In plastic step sucking back is very important too. Sucking back include front sucking back and back sucking back It setting sucking back to prevent flow and line. It sets sucking back speed and pressure within 20-50% and distance within 2-5cm. TOO long distance make cyclinder reserve air and cause bubbleat next molding.

熔胶过程还有一个比较重要的环节，那就是松退，松退分前松退和后松退，其作用一般是为了防止流涎和抽丝，设定值速度和压力都在20%-50%间，设定的行程一般在2-5cm间，太长的行程可能会使料筒里面贮存空气，导致下一模出现不期望的气泡。
