Investment casting

At Ecrimesa Group, we have more than 50 years of experience in the world of investment casting.

What it is

Investment casting is a highly versatile process, permitting great liberty in the design of the pieces, including complex pieces, and a big variety of alloys. It is especially suitable when greater flexibility in the size of the loads as well as a homogeneous and elevated superficial quality.

With a daily production capacity of more than 8 tons, we provide fully finished pieces, including machining and heat treatment.

Experience

Ecrimesa Group have developed more than 7,000 projects, providing us with ample experience in the production of stainless steels, carbon steels and aluminium parts. Investment casting allows for greater design liberty, with complex pieces including complex internal shapes.

The elevated superficial quality of the products allows to leave out some of the final machining operations, lowering the final cost of the pieces.

This technology offers a higher level of flexibility with the possibility of producing small numbers of pieces up to bigger loads, as well as repeatability through the different loads, safeguarding homogeneous quality.

Design office and fabrication of molds:

In our own office for design and fabrication of molds, we offer our clients a complete assessment to adapt their design to the process of investment casting. Our designers’ work experience is enhanced by simulation software (Magma Soft and Inspire Cast).

With our printing devices for wax printing with no prior fabrication of a mold, we can produce rapid prototypes. This is very helpful for the initial steps of the production process when the customer’s design is not yet final and various prototypes are necessary before producing the final mold.

This solution eliminates the barrier of constructing a mold in the early phase of the production or for projects with low production numbers, which are hampered by the investment in the mold.

Installations:
Wax injection / Ceramic Shell room

The wax workshop offers a variety of possibilities, combining automatic, semi-automatic and manual wax injection machines. This allows to satisfy all demands of the clients.

We also have an automatic installation to extract soluble wax taps. We can apply the technology of prefabricated wax taps when necessary.

The production process of the shells has been automated, with two robotic production lines. These lines operate under controlled conditions in terms of temperature and humidity, managed by modern air conditioning systems.

Our installations allow for us to offer a high level of rentability and flexibility.

Metallurgic laboratory – metrology

We operate a complete metallurgic laboratory with more than 8 technicians that do not only manage the continuous controls of the melting process and heat treatments, but also make X-Ray controls and digital tomography, fraction controls (hot and cold), digital analyses of pictures and microstructures, corrosion controls, and NDT.

Heat treatment

Internally, we operate a heat treatment plant with 4 furnaces for annealing and normalizing with carbon control, 3 automatic lines for hardening and tempering and one line for aluminium T6 treatments, all of them CQi-9 certified. With us, the customers receive everything from the same provider, from the design process and planning until the finished pieces, always with high quality guarantee.

Machining services

In 2005, we incorporated machining services into our group in order to offer fully finished pieces. Internalizing these machining operations allows for a higher versatility in the design phase, as well as in the finished loads.
