Cold-Forming Technology

MW Components engineering and manufacturing experts use state-of-the-art machinery and up-to-date technology-driven processes to produce precise components for critical applications. One example of our process capabilities includes cold-forming, also referred to as cold-heading or roll-forming technology. Ideal for small metal parts manufacturing and other components, cold forming is a specialty process that can significantly improve outcomes for businesses in a variety of industries.

Cold-Forming Overview

Cold-forming or cold-heading is the application of force with a punch to a metal blank staged in a die.

The force exceeds the alloy’s elastic limit, causing plastic flow until the metal blank assumes the shape bound by the punch and the die. As the name implies, this method of metal part forming is achieved by force alone, forgoing the application of additional heat or cutting and shearing.

When machining a part, the grain flow of the material is interrupted as the original material is removed to form the part. Through the cold heading process, all original material is used causing a restructuring of the material grain as the part is formed. This results in improved tensile strength as compared to manufacturing techniques.

Open Die Cold Forming

Cold forming creates favorable strain (work) hardening. With open die cold forming, the metal is placed between two flat dies and compressed until the shape is revealed. MW produces cold formed bolts and cold formed nuts as well as other products using this technology. Our proficiency in open die cold formed fasteners allows us to provide answers to complex needs, including solutions for difficult spaces and innovative applications.

Open Die Cold Forming Capabilities

  • Long length, small diameter fasteners
  • Exceptional straightness in long parts
  • Straight, long parts in high volumes
  • Complete automation for accuracy and repeatability at lower costs
  • Cost reduction by replacing high-cost machining and multiple parts

Typical Applications

Many types of parts can be produced using cold-heading technology, including fasteners, screws, nuts, bolts, electrical contacts, and rivets. This manufacturing process is ideal for small metal parts, including micro electronic components, micro contacts, micro grommets, glass and metal seal manufacturing, and other small component manufacturing.

Additionally, the following project types generally benefit from cold-headed / cold-forming manufacturing:

  • Mission-critical applications
  • High volume requirements
  • Correction of part failures
  • High material strength requirements
  • Tight tolerances and critical specs

Many shapes and part configurations can be produced using cold-heading technology-- some examples include threads, knurls, heads, chamfers, grooves, tapers, and undercuts.

Required features which cannot be produced through standard cold-heading processes can be achieved by utilizing secondary procedures such as rolling, threading, pointing, bending, or annealing.
