The lab press series PW is recommended for frequently changing pressing tasks in small to medium quantities, which can still be handled manually and when using different types of pressing tools. These models are very easy to use, extremely robust and can be placed on lab benches, workbenches or press trolleys.
The manual 2-column laboratory presses of the PW series could be described as the classics of lab press technology, which have been optimised over decades.
The press tool or material is centered on the lower pressure plate and the upper pressure plate is rotated down with the adjusting spindle until it rests against the pressing material. The hydraulic pressure generated by operation of the manual pump causes the piston in the hydraulic cylinder to extend upwards. The pressure load and thus the system ram force is displayed directly on the manometer in kN and is unable exceed the permissible maximum value thanks to the adjustable pressure relief valve.
Other outstanding features include the hydraulic cylinder with integrated oil tank, the hard chrome-plated press columns, the plasma-hardened adjusting spindle with trapezoidal thread and the double-acting manual pump, which generates hydraulic pressure during both the downward and the upward movement of the pump lever.
The PW series can be individually adapted to many user requirements and equipped with many add-on components.
All the PW series lab presses are also available with heating/cooling plate systems up to 300 °C or 500 °C. Furthermore, the lab presses can also be equipped for installation in glove boxes and can be retrofitted for combined manual and automatic operation with an electrohydraulic supply.
General
The PW series manual 2-column lab presses are the classics of lab press technology. The lab presses, which have been optimised over decades, are characterised by their easy handling and extremely robust design.
The 2-column construction is very compact and space-saving. The press frame consists of a base plate, two hard chrome-plated columns and the press yoke. An adjusting spindle with trapezoidal thread is attached to the press yoke which serves to apply the upper pressure plate quickly to the pressing material or pressing tool. Thus, direct pressure must only be applied via the hydraulic manual pump.
Centered on the base plate is the hydraulic cylinder with adjustable pressure-limiting valve and integrated oil reservoir. The pressure is built up by the hydraulic hand pump on the right side of the base plate. The manual pump can also be mounted outside the box for installation in the glove box, regardless of the press frame.
The PW series can be individually adapted to many user requirements and equipped with many add-on components.

General
The PW-BOX series lab presses are specially designed for use in glove boxes. The 2-column press frame and the hydraulic cylinder are based on the basic version of the PW series. However, the complete hydraulic manual pump with pressure-limiting valve, pressure gauge and oil reservoir is mounted outside the glove box. The connection from the manual pump to the hydraulic cylinder is acheived with high-pressure hydraulic hoses, the passage through the wall of the glove box is very easy thanks to bulkhead fittings.
For better handling of the adjusting spindle in the glove box, it is usually recommended to use the selector fork. By turning the selector fork with the adjusting spindle, only the upper pressure plate is applied to the press tool or press material. Pressure generation is very simply thanks to the external hydraulic manual pump. Should an oil change be necessary, this can be done directly on the oil reservoir of the external manual pump. Assembly work in the glove box is not necessary.
The PW-BOX series can be individually adapted to many user requirements and equipped with many add-on components. It is also possible to integrate heating/cooling plate systems, please contact us for your individual requirements!

General
The PW-KIP series lab presses are equipped for use with hydraulic high-pressure tools for cold isostatic pressing (KIP). In cold-isostatic pressing, the material to be pressed is packed in a flexible silicone mold, sealed liquid-tight and then compressed at high pressure in all spatial directions simultaneously in the hydraulic fluid filled press tool.
The PW-KIP is equipped with a special workbench, on which the hydraulic high-pressure tool can be pulled very easily to the front for loading and unloading. For this purpose, the base of the tool is pressurised with compressed air, which allows easy sliding of the tool. The lab presses are equipped as standard with a safety guard and a pneumatic maintenance unit with pressure regulator, special high-pressure seals and special high-pressure liquid are included.
For standard uniaxial presses, the high-pressure tool and the die ram are simply removed, and the lab press can then be used flexibly with various press tools for standard press applications.
The PW-KIP series can be individually adapted to many user requirements and equipped with many add-on components.
