CNC Machining - Thermoformed Products
Plastic Machining with CMS' Innovative CNC Solutions
CMS North America (CMSNA) manufactures a full line of CNC plastic machining centers engineered to deliver the fastest, most efficient, and most versatile performance possible. Our advanced CNC systems provide a broad range of machining capabilities alongside high speed processing and numerous automated functions.
There are countless types of plastics available, making it one of the most widely used materials in the world. Plastics are generally less expensive than metals, and many varieties offer comparable strength with significantly lighter weight. Commonly machined plastics include polypropylene, PVC, acrylic, vinyl, nylon, ABS, Torlon, Ultem, and Nomex.
Plastic materials are used to manufacture a vast range of products, from small components for automobiles and food processing equipment to large pieces for building construction and countless others in between.

Plastic—Fast, Flexible, Waterjet cutting
Waterjet cutting is an ideal technology for cutting thermoformed plastics. As an industrial tool it's capable of cutting a wide variety of materials using a very high-pressure jet of water—or a mixture of water with an abrasive substance. In the case of thermoformed plastics, most often the trimming work can be accomplished as just a "pure" water application.
Waterjet cutting can be accomplished as part of a CNC machining center with capabilities using up to 5 axis IKC (Intelligent Kerf Cutting) or with multiple heads—for high volume production—or exploited as an "end-effector" in a robotic application.
Whatever the situation, waterjet cutting can be a real alternative to trimming by machining with a "routing" tool, especially where:
- openings are small and difficult to reach
- the width of the trim line is a concern
- holding the part is problematic
Plastic materials, including advanced engineering plastics, are very easy to process with the use of the right equipment. Plastic is readily cut, drilled, milled, and otherwise machined. However, because of the varying physical characteristics of different types of plastic, certain factors must be accounted for.
Plastics are comparatively much softer than metals, as well as having greater elasticity. These properties can make it difficult to maintain tight tolerances during and after machining.
Plastics also have much lower softening/melting temperatures and greater thermal expansion rates than metals. A mist or full-flood cutting system can be used to reduce the heat generated in machining and minimize the effects of high temperatures.
Machining plastic can produce a large amount of dust and swarf. A full-flood cutting system, or one with dust extraction capabilities, can help eliminate particles from the machining environment.
Physical/Chemical Properties of Plastics
Plastic materials may be made from synthetic, semi-synthetic, or natural materials. Most plastics are manufactured from petrochemicals, but plastics made from plant materials (called bioplastics) are increasingly common.
Because there are so many different types of plastic, the physical properties of the material can vary considerably. Hardness, density, and resistance to heat, solvents, oxidation, and other factors are affected by the organic chemistry of the polymer.
