Technical description Laboratory press Type WLP S
Benefits
Repeated consistency of pressing force adjustment
Homogeneous temperature distribution
Good heating up ratio
Rapid cooling
Modular concept based on module system
Use of high-quality standard components
Reliable machine construction made in Germany
Description
1.) Mechanic
Press engineered as an up-stroke column type with easy access
Clamping system fully hydraulic, with quick-fill action with rapid closing and
opening cylinders
Main piston made of solid gravity die cast
Sealing of the main ram with wear-resistant lip seals, use of guiding strips
and dirt scrapers
Leakage oil feedback for the main cylinder, no cleaning necessary
Pressure plates made of solid rolled steel, deflection resistant, for constant
pressure distribution
Heating plates in quality steel, machined out of solid blocks, wear-resistant
Heat insulating plates high-pressure resistant, without asbestos, grounded
both sides

2.) Electric
PLC-control, manufacturer: Siemens, type
S7
Control cabinet right side of press
Control buttons, control lights and
emergency-off
Selector switch for hand- and automatic
operation and setting
Operating Panel MP 277, 10“, colour
Internal memory store for machine
programs
„Press-easy“, the intuitive press software
Temperature control executed as software
controller in the CPU of the SPS-control,
set point adjuster and actual value indication in plaintext, free choice of
tolerance range up and down for each temperature value
3.) Hydraulic
Hydraulic drive
Hydraulic drive by silently running axial piston pump
Proportional control with integrated closed loop pressure control
Proportional flow control
Subsystem including a preload and
unload manifold to provide a rising or
falling force characteristic
All functions of the press are controlled
right out of the pump and ensures
highest reproducibility

Hydraulic control
Hydraulic control of compact design
Press safety system according to EN 289 designed as a high integrated
manifold
Designed for easy maintenance
Leakage-free connection system for all piping and connections
Noise optimised pump for den Laboratory use
Filter
High pressure
Return
Intake air
each 10 µm
4.) Safety
1 pneumatically driven protective cover, in the front
integrated in a swivelling safety device in the front, which can be swivelled
easily for maintenance and cleaning.
Pressing area observable through safety glass
Protective fence outright with accessibility for maintenance
