Compression molding, also known as mechanical stretch molding

There are many methods of plastic thermoforming, which can be divided into two categories: compression molding and differential pressure molding according to the molding power. According to the forming mold, it can be divided into several methods such as single male mold, single female mold, paired mold, no mold, etc. Compression molding, also known as mechanical stretch molding, is a molding method in which plastic sheets are molded into various parts with the help of external mechanical pressure or self-weight in the form of a single mold or a pair of molds. The male mold means that the shape of the mold is convex, and the female mold means that the shape of the mold is concave. The mold only shapes one side of the product, and the other side is exposed to the air, which is different from the one-time molding process. This method is basically applicable to all thermoplastics.

What is the difference between in-mold eager cutting and in-mold cutting?

What is the difference between in-mold eager cutting and in-mold cutting? In-mold cutting workflow: mold clamping→injection→pressure holding→cooling→mold opening→ejection→manual shroud or jig shroud. In-mold eager cutting workflow: mold clamping→injection→pressure keeping→water opening→cooling→mold opening→ejection. Appearance of the product after in-die cutting: Cold cutting is achieved after the plastic part is cooled, so it will turn white at the cut, and there will be stress that will affect the appearance and mechanical properties, and the artificially processed nozzle will have poor appearance quality. The appearance of the product after hot-cutting in the mold: the separation of the nozzle and the plastic part is realized when the plastic in the mold cavity is still in a molten state after the pressure holding is completed, so there will be no stress, which can not only ensure the appearance quality of the plastic part after the nozzle position is separated . and guarantee The appearance quality of the product is consistent, thereby improving the product qualification rate.
