ZJK Industrial Co., Ltd. Triples Captive Screw Production Efficiency with New Semi-Automatic Equipment
Traditionally, the production of captive screws involves assembling multiple components and manual punching, leading to low efficiency and inconsistent quality. Captive screws are composed of screws, housings, and springs, and require specialized tooling to prevent parts from dislodging before stamping and assembly. Additionally, the stamping mechanism’s working pressure must be adjusted to accommodate products of varying specifications. These challenges contribute to high manufacturing complexity and cost, despite the strong market demand for such fasteners.
To address these issues, ZJK invested in research and development to design a semi-automatic assembly system. The new system incorporates a circular workbench with a divider and an adjustable stamping mechanism, allowing seamless integration into automated assembly lines without manual intervention.
With this new equipment now operational, the Company has significantly enhanced its existing automated assembly capabilities for combined parts and opened up new possibilities for subsequent assembly processes. According to the Company, the new system has increased captive screw production efficiency by over three times and reduced required labor by 50%, further strengthening ZJK’s competitive edge in the fastener sector.
