Process Control

The user interface of Wollin controls is tailored to the spraying application.
The intuitive operating concept allows you to create spraying programs with predefined commands without programming knowledge. The easy learnability and the same user interfaces for spraying machines, metal dosing systems, release agent supply systems and gantries enable the user to achieve better results in a short time. 

The display of process data, as well as the integrated Industry 4.0 capabilities allow networking with the die casting machine, as well as external access via remote maintenance (if requested).

Wollin controllers and operator panels are designed to withstand the rigors of everyday foundry use.

MDA 20/25/40/60/65/100

For fully automated conditioning and transporting of release agents to die spraying machine. 

The mixing unit produces the mixture (concentrate with water) only when needed so that fresh emulsion is available at all times. No longer is cumbersome mixing required and the stagnant, partially segregated emulsions that were formed long before application are eliminated.
