Spring calculator for professionals

WTI invests in dyeing technology WTI prides itself on adapting to new trends and developments within the fastenings market, and has invested in a new machine to keep up with the increasing demand for dyed inserts. The Rotamat R60 is an innovative coating system that allows the company to colour its inserts with optimum control and e ciency, with the fully automatic spraying system and rotating drum ensuring a uniform dye coating. to colour small components, the easily exchangeable drum sizes enable WTI to colour a variety of insert sizes in a range of quantities, meaning it can quickly adapt to customer needs. The process is further streamlined due to the Rotamat’s sensitive IR sensors, which carefully monitor and adjust the temperature of heated inserts to allow them to dry during the colouring process. This removes the need for further treatment, so WTI can despatch dyed inserts faster than before. With repeatable, visually homo- geneous results, the new machine enables WTI to provide dyed inserts to high quality standards in low lead times, allowing WTI to meet the increasing industrial demand for coloured inserts as a means of identi cation.

▲ Spring Calculator Professional software from the Institute of Spring Technology

Integral to the Institute of Spring Technology (IST) is the design, production, consultation and accreditation process within the spring industry. To assist this, IST has developed software, Spring Calculator Professional (or SCP for short), that facilitates and simpli es the creation of even the most challenging spring designs. SCP has continued to evolve since its creation in 1988, and is widely recognised by industry professionals. The software allows designers to create designs and validation work throughout the whole of the project, for a range of spring types. Spring Calculator Professional is user-friendly software that allows spring characteristics to be evaluated. The user can make changes to materials, design standards and spring parameters, which are quickly and automatically assessed. The designer gets a clear overview of a spring that is t for purpose with the assurance of correct design. Using the software aids the entire design process, saves time and reduces human errors. The life of the designed spring at various operating positions can be predicted using fatigue and relaxation data based on the Institute of Spring Technology’s own research, drawn from many years of experience and testing. Other key features included in the SCP software are that it provides Goodman diagrams, load/length, and other graphical tools to help evaluate the design. In addition, there are options to allow a design to be optimised to fit in with “real-world constraints” such as limited space for the spring when it is integrated into equipment. Graphical and test-based data are available, including engineering drawings. Spring design drawing documentation can be customised with a company name and logo, which adds to the professionalism of design projects. Choosing to use SCP design software can ensure that the spring is designed with the exact and correct tolerances, therefore preventing unnecessary failures. The Institute of Spring Technology has complete con dence in its Spring Calculator Professional software – made by the professionals for professionals. Institute of Spring Technology www.ist.org.uk
