what is Thermoforming Process in CEX

Thermoforming Process is a molding method in which a thermoplastic sheet is heated to soften and becomes a product under gas pressure, liquid pressure or mechanical pressure using appropriate molds or fixtures.

CEX is a specialist manufacturer in the field of plastic thermoforming.

We offer a wide range of thermoforming plastic solutions for various industries such as food packaging, medical equipment, automotive parts, electronic components, aerospace, medical, and consumer goods.

plastic thermoforming types

There are three main types of thermoforming: vacuum forming, pressure forming, and twin-sheet thermoforming.

Each of these processes has unique advantages and is suitable for different applications.

Vacuum Forming

Vacuum forming is the most common type of thermoforming.

The process involves heating a thermoplastic sheet until it becomes soft and then placing it over a mold. A vacuum is then applied to the mold, which pulls the sheet into the mold’s shape. The excess material is trimmed, and the finished product is removed from the mold.

Vacuum forming is ideal for producing large, flat parts such as trays, packaging, and signage.

Pressure Forming

Pressure forming is a type of thermoforming that uses additional pressure to create more detailed and precise parts.

The process involves heating the thermoplastic sheet until it becomes soft and then placing it over a mold. A mechanical press applies pressure to the sheet, which is then forced into the mold.

Pressure forming is ideal for producing parts with complex geometries, tight tolerances, and fine details.

Twin-Sheet Thermoforming

Twin-sheet thermoforming involves two separate sheets of plastic that are heated and formed simultaneously.

The process involves heating both sheets of thermoplastic material and then placing them in a mold. The sheets are then fused together, forming a hollow product.

Twin-sheet thermoforming is ideal for producing large, hollow products such as tanks and containers.

At CEX, we have a wealth of experience in the field of thermoforming. Our team of experts can work closely with customers to understand their design requirements, industry standards, and production goals. We can help customers evaluate the advantages and limitations of each type of thermoforming process and provide guidance on the most suitable method for their project.

plastic thermoforming machine

The most common machine used in plastic thermoforming include:

Vacuum forming machine

A machine that uses vacuum pressure to shape the plastic sheets around a mold.

Pressure forming machine

A machine that uses pressure and heat to create complex and precise plastic products.

CNC machining center

A machine that uses computer-controlled technology to cut and shape plastic sheets with high accuracy.

Extrusion machine

A machine that melts and forms plastic pellets into continuous sheets for further thermoforming.

Cutting machine

A machine that uses blades or lasers to cut plastic sheets into the desired shape and size

Material Used For Thermoforming Process

Thermoforming is particularly suitable for the manufacture of products with thin walls and large surface areas.

Commonly used plastic varieties are various types of polystyrene, plexiglass, polyvinyl chloride, ABS, polyethylene, polypropylene, polyamide, polycarbonate and polyethylene terephthalate.
