General Finished Product Manufacturing Standards
Appearance and Sewing Requirements: The overall appearance should be flat and clean, with even stitching and no obvious wrinkles. Key load-bearing areas require multiple reinforcements. Pocket edges should be neat, with individual reinforcement at the opening. Shoulder straps and other load-bearing areas should have even stress distribution to ensure comfortable use.
Hardware Requirements: All hardware must be treated for wear resistance and rust prevention to ensure long-term durability.
Structural Layout Requirements: The layout of inner and outer pockets should be reasonable and user-friendly. Professional tool bags should be tailored to the specific industry's needs and should include necessary safety warnings to ensure safe use.
Special Manufacturing Process for EVA Material Tool Bags
EVA tool bags are a common type of tool bag, and the manufacturing process and requirements are more clearly defined:
Lamination Process: First, the outer fabric and lining are laminated with the EVA material to obtain sheets of uniform size, preparing for subsequent cutting.
Cutting Process: Based on the actual material width required for the product, the laminated sheets are cut into smaller pieces of the corresponding size.
Pressure Molding Process: The product is formed according to a mold using hot or cold pressing. The product logo can be printed using hot pressing, pad printing, or heat transfer printing processes, supporting both single-color and multi-color production.
Finishing Process: After all auxiliary materials are prepared, the product is reinforced by sewing. Following inspection and finishing, it undergoes final QC inspection before being packaged and shipped. Failure to meet standards at any stage will affect the final product quality.
