Polishing may enhance the appearance of the product
Polishing may enhance the appearance of the product. This is the most common requirement in plastic molding. It should be noted, however, […]
Polishing may facilitate ejection
Polishing may facilitate ejection. This applies generally to the finish of the core, including side cores, in cases where the product has projections produced by deep recesses in the cavity or where there is little draft angle specified, the cavity must also be free of any roughness that prevent easy ejection.
Polishing may prevent stress risers in a product
Polishing may prevent stress risers in a product. Any sharp indent or corner in hardened mold steel, usually created during grinding, will increase the risk of breakage caused by stress concentration. Such corners must be polished to remove the shape “ gouges”.
cutting by spark erosion with traveling-wire electrodes
This is a very economical process for cutting through-hole of arbitrary geometry in workpiece. The wall of the openings may be inclined to the plate surface. Thanks to the considerable efficiency of this process, some cavities are increasingly being cut directly into mold plates. […]
the introduction of planetary electric discharge machining
In plain vertical eroding, the eroded configuration is already dimensionally determined by the shape and dimensions of the electrode. Machining of undercuts is not feasible. […]
some tips in operating EDM
This creates craters in both electrodes, the size of which are related to the energy of the spark. Thus, a distinction is drawn between roughing with high impulse energy and planning. […]
introduction to electric-discharge machining(EDM)
Electric-discharge machining is a reproducing forming process, which uses the material removing effect of short, successive electric discharges in a dielectric fluid. […]
Aluminum tooling is going into mold industry
Use of aluminum tooling has been an ongoing discussion for years, and the resulting flow of information has been a key part of aluminum’s growth as a mold material alternative. This continuous growth has led to advances in mold alloys, material size availability, mold design, finishing practices, coatings and welding techniques. More and more success [...]
A new mold manufacturing method
In moldmaking, manufacturers are constantly searching for ways to increase productivity by cutting production time and costs. Today, a hybrid process exists that allows additive machining and milling in the same setup to address those two challenges. […]
CAD/CAM/CAE Integration can benefit mold manufacturing
Mold building in China is a very challenging business. Two of the difficulties are offshore competition and molders’ growing demands for early design involvement. One solution to combat these challenges is mold filling simulation. Its use can help mold builders stay competitive, enhance efficiencies, meet customer expectations and create more business opportunities. Following are four [...]
