SOP

SOP (Standard Operating Procedure) is an important principle for the most efficient plastic injection molding process. The SOP principle indicates the appropriate machine size for injection molding for each material type and product shape.

It is also a principle for adjusting the correct injection parameters such as Injection Pressure, V.P. Point, Cushion and Packing Pressure, etc. Which can adjust the injection parameters correctly and appropriately. It will help the production process to be more stable and efficient. The SOP principle can also be used to detect in order to find the cause of various problems that occur in the production process,

for example, the cushioning value in the injection is not consistent due to the checking ring deterioration causing some plastic to flow back into the syringe during injection molding and resulting in unstable production, etc. from such problems If you know the root cause of the problem. This will enable correct and on-the-spot troubleshooting and can also plan to avoid problems in the future. 

Therefore, SOP principles are very important for operators in the plastic injection molding industry to upgrade and increase the efficiency of the production process.
