Are you curious about how car door panels are manufactured through car door panel injection molds? This video will reveal the answer to you. KRMOLD is a professional manufacturer of car door panel injection molds. During the car door panel injection mold design process, KRMOLD will comprehensively consider important factors such as structural design and functional integration, material selection and process optimization, as well as the design of ejection and cooling systems.
KRMOLD possesses advanced techniques in car door panel injection mold manufacturing. During the cavity processing stage, KRMOLD employs a 5-axis high-speed machining machine (20,000rpm), with an accuracy standard of ±0.02mm. During the electrode manufacturing stage, KRMOLD uses graphite electrical discharge engraving to ensure a surface finish of Ra0.4μm. During the surface treatment stage, KRMOLD undergoes mirror polishing (#15000 grit size) to achieve a glossiness of ≥95GU. In addition, KRMOLD extends the service life of the car door panel injection mold by more than 800,000 cycles through TiAlN coating. Meanwhile, by adopting micro-hole electrical discharge machining technology, ventilation holes of 0.2 millimeters are achieved, solving the problem of air traps and thus producing high-precision car door panels.
