The generation and development of any industry are inseparable from the progress of science and technology. This is also the promotion of the industry generated by the continuously expanding market demand, prompting relevant personnel to continuously update and iterate products. In the processing industry, this requirement is even greater, such as Thick Sheet Thermoforming processing is also moving from traditional processes to more advanced technological processing. So what are its uses and principles? What should we pay attention to when using it?

The unit price of thick sheet thermoforming = product raw material cost, energy consumption, labor and transportation profit. Of course, due to the different labor costs of various manufacturers (involving operational management, production efficiency, etc.), the quotations will also vary. In addition, some powerful manufacturers are thick sheet thermoforming processors. It is also a raw material producer, such as Dite. Then there is a certain advantage in cost control. Thick sheet thermoforming equipment includes: thermoforming machine, punching machine, sealing machine, high-frequency machine, edging machine, etc. In the production of large-scale thick sheet thermoforming processing, the size of the thermoforming machine is particularly important, and it has a certain check on the strength of the thermoforming processing factory. The forming size of large thermoforming equipment can reach 4000*2000 mm, which is quite amazing.
Thick Sheet Thermoforming The principle is similar to that of thin sheet foaming. The positioned sheet is heated in an oven to a softened state, and the thermoforming mold forms a closed space with its surroundings. The air in the mold cavity is instantly evacuated, and the sheet is tightly covered. The process of obtaining the product by cooling and shaping the mold surface.
Thick sheet thermoforming is a cyclical process, each cycle mainly includes: feeding - heating and softening - backblowing pre-stretching - thermoforming - cooling and shaping - demolding and removing parts. After removing the plastic parts, the sheet is repositioned (receiving or automatic) for the next cycle. Thick sheet thermoforming machines have the ability to produce plastic products with large one-time forming size, complex appearance, and imprecise size requirements. In some aspects, it can replace injection molding, fiberglass reinforced plastics, metal shells, etc. The advantage of thick sheet thermoforming is that its cost is 1/10 to 1/20 of the injection mold. It is gradually widely used in various fields of people's daily life, such as automotive interior and exterior decoration, transportation, building materials, packaging, medical devices, household appliances, education, health, and bathing, and sports goods. Today, with the rapid development of the plastics industry, Thick Sheet Thermoforming The use of is constantly expanding, and the status of its thermoforming machinery is becoming increasingly important, and it is difficult to meet the needs of users.
