Rigorous Quality Control & Fabric Testing Process | LEMP Sports Custom Bag Manufacturing

At LEMPSports, we understand that for global sports brands and importers, product reliability is paramount. A single batch of defective zippers or non-waterproof fabric can damage years of brand equity. That’s why our manufacturing protocol goes far beyond basic sewing.

1. Pre-Production Material & Printing Validation

Before cutting bulk fabrics, our QA lab tests every roll for tensile strength, colorfastness under UV exposure, and water-repellency standard. We also perform test prints (silk-screen, heat transfer, or embroidery) to ensure pristine logo crispness and adhesion longevity.

2. Multi-Stage In-Line Quality Inspections

During bulk assembly across our production lines in China and Myanmar, QA inspectors conduct random samplings at three crucial milestones:

• Early Stage: Verifying panel cuts, initial seam allowances, and component alignment.

• Middle Stage: Inspecting zipper stress points, webbing bartacks, and lining installation.

• Final Stage: Checking overall structure, thread trimming, dimensional accuracy, and clean finishing.

3. Ready for Global OEM/ODM Distribution

With 1,000+ skilled workers and an annual capacity exceeding 10 million units, LEMP Sports combines industrial scale with meticulous craft. Partner with us to bring your custom backpack or sports bag line to market with absolute confidence.
