Measuring laboratory

Lumel Alucast is a certificated supplier in the scope of ISO 9001:2015 and standard IATF 16949: 2016. We also take care to ensure
the compliance of our castings with requirements concerning their properties and impact to environment, what is confirmed by certificate of compliance with the requirements of ISO 14001:2015.
At Lumel Alucast main goal is customer’s satisfaction, so our top priority is ensuring the quality for pressure castings.
We strive to continuous improvement of our processes according with the assumption of the Quality Management System.
The result of a pro-quality approach is assurance, that customer requirements are met at every stage of production, from input material checking to finished products. At our plant we aspire to create the quality, not only control the quality of our castings – that is why continuous improvement process is very important aspect for us.
As Edward Deming used to say: “Quality is a way of thinking that makes us use and constantly look for the best solutions”

3D geometrical
measurements

The relatively young but dynamically developing field of measuring geometric quantities has also found application in our laboratory. Using coordinate measuring machines we perform unit measurements as well as for serial production. Thanks to integration with CAD / CAM systems, we are also able
to perform computer analysis for irregular surfaces.
To measure the functional geometry of the workpieces we use the fast, simple and economical MarSurf XC-20 contour measuring system that meets the high accuracy requirements. For this purpose, we use, among others Wenzel system with MPEE = 2.6μm + (L / 450mm) μm – in the measuring range 800/1000/700 (X / Y / Z). We are able to perform more precise measurements of shape, runout and direction deviations using the MarForm MMQ-400 device,
in the range of 280 / 900mm (X / Z), with a maximum allowable measurement error of 0.04μm.

Supervision over control
and measurement equipment

One of the main tasks of our laboratory is to supervise the control
and measurement equipment. In this regard, we supervise ring gauges, piston gauges, thread gauges, two-point and three-point bore gauges, calipers, micrometers, dial gauges and digital, altimeters and depth gauges.
For this purpose, we use, among others, vertical and horizontal ABBE length gauges. We also have a set of gauge blocks in the highest accuracy class.

Hardness
measurements

To test such an important feature as the hardness of the material we use
the system of the leader in the production of this type of equipment by Struers. The tests are carried out using the Rockwell HRC / HRB method
in the complete load range of 9.8N to 2450N.
With this system, it is possible to measure the hardness of plastics, carbon materials and to measure indirect HVD / HBD methods.

Thickness
measurement
of galvanic coatings

We perform coating thickness measurements during the NDT test.
For this purpose we use LEPTOSKOP® 2041 from KARL DEUTSCH.
We carry out tests on Fe / NFe substrates (0 – 500 µm) with a measurement uncertainty of 1% ± 1 µm for coatings <100 µm and 1..3% ± 1 µm
for coatings> 100 µm.

Alloy density
index analysis

The density index is a parameter that determines the purity of the molten metal.
For pressure die-casting of aluminum alloys, the permissible value
of the density index is 0-3%. In order to test the alloy density index
after the melting and degassing processes, we use the Aluminum Density Tester Martech-VCTM 0017, which allows us to make samples and calculate the obtained results using the NAGATA FATH 06S scale.
