In the automotive manufacturing industry, the precision and durability of die-casting molds directly affect the performance and production efficiency of the entire vehicle. The Automotive Engine Die Casting Mold we launched is designed for high-standard, mass-production scenarios, and reflects professionalism and ingenuity in material selection, processing technology and structural design.
This Automotive Engine Die Casting Mold in our factory uses imported H13 (SKD61) hot-working die steel. After three tempering treatments, the hardness reaches HRC48–52, and the heat fatigue resistance is about 30% higher than that of conventional molds. In other words, even in a long-term high-temperature and high-pressure die-casting environment, it can maintain stable performance, and its normal service life can reach more than 80,000 molds, which significantly reduces the frequency of mold replacement and maintenance costs for customers.
The molding cavity of each set of molds is finely polished by hand by experienced technicians in our factory, and the surface roughness is controlled within Ra≤0.8μm, the flatness error of the parting surface does not exceed 0.02mm, and the joint surface is manually fine-tuned to achieve tight closure without flash. Such a process not only improves the dimensional accuracy of the finished product, but also reduces the defective rate, making the mold production process more efficient and stable.
In addition, we adhere to the manual control of traditional processes. In terms of precision machining, the cutting accuracy of the mold can reach ±0.005mm, and complex curved surfaces are formed in one go, reducing repeated machining errors. In the pretreatment stage, we annealed the mold at 650℃ and tempered it at 200℃, and then arranged a 30-day natural aging. Technicians regularly monitor its deformation to eliminate internal stress to the greatest extent and reduce the risk of cracking in mass production.
For customers, using this die-casting mold can bring many benefits: a longer service life means less downtime and higher capacity utilization; higher machining accuracy means less part rework and higher consistency; and more stable mold performance also helps to control the overall production cost and improve the market competitiveness of the end product.
This mold is suitable for high-pressure die-casting of various automotive engine parts, such as cylinder blocks, cylinder heads, oil pans, etc., and is an ideal choice for mid-to-high-end automotive parts manufacturers. We can also provide customized development services according to customer needs to help customers quickly respond to market changes and enhance brand value.
