Present for over 30 years in the sectors of waste recovery and energy production, Cronite is one of the major players specializing in the production of wear parts used in these processes.
We are at Bois-Energie in Nantes in partnership with TISKA France et DAMRYS. 29-30 January 2020
Visit us on Stand Hall2 – Z24 !!
The Salon Bois Energie for Industry and Municipalities is the reference event for the industry and municipality wood energy sector in France and represents the largest gathering of stakeholders, with typically more than 125 exhibitors and represented companies from across 10 European countries present and 3000 professional visitors.
The Exhibition is an annual event with a broad programme over two days encompassing a rich international conference with simultaneous translation, international business meetings, study tours, the innovation competition and two parallel complementary events for biomass/waste to energy.
Cronite conducts environmental studies to better measure the ecological impacts of its foundry processes.
The study below gives a surprising answer: for the same net kilogram of refractory alloy cast at Cronite foundries, the Green-Sand process is 25 times better for the emissions. This result was computed by our R&D Center in Brno in October 2019.
All our customers know the main differences of those 2 processes when their fixturing solutions are made from one or the other ways. Basically Lost-Wax allows thinner and complicated shapes when Green-Sand is preferred for its better ductility, lifespan and stress resistance. Lost-wax has advantages against Green-Sand also for the precision and the surface quality.
Cronite’s Design Office knows what process to use for which product and advise its customers accordingly. At the drawing stage, Cronite’s designers decide which way to be used. Up to now, the environmental factors were not considered, as no study was available to decide.
This study will now be improved in the near future by comparing the same both processes on water consumption
1GREEN-SAND : The part are made by pouring liquid metal into a printed shape in a mix of normal sand, clay and water. No chemical is involved except the resin parttern which is made once for the all batch, and stored for the aftermarket. No major energy is required except obviously the one for melting the material.
2LOST-WAX : The part are made by pouring material into an empty hot shell. The shell is made of refractory material dried around an injected wax part. Energy is needed not only for melting bu also for drying the shell, dewaxing the shell (melting and pouring out the wax) and pre-heat the shell. The wax losses generate also son carbon emissions.
