Quick answer for buyers
Bohua supports four casting routes — gravity, die, low-pressure, and sand — with CNC machining coordination, inspection planning, and export-ready delivery from Ningbo. Buyers should send drawings, alloy target, annual volume, and machining scope to get a process-route recommendation and manufacturing quote.
Buyer facts

Capabilities FAQ
What measurement and verification equipment do you have?
Bohua's confirmed equipment includes Oxford OES, Unicomp UNC-160 X-ray, Y.MU2000-D X-ray, Hexagon Global S CMM, NANO Metrology CMM, Vacuum hydrogen analyzer, Pressure-tightness testing workshop, WDW-100E tensile testing machine, JB-300B impact testing machine, Fatigue testing capability, YWX-750 salt spray testing chamber, Olympus GX51 metallographic microscope, HBE-3000A hardness tester, Mitutoyo SJ-210 surface roughness tester, German-brand 3D scanner. Inspection plans are defined according to customer and project requirements. Some characteristics may require 100% inspection, while others are controlled through an agreed sampling plan. Inspection equipment is calibrated annually.
Can you support automotive quality system and documentation requirements?
Bohua Casting operates under an NQA-certified IATF 16949 quality management system. ISO 9001 requirements are incorporated within the IATF 16949 system; Bohua does not currently hold a separate ISO 9001 certificate. ISO 14001 certification is under application. PPAP documentation can be provided up to Level 5 according to project requirements.
What is your quality control process?
Our quality workflow starts from incoming material and melt verification, continues through process control during casting and secondary operations, and ends with dimensional, visual, and application-specific quality review before shipment.
Do you have in-house secondary operations capability?
Yes. Bohua has in-house CNC finishing centers to complete critical datums, sealing faces, holes, and other precision features after casting.
What is your heat treatment capability?
We support heat-treatment routes such as T5 and T6 for suitable gravity-cast and low-pressure-cast aluminum alloys, depending on the part requirement and validation target.
Can you handle low-volume orders?
Yes. For prototypes, bridge quantities, or specialized geometries, Bohua can support lower-volume work through sand casting, selected gravity casting setups, and development runs with finishing operations.
