HYDEN 8 color High-speed Dry-Offset Presses

M-8400M Signature Series

The Hyden M-8400M is the most advanced Dry Offset press offered for the decoration of disposable plastics containers. This press has been designed for offering a vivid decoration on the containers and has features that allow high quality vignettes and half-tones to be printed on disposable containers.

The press features water-cooled rollers to maintain ink viscosity. Dual form rollers deliver ink precisely to the printing plates. Precise adjustment of the form roller and plate cylinder contact pressures makes it possible to set-up the press for fine results. The ink flow can be adjusted precisely through the machine control and the ink ducts are equipped with automatic agitation systems for precise ink delivery.

The print cylinders feature a precision Pin-Bar mounting system that allows for 'First time make-ready' greatly reducing the time required for plate mounting and color registration. This allows complex jobs to be registered and set up quickly. The ink-heads feature automatic wash-up for quick color changes. A Video Punching unit is provided with the machine for accurately punching the printing plates with reference to their registration marks

The print cylinders have an On The Fly Registration feature that allows registration changes to be carried out in a running machine without the need to stop the press for registration changes. This is also called a Running Register feature.

Cup to printing blanket pressure is precisely adjustable electronically through a single-axis Servo controlled slide also featuring mandrel position memory for quick engage and disengage with the blanket and automatic return to the set contact position.

A stack buffer with logic controlled stepping drops stacks of un-printed containers into the press. A Servo driven auto-loader with 4 progressive pitch screws separates the stack and feeds the cups onto printing mandrels that are driven and synchronized with the blanket drum. The printing mandrels also rotate at the UV irradiator and mandrel rotation is monitored by the control system that gives an alarm if any of the mandrels do not rotate sufficiently during irradiation. No-cup No-Print and Double-Cup Shut-Down are standard functions.

The press features a compact UV OMC system that cures printed cups and the irradiator radiation is automatically blocked during UV stand-by.

After printing and curing the re-stacking unit of the press automatically stacks printed cups of pre-determined count and ejects them onto a collection tray for packing

The HYDEN M-8400M press is equipped with the TESLA Controls 8400 ServoCAT control system that manages all the press and auxiliary functions

Individual control has been provided for the print drum, indexing unit and the feeding unit that assists in the make-ready of the press. In operation, all units synchronize and run in precise sync
