Design & Development Process
Step 07Final Sample Approval & Quality Assurance
The final sample is not a formality — it's the last line of deference before mass production begins. Every unit in every future batch will be held to the standard set here.
Physical Testing Before Anything Ships
Every pre-production sample goes through the same inspection protocol — no exceptions, no shortcuts. Here's what we test:
Dimensional measurement & tolerance verification
All critical dimensions checked against approved engineering drawings with calibrated instruments.
Structural & functional testing
Locking stability, pin movement, and operating smoothness validated under repeated use conditions.
Tensile strength testing
Pull-force and load resistance tested to specifications based on end-use application requirements.
Durability testing
Cycle testing for repeated open-close operation and long-term mechanical reliability.
Compatibility testing
Physical fit confirmed with specified belt widths, webbing types, and accessory components.
Every inspection item is documented against our internal SOP — so the standard that approves this sample is the same standard that governs every production batch.
Nothing Ships Until This List Is Complete
Every item on this checklist is confirmed with you — not just internally — before the sample is delivered and production is authorised:
Dimensions
Specifications, proportions, and tolerances verified against approved drawings.
Manufacturing Quality
Die casting integrity, parting line quality, and polishing refinement evaluated against master sample.
Color & Finishing
Plating color consistency, hairline direction, and surface texture confirmed under standardised lighting conditions.
Functional Performance
Mechanism reliability and real-world usability validated under actual use conditions.
Packaging Confirmation
Protection method, inner packaging material, and labelling requirements confirmed before production packaging is finalised.
