Changzhou, October 25, 2023-Driven by the dual needs of lightweight and high performance of automobiles, Changzhou Jiasheng Vehicle Parts Co., Ltd. (hereinafter referred to as "Changzhou Jiasheng") announced that its independently developed new generation of investment casting technology has officially started production, providing a disruptive solution for the precision manufacturing of complex structural automotive parts. This technology not only fills the gap in domestic high-end investment casting technology, but also takes **"high precision, strong performance, and low loss"** as its core advantages, becoming a benchmark breakthrough in the field of intelligent manufacturing of automotive parts.
Technical definition: What is investment casting?
Investment casting (Investment Casting), also known as lost wax casting, is a precision process through wax mold making, ceramic shell molding, and metal pouring. Changzhou Jiasheng's upgraded version of the technology incorporates 3D printed wax molds and digital simulation optimization into the traditional process, which can achieve one-time molding of parts with complex geometric shapes, and the precision error is controlled within ±0.05 mm, far exceeding the industry standard.
Application scenarios: What core automotive components can be produced?
Relying on this technology, Changzhou Jiasheng has successfully mass-produced a variety of high-value-added automotive parts:
Power system: turbocharger blades, engine fuel nozzles, variable valve mechanism components;
Transmission: gearbox gear set, clutch precision parts;
New energy field: lightweight battery bracket, electric drive system heat dissipation housing.
Case: The turbocharger blades developed for an international brand have reduced weight by 15% and improved high temperature resistance by 20%, helping to optimize both vehicle power and energy efficiency.
Technical advantages: Why choose investment casting?
Free design of complex structures: Breaking through the limitations of traditional machining, hollow, thin-walled, multi-channel and other special-shaped structures can be manufactured to meet the needs of lightweight and functional integration of automobiles.
Excellent material performance: Suitable for stainless steel, titanium alloy and high-temperature alloy to ensure the stability of components in extreme environments (such as high temperature and high pressure).
Environmental protection and cost reduction: The scrap rate is less than 2%, which reduces energy consumption by 30% compared with traditional forging processes, in line with the trend of green manufacturing.
Maintenance guide: How to extend the life of components?
The Changzhou Jiasheng technical team recommends:
Regular inspection: Perform non-destructive testing on high-temperature components (such as turbine blades) every 50,000 kilometers to check for micro cracks;
Cleaning and maintenance: Use neutral detergent to remove carbon deposits and avoid corrosive substances from contacting precision surfaces;
Original accessories: Match proprietary alloy components, non-standard replacement parts are prone to performance imbalance.
Corporate Outlook: Technology-driven industrial upgrading
Sun Yang, general manager of Changzhou Jiasheng, said: "Investment casting is the 'bottleneck' link of high-end manufacturing. Our technological breakthroughs will promote the leap of domestic auto parts to precision and high-end." At present, the company has reached cooperation with 3 of the world's top 10 automakers, and plans to invest 50 million yuan to expand the intelligent casting production line, with the goal of increasing production capacity by 200% in 2025.
