Changzhou, November 1, 2023-Against the background of the blowout of demand for lightweight and efficient manufacturing of new energy vehicles, Changzhou Jiasheng Vehicle Parts Co., Ltd. (hereinafter referred to as "Changzhou Jiasheng") announced that its independently developed ultra-high pressure vacuum die-casting technology has achieved a breakthrough in mass production, injecting new momentum into the precision manufacturing of core automotive components. With **"zero defects, high strength and toughness, and second-level molding"** as its core advantages, this technology fills the gap in domestic high-end die-casting technology and helps automakers reduce costs and increase efficiency.
Technical definition: How does die casting reshape manufacturing?
Die casting is an efficient process of injecting molten metal into a mold and rapidly cooling it through ultra-high pressure (more than 6,000 tons). Changzhou Jiasheng innovatively integrates vacuum degassing technology and intelligent temperature control system to eliminate bubbles and oxidation defects in traditional die-casting parts, increase product density by 30%, and achieve an accuracy of ±0.1 mm, comparable to machining standards.
Core products: Which automotive parts are enabled?
Based on this technology, Changzhou Jiasheng has mass-produced a variety of high-performance components:
New energy three-electric system: integrated battery tray, motor housing, electronic control heat dissipation substrate;
Body structure: door frame, shock tower, A/B pillar reinforcement;
Powertrain: gearbox housing, engine bracket.
Case: The integrated battery tray developed for a leading car company reduced weight by 25%, increased torsional rigidity by 40%, and shortened the single-piece manufacturing cycle to 90 seconds.
Technical breakthrough: Why choose ultra-high pressure vacuum die casting?
Lightweight and strength: Using high-strength aluminum alloy (such as AlSi10MnMg), the strength of the components is increased by 50%, the weight is reduced by 20%, and the endurance and safety are win-win.
Cost efficiency revolution: Compared with traditional stamping and welding processes, the number of parts is reduced by 80%, and the labor cost of the production line is reduced by 60%.
Green intelligent manufacturing: material utilization rate exceeds 95%, production energy consumption is reduced by 35%, and carbon emissions are reduced by 50%, which is in line with the carbon neutrality goal.
Maintenance Guide: How to ensure the life of die castings?
Changzhou Jiasheng technical team tips:
Regular anti-corrosion treatment: spray nano-coating on exposed parts (such as battery trays) to resist salt spray corrosion;
Stress monitoring: check micro cracks of key structural parts (such as shock towers) every 20,000 kilometers;
Original factory adaptation: avoid mixing parts of different alloy materials to prevent electrochemical corrosion.
Industry Outlook: Technology drives industrial upgrading
Sun Yang, general manager of Changzhou Jiasheng, said: "Die-casting technology is the 'winner' of lightweight automobiles. Our goal is to redefine global standards with Chinese smart manufacturing." At present, the company has reached strategic cooperation with new energy giants such as Tesla and BYD, and invested 120 million yuan to build a fully automated die-casting production line. The production capacity is expected to exceed 2 million pieces in 2024.
