• Tips on how to design injection mold gate   

    Gate is defined as an opening on the plastic wall through which the molten plastic is injected into the final part. Gate location can make or break your part design.  Therefore, it is very important to do a pre-analysis to decide the location, size, and shape of the gate as all these can greatly affect everything from the structural integrity to the visual appearance of a finished piece. Yet most CAD designers give little thought as to where to and how to put the gate, or injection point, on the part they design. They simply leave that detail to the mold maker.This is a big mistake. Along with choosing the wrong gate size and type is the root cause of many molding difficulties such as welding line, shrinkage, warp and more. The gate has three critical components namely depth, width and land. Depth is the most important factor because it determines how fast gate solidifies. Generally, gating system is composed…
