China aluminum die casting mold maker
in-house die casting tooling, 10,000+ die casting molds experience.
Superior Die Casting Starts with High-Quality Molds
Precision Die Casting Mold Manufacturer
Die casting is a highly efficient and precise metal casting process. The quality of the die casting mold directly determines the accuracy, surface finish, and overall production efficiency of the cast parts. At Sanon Casting, we specialize in the design and manufacturing of high-pressure die casting molds. All molds are 100% made in-house, ensuring strict quality control, reliable lead times, and cost-effective production for our customers.

Die Casting Mold Manufacturing Process
01. Analysis & Design
- Custom mold design based on product specifications.
- Moldflow simulation to optimize metal flow and minimize porosity.
02. Precision CNC Machining
- High-precision CNC cutting for tight tolerances
- EDM (Electrical Discharge Machining) for complex mold details
03. Heat & Surface Treatment
- High-temperature tempering and nitriding for enhanced wear resistance
- Special coatings (PVD, TiN) to reduce die sticking and extend mold life
04. Mold Assembly & Trial Production
- Precise assembly to ensure seamless mold function
- Trial casting and validation to optimize production parameters
05. Final Delivery & Production Support
- Small batch trial production to verify mold performance
- Mold optimization recommendations for extended service life

What is the typical lifespan of a high-pressure die casting mold?
A high-quality die casting mold typically lasts between 50,000 – 100,000 casting cycles, while long-life molds can exceed 150,000 cycles. The exact lifespan depends on material selection, processing techniques, and maintenance.
What are the key factors affecting die casting mold lifespan?
- Mold steel selection (H13, SKD61, 8407 offer excellent heat resistance)
- Cooling system design (optimized water channels reduce thermal fatigue)
- Heat treatment quality (proper quenching + tempering prevents premature cracking)
- Die casting process parameters (controlling metal temperature and injection speed minimizes mold wear)
- Routine maintenance (regular inspection and cleaning prevent sticking and cracks)
What is the lead time for manufacturing a die casting mold?
Standard lead time is 5Â to 8 weeks, depending on:
- Mold complexity (deep cavities and thin-wall designs require more time)
- Mold size and weight (larger molds take longer to machine and assemble)
- Special requirements (such as sliders, advanced cooling designs, etc.)
How do I choose the right material for a die casting mold?
Mold steel selection varies by country/region. The recommended choices based on application are:
✅ Long-life molds → Recommended 1.2367 / DAC / QRO 90 Supreme
✅ Standard die casting molds → H13 / SKD61 / 1.2344 are the best options
✅ High-impact load applications → H11 / 1.2714 for large die casting molds
✅ High-temperature die casting → H21 / 1.2888 / LD for extreme heat resistance
📌 Sanon Casting provides mold steel selection tailored to different market needs and production requirements.
How can I extend the lifespan of a high-pressure die casting mold?
- Optimize cooling channels to reduce thermal stress and improve fatigue resistance
- Use high-temperature-resistant mold steels with proper heat treatment
- Set reasonable die casting parameters to minimize impact and wear**
- Perform regular maintenance and repairs to prevent cracks or early failures
How can I evaluate the quality of a die casting mold?
✔ Precision machining – tolerance control within ±0.005mm
✔ Uniform cooling – well-designed cooling channels prevent casting defects
✔ High wear resistance – proper heat treatment and coatings reduce sticking
✔ Effective venting system – reduces porosity and improves casting quality
Which industries require high-pressure die casting molds?
Die casting molds are widely used in automotive, electronics, LED lighting, household appliances, and mechanical components, especially for high-precision, high-strength, and high-conductivity aluminum die casting parts.
