熱成形機とは？

A thermoforming machines, also known as vacuum forming machines, are devices that mold sheets of thermoplastic materials into various shapes. Their primary function is to take heated and plasticized sheets of materials like PVC, PE, PP, PET, and HIPS and, using vacuum suction, shape them into high-end packaging boxes and frames through a mold. This process utilizes a vacuum pump to create suction, allowing the softened plastic sheets to adhere to the mold surface, and after cooling and setting, the desired product shape is achieved. Thermoforming machines are widely used in industries such as plastic packaging, lighting, advertising, and decoration, making them an important part of plastic processing technology.

The working principle of thermoforming machines is based on heating and softening thermoplastic materials. First, plastic sheets are heated until they become pliable, and then they’re suctioned onto the mold surface using vacuum pressure to form the desired shape. This can be accomplished with various types of equipment, including vacuum suction machines, positive pressure machines, and combined pressure machines. These devices can be categorized into single-step and two-step forming machines, depending on the forming method used, to meet different quality requirements for vacuum-formed products.

The applications of thermoforming machines are quite extensive, ranging from small everyday items to large industrial products. For instance, bathtubs and shower trays, car parts, refrigerator liners, plastic storage boxes, and medical device casings are all typical applications of thermoforming machines. This process is widely adopted due to its low cost, high efficiency, and fast production speed.

Overall, thermoforming machines are crucial equipment in plastic processing. They transform thermoplastic materials into various shaped products using heating and vacuum suction principles. Their widespread application across many industries makes them an indispensable part of modern plastic manufacturing.
