The double layer roll forming machine is a kind of roll forming equipment with more advanced components and more favorable performance. And the double layer roll forming machine working principle is similar to the ordinary injector. And the double layer roll forming machine working principle is to adopt the thrust of the screw or plunger and inject the plastified materials with molten state or viscous state into closed die opening. And it is able to get the finished products after solidifying and molding. And the double layer roll forming machine working principle is mainly composed of injection molding, which is a circular process. And each period I composed of ration feeding, fusion plastifying, pressuring injection, mold filling and cooling as well as mold opening and pieces picking up. And after picking up the pieces close the mold to carry out the next circulation.
In addition, in order to understand the double layer roll forming machine working principle better, it is necessary to know the structure of the double layer roll forming machine. The double layer roll forming machine can be classified into plunger type double layer roll forming machine and screw double layer roll forming machine. And it is also able to be classified into hydraulic, mechanical as well as connecting rod type according to the transmission method of the machines. And the double layer roll forming machine is able to be classified into automatic type, half-automatic type as well as manual double layer roll forming machine according to operation methods.
The double layer roll forming machine working principle can be classified according to the types of the double layer roll forming machine. The horizontal double layer roll forming machine is the most common type. And the compound die and injection part of the double layer roll forming machine are on the same level and can be opened along the horizontal direction. And the features of the double layer roll forming machine are that it has short body, which is easy to maintain and operate. And it has low gravity to have stable installation. And the double layer roll forming machine is able to realize the automatic fall of the finished parts. And it has the largest share on the market. And there is also vertical double layer roll forming machine, whose compound die part and injection part are on the same vertical line. Therefore, it has small occupying area with easy to install inserts performance. And it is easy to assemble and unassemble molds. In addition, the materials that are in the hopper are able to be plastified uniformly. And it is necessary to pick up the finished products with hands instead of using machines.
