General overhaul

The scope of a general overhaul includes:

  • Face milling of the clamping plates or on request (optional) welding with CrNiMo electrode to avoid crevice corrosion between the mold and the clamping plate. The welded-on layer is rustproof and resistant to corrosion.
  • Reworking of the recesses for the casting chamber holder and the T-slots
  • Renewal of all column guide bushings and scrapers
  • Post-rotation of all joint bushing holes and renewal with new joint bushe
  • Renewal of all bearing bolts
  • Renewal of the 4 machine pillars
  • Renewal of the 2 pieces of crosshead guide columns
  • Overhaul of the central lubrication by renewal of all dosing elements
  • Overhaul of the closing and ejector cylinders and re-sealing
  • Check and repair all hydraulic components
  • Assembly of the closing part with functional test
  • Revision and reorientation of the machine bed
  • Overhaul of the complete press-fit part (weft and multiplier cylinder with piston rods, etc.)
  • Overhaul of the drive unit including pumps, with sealing of the hydraulic blocks
  • Renewal of the complete machine wiring and installation of a new SIEMENS OP 7 control with control column and cabinet as well as programming of the control analogous to the existing software
  • Painting the machine according to customer requirements

Optional work:

  • Welding the clamping plates with CrNiMo electrode
  • onversion of the hinge pins from a fixed to a floating storage
  • New joint cover (both sides)
  • Protective doors (operator and back of the die casting machine)
  • with electric drive and linear guides, uncoupled from the machine on the floor or mounted on the machine bed, without upper and lower guide rail, thus free access to the mold installation.
