Quick answer for buyers
Bohua supports gravity casting and high-pressure die casting with CNC machining coordination, inspection planning and export delivery from Ningbo. Two low-pressure machines are in trial production. Bohua does not offer sand casting. Send drawings, alloy, annual volume and machining scope for a project review.
Buyer facts
| Location | Ningbo, Zhejiang, China |
|---|---|
| Process fit | Gravity and die casting are reviewed against geometry, alloy, tooling and inspection requirements. Low-pressure casting is in trial production and needs project-specific validation; sand casting is outside Bohua scope. |
| Size review | Gravity castings up to Approximately 2 m, subject to drawing review; HPDC castings up to Approximately 0.5 m, subject to drawing review. Other routes are confirmed from drawing and handling requirements. |
| Quality evidence | 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. PPAP documentation can be provided up to Level 5 according to project requirements. |
| Export execution | Available trade terms include EXW, FOB Ningbo/Shanghai, CIF, DAP/DDP as needed; packaging and delivery details are confirmed per program. |
| RFQ inputs | 2D drawing + 3D model (STEP), alloy target or mechanical requirement, annual volume, machining scope, inspection package, and surface treatment needs |

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. 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?
T5 and T6 routes are reviewed for suitable gravity-cast aluminum alloys against project requirements. Low-pressure casting is in trial production, so its sample, heat-treatment and validation scope must be confirmed separately.
Can you handle low-volume orders?
Bohua reviews lower-volume gravity or die-casting work against the drawing, tooling and commercial scope. Low-pressure casting is in trial production. Bohua does not offer sand casting; prototype quantity and approval requirements need separate review.
Not sure which process fits your part?
Share your drawing, alloy target, volume, machining scope, and inspection needs so the team can review process fit.
