As a professional in the manufacturing industry, I’ve often marveled at the pivotal role of prensa hidráulica in plastic molding. These powerful machines not only streamline production but also enhance precision and consistency in creating complex shapes. Understanding the intricacies of prensas hidráulicas in plastic molding has been essential for optimizing our processes and meeting the evolving demands of the market. In this article, I will share insights into how hydraulic presses operate within plastic molding applications and their significant impact on efficiency and quality.

Press forming, mainly used for thermosetting plastics, rubber products, etc., can also process long glass fiber reinforced and sheet fillers, and its physical properties and mechanical properties are stronger than injection machines.

1.Hydraulic Press In Plastic Molding-Working process

The plastic is placed in an open mold, and then the pressure oil, the mold is closed, the mold is compacted, the plastic is heated and melted, the mold cavity is filled under pressure, the mold is exhausted to ensure the fixed line, and the mold is taken out.

Basic requirements:

●The pressure is large enough;

●The upper plate can be stopped and returned at any point;

●The upper platen can be speed controlled;

●It is fast when it is empty.
