FAQs
Die casting is a metal casting process where molten metal is forced under high pressure into a reusable steel mold cavity6. The mold, composed of two hardened dies, operates similarly to an injection mold, enabling high-volume production of small to medium-sized parts with excellent surface finish and dimensional consistency6. Key steps include melting the metal (commonly aluminum, zinc, or magnesium alloys64), injecting it into the die under high pressure, and cooling to form the final part6.
This process is widely used in automotive manufacturing for lightweight, complex components like engine blocks and structural frames41. For example, Tesla employs 6,000-ton gigacasting machines for front and rear underbody parts1, while AITO M9 uses a 9,000-ton press for rear sections1. Advantages include cost-effectiveness (due to reusable dies), rapid production cycles, and high structural integrity46.
1. Wall Thickness
Maintain uniformity (2.5–4 mm for aluminum alloys), avoid thick sections (>6 mm) to prevent gas porosity; use ribs/gussets instead of localized thickening, and ensure gradual transitions to reduce stress.
2. Draft Angle
Minimum 0.25°–1.5° (1°–3° for deep cavities or textured surfaces); align draft direction with mold opening to avoid undercuts.
3. Fillets
Internal radii ≥0.5 mm (recommended: 1/2 to full wall thickness) to enhance strength and fill; round external edges for easier mold maintenance.
4. Gating System
Place gates near thick sections for laminar flow to minimize air entrapment; tapered runners and small gates require high pressure but simplify trimming.
5. Venting
Add 0.1–0.15 mm deep vent slots along the parting line; critical components use vacuum-assisted systems with dual vents to reduce porosity.
6. Geometric Simplification
Eliminate undercuts, optimize parting lines for minimal complexity, and adopt symmetry to reduce thermal distortion and improve mold stability.
The tolerances for die casting vary depending on the process and part dimensions. For pressure diecasting, the flatness tolerance is typically 0.2 mm for dimensions up to 75 mm, with an additional 0.075 mm added per 25 mm increase in size4. These values reflect standard production practices optimized for cost-effectiveness. Higher precision may require specialized processes or additional post-casting machining. For example, surface roughness in high-pressure die casting can achieve Ra 1.6–6.3 μm under optimal conditions1, though dimensional tolerances remain primarily governed by the casting size and material flow characteristics. Designers should specify tighter tolerances only where functionally necessary, as achieving them often increases production complexity.
Our design team utilizes specialized software for product development and mold flow analysis, ensuring designs meet production requirements. Through pre-production simulations, we optimize processes to reduce trial runs and improve yield.
We are well-versed in PPAP processes and can prepare complete Production Part Approval documentation, guiding clients through the review procedures.
Our ISO 9001:2015 certified quality management system ensures full-process monitoring from raw materials to finished products, including first-article inspection, in-process checks, and final inspection.
We implement annual improvement plans, regularly optimizing processes and efficiency through customer feedback and production data analysis.
We offer flexible lead times of 2-10 weeks, tailored to design complexity and client requirements. Through parallel design confirmation and modular manufacturing solutions, standard projects can be delivered in as fast as 2 weeks, with complex projects completed within 10 weeks maximum.
