Both the shrink mark and shrinkage porosity are defects of injection products due to the molding shrinkage at thick walls where no sufficient follow-up compensation is made. During the injection process, the surface layer of products often condenses first, followed by the center layer, which will cause sinking on the surface of parts with thick [...]
Every people who works in manufacturing industry must know manufacturing cycle meaning– Eliminating secondary operation further reduces costs. […]
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 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 [...]
for the production of injection and die-casting molds, a combination of milling and eroding may also be performed. The amount of milling should be maximized since the machining times are shorter on account of higher removal capability. However, very complex contours, filigree geometries and deep cavities can be produced by subsequent spark-erosive machining. The electrode [...]
In the injection molding industry, it is common for companies to rely on trial-and-error methods to solve production problems. Without process simulation, operators suggest a mold configuration, which “should work” for a specific part geometry, based on experience. Factors such as tempering or processing times are defined later during the first production trials. It is [...]
for molds with small batch of production and of low precision, the guide pillar can be directly fitted with pilot hole on the plate. The hole should be generally made into through hole, […]
abrasion loss during use. The abrasion and restoration during production can lessen the dimension of cores and enlarge the dimension of cavities.
but direct gate also has it’s own disadvantages, at first, it is more difficult to remove the slug from a direct gate, […]
The success of a mold manufacturer boils down to its ability to deliver high quality products at the shortest possible time and the lowest possible cost. Following are some mold design best practices that will help you achieve these goals. […]
