Optimize postforming with high-precision BERMAQ CNC milling machines

The final touch that makes the difference.

The thermoforming industry is experiencing rapid growth, driven by sectors as diverse as packaging, healthcare, automotive, and marine. Despite their differences, all share a fundamental technical requirement: precise, fast, and repeatable processes that ensure high quality and productive efficiency.

In this context, BERMAQ CNC milling machines —especially the LINK model— are the ideal solution not only to successfully complete the postforming process but also to machine the molds on which the parts are shaped, ensuring quality from the start.

Thermoforming: when molding is not enough

Thermoforming involves heating plastic sheets until they become elastic and malleable, then adapting them to a mold using vacuum or pressure. However, the resulting parts require a finishing process to achieve the tolerances, functional shapes, and details needed for their final application.

BERMAQ’s role in precision postforming

BERMAQ 5-axis CNC milling machines allow high-speed machining with maximum dimensional accuracy for all types of thermoformed parts. This automated process guarantees an impeccable final result, even for long series or complex parts.

• Perimeter trimming: removing excess edges to define the final contour of the part accurately.

• Internal contour milling: opening windows, slots, pockets, or access points for electrical, mechanical, or purely aesthetic and/or functional purposes.

• Drilling and countersinking: integrating fasteners, assemblies, or inserted elements.

• Thickness reduction (roughing): adjusting thickness in specific areas for design or weight reasons.

• Chamfering and rounding: improving the aesthetic finish and safety of the final product.

From mold to finished part: total process control

CNC milling machines are not only used to finish thermoformed parts but also play a key role in manufacturing the molds themselves. Thanks to their high precision and ability to work with a wide variety of materials —such as aluminum, technical resins, composites, wood— they allow machining complex molds with great detail and dimensional accuracy. This ensures that the thermoforming process is carried out on a reliable base, optimizing both part quality and production cycle efficiency.

With a range of machinery designed to offer maximum precision, versatility, and performance, BERMAQ has established itself as a benchmark in machining solutions for demanding sectors such as aerospace, technical plastics, automotive, and the aluminum industry. Thanks to its advanced technology, its machines enable everything from the most complex perimeter trimming to high-precision machining of thermoformed parts, composites, or light metals. BERMAQ’s commitment to continuous innovation and specialized technical support ensures its clients not only achieve optimal results but also gain a clear competitive advantage in their production processes.
