Critical characteristics
Agree drawing revisions, datum features, cleanliness and functional interfaces.
Automotive housing programs
Automotive Die-Cast Housings.
Drawing-based aluminum housings developed around structural load paths, sealing interfaces, bearing alignment, traceability and automotive production controls.
Define the supplied condition, critical dimensions and acceptance plan in the drawing review. Published process references depend on material, geometry and the agreed order scope.
From Sample Approval to Repeat Supply.
Project approval
Define the required FAI, APQP or PPAP submissions for the component and producing site.
Traceability
Align material, inspection and change-control records with the approved program.
Production route, manufacturing responsibility, available documentation and acceptance criteria are confirmed for the particular product and order.
Manufacturing Scope
Bearing alignment, sealing and production control.
Equipment route
130–4,400T aluminum HPDC network selected by projected area
Machining
Bearing bores, sealing lands, ports and threaded features
Quality planning
APQP, FAI and PPAP scope agreed at quotation
Validation
CMM, leak testing and material records by control plan
Feature review
Connect critical interfaces to production approval.
Bearing saddles, reinforcing ribs and perimeter fixing holes perform different jobs in the open housing. Identify the finished locating surfaces separately from the surrounding cast geometry.
Link each critical characteristic to its drawing revision, inspection method and approval record. This connects the individual housing interface to the production-control requirements above.

How to Source Automotive Die-Cast Housings
Automotive Aluminum Die-Casting Process Selection
Automotive aluminum die-cast housings are routed by projected area, casting weight, wall section, structural duty and sealing risk. Ningbo Empire reviews the 3D model before selecting a 130-4,400T HPDC cell, vacuum strategy, machining allowances and control-plan scope.
Information Needed for an Automotive Housing Quote
For a useful quotation, provide the alloy or performance target, finished weight, annual volume, critical datums, leak requirement, surface treatment and PPAP level. Early DFM review is especially important around bearing bores, gasket lands, threaded bosses and insert locations.
Frequently Asked Questions
Can you support automotive PPAP?
Yes. PPAP level, dimensional layout, material records, capability studies and sample timing are defined in the quotation and project quality plan.
Can inserts be cast into the housing?
Yes when insert retention, galvanic compatibility, positioning tolerance and thermal-cycle requirements are reviewed before tool release.
Prepare the project review
