To achieve this, we use cutting-edge technologies to ensure exceptional results. Some of our key processes include:

Vacuum Forming

This process involves heating a plastic sheet and then applying vacuum so that it conforms to the mold using atmospheric pressure. It is an ideal technique for producing parts with simple to moderately complex geometries, offering excellent detail and precision.

Positive Pressure Thermoforming

In this method, air pressure is applied to the plastic sheet, forcing it to take the shape of the mold. It is particularly useful for producing more complex parts with sharper and more pronounced geometries.

Thermoforming with Vacuum Assistance

Also known as vacuum molding, this process combines the advantages of both vacuum and pressure forming. Vacuum and air pressure are applied simultaneously to produce parts with more complex geometries and precise details.

Frequently Asked Questions About Thermoforming

Thermoforming is a manufacturing process that involves heating a plastic sheet until it becomes flexible, then shaping it over a mold using vacuum suction or pressure to achieve the desired form.
Thermoforming is used in various industries such as automotive, packaging, electronics, and medical equipment for the manufacturing of customized components and products.

Among the most commonly used materials are ABS, polycarbonate, polystyrene, polyethylene, polypropylene, acrylic (PMMA), and PET.

Thermoforming uses a plastic sheet that is heated and shaped over a mold, whereas injection molding involves injecting molten plastic into a closed mold. Thermoforming is generally more suitable for large parts and low to medium production volumes, offering lower tooling costs and shorter lead times compared to injection molding.

It offers lower tooling costs, faster development times, design flexibility, and the ability to produce large, thin-walled parts.
The most common types are vacuum forming, pressure forming, and mechanical forming.

It is a technique in which a heated plastic sheet is placed over a mold and vacuum suction is applied to make it adhere and take the shape of the mold.

Thermoforming machines are used, which can be automatic, semi-automatic, or manual, depending on the required production level.

Although often used interchangeably, the term “thermoconforming” typically refers to shaping materials using heat and pressure in a mold, while “thermoforming” is more broadly used to describe the general process of shaping plastics through heat.

It is used to manufacture housings, signage, lighting components, and other products that require high transparency and durability.

It is a piece of equipment or machine used in the thermoforming process to heat and shape plastic materials.

They are tools used to shape the heated plastic material. They can be made of metal, wood, or resin, depending on the type of product to be manufactured.

The design of a thermoforming mold must take into account the geometry of the final product, the type of material to be used, and the required dimensional tolerances. A well-designed mold ensures consistent material distribution, accurate forming, and high-quality finished parts.

Proper mold design is essential to avoid defects, ensure repeatability, and optimize the thermoforming process for performance and efficiency.

acuum thermoforming is a process in which a plastic sheet is heated until it becomes soft and then placed over a mold. A vacuum is applied, pulling the sheet tightly against the mold surface to create the desired shape. Once cooled, the formed part is trimmed and finished. This technique is commonly used to produce packaging trays, panels, enclosures, and other parts with simple to moderately complex geometries. It is cost-effective and well-suited for low to medium production volumes.

In vacuum forming, suction is used to adapt the material to the mold, while in pressure forming, additional pressure is applied to the material to ensure it conforms perfectly to the mold.

FAQs About Thermoforming

hermoforming is a manufacturing process in which a plastic sheet is heated until it becomes pliable, then shaped over a mold using vacuum, pressure, or mechanical force. Once formed, the part is cooled and trimmed to achieve its final shape. This process is widely used to produce lightweight, durable, and cost-effective plastic components for industries such as automotive, medical, packaging, and consumer products.
It is used in the manufacturing of packaging, trays, housings, automotive parts, and consumer products.
The most commonly used materials are ABS, PET, polystyrene, polycarbonate, polyethylene, polypropylene, and PVC.

A thermoformer is a machine used in the thermoforming process to heat plastic sheets until they become pliable and then shape them over a mold using vacuum, pressure, or mechanical assistance. Once formed, the plastic part is cooled and trimmed to its final shape.

Thermoforming machines can be manual, semi-automatic, or fully automatic, depending on production needs. They are essential for manufacturing a wide range of products such as packaging, automotive components, and consumer goods.

Although the terms are sometimes used interchangeably, a thermoformer generally refers to a machine used for the thermoforming process focused on producing thin-walled packaging and similar products, while a thermoconformer may refer to equipment used for more specific and varied forming processes.

There are automatic, semi-automatic, and manual thermoforming machines, as well as specialized equipment for vacuum and pressure forming processes.

It is the process in which a plastic sheet is heated until it becomes malleable and then shaped over a mold to form the desired geometry.
It is used to manufacture interior and exterior components such as door panels, dashboards, and linings.

They are tools used to shape the heated plastic sheet during the thermoforming process.

It is the process of shaping ABS (Acrylonitrile Butadiene Styrene) sheets using heat to produce strong and durable products.

It consists of molding PET (Polyethylene Terephthalate) sheets using heat, commonly used to manufacture food containers and trays.

It is the process of shaping polycarbonate sheets using heat, commonly used in the manufacturing of products that require high impact resistance and optical clarity.

The main types are vacuum forming, pressure forming, and mechanical forming.

It is a high-capacity machine used for large-scale production of thermoformed parts for industrial applications.

It is a technique in which, in addition to vacuum, pressure is applied to the plastic sheet to ensure it conforms perfectly to the mold.
