Drawing review
Dimensions, holes, thickness, material, and assembly context are confirmed before production.
Quality approach
Quality control starts with the submitted drawing or sample and continues through material confirmation, conversion, and pre-dispatch inspection.
Dimensions, holes, thickness, material, and assembly context are confirmed before production.
Sourced foam and adhesive materials are supported by supplier-provided RoHS and REACH reports.
The production floor performs basic physical-performance checks against the confirmed requirement.
Finished profiles and packing are reviewed before dispatch against the order specification.
HAI HONG does not claim to issue material certifications. RoHS and REACH reports referenced by the company are supplied by upstream material providers.
Send your specification and our engineering team will confirm material, process, and feasibility for your custom foam or adhesive component.
