Application
Variable force springs and variable torsion springs can be customized for various elastic curve changes according to specific applications,such as automotive seat belt,store shelf propelling device,pen-type drug syringe (insulin),cordless curtains.
 
The spring maintains a constant force to keep the drug flow constant, avoiding the patient's discomfort during injection. The elastic force at the end of the stroke is increased to ensure that no drug remains in the drug.When there are many goods, more force is needed to push the goods forward smoothly. When goods are gradually reduced, the force needs to be relatively reduced to avoid excessive force from crushing the goods.

Notice:
Because this type of spring is a non-standard product, the same shape has different sizes. QianYe has specialized in research and development and production of constant force springs for 20 years, and can customize constant force springs with a thickness of 0.075mm-0.85mm and a width of 4mm-50mm.You can also provide drawings or data (the thickness of the spring, width, working length, inner diameter, outer diameter), and the customer service staff can provide you with a quotation and customized cycle. Welcome to consult.
