TVCs are fully automatic, robust, easy to use pressure over vacuum casting machines designed for small and medium casting laboratories. This family of machines work with the well known pressure over vacuum concept, thus preferring the perforated flask against the solid ones. Melting is achieved in protective atmosphere (Nitrogen, Argon or Helium) while a strong vacuum pump is provided in order to boost the suction effect into the mould. As soon as the metal has entered the mould a strong compression takes place on top of the tree to reduce shrinkage porosity. Flask size can reach up to 300mm in height and 160mm in diameter. Crucible graphite consumption is greatly reduced thanks to the gaswash procedure which removes the oxygen in few seconds from the charge loading operation. The machine is fully automatic making the operator’s job very easy (you simply have to load the alloy and flask and then press the START button). This will give you the most consistent result flask to flask. And remember, meanwhile the machine is running the cycle, you can do other important jobs in your factory. Having a consistent, robust and easy to use machine in your factory is the key factor for a reliable casting production. Gas Wash Procedure Crucible loading operation introduces oxygen The Gas Wash Purge procedure removes the oxygen (1) in a very fast and efficient way and then refills back the chambers with Argon or Helium gas (2) Compared with the traditional crucible protection with flow-meter regulation the consumption of gas is dramatically reduced and the alloys oxidation is minimized Moreover the crucible life is increased: TVC series crucible last up to 250 – 400 casting cycles according to the graphite quality Melting Advanced Self Tuning thermoregulation (AST TM ) with exact temperature control of the melted alloys Medium frequency induction heating stirs the melted alloy and leads to a perfect homogeneity Pulse Stirring Management (PSM TM ) for an extremely low frequency stirring Injection and Compression When the stopper opens, as soon as the molten metal fills the flask, a trigger is launched to the over pressure valve which will make the gas flow enter smoothly and quickly to compress the tree during the solidification phase to reduce shrinkage porosity. Tree protection after casting After the solidification phase, the flask cools down in a protective atmosphere to avoid oxidation. A blinking lamp will signal the operator that the cycle has ended and the flask can be removed

Unquestionably the ideal laser for cutting and marking, thanks to the use of ytterbium-doped fiber optics with low environmental impact and low maintenance (up to 50, 000 hours of operation). It can be used to mark objects of any metal, engrave photographs, logos, trademarks and texts with a maximum size of the marking area of 180x180 mm and with resolutions as high as 20 μm. The machine is small, with readily accessible working chamber thanks to the hatch that opens on 3 sides. The FiberLUX family of lasers now offers a power range from 20 W to 100 W, to cover all your production needs. Equipped with a motor-driven Z-axis with movement resolution of 0.01 mm, and an innovative, user-friendly focus system with overlapping pointers, it can also be equipped with an internal videocam inside the laser chamber, for optimization of processing and possible remote assistance. FiberLUX is supplied complete with software capable of importing files from the most well-known computer-design programs currently in existence (svg, dxf, bmp, plt, jpg, dwg, etc.), and is also equipped with specific cutting software Made by ElettroLaser. Every machine can be equipped with a range of options such as: high precision rotating axis system, electro-pneumatic plate driver, exhaust fan, clamp for blocking pieces, movable in the X and Y axes, and a system of pneumatic hatch opening. Main features Pulsed laser source in fiber D.S.P. Technology Red double pointer for positioning Z-axis with 'stepper motor' controlled by software USB interface for connection Cooling via forced air Small size Ready for the 'Trademark’ High frequency scanner head, 1 Mhz Software for cutting 'Made by ElettroLaser' 24 month warranty Applications Engravings on rings, bracelets, medallions, flat and slightly curved surfaces with up to 4 cm unevenness Excavation by layers and 3D bas-reliefs Engraving of photographs, names, designs and logos, including trademarks Engravings on watch faces and eyewear of any metal material Manual cutting of the individual piece, or automation for mass production
