, stationery, electronics, electrical appliances, cameras, precision equipment, all kinds of traffic tools, metal plastic, electronic said, remote control, stroller, bicycles, washing machines, vacuum cleaners, lamps and lanterns, automobiles, furniture, toys, switch, socket, water heater, calculators, watches, Igniter, mouse, motor, mobile phone, medallion, fan, video DVD...
