Research & Development, Process Engineering, Tooling Design & Manufacturing

Our customers rely on us to provide them with best machinery and tooling for their production needs. We study each machinery project thoroughly, and we look at all machinery, technology and tooling options available to us. If none of these options are perfect for the required task, then we go into R&D mode - striving to turn the seemingly impossible task into a possible task. We are not just machinery suppliers, we are production solutions suppliers; this includes parts production process research & development, tooling engineering, tooling manufacturing and programming. We supply complete turnkey solutions.

Don't Ignore Metal Forming Lubricants

For metal working and metal forming you will need to make sure that you use good quality lubricants.
In your machinery you want to use fluids, oils and coolants which protect and extend tooling life, provide superior surface finishes on the parts you produce, allow faster speeds (cycle times), are easily cleaned up and are safe for the machinery operators.

Going Big in July 2012 - Going Bigger in 2013

On July 3, 2012 we blogged about going big with a DENN CTA-660 CNC tube (cylinder) spinning machine. Now, about 1/2 a year later we go even bigger.
Currently being built is a DENN CTA-720 CNC tube (cylinder) necking-in machine.
This will be the current largest machine in the world for cylinder necking-in operations.
Diameters up to 711 mm (28 inch) and material thickness up to 40 mm (1.57 inch).
Lengths of tubes up to 13,600 mm (44.6 feet).
