New presses from KUNI
Production press (SRDS 250/250)
Production press 250 tons
The press is built up as a 2-parted construction that is bolted together.
The upper part consists of cylinder and pressure shoe.
A filling drawer comes in from the back and puts material in a chamber into the lower part that has an integrated pressure shoe and via hydraulic cylinders mounted in the sides the material is compressed to an insulation product.
The construction is thus extremely maintenance-friendly and with the least possible total height.
High pressure press 6000 tons
A welded ring-frame construction, where the pressure cylinder and the platens are mounted in the middle.
The platens are doubly channel drilled and make use of the counter current system, providing a very accurate heating.
This system also has the possibility for cooling in order to make the product stable.
The press has 15 pcs. Ø380 mm cylinders and it weighs approx. 90 tons.
The photo shows a machine line with 8 hydraulic presses.
Emptying of the forms takes place from the back by means of a robot solution and in front the work piece package that consists of a number of glued wooden veneer plates is mounted manually.
The product turns out a moulded designer chair.
The press is used for compaction of a combination of pre-glued products into a sandwich.
This type only has a rather limited pressure and slight heating of the platens, but the platen area is very large, 3.6 x 12 meters.
A 2-parted through-feed belt is integrated in the press for in-/outlet conveyance of the product under continuous operation.
Production press 1110 tons
Moulding press 1100 tons
Heavy welded steel frame construction, The press is used for embossing wooden product.
The platens are connected to a heating system that can control the temperature individually on each platen very accurately.
Pass-through press with Vision System
Vision system is for scanning of work pieces when fed to hydraulic platen press.
The system is provided with optical cameras that electronically scan the width of the work pieces for encoder comparison with the length measure.
These data are transmitted into a PLC control that via the screen marks the positioning of the work pieces in the press. Subsequently the hydraulics can precisely regulate the pressure through proportional valves on each cylinder and thus the work pieces are under equal pressure, regardless their position – also in case there are only work pieces in one side of the platens or in case there is only a single work piece at the press outlet.
Vision System eliminates the risk for work pieces not being correctly positioned or the lack of adapter work pieces, which are used for filling/balancing the press surface area.
This secures against other press construction parts being overloaded, which might otherwise result in damaged/bent platens.
The development of the vision system has been implemented with grants from the EU and from the rural district program by the Ministry of Food (FVM.dk).
1500 tons cold moulding press
The press has the function to secure a round steel material, which is cold moulded in the end of a stucco cylinder.
The outer dimensions of the machine
are 2100 x 2400 mm
and the weight is 12.5 tons.
This press is a welded steel construction with an integrated index table.
The functioning takes place by means of a backstop fixating a work piece that is expanded using a pressure mandrel and the index table turns a new work piece into position.
A robot solution dismounts and mounts new work pieces continuously.
