CPC counter pressure casting technology is an upgraded derivative of low-pressure casting process, mainly applied in high-precision and high-load aluminum alloy casting fields such as new energy vehicle structural parts and high-performance wheel hubs. Different from conventional LPDC and gravity casting molds, CPC counter pressure casting molds have higher structural strength and sealing requirements, adapting to closed reverse pressure casting working conditions. In recent years, with the rapid development of the new energy automobile industry, the demand for high-strength aluminum alloy structural parts has increased year by year, driving the continuous promotion and application of CPC casting molds. Zhejiang Xinfeng Machinery has mature R&D and manufacturing capabilities for CPC casting molds, targeting EV high-load part production scenarios.
The core working condition advantage of CPC molds lies in stable high-pressure sealed casting. Conventional low-pressure casting adopts open or semi-open casting mode, with limited pressure control accuracy, while CPC molds work in 0.3-0.5MPa stable reverse pressure environment. The overall reinforcement design of the mold frame and cavity effectively avoids micro-deformation under long-term high-pressure load, ensuring dimensional consistency of castings in mass production. This working condition adaptability makes CPC molds more suitable for high-precision parts with strict dimensional tolerance requirements.
In terms of product quality control, CPC molds have outstanding advantages in defect suppression. The industry average porosity rate of low-pressure casting aluminum parts is 0.41%, while qualified CPC casting molds can control the porosity rate below 0.12%. The built-in reverse pressure venting structure of the mold can discharge internal gas in real time during metal filling, avoiding pore and inclusion defects that are common in traditional casting processes. For new energy vehicle chassis structural parts with high strength requirements, this low-defect feature significantly improves product fatigue resistance and service safety.
In actual industrial working conditions, CPC molds also show excellent long-term stability. After 100,000 continuous casting cycles, the dimensional deformation rate of high-quality CPC molds is only 0.08%, far lower than the 0.35% deformation rate of conventional LPDC molds. Meanwhile, the precise filling control of the CPC process improves aluminum material utilization from 85% of traditional processes to 92.5%, greatly reducing raw material waste and production costs for casting enterprises. This makes CPC molds the preferred solution for high-end aluminum alloy precision casting scenarios.
