Diesel engine casting RFQ
Diesel Engine Cylinder Head Aluminum Casting Supplier China
Diesel engine cylinder head buyers need more than a foundry process label. The RFQ has to define coolant jackets, combustion-face machining stock, heat-treatment expectations, pressure-test scope, and inspection records before a supplier can quote responsibly.

Open evidence linkAluminum Cylinder Head RFQ FAQ
What should a cylinder head RFQ include?
Send 2D drawings, 3D models, alloy and heat-treatment targets, coolant and oil passage requirements, machining datums, pressure-test criteria, inspection records, annual volume, and PPAP expectations.
Which casting route fits aluminum cylinder heads?
The route depends on geometry, cores, volume, and validation scope. Gravity casting or sand casting may be reviewed for complex passage geometry before Bohua recommends a quotation path.
Can Bohua quote machining with the casting?
Yes. Buyers should define machining allowance, critical datums, surface finish, CMM reporting, and sample approval requirements so casting and CNC scope can be quoted together.
Can you provide PPAP for engine-related parts?
Bohua can review PPAP Level 3 or Level 4 requirements after the drawing, process route, inspection plan, and customer-specific requirements are shared.
