The Wire Elongation Tester is specially designed for determining the elongation performance of metallic wire materials including copper wire, aluminum wire, copper-clad aluminum wire, aluminum-magnesium alloy wire and steel wire. The equipment is widely used by wire and cable manufacturers, conductor producers, quality inspection laboratories and certification testing organizations to evaluate the ductility and mechanical properties of conductive materials.

The machine adopts a precision mechanical transmission system consisting of a high-efficiency circulating lead screw and constant-speed motor. During testing, the movable clamp travels at a constant speed, applying a stable tensile force to the specimen until fracture occurs. The elongation percentage is automatically calculated and displayed, providing a fast and reliable method for wire quality assessment and compliance verification.

Dongguan Huakai Testing Equipment Technology Co., Ltd. is a professional manufacturer specializing in reliability and environmental testing equipment, with over a decade of industry experience. Unlike trading companies or OEM resellers, we are a vertically integrated manufacturer - owning our R&D, production, and quality control under one roof.
Every Huakai product is designed, engineered, and manufactured entirely in-house, giving us full control over precision, lead times, and customization depth that most suppliers simply cannot match.
Self-Developed, Not Sourced Our in-house engineering team holds multiple patents. We develop our own control systems, thermal management modules, and test software - not dependent on third-party core components that limit flexibility.
Fast Delivery Without Compromising Accuracy Standard models ship in as little as 7--15 business days. Our streamlined manufacturing process - not shortcuts - makes this possible.
Customization That Actually Goes Deep When clients require non-standard chamber sizes, unique temperature profiles, or integration with their existing data acquisition systems, we engineer a real solution - not just a relabeled catalogue product.
Global Compliance Built In All products are CE certified and comply with IEC, ASTM, MIL-STD, and GB standards. Our chambers have helped clients pass certifications across consumer electronics, EV batteries, automotive components, aerospace, and medical devices.
After-Sales You Can Rely On Factory engineers - not third-party agents - handle all technical support. Spare parts are stocked and dispatched within 24 hours. Remote diagnostics available for international clients.
