Multisensor sees More Preform Bottles Produced
Mold and Hotrunner Technology have for many years, been using a Mahr Multisensor OMS400 measuring machine, to ensure quality of their products.
Simply rotate and continue to measure.
All 3 sensors are linked to a single calibrated reference and can be used in any combination to measure the part.
For example, you can use the laser and touch trigger probe to align the part and the camera to measure small or complex features which cannot be accessed with the probe.

The 3D CMM has a measuring range of 250mm in X, 200mm in Y and 200mm in Z and is build on a solid granite base.
All axes are equipped with precise roller bearings and the stage is made of composite aluminium featuring low mass a high rigidity.
The optical system uses a 5.8 to 1 variable motor zoom together with a high resolution CCD camera and grey level evaluation.
Other magnifications as well as an optional 2 step zoom are available on request.
Illumination is software controlled using fibre optic light sources for coaxial and backlight and a 4 segment programmable LED ring light.
The touch probe is standard Renishaw and uses a wide range of styli including star probes.
Also available is the integrated automatic probe changer.
A "Through The Lens" laser is a coaxial focus laser integrated in the Multisensor head.
It uses computer controlled intensity parameters to suit an assortment of different materials and colours.
The laser allows for rapid surface focus with an average focus time of 0.2 seconds per point.
Dynamic laser scanning of 3D topographical profiles at a rate of 500 points per second is also available.
The length measuring uncertainty according to VDI/VDE 2617, alternatively ISO 10360-2, is as follows; E1= 2.2+L/150, E2= 3.2+L/125 and E3= 3.9+L/100.
Note: As E3 is a 3D volumetric uncertainty it can only be established with a touch trigger probe.
Therefore, the E3 value is only available with the touch trigger probe option.
A higher accuracy version is available which uses higher resolution scales for more precise positioning and laser focusing.
