What We Do
Casting Capabilities
Four aluminum casting processes. One quality system. Parts from 0.1 kg to 50 kg, with dimensions exceeding 1,200 mm.
All processes · IATF 16949 quality system
Quick answer for buyers
Bohua supports four casting routes — gravity, die, low-pressure, and sand — with in-house CNC machining, T6 heat treatment, 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
| Location | Ningbo, Zhejiang, China |
|---|---|
| Process fit | Gravity casting for structural, pressure-conscious parts needing T6 and low porosity; die casting for high-volume thin-wall programs; low-pressure for structural housings with consistent fill needs; sand casting for complex or lower-volume geometries |

Capabilities FAQ
What measurement and verification equipment do you have?
Bohua uses internal-soundness verification equipment, dimensional verification systems, optical emission spectrometer, and tensile testing machine, plus routine process checks to verify chemistry, dimensions, internal quality, and mechanical properties before shipment.
Can you support automotive quality system and documentation requirements?
Yes. Bohua operates under automotive-grade and ISO quality management systems and can support automotive-style documentation, control planning, dimensional reporting, and serial-production discipline depending on project scope.
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.
