Product Description
Service Process for High Precision Investment Casting Brackets for Automotive Chassis
1. Pre-Production Collaboration
(1) Requirement Confirmation
Confirm bracket specifications including overall dimensions, load requirements, installation position on chassis, material grade, tolerance requirements, surface condition, order quantity, and delivery schedule.
(2) Drawing & File Review
Receive 2D drawings or 3D models showing bracket geometry, mounting points, wall thickness, fillets, and machining reference surfaces.
(3) DFM & Casting Feasibility Analysis
Analyze design suitability for investment casting, optimizing structure, wall thickness uniformity, and draft angles to ensure dimensional stability and mechanical performance.
2. Investment Casting Process Planning
(1) Material Selection
Select suitable casting materials such as carbon steel, alloy steel, or stainless steel based on strength, fatigue resistance, and automotive application requirements.
(2) Wax Pattern & Mold Preparation
Produce precision wax patterns and ceramic shells to replicate complex bracket geometries with high accuracy.
(3) Process Control Planning
Plan pouring, cooling, and heat treatment processes to achieve consistent mechanical properties across batches.
3. Casting Production & Quality Control
(1) Casting & Shell Removal
Carry out molten metal pouring, solidification, and ceramic shell removal to obtain near-net-shape brackets.
(2) Heat Treatment & Machining (If Required)
Perform heat treatment to improve strength and toughness. CNC machining is applied to critical mounting surfaces and holes when required.
(3) Inspection & Verification
Inspect dimensions, surface quality, and key features using gauges and measuring tools. Mechanical property checks are performed as required for automotive chassis components.
4. Post-Processing & Delivery
(1) Surface Treatment (Optional)
Provide surface treatments such as shot blasting, painting, coating, or plating to improve corrosion resistance and appearance.
(2) Cleaning & Packaging
Clean finished brackets and package securely to prevent impact damage during transportation.
(3) Delivery
Deliver finished investment casting brackets according to agreed logistics terms. Stable lead times are available for prototype and mass production.
