Cold-forming is a tried-and-true manufacturing process. Not only does it promise efficiency and good quality at a low cost, but cold-forming also ensures low carbon emissions. We’ve been cold-forming at Optimas for more than 90 years, and we were proud to receive our EMS (Environmental Management System) Registration Certificate in 2020.
What is Cold Form Manufacturing?
Cold-form manufacturing is a production method that involves forming metal into different shapes through force, and without heat. The metal is processed by a heading machine, and is moulded into a fastener using dies. The part is then fine-tuned by roll threading, pointing, shaving, trimming and quality processing to form the final product.
Cold-form manufacturing is typically used to make fasteners, complex shapes and screw heads. Depending on the geometry and material used, an experienced cold-form manufacturer can work as accurately as within a thousandth of an inch. Cold-forming handles parts from 2mm to 48mm in diameter and in lengths of over 300mm, all while ensuring a low carbon footprint.
How is it sustainable?
Over the last couple of years, businesses in the manufacturing industry have prioritised environmental sustainability, with a particular emphasis on ‘going green’. Cold-form manufacturing is a key way to guarantee eco-friendly production, by ensuring no waste of raw materials. A part is formed in its near-net state, thus avoiding any excessive use of machines. Here at Optimas, 89% excess material left over after trimming or shaving is recycled, with 0% sent to landfill. It’s never been more crucial to look after our natural resources, and cold-forming ensures responsible and sustainable manufacturing practices.
What are the other benefits of Cold Form Manufacturing?
1. Cost Reductions
As cold-forming avoids wasting both energy and raw materials, it reduces the cost of the overall production process.
2. Speed and Efficiency
Cold-forming is a fast process. Simple parts can be produced at a rate of 300 per minute, and more complex parts generated at 200 per minute.
3. Strength and Durability
Cold-forming maximises a part’s metallurgical properties, prioritising strength and durability by ensuring its structural integrity.
4. Large Scale Production
The speed of cold-forming manufacturing means you can produce hundreds of millions of parts a year, allowing an efficient handling of full-scale production and high-demand periods.
Choosing a Cold-Form Manufacturer
Cold-forming evidently requires specialist equipment, and you’ll want to work with a manufacturer that can understand your specific requirements. Here at Optimas, we have extensive experience in cold-form manufacturing, and we’ll offer you the opportunity to work with our engineering team during the design process. 100% of Optimas’ UK facilities are powered by renewable energy, and onshoring will significantly reduce your carbon footprint. Consider working with us to help you source sustainably and maximise product quality.
