FAQ
- How do you ensure perfect meshing with our pinion without vibration?
- We do a 100% Lead & Pitch Error Test and a factory tooth contact test to guarantee a contact area over 70% for smooth running.
- Can you match international material standards (ASTM/DIN)?
- Yes. We accurately match grades (e.g., ZG42Cr1Mo to ASTM A216 or DIN GS-34CrMo4) and provide a traceable EN 10204 3.1 Material Certificate.
- How do you guarantee the teeth won't break due to internal defects?
- Every gear undergoes 100% Volumetric UT & MT (Level 1/2) after rough machining to ensure the core of every single tooth is flawless.
- Delivery delay means huge penalties for us. How do you guarantee lead time?
- We are a 100% in-house facility (melting + casting + CNC machining). With zero outsourcing, we have absolute control over the production schedule.
- How do you protect the gear teeth from rust and damage during sea freight?
- Gears are coated with heavy anti-rust oil, vacuum-sealed in plastic, and rigidly fixed inside a custom heavy-duty steel-framed crate.
