Abstract
Description
technical field
[0001] The present invention relates to the field of mold manufacturing, in particular to a tensioned film assembly for material forming and a method for using the same. Background technique
[0002] Compression molding is a method of adding premix or prepreg between a metal female mold and a male mold to form a composite product. This method has a high degree of automation, high production efficiency, low cost, is suitable for mass production, and produces products with good appearance and high dimensional accuracy, so it is widely used. However, since this method needs to add premix or prepreg to the female and male molds, the filling amount of the premix or prepreg is strictly controlled, and too much or too little filling will cause various problems. or substandard products. In addition, since the premix or prepreg is in a closed or semi-closed space, during the molding process, it is necessary to carry out an exhaust operation, and strictly control the...
