Quality:
1. Most production batches are testing by labs for chemical composition.
2. For any new supplier, we will compare its chemical test results with authoritative labs.
3. Tensile strength, elongation and hardness are also tested frequently. A standard sample rod is made along with each batch.
4. Ultrasound checking can also be done.
5. We are familiar with ASTM, SAE, MIL, BS standards
6. Data logging (paper trail) are strictly required from incoming material inspection throughout all major production steps (melt mix, casting, heat treatment, machining...) to ensure trackability.
7. We typically do a small batch production even after a sample is approved by customer. This is often necessary to ensure stability/ consistence of quality. PPAP reports can be provided.
