FAQ :

1. What materials do you use for die-casting and forging parts?

We primarily use high-grade gray iron (GG20, GG25, GG30, or custom grades) known for its excellent wear resistance, vibration damping, and machinability. Other materials (ductile iron, steel alloys) are available upon request.

2. What are the advantages of gray iron for mechanical parts?

• High strength-to-weight ratio

• Superior vibration absorption (ideal for engines and machinery)

• Good thermal conductivity

• Cost-effective for high-volume production

3. Can you produce custom designs?

• Tailored dimensions & tolerances

• Modified material compositions

• Special surface treatments (coating, plating, machining)

4. What tolerances can you achieve?

Standard: ISO 8062 CT6-CT8 (die-casting) / ±0.1–0.5mm (forging). Tighter tolerances are possible with secondary machining.

5. How do you ensure quality?

• ISO 9001-certified processes

• 100% inspection of critical dimensions

• Material testing (hardness, tensile strength)

• Pressure testing (for hydraulic/automotive parts)

6. What industries do you serve?

✅ Automotive (engine blocks, brake components)
✅ Industrial Machinery (gears, pump housings)
✅ Construction (brackets, heavy-duty fittings)
✅ Agriculture (transmission parts, tillage tools)

7. What’s your lead time?

• Standard parts: 4–6 weeks

• Custom projects: 6–8 weeks (depends on complexity)
  Expedited options available.
