The influence of mold temperature on product molding is significant. Proper mold temperature can promote the flow and melting of plastic, while helping to reduce internal stress and defects and improve product quality and stability.
–Excessive mold temperature can easily cause thermal decomposition of plastics, affecting the appearance and physical properties of plastic parts.
–Low temperature molds can lead to an increase in shrinkage, warping, and surface roughness of plastic parts. This is because at low temperatures, the fluidity of the melt decreases. Which can easily lead to phenomena such as short distance melting and cracking.
- Set the mold temperature reasonably:. Set the mold temperature reasonably according to the type and performance of the plastic and the requirements of the product.
- Control the cooling time: According to the mold temperature and the characteristics of the plastic. The cooling time should be reasonably controlled to reduce internal stress and defects.
- Monitor temperature changes: Regularly monitor changes in mold temperature to ensure that it is stable within the optimal range.
- Optimize process parameters: comprehensively consider mold temperature, injection pressure, injection time and other factors to optimize process parameters. And improve the quality and stability of plastic products.
Control of mold temperature is crucial to the success of the injection molding process. In order to control the temperature of the mold, a special temperature control machine is usually used. These devices can perform temperature control near the inlet and outlet of the mold to better control the quality of plastic parts.
