Mechanical Features
Mechanical Features (1) Tie bar clearances and platen size, front to back, top to bottom. Will the planned mold fit on the platens? In some cases it is all right to have the mold larger than these dimensions; it may even…

Cutting by Spark Erosion with Travelling-Wire Electrodes This is a very economical process for cutting through-holes of arbitrary geometry in workpieces. The walls of the openings may be inclined to the plate surface. Thanks to the considerable efficiency of this process,…
Electric-discharge machining Modern mold making would be inconceivable without electric-discharge equipment. With its help,complicated geometric shapes, the smallest of internal radii and deep grooves can be achieved in one working step in annealed, tempered and hardened steel with virtually no…
Injection molds are made by a highly varied number of processes and combinations thereof. Figure 2.1 demonstrates the relative costs for cavities made from various materials. Accordingly, steel cavities appear to be many times more expensive than those made of…
Product Shape Every product has its own characteristic shape. The “shape” may be a simple, flat strip or disk, or a complicated, three-dimensional shape incorporating many features which are desired in the product. Certain rules must be kept in mind…
