1. Artificial edge
Large labor intensity, low efficiency, and low qualification rate.
2. Mechanical repair
There are mainly rinse, sand wheel grinding edges, and round -knife repair, which is suitable for specific products with low accuracy.
3. Three frozen edges
The principle of a dedicated frozen border repair machine is to use liquid nitrogen (LN2) to make the hair edges of the finished product become brittle at low temperature. Use a specific frozen particle (projectile) to hit the wool edge to quickly remove the wool edge. Frozen edges are high efficiency, low cost, and extensive applicable products, which have become the mainstream process standards.
