SpletWhat is Clamping Force in Injection Molding? Clamping pressure in injection molding is the force needed to hold the mold together during injection and it is applied by the clamping unit of an injection molding machine. If this pressure is not monitored, the mold can open prematurely and will create a flash on the related part. SpletSplay is a cosmetic defect that occurs in plastic injection molding, when silver or white streaks appear on the surface of the part. It can be difficult to determine what is truly splay, as its appearance is very similar to other defects.

SpletThe major factor is different wall thickness as a thick section normally shrinks more than a thinner section. Mold design, gate position and process control can minimize this effect, however, the basic material behavior cannot be corrected 100%. Therefore a practical tolerance must be negotiated with the respective production units.
