How prognosis software can
accelerate R&D programmes
with cost saving potential
Bespoke online tools from EJOT are helping design engineers and developers speed up their research and development programmes by reducing the need for in-house testing, delivering cost savings in the process.
As a specialist in screws for direct fastening in light metal and thermoplastics, EJOT is at the forefront of innovation by helping designers to reduce weight in their assemblies, with the confidence to achieve secure multi-material joining.
The anticipated performance of two of its most advanced fasteners can be forecasted digitally through the use of its custom-designed prognosis software. DELTA CALC® and ALtra CALC® both enable the fastening parameters to be calculated by taking into account the type of materials to be joined and other general design factors.
Their functionality for the pre-calculation of screw joints has already proven to lead to a clear reduction of development time and, thus, significant costs savings in component design. Making accurate calculations early in the design process prevents over-dimensioning of the screw joint and ensures time-consuming and cost-intensive tests on the component are reduced to a minimum.
Similar programs have also been developed by EJOT for its EVO PT® screw, another reliable option for direct fastening into thermoplastics, and FDS®, which joins thin sheet metals made of steel and aluminium to a high standard without the need for a pilot hole.
EJOT® Delta PT
The EJOT DELTA PT® screw is a special fastening element designed for reliable and easy direct assembly into thermoplastics. It has a wide range of application potential and in the automotive industry where the screw is recognised universally as the goto solution. This is largely because this DELTA PT® is designed to accommodate the very high loads which components used in automotive applications often have to withstand.
EJOT® ALtracs PLUS
Similarly advanced is the EJOT ALtracs® Plus screw. This has been developed for the direct fastening into light metal, offering a bespoke self-tapping fastener with maximum strength in light metal joints up to a hardness of 140 HB. Designed for direct assembly into cast holes, the ALtracs® Plus enables significant cost savings to be realised compared to metric screws through its ability to reduce the number of work steps, such as thread cutting.
“Our prognosis software for DELTA PT®, EVO PT®, ALtracs® Plus and FDS® screws provides a valuable resource for design engineers as they seek to innovate and achieve a secure joint in ever more complex designs. As light metals and thermoplastics are increasingly being regarded as routine material choices in applications that achieve weight reduction goals, it is important to know the parameters of the fasteners at an early stage, which is exactly what our software tools will provide.”

Design engineers can register to use EJOT’s bespoke prognosis software free of charge, along with accessing a wide range of other services such as CAD data and product information HERE
A ‘light version’ of DELTA CALC® and ALtra CALC® can be accessed directly online, providing 24/7 access in a user-friendly format that is optimised for independent use. For highly complex applications that might not be covered by the light version, access can be provided by EJOT application engineers and of the APPLITEC laboratory.
