Key Factors to Determine Plastic Part Thickness

• Whether sufficient for structure strength

In generally, more thick the thickness, more strong for structure. But exceed a kind of range, the shrinkage or air trap etc. issues will be easy to be appeared, then reduce the part strength

• Consideration for the resistance of the part releasing in molding. If the thickness is too thin, there is deformation when eject

• Consider the tightening force in assembly

• If there are metal insert in part, consider the strength around the metal insert. uneven shrinkage if there are metal insert

• Consider the hole strength. there is welding line around hole in the molding. This welding line will reduce the strength of the plastic part

• If all of them you can satisfy, reduce the part thickness as far as possible. Thick thickness part increase the cost, increase the weight, increase the cycle time of molding
