FAQ
Q: What is your core competency as a transmission housing supplier?
A: We specialize in the end-to-end engineering, manufacturing, and supply of high-precision transmission housings (gearbox casings). Our expertise lies in translating OEM design specifications into durable, dimensionally accurate, and cost-effective cast and machined components.
Q: How do you ensure quality and consistency?
A: Advanced Process Control: Real-time monitoring of casting parameters (temperature, pressure, cycle time).
Comprehensive Inspection: Utilization of CMM (Coordinate Measuring Machine), optical scanners, and automated vision systems to verify dimensional accuracy against CAD models.
Material & Testing: In-house metallurgical lab for chemical analysis and mechanical testing (tensile strength, porosity checks, leak testing).
Certifications: Our company are ISO 9001 and IATF 16949 certified, adhering to strict APQP (Advanced Product Quality Planning) and PPAP (Production Part Approval Process) protocols.
Q: Can you support us from the design phase?
A: Absolutely. We offer Design for Manufacturability and Design for Castability services. Early collaboration is key. Our engineers can analyze your design to optimize wall thickness, rib placement, and draft angles to minimize weight, reduce machining, improve structural integrity, and prevent casting defects, ultimately saving time and cost.
Q: Do you offer sub-assembly or value-added services?
A: Precision Machining: Full machining of all bores, faces, and threaded holes.
Sub-Assembly: Pressing-in of bearings, bushings, seals, and studs.
Cleaning & Coating: Application of protective paints, powders, or anti-corrosion treatments.
Leak Testing: 100% pressure decay or flow-based leak testing before shipment.
