Effective rapid prototype fastener concept
With its Fastener Express method, for the first time Arnold Umformtechnik offers designers an end-to-end concept that allows highly complex fastener components and precision parts to be developed quickly as prototypes and manufactured later as production-ready parts with the same technical properties and cost-effectiveness for large volume production. This would be of particular benefit to the automotive industry, for example, where development departments would previously have had to reckon on development times of up to 30 weeks for special solutions in this area.
As early as the development phase, Arnold's Fastener Express team carries out the 'Production Ready' check to determine whether the subsequent production-ready part will be a turned part or a moulded part. This decision has major ramifications in terms of potential cost savings. Many turned parts can be converted to more economical moulded parts during the transition from the prototype phase to volume production.
A specially formed rapid prototyping team eliminates the lost time that usually arises from administrative processes. The established 'Direct Acceptance' process systematically eliminates request delay times typical in the industry. Instead of a wait for handling, order receipt automatically triggers a prompt technical evaluation of factors such as using typical fastener materials or testing the mechanical properties of the joint.
Additional time savings with the Arnold method arise from the simultaneous transformation of 3D CAD data into physical products. The time-consuming steps of tooling design and tooling procurement are entirely eliminated. Blanks go directly to machining, where they are turned as production-ready parts and sent to finishing. A wide variety of finishing options are available in-house, including heat treatment and electroplating, making time-consuming and costly liaison with external service providers unnecessary.
