Due to its high productivity, efficiency, and manufacturability, injection molding is a popular method for manufacturing plastic products. The mold is designed with special inserts. Selective laser melting 3D printing has been used to manufacture inserts with conformal cooling channels inside.
Rapid tooling technology is being developed and proven to be a reliable method that can compete with subtractive technology for tooling. Although people are looking for affordable alternatives to avoid the use of tools, in most cases, rapid manufacturing is an alternative method.
The research results show that, compared with the traditional cooling channel, the conformal cooling channel can shorten the cycle time by about 30%. Make the mold smart, and the temperature of the mold will be monitored by the sensor system.
