FlowControl+ passes test stage with flying colours
|
Presented as a world's first at the K show and highly acclaimed by the specialist audience there, the patent
pending FlowControl+ nozzle technology from the company DESMA has now come
through the hands-on baptism of fire.
The actively controlled injection nozzle technology that optimizes cure times intelligently fully met the high
expectations during the test stage over several months both at the customers' and in the in-house process
engineering center.
"The trials on site at the customer ran well, the expected cure time reductions were completely confirmed and the
software-supported temperature control works impeccably", sums up the satisfied head of development, Volker Krell.
In the meantime the serial production has been started at the first user of the FlowControl+-technology
- a seal manufacturer who has already reordered another three machines. Simultaneously the first machine equipped with
FlowControl+ was delivered particularly for large-sized and thick-walled parts.
Goal of the in-house trial series is to test and optimize all possible fields of use. To this end, the most various
applications for customers from totally different industries are scrutinized in the DESMA process engineering center.
The test engineers avail themselves of the respective original customer mould enabling them to work under real conditions.
The secret of this technology that saves more than 30 % of cure times is the actively controllable injection nozzle to
reduce cure time dynamically depending on the article wall thickness. It allows to variably adjust the injection gap
during the injection process with a tolerance of less than 0,1 mm and thus to control the shear heat input highly
precisely. Even with production stops, there is no risk of material being pre-crosslinked. Specifically for high-viscosity
compounds and liquid silicone applications DESMA developed an extremely robust shut-off nozzle function.
