Lower temperatures do indeed affect the processing efficiency of injection machines. Specifically, low temperature of injection molds can have adverse effects on the quality and production efficiency of injection molded products, thereby affecting the overall processing efficiency of injection machines.
Firstly, low mold temperature can cause to poor fluidity of the plastic, resulting in insufficient filling of the plastic in the mold and leaving defects such as bubbles, warping, unevenness on the surface of the injection molded product. This not only reduces the quality of the product, but may also increase the scrap rate, requiring more time and resources to reprocess or process these defective products, thereby reducing production efficiency.
Secondly, low mold temperature can also affect the dimensional stability and shrinkage rate of the product. At lower mold temperatures, the cooling rate of plastic is faster, which may cause significant internal stress in the product, cause to quality issues such as warping and cracking. In addition, insufficient temperature may cause shrinkage, deformation, and other phenomena in certain parts of the product, resulting in the product not meeting the requirements. These require additional time and cost to repair or reproduce, further reducing processing efficiency.
Furthermore, low mold temperature in injection machines can also cause to an extended molding cycle for injection molded products. Due to the poor flowability of plastic at low temperatures, it takes longer to fill the mold and cool to set. This increases the production time of each product, thereby reducing the overall processing efficiency.
In order to improve the processing efficiency of injection machines, it is necessary to maintain a suitable mold temperature range and ensure uniform temperature distribution inside the mold. This can be achieved by increasing the mold temperature, optimizing the process parameters such as pressure and speed of the injection machine, selecting suitable plastic materials, and regularly inspecting and maintaining the injection machine. At the same time, attention should be paid to preheating the mold, controlling the flow and temperature of cooling water, and maintaining the heating and cooling system to ensure the stability and accuracy of the mold temperature.
