Metal Stamping Clip

The Metal Stamping Clip secures components through the elastic properties of the spring material. Stable springback is essential for maintaining consistent locking performance throughout the product's service life. SUS301 stainless steel and 65Mn spring steel are commonly selected because both materials retain their elasticity well after heat treatment. Beryllium copper is also available for applications requiring higher fatigue resistance or improved electrical conductivity.

Fatigue testing is carried out using dedicated in-house equipment. After 500,000 opening and closing cycles, permanent deformation remains below 0.02 mm, a level that is difficult to detect visually. Under typical operating conditions of around 100 cycles per day, this represents an expected service life of approximately 13 years. For products with higher durability requirements, designs supporting 800,000 or 1 million operating cycles can be developed.

The standard locking force is controlled between 40 N and 60 N to provide secure retention while maintaining comfortable operation. Each Metal Stamping Clip is verified with a push-pull force gauge to ensure consistent locking performance. Spring force and operating stroke can also be adjusted to match different installation requirements.

Bright nickel plating and black zinc coating are available for improved corrosion resistance and appearance. A standard R0.3 corner radius is applied to exposed edges to reduce the risk of scratches during assembly while helping protect mating plastic components from damage. Chamfer dimensions and surface color can be customized according to project requirements.

The interference fit between the clip and the mounting slot is typically controlled between 0.1 mm and 0.2 mm. This allows the clip to engage smoothly while providing clear locking feedback after installation. Tooling is adjusted during production to maintain consistent engagement and insertion force across each production batch.

To prevent surface damage during transportation, small clips are individually packaged before shipment. Standard samples are normally completed within 3–5 days, and customer feedback is reviewed within 24 hours to support timely project progress.
