What impact will the temperature of plastic mold have on product processing
Plastic mold is known as the "mother of industry". Its application can be traced back to the "ancient times". In the past few decades, with the rolling of the wheel of the scientific and technological revolution, the mold manufacturing industry opened a new chapter. With the rapid development of technology, it has made great contributions to the processing and manufacturing industry.
The temperature of plastic mold is a very important link for injection molding. If the temperature of the plastic mold is well controlled, the processed product will be a good product; If the temperature of the plastic mold is not well controlled, the processed products may be rejected.
So, what kind of influence will the temperature of plastic mold have on the processed products?
- The temperature of the plastic mold will reduce the dimensional accuracy of the products and the product qualification rate,
- The temperature difference between the mold core and cavity is too large, and the plastic part shrinks unevenly, which leads to the bending deformation of the product and affects the appearance of the product.
- If the temperature of plastic mold is too high, the products will be deformed during and after demoulding, which will reduce the shape and size accuracy.
- For some crystalline plastics, the use of high temperature plastic mold is conducive to the crystallization process, to avoid dimensional changes during storage or use.
- For plastic flexible plastics, the use of plastic mold at low temperature can reduce its molding shrinkage, improve the dimensional accuracy of parts, shorten the molding cycle, and improve production efficiency.
- When the plastic mold is filled at low temperature, if the melt speed is not high enough, the internal stress of the product will increase, which is easy to cause warping deformation or application cracking, especially for some high viscosity plastics.
- The temperature of the plastic mold will reduce the fluidity of the plastic melt, making the contour of the part unclear, or even the mold filling is not satisfied, or during the mold filling process, because the temperature of the melt front decreases too much, there will be obvious cold joints, which will lead to the decline of the mechanical properties of the products. Too low temperature of plastic mold will make the surface of products not smooth, resulting in various surface defects.
Temperature plays a critical role in the plastic molding process. It can impact the quality, consistency, and strength of the final product. In this article, we will discuss the impact that temperature has on plastic mold and product processing.
Temperature and Plastic Mold
The temperature of the plastic mold can affect the quality of the molded product. If the mold is too cold, the plastic may not fill the mold completely, resulting in incomplete or poorly formed products. On the other hand, if the mold is too hot, it can cause warping, burning, and other defects in the molded product.
Temperature and Product Processing
Temperature can also impact the processing of plastic products. The temperature of the plastic during processing affects the flow, viscosity, and shrinkage of the plastic. The processing temperature can also affect the surface finish and mechanical properties of the final product.
To ensure the quality of the final product, it is essential to maintain a consistent and appropriate temperature throughout the entire plastic molding process. The temperature must be carefully monitored and adjusted as needed to achieve the desired results.
Conclusion
In conclusion, temperature plays a critical role in plastic mold and product processing. The temperature of the mold can impact the quality of the final product, while the temperature during processing can affect the flow, viscosity, and shrinkage of the plastic. It is crucial to carefully monitor and adjust the temperature throughout the entire process to ensure high-quality and consistent results.
