快速冷却和快速加热成型技术已成功应用于碳纤维

High gloss seamless injection molding technology, also known as Rapid Heat Cycle Molding (RHCM). This molding process mainly involves injecting high-temperature steam or hot water before injection molding, quickly raising the temperature of the mold to 100-150 ℃ to ensure the fluidity and filling of the plastic in the mold cavity, thereby solving surface defects of the product. At the same time, in order to improve production efficiency, cold water is injected after the product is pressurized to quickly cool the mold surface to 35-85 ℃, accelerating the cooling and shaping of the product in the mold cavity.

High gloss seamless injection molding process: After the product is ejected from the mold cavity, inject high-temperature steam or high-temperature superheated water → wait for the mold temperature to rise to the TG value of the plastic (upper limit temperature reaches) → start injecting plastic into the mold cavity → after the injection molding pressure is completed → inject high-pressure air (remove residual high-temperature steam or high-temperature superheated water) → inject cold water again → wait for the mold temperature to drop to (lower limit reaches) After setting the value, mold opening → product ejection enters the next cycle.

Ode Machinery took advantage of the commonality between the high gloss seamless injection molding process and the carbon fiber molding process to improve and upgrade the original high gloss seamless injection molding technology. It successfully developed a special machine suitable for rapid cooling and heating of carbon fiber molds, solving the technical bottleneck that has plagued carbon fiber molding technology for more than 10 years. The traditional cold pressing and hot pressing processes of two molding machines have been reduced to one molding machine directly completing the cold pressing and hot pressing processes, shortening the molding cycle by more than 40-50%, reducing the mold handling process between cold and hot molding machines, and reducing the cost investment of molding machines for enterprises, saving space occupied by the site.
