Complex cold-formed parts
Why do you need complex parts?
How does it work?
Screws with complex geometries are far more than just simple fasteners; they are engineered components critical to industries like automotive, electronics, medical just to mention a few. The ability to customize their design and material properties enables innovation and improvement in performance, safety, and precision. Understanding the role of complex geometries in screws is essential for anyone involved in industries where these fasteners are used.
Some examples of complex parts include shoulder screws, large cylinder-shaped drilled heads, or large head to shank ratio screws.
In some cases, the parts may require secondary operations to achieve the desired final shape and functionality. These operations include adding captive washers, rubber gaskets and caps, creating drill holes, clearance grooves, or undercuts, or applying special product finishing like sealing or adhesives.
These parts are produced by cold heading technology in multi-die forming, forming shapes without causing scrap material and allowing complex parts to be manufactured at high production rates. Our CNC and assembly machines enable us to perform secondary operations.
Complex parts are developed to adapt to the specific needs of our customers’ applications and are manufactured according to project requirements. Being involved in the early stage of the project allows for great opportunities to reduce costs and optimize assembly lines:
- Reduction of scrap material in comparison to traditional screw machining.
- Allows multi-piece to be manufactured as a single part.
Enhanced Functionality: Complex geometries enable screws to provide enhanced functionality. Threads, heads, and shanks can be meticulously designed to meet specific application requirements, ensuring optimal performance.
Innovative Solutions: Special screw designs are at the forefront of innovation in various industries. They address challenges that standard screws cannot, leading to breakthroughs in areas like electronics, robotics, and medical devices.
