The Krownmatic is a furnace for aluminium holding without crucible, heated by means of electrical resistances of silicon carbide that includes an electronic dosing system. The furnace housing is thermally insulated and it is manufactured in carbon steel. The furnace lining is made of refractory concrete resistant to aluminium; this concrete has great toughness and hardness. Due to the refractories high quality and with proper maintenance being carried out, the furnace can reach a more than 10 year useful life.
The Krown dosing furnace has been developed to obtain high quality castings with minimum consumption, notwithstanding all the required safety measures to be taken into account.
Krownmatic Furnace Advantages
Energy efficiency. Electric consumption is 1/3 less compared to traditional holding furnaces.
Accuracy in the dosing +/- 1%.Guaranteed a less than 0,05% loss in aluminium due to oxidation.
Success in the mechanising thanks to the reduction of hard spots.
Increase in the castings mechanical properties in an 80%, as the aluminium oxide input is minimised.
Accuracy in temperature +/-1 C.
Real loading possibility while in production.
Minimum consumption of compressed air thanks to no de-pressurisation (averages > 10m3/h).

works with its highly trained specialist staff to provide the most appropriate technology to the customers’ production by supplying the high quality equipment and machinery. A new vision is added, as needed by the sector, such as system installation, machine retrofits and automation systems. Velacast is the sole agent in Turkey and perpherals of high quality brands such as LK Machinery (Die casting machines), Idra (Die casting machines), Krown (furnace), Meccanica Pierre (trim presses), Unicomp (X-Ray machines), Alrotec (casting chambers and plungers).
LK Machinery is the largest manufacturer of hot and cold chamber injection machines in the World. In 2007, General Motors riveted its power with the order of 17,000 tons of injection machines purchased for Bedford-USA Powertrain Plant. LK Machinery continued to make its mark on the global market by acquiring 70% of the Italian IDRA company in 2008. For the present, LK Machinery is 100% owner of the Idra company.
We, as VELACAST company, have been continuing our works to meet all needs of our customers using Aluminium and Zamak Injection by adding our cooperation with LK Machinery to our IDRA agency which we have been continuing for 10 years. Besides, we perform successful installations and start-ups of die casting cells all around the World, thanks to our skilled technical staff. Furthermore we can perform your any kind of machinery installations and start-ups in Turkey and near abroad as per our mutual consensus.
