The laboratory press Polystat 300 S

The laboratory press Polystat 300 S has platen sizes of 350 x 350 mm and a working area of 300 x 300 mm to produce a variety of flat samples and the use of moulds in the laboratory.

Hydraulic

The machine is laid out as a four-column-press with an integrated high pressure hydraulic system to allow high press forces with a double-side operation cylinder. The hydraulic system is running under oil and allows a press force of 450 kN (working pressure 500 N/cm²). The hydraulic pressure can be adjusted between 40 and 400 bars and reaches in combination with an electronic pressure control unit an accuracy of +/- 5%. Leakages are compensated automatically.

 

A continuous closed loop control for pressure accuracy of 1%, higher press forces, additional hand pump and other hydraulic modifications can be done according customer requirements.

 

Press plates

Press plates consist of several layers. The working area consists of a flat ground steel plate; press plate can be also delivered in a hardened version. On request the basic daylight opening of 195 mm can be increased up to 300mm for the use of larger moulds.

 

Heating/cooling

A combined heating-cooling-plate with a integrated cooling bore system and long-life heating cartridges made of aluminium provides an equal heating distribution and a quick cooling under pressure. Electrical power of 8 kW in each plate insures a temperature gradient of 10°/min and a maximum temperature of 300°C. Heating is controlled by µp-controller and solid-state-relays for a precise temperature distribution of +/- 4°C (optionally +/- 2°) on the working area.

For cooling under pressure water is flowing thru a counter current bore system. Depending on temperature range gradients between 10°C/min und 20°C/min can be achieved.

 

Polycontrol

The optional Polycontrol is a combination of touch screen and PLC-control for comfortable operation of the machine. The functions can be operated from different screens. An intensive use of graphic elements provides easy operation. Polycontrol includes set point management, program management with time sequences in four steps and several helpful functions for the daily use in a laboratory. On request an interface to Microsoft Excel is available

 

electric

The control panel is mounted directly to the press unit. All electrical parts and hydraulic units are mounted in the frame of the machine and allow easy access for maintenance purpose.

 

safety

For the safety of the operator closing of the press is done with a two hand operation. If necessary the machine can be delivered with a safety cage and a light beam.

 

two-stage version

The machines can also be delivered in a two stage version with a second stage (lower stage for water cooling only). Optionally the lower stage can be equipped with heating plates.

 

Machines are delivered complete with all integrated controls and hydraulic.

 

Other modifications can be done according customer requirements.
