Casting

Iron and Steel Castings

Combined with over a century of experience in machine tool manufacture and superior technology, John Heine has become synonymous with high precision iron castings, steel castings, metal casting and white iron castings specialising in wear resistant alloys for the quarrying, mining and power generation industries.
The foundry uses Solid Works for managing CAD drawing files and AFS Solidcast for modelling the solidification of castings prior to manufacture in order to ensure sound castings. A glow discharge spectrometer is used to monitor the melt to ensure compliance with specifications. Ceramic runners and filters are used to ensure cleanliness of the metal in the mould. The induction furnaces are designed to tilt backwards for slag removal, prior to forward tilting for tapping out over a clean lip. Castings are heat treated in one of the PLC controlled gas ovens with multiple thermocouples connected to a print recorder for monitoring temperatures of individual castings inside the furnace. Machining of the castings is done in-house, where CNC programs are generated on a Cam Works CAM package.
