Aluminum Casting RFQs Reviewed From Drawings
China aluminum casting manufacturer for A356 / ZL114 gravity casting, CNC machining scope, leak-test planning, and buyer-defined inspection records.
Buyer-facing RFQ contexts supported since 2009
Project-relevant records can be requested during qualified supplier review.
Buyer Verification
Check the evidence before choosing the RFQ path.
The homepage is a short company summary. Buyers should verify certification scope, supplier facts, inspection support, and quote readiness on the linked pages before treating any RFQ assumption as confirmed.

Four Processes.
One Expert Team.
We review the process route against drawing geometry, volume, alloy, machining, and inspection requirements.
Gravity Casting
A356 · ZL114 · drawing review
Permanent mold gravity casting for structural housings, brackets, manifolds, and pump or valve programs where alloy, wall section, machining, and inspection scope must be reviewed from the drawing.
Low-Pressure Casting
Leak-test · Porosity-sensitive housings
Counter-gravity fill route reviewed for housings and components where fill consistency, porosity risk, and buyer-defined leak-test criteria affect approval.
Die Casting
ADC12 · High volume
High-pressure die casting for thin-wall, high-volume components when geometry, alloy, finish, tooling cost, and inspection expectations fit the process.
Sand Casting
Prototype · Large-format review
Flexible expendable molds for prototype, low-volume, repair, or large-format parts when the drawing and tolerance scope fit sand casting economics.
Alloys
Alloy Choice Starts
With the Drawing.
Gravity / Low-Pressure
Structural housings, brackets, pump or valve programs
Gravity / Low-Pressure
GB-standard structural and industrial RFQs
Die Casting
High-volume thin-wall, complex geometry
The Facility
13,420 sqm of Modern
Casting Infrastructure
Automated gravity casting lines, CNC machining centers, T6 heat treatment furnaces, and inspection resources including X-ray, CMM, and spectrometer are reviewed by project scope in Fenghua, Ningbo.
