With the rise of the communications industry, thin and light products have become more and more popular with the public in recent years. And thin wall plastic mold is gradually being valued.
Conventional injection molding processes are already familiar to people, but thin-wall injection molding is not the case. At present, there is no unified definition for thin-wall injection molding. Mahishi and Maloney define it as the flow length thickness ratio L/T (L: Length, flow length; T: Thickness, plastic part thickness; L/T is also referred to as flow length. Compared with) injection molding above 100 or 150 is thin-wall injection molding; Whitten and Fasset define thin-wall injection molding as follows: the thickness of the molded plastic part is less than 1mm, and the projected area of the plastic part is more than 50cm2. It can be seen that it is difficult to give a unified definition; at the same time, with the development of technology, the critical value of thin-wall injection molding will also change. It should be a relative concept.
