The mass production quality stability of casting molds depends on standardized full-process inspection systems, rather than single finished product detection. Most batch quality problems of industrial molds are caused by missing inspection and non-standard monitoring in processing and assembly links. Zhejiang Xinfeng Machinery implements 12-step standardized quality control procedures covering design, machining, assembly, debugging and delivery, realizing full-trajectory quality monitoring of each set of molds.
Design review is the first barrier of quality control, with 100% full-coverage 3D modeling and CAE simulation review. Professional engineers comprehensively check the rationality of mold casting scheme, cooling circuit layout and venting structure, eliminate potential structural defects and process risks in the design stage, and avoid large-scale modification and quality fluctuation in subsequent production links.
Real-time monitoring in precision machining stage ensures processing stability. In CNC high-speed processing links, staff conduct full-dimensional sampling inspection every 2 hours to monitor tool wear, processing deviation and surface quality, timely adjust processing parameters, and control all dimensional errors within the qualified tolerance range, effectively avoiding batch precision deviation caused by tool aging.
Precision assembly and full-performance trial test ensure practical production adaptability. The mold cavity, core, cooling system and exhaust components are precisely fitted with assembly gap controlled within 0.01mm to ensure flexible mold opening and closing and no liquid overflow. All finished molds undergo 100% simulated mass production trial casting to verify filling uniformity, cooling efficiency and defect control ability, ensuring stable performance in customer mass production.
Before delivery, 28 core parameters including mold overall dimension, surface finish, cooling flow rate and venting smoothness are fully inspected, with 100% inspection coverage. Cooperated with standardized anti-rust packaging and complete technical document delivery, the overall mass production defect rate of molds is controlled below 0.8%, fully meeting the batch production quality requirements of global automotive customers.
