Maintenance station NoWOPEN

Air-bearing maintenance station for safe opening, testing and mounting of tools

Tool maintenance simplified

Reduce avoidable downtime
Unsafe tool handling, poor and unergonomic access to tools, and unnecessary rebuilding or repair work are common problems in tool maintenance and often lead to avoidable downtime.
With the help of the NoWOPEN maintenance station, this is a thing of the past. The air-bearing moving platen, which functions similarly to an air cushion, allows the mold halves to be opened and closed quickly and safely.
In addition, further functional checks and numerous tests can be performed on the mold via the built-in hydraulic power unit and the optionally available leak-testing.
This shortens assembly and maintenance times and consequently significantly reduces machine downtime during mold maintenance.

handling

Move heavy mold plates without effort
After the mold is set down on the table, the mold fixing platens are connected to the table platens on both sides by clamping claws. When compressed air is applied, a kind of air cushion is created on the underside of the moving platen, while the other side remains firmly connected to the table. Thus, the mold can be easily opened and divided into both halves of the mold by sliding movements without much muscle power.
The service station includes a built-in hydraulic power unit. The hydraulic pump and a height-adjustable piston can be used to test the mold's ejector assembly by extending and retracting it. The additional free hydraulic connection enables further mold tests with which slide systems, core pulls, valve gate nozzles and hydraulic cylinders can be checked for function.
With the optionally available leakage test kit, the mold's temperature control channels can be tested for leaks using compressed air. In this way, possible leaks due to pressure loss at the pressure gauge are detected at an early stage.
