3 Key Tips to Reduce Costs in Aluminum Die Casting Design

  1. Optimize Wall Thickness: Aim for uniform walls (2.5mm – 4mm) to avoid shrinkage defects.
  2. Add Draft Angles: Ensure a minimum of 1-2 degrees to facilitate part ejection and extend mold life.
  3. Consolidate Parts: Use die casting to combine multiple components into one to save assembly costs.

Kingrun Process Flow:

1. DFM (Design for Manufacturability)

Review DFM (Design for Manufacturability) to optimize product structure, gate, and cooling system; design and manufacture high-precision die-casting tooling and conduct mold trial validation.

2.Tooling (Die-Casting Tooling Design & Manufacturing)

Tooling is the core equipment for casting production, and its precision and quality directly determine the quality of castings. This stage is carried out based on the optimized DFM design, including tooling design, material selection, processing, and trial validation.

3. Casting (High-Pressure Die Casting)

Casting is the process of producing product blanks by injecting molten metal into the tooling cavity under high pressure and rapid filling. This stage requires strict control of process parameters to ensure the internal quality and surface quality of the castings.
4. CNC
After casting, the blank has certain dimensional deviation and surface roughness, so CNC machining is required to achieve the precise dimensions, shape, and surface quality specified in the 2D drawings. This stage is a key link to ensure the final product precision.

5. QC (Quality Control & Final Inspection)

Implement full-process QC (Quality Control), including dimensional inspection by CMM equipment, appearance check, material and performance testing; ensure compliance with standards before shipment.
