Import Constant Force Torsion Memory Tension Spring — Buy in Bulk from Supplier in China

The Constant Force Torsion Memory Tension Spring from Taian Henson Metal Co., Ltd. is engineered to deliver consistent force output across dynamic motion cycles, making it suitable for precision mechanical systems. It is designed to maintain torque stability under repetitive loading, with a focus on durability in high-stress environments. The spring’s memory alloy properties allow it to return to its original shape after deformation, a critical feature for applications requiring long-term reliability.

Constructed from high-grade steel or nickel-titanium alloys, this spring resists fatigue and corrosion, which are common failure points in standard torsion springs. Typical industry grades include music wire (ASTM A228) or stainless steel (302/304) for general use, while memory alloys like Nitinol are used for temperature-sensitive applications. The material choice directly impacts the spring’s load capacity, with typical tensile strengths ranging from 1,200 MPa to 2,000 MPa depending on the alloy and heat treatment.

This spring type is primarily used in automotive components such as seatbelt retractors, aerospace actuation systems, and consumer electronics for hinges or counterbalance mechanisms. Buyers in these sectors prioritise consistent force delivery, often specifying load tolerances within ±5% of the nominal value. For bulk sourcing, confirm packaging standards (commonly plastic reels or wooden crates) and lead times, as these vary by supplier and order volume.

Taian Henson Metal Co., Ltd. is a China-based supplier specialising in precision metal components, including torsion springs and custom mechanical assemblies. The company operates with an imported supplier tier, indicating it sources materials or components internationally before processing or assembling products for export. Its profile reflects a focus on industrial buyers, with no additional verification signals such as response rate or average reply time currently available.

The supplier’s product range includes constant force springs designed for dynamic applications, catering to sectors like automotive and aerospace. While the listing does not specify certifications, buyers should confirm compliance with relevant standards such as ISO 9001 for quality management or industry-specific requirements like IATF 16949 for automotive. No details on production capacity, lead times, or minimum order quantities are provided, so direct enquiry is necessary to establish trade terms.
