Main mechanical components of our Rotational machines:

  • Oven having a unique shape to reduce the air volume around the moulds to minimum and to achieve high efficiency with low energy consumption. Oven structure in robust steel profiles with high thermal insulation attained through interposition of high density oriented fiber rock wool with a thermal conductivity of 0,043 W/(mK). Besides are applied fibre glass fabric gaskets to minimize heat loss (eco-sustainability).
  • Adjustable air diffuser.
  • Doors opening and closing automatically, independent one from the other and with handling at variable speed.
  • Electropneumatic operating gate for automatic opening and closing of the cleft for arms passage, which is fit to avoid the loss of heat in the working area and to optimize the oven performance.
  • Variable speed electric fan for the residual fumes extraction.
  • Safety control device against the accidental stop of the fumes extraction and/or oven fan.
  • Digital burner management of a leading worldwide brand, using the most modern microprocessor technique for calibration, command and supervision of all its functions. The digital burner, as it occurs with the electronic injection systems of cars, allows high performance with reduced consumption and maintenance. In addition, a special mixing device with internal gas recycle reduces gas emissions in the atmosphere.
  • Safety control device against over-heating of the combustion chamber.
  • Station used for moulds pre-cooling, pre-arranged for electric trolley fan.
  • Air/water forced cooling chamber with tubular steel structure, bottom in stainless steel, walls and ceiling in steel protected by epoxy paint. Several types of high-efficiency electric fans with water nozzles are foreseen to grant reduced cooling times without thermal shock for the moulded item. Complete with electro-fan for steam extraction. Possibility of doors opening and closing automatically.
  • Carriages (from 1 up to 4) in robust steel profiles planned to grant the greatest strength and make the arm changing operations easier and quicker. Handling by self-braking gear-motors, of worldwide leading brand and driven by inverters.
  • Mould-supporting arm transmission by self-braking gear-motors of worldwide leading brand and controlled by inverters, which allows speed programming with extreme precision and in an independent way on the two axes (possibility of encoders for axes automatic positioning).
  • Mould-supporting arm with high loading capacity complete with case-hardened and hardened drive gear. Predisposition for the application of moulds internal temperature control. Thermal treatment to avoid any deformation at high temperatures and equipped with two independent lines of compressed air (high and low pressure with the possibility of using azote).
  • Mould supporting arm head hermetically sealed. Bearings and bevel gear pair with case hardened and hardened gears not in contact with the oven environmental thus avoiding oxidation and dirt on the moving parts.
  • Carriages electropneumatic lock in the correct working stations and stop control in double security position.
  • Pulpit console for the management of the manual operations of moulds loading/unloading, carriages advance shift, door drives and double emergency circuit. Photoelectric cells protection system and metal gates for the dangerous zones (CE rules).
  • Vertical opening control panel IP55 with ergonomic industrial touch-screen PC 15”.
