AUTOMATIC SHEET FED PRESSES UP TO B1

 The machines we choose to convert or rebuild have been selected as a result of our many years experience in working with print machines. They are very well-built, durable machines manufactured to a high standard of engineering and give the best performance.

The vast majority of the parts used by ourselves to rebuild these machines are manufactured by ourselves in our own workshops to the same exacting standards set by the original manufacturers.

We are highly specialised in this industry and have earned an international reputation for the quality and reliability of our work.

Our skilled engineers have many years experience in adapting and rebuilding these machines and understand every aspect of their operation.

We pride ourselves on our rapid response time in the event of breakdowns.

*2021 sees the launch of our new 7 inch touch screen systems mounted central for ease of operation 

Summary of work for Full Rebuilds

We inspect all machines prior to purchase or if sourcing from overseas, the machines are checked via a competent body on our behalf.  We will only purchase machines that are free from extensive damage. 

Connect electrical supply and test, list faults and any abnormal noises i.e. worn bearings, bruised gears in main drive. 

Remove all chrome and anodised parts; send to plating company to be re-nickel plated or anodised. 

Remove all wiring and dispose of. 

Whilst dismantling check all parts for wear or breakage, add to list for purchase or manufacture prior to rebuild. 

During the dismantle operation all oil pipes are removed, distribution links are dismantled, cleaned and seals are replaced. 

Removing of clamshell to leave empty base.  All parts removed are completely dismantled, cleaned and checked and all broken/worn parts are replaced. 

Gripper arms are refurbished: replace springs, rubber inserts and bushes. 

The clamshell has 3mm removed from face creating a removable bed plate. 

All toggle bushes are replaced if necessary at this point. 

Main motor: Main motor replaced, including starter and isolator. 

Cleaning:  Larger parts to be steam-cleaned, all exposed metal to be sprayed with oil to prevent rusting. Smaller parts including nuts, bolts and springs are put in the parts washer. 

Separate the parts to be chemically blacked or painted. 

Chemical blacking: To prevent exposed metal parts from oxidisation. The parts are given a five-stage solution process. 

Spraying: Prepare parts, mask up exposed metal surfaces not to be painted. Paint with two-pack air drying on larger items, smaller items powder coat and oven bake.

NB: This is a general overview of our rebuild process, some features vary by machine type

We offer full Hot Foil Conversion Systems for all Heidelberg Presses.

The basic system incorporates a single roller which is stepper motor driven giving total accuracy of foil pull. The distance can be set up to 320mm in increments of 1/10th of a mm. Foil usage is 400ft. on a 1" core (122 metres x 25mm core) 

Please contact us for detailed specifications.

Heat Plate: constructed from aluminium, which has 6mm drilled and tapped holes for die mounting. The plate is precision surface ground for accuracy.
The final results are a lightweight durable heat efficient plate.
Control Panel: Special built enclosure mounted to the machine, which can be turned to a position to suit the operator. The controls are accessed via a bespoke keypad and viewed by liquid crystal display. The functions are foil metering, foil alarm, step and repeat (up to 99 steps), and impression counter.
The controls are accessed by 3” touch screen, we now offer Honeycomb plates for 13/18 platens
Touch Screen: This option is available across the whole range of conversions.
Can be used in conjunction with a networked computer to access information for management evaluation reports. Our system can also be linked via modem for fault analysis.
In many cases the touch screen can be positioned to suit the preference of the operator.
