White paper demonstrates benefits of cold forming
Precision cold forming and engineering firm Dawson Shanahan has released a white paper on cold forming that it hopes could help manufacturers discover ways in which to cut lead times, achieve better surface finishes and cut costs for parts made from a wide range of materials.
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.
The process is capable of delivering precision engineered parts with up to 80% less scrap than machining processes, which, says the company, offers 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.
