Aline's plastic injection molding process equipment designed for cooling is mainly related to thermoplastic materials. At room temperature thermoplastic materials such as polypropylene, nylon and PET are solid. In order to shape these materials they must first be heated to their specified molten temperature. Once their molten temperature has been reached they can be manipulated into a new shape. When formed into their new shape they must then be cooled to solidify the configuration and ensure high quality performance.
In the thermoplastic injection molding process, cooling accounts for approximately 80% of the cycle time. Once the mold is filled, it is critical that consistent and reliable cooling be obtained. Our equipment operators and technicians check each channel to ensure proper cooling and develop a mold surface map of temperatures to determine the actual temperature of the mold at key locations.
This information gives us an accurate understanding of how each area of the mold is cooled. When each area of a mold has reached its proper temperature for an injection molding prototype we have all the means necessary to duplicate and maintain proper cooling during full-scale production. Only by generating information regarding the mold surface temperature can we ensure an efficient plastic injection molding process.
