The system can be heated under stable pressure conditions, but the temperature must not rise too quickly during the process. Monitor the pressure to ensure it remains stable; do not increase the temperature when it's unstable. Once the pressure stabilizes at the equipment's set value, the mold temperature controller has been successfully adjusted.
How to use a mold temperature controller: Connect the power cord, make sure it's grounded, then turn on the power switch to start the pump. For oil-type mold temperature controllers, it takes 5 minutes to heat up. To maintain a certain pressure between the controller system and the mold, heat up only to prevent the electric heating tube from burning out. For water-type mold temperature controllers, check if the water supply pressure from the user's factory is greater than 1.5KG when starting up. If the pressure is low, the water temperature controller will not start, thereby protecting the mold temperature controller.
What is the primary function of a mold temperature controller?
Purpose of the mold temperature controller: primarily to effectively control the mold temperature, allowing us to better achieve product quality during the production process.
Maintain the mold temperature constant at the working temperature. If successful, the cycle time can be optimized to ensure consistent high-quality injection molded parts. Mold temperature affects surface quality, fluidity, shrinkage rate, injection cycle, and deformation. Excessive or insufficient mold temperature can have different effects on different materials.
For plastics, the primary purposes are as follows:
1. Maintain the mold temperature constant at the working temperature.
2. For thermoplastic materials, a higher mold temperature generally improves surface quality and fluidity, but it extends the cooling time and injection cycle. A lower mold temperature reduces shrinkage within the mold, but increases the shrinkage rate of the molded parts after demolding.
3. For thermosetting plastics, a higher mold temperature typically reduces cycle time, with the duration determined by the cooling time required for the parts.
