BENDINGAt Coltwell Industries we have a variety of bending processes, enabling us to provide high quality bent parts at the lowest cost to customers. From one piece to 1, 000 pieces no quantity is too large or too small for the bending process. Mandrel bending is also available for tight CLR (centerline radius) bending requirements. Our bent tubes are used in everything from general purpose handles to specialized medical, dental, and surgical tubular parts. Our representatives and engineers will work to ensure that Coltwell Industries high quality standards are met on each and every part. Contact Coltwell today for all of your bending needs!

Coltwell's Italian division specializes in the cold forming of fasteners from any kind of stainless or carbon steel, as well as a variety of other metals upon request. The standard production is compliant with UNI-DIN-BSW norms and American Standards. New production technology allows us to produce items with extreme length. Standard items at lengths up to 3, 000mm and up to 6, 000mm available upon special request. From standard to customized parts our production flexibility allows for quality manufacturing with out quantity limitations. Contact Coltwell today for all of your standard and customized requests.

From concept design to a finished, ready-to-assemble part, Coltwells fabrication capabilities will help you enhance your product, while enabling you to bring it to market faster, improve overall quality, and reduce costs. From punching, drilling, and other standard fabrication capabilities to world class close tolerance technology and sophisticated, custom-built, dedicated machining centers, we have the fabrication knowledge and tools to transform your extruded aluminum into integral precisely extruded components.

With a large variety of presses available for production Coltwell offers aluminum extrusions in a variety of alloys. Most alloys are available in both hollow and solid shapes:

Coltwell Industries produces highly intricate miniature extrusions to the most exacting tolerance. While offering a variety of tight tolerance miniature extrusions in their standard shapes Coltwell also has the ability to custom manufacture miniature shapes to meet customers specific requirements.

In addition to standard profiles, we also produce custom shapes that have been specifically designed by our customers for their own product. Enclosures, heat sinks, telescoping tubes, trim molding, lighting fixtures and odd shaped hollows and solids are examples of custom profiles manufactured by Coltwell for our customers. We produce profiles which range in size from mini up to large circle size. To find your circle size, determine the diameter of the smallest circle that will entirely enclose the cross-section of your part. This will be the profile's circle size. Our profiles are available in many hard and soft alloys such as 1000, 2000, 3000, 5000, 6000, 7000 series alloys in various tempers. Aluminum alloys are selected for their unique characteristics including strength, corrosive resistance, machining and versatility. In conjunction with our aluminum profiles, we offer as an additional service to our customers if their product requires it, injection molded plastic components to complement the product. This service provides our customers with the comfort of a finished product with sole source responsibility. Good multi-purpose alloys are found in the 6000 series. The 5000 series offers strong welding characteristics and corrosion resistance in a marine environment. Alloy series 2000 and 7000 are high in strength and widely used in the aircraft industry. The 1000 series is better than 99% pure aluminum and has several applications typically in the electrical and chemical fields. Our profiles are available in several types of finishes. In addition, secondary fabrication is also available to our customers. Prior to designing your profile you should consider the function of the product, the tolerances required, the surface finish and the alloy. Often times, a standard shape can be utilized rather than a custom shape by making slight modifications to your product.
