Automatic Buckle Belt
The belt body is top grain leather or high-quality PU. On the back we laminate a high-strength nylon toothed strip. The strip is 16 mm wide with 3 mm tooth pitch. Total teeth are 40–50, giving 12–15 cm adjustment range. Lamination is by high-frequency hot press (180°C, 5 kg/cm², 15 sec). Peel strength ≥8 N/cm. The buckle body is zinc alloy die-cast with a stainless steel locking spring and release lever.
No Holes, Millimeter Precision Adjustment
Our factory has a toothed strip lamination line. We use high-frequency hot press at 180°C, 5 kg pressure for 15 seconds. Our workers assemble stainless steel locking springs. The springs are vacuum heat-treated to HRC 48-52. Many medical rehabilitation brands work with us. The automatic buckle belt has no holes. You insert the belt body into the buckle and it locks automatically. You can adjust it to any tightness, millimeter by millimeter. An elderly customer said his hands are weak. He used to struggle with normal belts. Now he just pushes in.

Comfortable for Elderly and Patients
We offer many buckle shapes: square, curved, streamlined. Surfaces can be brushed, polished, or matte. One Japanese rehabilitation belt customer chose a curved matte buckle. It did not look like a medical device. Elderly users felt happy.
