Precision cold forming and engineering firm Dawson Shanahan has released a white paper on cold forming that could help manufacturers discover ways in which to achieve faster lead times and better surface finishes with a wide range of materials while also cutting costs and waste.
The paper explains why cold forming – the extrusion of a part from a blank – is a fast, economical way to produce robust, complex components as well as the simple, high volume components with which it is historically associated. The process is capable of delivering precision engineered parts with up to 80% less scrap than machine processes, offering an attractive process option for any component manufacturer in the current economic climate.
The white paper goes on to discuss such topics as stress deformation, mechanical integrity and dimensional tolerances to give a deeper technical understanding of the benefits of cold forming before highlighting some of Dawson Shanahan’s recent innovations, including a revolutionary needle-free syringe and a container for the purpose of holding nitrogen gas over long periods without leakage, both of which were achieved by cold forming aluminium to high levels of specification.
The paper concludes by discussing how the research and development of cold forming has increasingly shifted from ‘experience-based’ development to computer-aided research, and the significant ecological benefits of the process compared to alternatives such as hot forging, where the high level of heat, and thus energy, required comes at a price to the environment.
