Pioneer in Spain in the production of elements for molds and dies
We have come a long way since those early days. Since then, it has always been our aim to supply precision products of the highest quality.
Our productive capacity has been reaffirmed and increased thanks to the establishment of an own production plant in 1996.
Additionally, the acquisition of small machinery for our Badalona plant allows us to produce some special parts in 24h.

The inquiries about standard pieces can be directly managed through oure-shop. For special parts, you will receive an answer the day after your inquiry.
The surface hardness must be measured with a micro hardness tester. In Eldracher those equipments are the FM-800 model of the Future-Tech Corp. brand and they are calibrated annually.
There is a frequent mistake that must be avoided, which is trying to measure the surface hardness with a penetration hardness tester, since the hardness we would be measuring would be the one in the core and not the one in the surface.
The method used in Eldracher is trough X ray. In Eldracher we use the Thermo Scientific Niton XL3t X ray machine, which allows us to obtain the exact chemical composition of all the steels and of the pieces produced with them, being also able to issue the corresponding certificates.
Measuring the inner hardness in a curved surface it is not as simple as it may seems. It has to be measured with a penetration hardness tester but under certain conditions.
When the surface is curved, we have to apply to the obtained measure a correction of the hardness obtained in curved surfaces according to the attached table.
When the penetration hardness tester is used in curved surfaces the tip of the penetrator has a less effective contact which produces a hardness measure lower than the one that the piece really has.
Therefore, to the obtained results with the hardness tester we have to add the value of the attached table depending on the diameter and the result.
Additionally, it is very important to verify that the puncture has been made totally perpendicular to the curved surface.
Evidently, with the use, all the hardness tester lose its calibration, that is the main reason why they have to be recalibrated annually.
