Properly increase section dimension of gate and runner; the position of gate is set at thick walls of the plastic parts and should be as symmetric as possible; improve mold exhausting condition; set cold-slug well with sufficient capacity to avoid cold material’s entering into the cavity and influencing filling and shrinkage compensation; […]
Optimize prescription of plastics and prefer use resins with low shrinkage; reduce dosage of recycled materials; dry the material as much as possible; […]
Adverse factors of injection machine and product structure design are in the following: […]
Moldmaking can be a difficult business to accurately forecast. Work comes in when the OEM/brand owner is ready, and the ability to impact the project launch is out of the hands of the tool shop. […]
the material additive processes lead fastest to moldings and are therefore the most promising. These also include new and further in RP. Examples of such techniques are laser sintering, […]
Time and cost are becoming more and more important factors in the development of new products. It is therefore extremely important for the injection molding industry to produce prototypes that can go into production as quickly as possible. […]
There has been a long-standing, unresolved debate over whether graphite or copper is a better EDM electrode material. The preference is most always the same in any one geographical region. In North America , the preferred electrode material has shifted from copper to graphite. In Europe and Asia, many argue that copper is the preferable [...]
The use of CAE for injection molding simulation has progressed from flow-front prediction in the late ‘70s to full simulation of the injection molding process, its variants and associated processes. Injection molding simulation benchmarking is the comparison of predicted and actual process parameters. Typically, an extensive study is carried out on a mold, machine and [...]
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. […]
Electric-discharge machining is a reproducing forming process, which uses the material removing effect of short, successive electric discharges in a dielectric fluid. […]
