Thermoforming is the process of heating a piece of plastic into a softer form.It is then put into the mold in order to shape it into the desired shape.Then trim the plastic around the form to create the available plastic product.The plastic film is then heated at high temperature enough to stretch to the pre-made metal mold and cool to the shape of the mold on it.This method is different from injection molding or blow molding because it involves thin and flat plastic products rather than single solid forms such as nuts, bolts and non-hollow parts.Thin-Instrument thermoforming is mainly used for lighter plastic products such as plastic cups, containers and covers.Thick-The instrument thermoforming can be used to make plastic parts of the car, such as the door and dashboard inside the car.The most common way to make thinThe meter product is to combine the pins that pierce the plastic sheet by feeding the plastic sheet into a set of index chains.The plate is then heated through the oven to the molding temperature.Once passed, the paper was moved to a table station where the matching mold and pressure box were closed on the paper.Then a vacuum is applied to remove any air in the mold, while pulling the plastic material onto the mold, forming the plastic sheet into the shape of the mold.After that, the reverse vacuum forces the molded parts of the plastic out of the mold.The plastic sheet is then moved to the trimming station where the rest of the plastic is formed and cut from the rest.The thermoformed plastic trimmed from the molded part is collected by the pick-upReel to be recycled or online granulator.Thermoforming companies usually recycle waste plastics from the manufacturing process.This is done by compressing them into granulators that grind them into plastic flakes.These flakes are either sold or reused during manufacturing.There are different kinds of hot forming molds: wood grain, machined aluminum molds, cast aluminum molds and composite molds.Wood patterns are usually used in the first stage of thermoforming.The machined aluminum mold is cut from the solid aluminum block, while the cast aluminum mold is cast in the foundry.The composite mold is made of filled resin and is a lowThe cost of replacing mechanical processing or casting aluminum molds.Thermoforming is a $10 billion industry in the United States, of which 25% are made from thick-Made up of thin plastic and 75%gauge.Many of these companies cater to custom plastic molding.
