Standard for precision injection molding machines

Precision injection molding machines are machine equipment suitable for producing precision plastic products. So how to determine whether this injection molding machine is a precision instrument. Let's explore below.
There are usually two basic indicators for precision injection molding machines, one is the deviation of the repeated size of the finished product, and the other is the deviation of the repeated weight of the finished product. The former is because it is difficult to compare the size and thickness of the finished product. The latter represents a comprehensive level of injection molding machines. The weight repetition error of ordinary injection molding machines is around 1%, while more precise instruments can reach 0.8%
More precise injection molding machines also require injection molding machines with relatively high injection pressure and high injection speed. This requires a corresponding accuracy in terms of pressure, flow rate, temperature, etc., to ensure the reproducibility of the finished product process and the accuracy of product repetition, etc.
