1.New Tooling New tooling considerations involve only a few items that are not part of a conventional tooling design. Quality input is imperative to determine location and shape of gas channels and for design advice regarding ribs, bosses and heavy sections of the molded product. […]
Die surface machining has been in the area of attention. With the new technologies, new technology development, many of the traditional approach has been not very applicable. The complex shape of the mold, the best way to deal with the surface of the laser, it is virtually non-deformation, surface hardness than the conventional way to [...]
Different techniques are often employed to produce a part prototype. Choosing the best solution to meet customer requirements can sometimes seem confusing. Makino’s application engineers created the following process comparison to demonstrate several approaches that might be considered for a cell phone mold application. […]
1) Size, it is said isn’t everything, and that is certainly true in the case of the latest developments in injection moulding. The emerging micro moulding is taking injection moulding technology down to a new scale and a new level of intricacy and accuracy that has simply not been possible until now. Parts weighing no [...]
Hasco has developed a mini hot runner system for direct injection moulding, without gating, of small parts and micro-parts. […]
There are no inherent disadvantages to the Gas Assist process. There are, however, a few circumstances where it would not be recommended. […]
1) Process Basics Gas Assist Injection Molding is a process enhancement to conventional injection molding, involving the injection of high-pressure nitrogen gas into the resin melt-stream immediately after injection of the resin. […]
Mazda Motor Corporation has developed a new plastic molding technology that enables a substantial reduction in the weight of plastic parts used in vehicles. This plastic molding manufacturing technique cuts the consumption of plastic resins that are used as raw material by approximately 20 to 30 percent, with associated reductions in vehicle weight. [...]
Molding Technologies The manufacture of aspherical lenses and diffractive-optical elements, which have structures designed to diffract light on their surfaces, is made possible through mold-making technology, the most advanced technology used in lens production. […]
The process cycle for injection molding is very short, typically between 2 seconds and 2 minutes, and consists of the following four stages: […]
