A method of manufacturing open shell products using thermoplastic sheets. The plastic sheet is cut to a certain size for heating and softening, and with the help of the air pressure difference or mechanical pressure on both sides of the sheet, it is deformed and then overlaid on the specific mold contour surface, cooled and shaped, and the cutting edges are trimmed.
Due to the low pressure, the complex mold structure and expensive mold materials are not required, so the mold cost is low, the part cost is very competitive, and it is an ideal process for large part samples and small batch production.
Two-sheet thermoforming uses two sheets, making it possible to produce a double-sided hollow box part with features on both sides.
Double sheet thermoforming expands the application of hot compression molding, and in some cases can replace rotational and blow molding to produce hollow box parts.
Thermoforming is a manufacturing process that involves heating a sheet of plastic or other material until it is pliable, then forming it into a specific shape using a mold or template. The equipment used for thermoforming typically includes:
A thermoforming machine, which is the main piece of equipment used in the process. This machine typically consists of an oven for heating the material, a forming station where the material is shaped, and a trimming station where any excess material is removed.
A mold or template, which is used to shape the material into the desired form. This can be a simple, flat mold for basic shapes, or a more complex, three-dimensional mold for more intricate designs.
A vacuum pump, which is used to create a vacuum inside the mold to help pull the material into the desired shape.
A cooling system, which is used to rapidly cool the formed part to maintain its shape.
Material handling equipment, such as conveyor belts or robots, which is used to move the material through the various stages of the thermoforming process.
In addition to these core pieces of equipment, thermoforming operations may also require other auxiliary equipment, such as mixers for blending materials, grinders for reducing material to the proper size, and ovens for preheating the material.
Also known as vacuum forming machines, these machines heat plastic sheets until they are malleable, and then use vacuum to mold the plastic into molds. Once the plastic is formed and cooled, a stream of air separates it from the mold. Thermoforming machines are best suited for easy-to-form plastics such as ABS, polystyrene and PETG.
Dual sheet thermoforming is a specialized type of thermoforming in which two sheets of material are used to produce a part. In this process, two sheets of material are heated until they are pliable, then placed into a mold where they are formed using a combination of pressure and vacuum. The two sheets are then bonded together, creating a part that is composed of two layers of material.
Sheet forming is a manufacturing process that involves shaping a sheet of material, such as metal, plastic, or composite, into a specific shape. This process can be performed using a variety of techniques, including bending, stretching, or drawing the material.
