      What Is Thermoforming Film

      Apr 11, 2023

      Thermoforming is a manufacturing process that heats the plastic plate to a soft formation temperature, forms a specific shape in the mold, and trims to create available products. When paper or "film" refers to a thin amount and certain material types, it will be heated in the oven to high temperature temperature, so that it allows it to extend it to the mold and cool to the shape of the finished product. Its simplified version is vacuum.


      In the simplest form, you can use a small desktop or laboratory size machine to heat the small slice of the plastic board and use a vacuum to stretch it on the mold. This method is usually used for samples and prototypes. In complex and large -scale applications, very large production machines can be used to heat and form plastic boards, and trimmed parts into parts from the cardboard in the continuous high -speed process, and can generate thousands of thousands of thousands per hour according to the machine to generate thousands of thousands of thousands per hour. The size of 10,000 parts and molds and the size of the parts formed.


      Thermoforming is different from the injection molding, blowing plastic, rotating molding and other forms of processing plastic. Thin -warm -up molding is mainly used in one -time cups, containers, lids, trays, foaming, explosive boards and other products in food, containers, lids, trays, foaming, and explosives. The thick -standard thermal formation types include parts such as doors and dashboards, refrigerators, multi -functional lathes and plastic trays.


      Among the most common high -amount methods, the continuous heat formation of plastic boards is to feed a set of index chains containing nails or peaks from rolls or extrusion machines to transport them and transport them to heating to heating To the temperature of the temperature. Then, the heating cardboard is indexed to a formal station. On the site, the mating mold and pressure box are closed on the paper, and then the vacuum is used to remove the trapped air with vacuum. Pull the material into the mold to form a detailed shape of the plastic mold. (In the case of higher and deeper forming parts, inserted auxiliary personnel are usually used in vacuum in order to provide the required material distribution and the thickness of the finished parts. From the vacuum side of the mold to break the vacuum and help the molding part of the mold or leave the mold. The stripping dance board can also be used on the mold, because it opens a more detailed part or a part of the area with a negative bottom cut. . The paper containing the formation of the formation indexes the index to the decoration station on the same computer. On the machine, the mold cuts the part from the remaining paper network into parts, or the index is indexed into a separate decoration board, and The parts formed were trimmed. After trimming into parts, the remaining pieces were usually entangled on the decorative scroll or sent it into the inline particle machine for recycling.


      Most hot -forming companies recover their waste and waste plastic by compressing or eating particle (grinding machine) in the packaging machine and producing ground thin slices in order to sell the company or reorganize in their own facilities. Usually, the waste and waste plastic conversion from the heat forming process is returned to squeezed paper to form again.
