Points and forms Leica Absolute Tracker AT 401 at the Service of Mould Production

Corima - France

Corima Technologies capitalises on significant knowledge on casting equipment and the production of associated complex components. The company has specialised in electroforming, that is, a nickel or copper electrodeposit to obtain a form. This electrodeposit therefore consists of forming a very thick metallic deposit on a model with the aim of obtaining a mould or a technical component.

For more than thirty years, Corima Technologies Management has undertaken to verify compliance with their clients’ requirements and acquire suitable means to implement an effective quality system. The continuous improvement in products and services, in addition to their quality at each stage of their construction, is part of the research and innovation values implemented by the company.

It was from this standpoint that Corima Technologies enlarged and modernised its production during 2009 in order to strengthen its position as an electroformed mould global specialist and work with its clients on large dimension projects. In parallel, the company based in Loriol-sur-Drôme is targeting new markets by developing the production of standard parts for the aeronautical, medical and general industries.

During the quality control process, Corima Technologies uses climatised premises equipped in particular with a large dimension manual coordinate measuring machine (3000 × 1500 × 1500). However, for production of moulds up to 7 metres, the CMM was no longer sufficient. The company then sought a new solution which, because of obvious constraints associated with handling large pieces, had to be portable in order to move to the component and not the other way round.

The solution of a measuring arm was initially envisaged. However, operation restrictions for such a large volume along with the significant precision required prompted the regional ROMER portable measuring arm manager to advise using a laser tracker instead. The acquisition of a laser tracker therefore represented the best possible solution and offered portability, precision and flexibility.

“We had to reflect for approximately two years before moving ahead with the adventure of a laser tracker. Market analysis, decrypting of proposals and analysis of service provisions all take time,” explained the Production manager and co-founder, Mr Christian Pascaud. He went on to say: “the Hexagon Metrology group easily proposed the best performing and most adapted products whilst at the same time offering a very professional consultancy, along with local, regional, national and international support. We were very impressed with the Leica T-Probe solution but it did not fit our budget allowance”.

The launch of the Leica Absolute Tracker AT401 met the expectations of Corima Technologies. “We were immediately impressed with its performance and portability. We have full confidence in our new partner. Our team has welcomed the new tool with real enthusiasm from the outset, and the application training provided by Hexagon Metrology has reinforced our decision,” points out Mr Pascaud. Very simple set-up and extremely quick measurements offered by the Leica AT401 quickly pay off: a real time saving of 50% on measurements! “The laser tracker leads us not only to save time but has opened up new opportunities for services that Corima Technologies can, as of now, propose.
Indeed, we always guarantee the implementation of tools for our clients. The Leica AT401 therefore ensures completion of this task in a quick, flexible and very professional way, which also offers a capacity for follow up over time. When we are familiar with the life cycles of a product within the aeronautical industry (20 years!), it is better to use equipment at the cutting edge of progress,” explains Mr Pascaud.

Today, the Leica Geosystems laser tracker is used at Corima Technologies for several measurements: inspection of tools and forms, real time setting, monitoring the manufacture of master tools in addition to monitoring the manufacture of intermediary elements prior to electroplating bath or for installation with the client. “We take measurements everywhere, we can no longer do without it!”, concludes Mr Pascaud.
