What are the common problems in leather processing?

Leather processing is a complex process, and it often encounters some problems and challenges. The following are some common leather processing problems:

1. Leather quality: Leather is the main raw material for making leather products. If the quality of leather is not good, it may affect the quality and appearance of the whole product. Common leather quality problems include leather surface defects, uneven color and inconsistent thickness.

2. Size error: Leather products usually need accurate size and proportion, but in the process of processing, due to the flexibility of materials, inaccurate manual operation and other reasons, size error may be caused. These errors may affect the assembly and appearance of products.

3. Sewing problems: Leather products usually need sewing, but there may be problems such as wire knotting, thread jumping and wire breakage during sewing. These problems may lead to weak or unsightly sewing.

4. Corner treatment: The corner treatment of leather products is a key link. If it is not handled well, it may lead to problems such as uneven edges and rough edges. These problems will affect the overall texture and appearance of the product.

5. Product assembly: Leather products usually need to be assembled with multiple parts, but there may be problems such as mismatch and looseness during the assembly process. These problems may lead to the decline of product stability and durability.
