1. Introduction: Why Pre-production Sample Validation Matters
For global buyers of custom cemented carbide parts, defects found after mass production will cause huge losses and delayed delivery. Pre-production sample validation confirms dimensions, material performance and surface quality before starting bulk manufacturing, lowering project risks for both sides.
2. Step 1: Drawing Review & Sample Machining
Our engineering team reviews your drawing, tolerance and material requirements first. Then we produce pre-production carbide samples following the same production process used for mass orders, instead of simplified trial machining, to simulate real batch quality.
3. Step 2: Full Physical Inspection of Carbide Samples
- Dimension & tolerance measurement with precision tools
- Visual check for surface defects: cracks, chipping, scratches
- Hardness test and material property verification
- Surface finish inspection
Any non-conformity will be corrected and remade before sending samples to customers.
4. Step 3: Sample Test Report & Client Confirmation
We attach an inspection report with sample shipment. Once you approve the sample, we lock the production standard for mass production. Any adjustment requested by you will be updated into our production document before bulk run.
5. Sample Validation Checklist Table
| Check Item | Description | Remark |
|---|---|---|
| Drawing Matching | Dimensions, tolerance, shape | 100% compare with your CAD drawing |
| Material Performance | Hardness, density | Match selected carbide grade |
| Surface Quality | No crack, chipping or scratch | Visual & microscope inspection if needed |
| Inspection Document | Sample test certificate | Provided for customer approval |
6. FAQ for Carbide Pre-production Samples
Q1: How long does carbide sample validation take?
Sample lead time depends on part complexity, we will confirm timeline after drawing review.
Q2: Can I get samples for testing before bulk order?
Yes, we support pre-production samples for quality verification before mass production.
Q3: Will mass production be identical to approved samples?
We follow the exact same process and specs of approved samples for bulk production.
