Question 1

What quality certifications does Bohua Cast hold?

Accepted Answer

Bohua Cast operates under IATF 16949:2016 and ISO 9001:2015 quality management certifications. The IATF certificate scope covers manufacturing of aluminum alloy cast parts and is issued by NQA, valid through 20 November 2027.

Question 2

What aluminum alloys does Bohua Cast work with?

Accepted Answer

Bohua Cast works with a range of common aluminum casting alloys spanning gravity, low-pressure, and high-pressure die casting routes, selected based on part function, mechanical requirements, and heat-treatment compatibility. Alloy selection is discussed with the buyer during RFQ review to align with end-use performance and downstream operations.

Question 3

What is the typical lead time for custom aluminum gravity die castings from Bohua Cast?

Accepted Answer

Bohua Cast's tooling-to-first-sample lead time depends on part geometry, mold design complexity, and casting validation scope—covering mold design, mold fabrication, trial casting, and initial dimensional reporting. Engineering review and preliminary quotation are provided after receiving drawings and specifications. Production lead times for serial runs depend on part complexity, annual volume, and processing scope.

Question 4

What industries and applications does Bohua Cast serve?

Accepted Answer

Bohua Cast serves four primary industries: (1) Automotive — engine components, transmission housings, and structural brackets for automotive supply chains; (2) Industrial and Petrochemical — pump housings, valve bodies, gearbox housings, and impellers for fluid and mechanical systems; (3) Rail and Transportation — structural aluminum components for rail and transportation programs; (4) Consumer Appliances — precision castings for appliance manufacturers. Part sizes are program-dependent, with maximum dimensions up to 1,200 mm.

Question 5

What quality control processes does Bohua Cast use during production?

Accepted Answer

Bohua Cast quality control can include melt chemistry verification with an Oxford Foundry Master Pro OES, dimensional checks with a Hexagon Global S 7.10.7 CMM, 3D scanning, tensile or universal testing, X-ray inspection, helium leak testing, and AIAG PPAP records when the buyer defines that approval scope.
