CAE Technology plastic mold design and development of an inevita

 

Mold is the production of various industrial products, an important technological equipment, with the rapid development of plastics industry and plastics products in aviation, aerospace, electronics, machinery, ships and automobiles and other industrial sectors to promote applications, products have become increasingly demanding on the mold high, the traditional mold design method has been unable to adapt to product upgrading and improving quality requirements. Computer-Aided Engineering (CAE) technology has become plastic product development, mold design and processing of these weaknesses through the most effective. Compared with the traditional mold design, CAE technology in terms of improving productivity, ensure product quality, or reduce costs, reduce labor intensity and so on, have a great advantage.

Moldflow Corporation is a U.S. listed company specializing in injection molding CAE software and consulting company, since 1976, issued the world's first set of flow analysis software, has been a leading plastic molding CAE software market. In recent years, in the automotive, home appliances, telecommunications, chemicals and daily necessities has been widely applied.

The use of CAE technology can be in the mold before processing on the computer the whole injection molding process analogous analysis, to predict the melt filling, packing, cooling, as well as products of the stress distribution, molecular and fiber orientation distribution, product shrinkage and warping deformation, etc., so that designers can identify problems early, timely modify the workpiece and die design, rather than waiting until later rework die tryout. This is not only the traditional methods of die design a breakthrough, but also to reduce and even avoid mold rework scrap, improve product quality and reduce costs, are of great technological and economic significance.

Plastic mold design not only to adopt CAD technology, but also using CAE technology. This is the inevitable trend of development. Injection molding in two stages, namely the development / design phase (including product design, mold design and mold manufacturing) and production stages (including the purchase of materials, test mold and forming). Traditional injection method is a formal pre-production, as designers use their experience and intuitive design of mold, mold assembly is completed, it normally takes a few test mode, problems are identified, not only need to re-set the process parameters, and even need to modify the plastic products and mold design, this is bound to increase production costs, lengthen the product development cycle. Use of CAE technology, can completely replace the tryout, CAE technology from product design to production of a complete solution, in the mold prior to the forecast of plastic melt in the cavity of the molding process, to help analyzing potential problems, and effectively to prevent the problem from occurring, shorten the development cycle, reduce production costs.

In recent years, CAE technology in the field of injection molding the importance of increasing use of CAE technology, injection molding process can be fully resolved in the problem.
