Power springs are made from flat strip materials, typically produced by flattening steel wire or using high-carbon steel strips and high-strength stainless steel strips.
They are usually formed into a spiral (volute) shape, with the outer end fixed to a housing and an inner hook connected to the shaft. By rotating the shaft or housing, the power spring can be wound or unwound, generating the required torque.
Teng Yao Hardware Industrial Co., Ltd. is a professional manufacturer of power springs.

Non-magnetic constant force springs are commonly used in wire harnesses. Their appearance and characteristics are similar to standard constant force springs, but due to their non-magnetic properties, they are ideal for bundling electrical wires, as magnetic components may interfere with current flow.
Teng Yao Hardware Industrial Co., Ltd. is a professional manufacturer of non-magnetic springs, providing reliable and customized solutions for your specific applications.

We have a basic existing size specification table for you to provide the ideas you need. Please reply by email after providing the form and we will discuss further with you as soon as possible.

Yes, you can adjust the tension parameters you need by modifying the length, number of turns and other parameters within the allowed range.

Before the company starts the process of mass production of springs, it will first make and provide a few samples for customers to test, and try its best to make it achieve the results you want before proceeding to the next step of discussion.

Teng Yao Hardware Industrial Co., Ltd. specializes in customized constant torque springs, providing tailored solutions to meet your specific needs.
A constant torque spring is typically mounted on a storage drum, with its outer end attached in reverse to an output drum. When the output drum is rotated, the spring unwinds in the opposite direction, generating a constant torque on the output drum. Once the external force is removed, the spring rewinds from the output drum back onto the storage drum, returning to its natural state.

Providing drawings is more conducive to a more intuitive and efficient understanding of the product. We will provide a small number of samples. If there are any problems during the design process, we will inform you and propose solutions as soon as possible.

Make an actual judgment based on the required spring size. Due to the operating performance of the machine, it is a little difficult to make a decision if the quantity is too small.

Spring specifications and sizes vary, and the production time required is similar, depending on the actual situation.

Yes, we will choose the freight forwarding company to contact based on the situation of both parties, and it has ISO certification.
