HPI High Precision Injection 高精准燃油直喷系统
Using average shrinkage rates of injection-molded parts to decide the dimension of mold cavity can not satisfy the demand of high precision injection-molded parts.
采用一般的平均收缩率方法来确定模具型腔的成型尺寸，已难以满足精密注塑成型制品的精度要求。
Industrial plastic parts are usually requested to have high precision and complicated shapes, so it is important to control the shrinkage rates of injection-molded parts.
在这些应用场合，不仅要求塑料制品的精度高，而且塑料制品形状也比较复杂，这使得对注塑成型制品收缩率的控制变得十分重要。
Because of high efficiency, high precision and low cost, Injection mold is the first choice for batch manufacturing.
由于高效率、高精度和低成本的显著特点，注塑成型不失为批量生产塑料制件的首选方法。
