Programme overview
Introduction:
Foundry and metal casting operations, covering sand, investment and die casting, melting and casting defects, is a 5-day course for foundry managers, casting process engineers and melt-shop, moulding and quality supervisors, ending with a Casting Quality and Scrap Reduction Plan for a case foundry. Foundries supplying pump bodies, valve housings and replacement parts lose margin and customer approvals when porosity, shrinkage, sand inclusions and misruns drive scrap and rework. Nominees run moulding lines, furnaces or casting inspection, and learn through inspection walkthroughs of moulds, melt records and defective castings. CoreConcept Training Center delivers this foundry and metal casting course.
Course Objectives:
- Assess a foundry's pattern, core, moulding, melting and finishing chain and locate where scrap and rework originate
- Control green sand and chemically bonded sand properties so moulds and cores resist erosion, penetration and gas defects
- Run melting, degassing, inoculation and pouring practice that delivers clean metal at the specified chemistry and temperature
- Design gating and risering systems that feed shrinkage-prone sections and keep metal flow free of turbulence
- Diagnose porosity, shrinkage, misrun, cold shut, hot tear and inclusion defects and set investment and die casting cell controls against them
- Build a Casting Quality and Scrap Reduction Plan with inspection acceptance criteria and foundry safety controls
Target Audience:
- Foundry management staff responsible for output, scrap rate and on-time delivery of cast components
- Casting process engineering staff responsible for methoding, gating, risering and process sheets
- Melt-shop supervision staff responsible for furnace charging, metal treatment and pouring
- Moulding and coremaking supervision staff responsible for sand systems, patterns and mould quality
- Casting quality engineering staff responsible for inspection, non-destructive testing and customer approvals
- Industrial localisation and supplier development staff responsible for qualifying cast pump and valve parts

Why Attend This Course:
- Deliver a Casting Quality and Scrap Reduction Plan for a case foundry to the foundry manager and the quality lead for approval
- Decide which casting route, sand system and feeding design suits a pump or valve component before tooling is ordered
- Avoid customer rejections, repeated weld repairs and lost melt capacity caused by porosity, shrinkage and sand defects
- Pass on the sand test log, gating calculation sheet, defect atlas and corrective action matrix to moulding and melt-shop teams
Conclusion:
Back at work, the participant presents the Casting Quality and Scrap Reduction Plan to the foundry manager, the melt-shop and moulding supervisors and the quality lead. The plan guides decisions on which defect families to attack first, which sand, melt and gating changes to trial, and which inspection acceptance levels to agree with customers buying pump, valve and replacement castings. After the first production month under the plan, the foundry should compare scrap rate, yield, rework hours and customer rejections against the baseline and update its corrective actions.
Frequently Asked Questions (FAQ):
What should participants know before the foundry and metal casting course?
Participants should already work in moulding, melting, finishing, casting engineering or casting quality. Basic familiarity with ferrous or non-ferrous alloys helps. A calculator is used for yield, gating ratio and riser modulus exercises, and anonymised scrap records or defect photographs from the participant's foundry make the walkthroughs more useful.
How does the foundry and metal casting course differ from a general manufacturing processes or steelmaking course?
This course stays inside the foundry: patterns, sand, melt treatment, feeding design, investment and die casting cells and casting defects. General manufacturing process courses compare machining, forming and additive routes, while steelmaking courses cover primary melting and continuous casting of semi-finished products.
Why does foundry and metal casting practice separate gas porosity from shrinkage porosity?
The two look alike yet have different causes. Gas porosity comes from hydrogen, moisture or turbulence and appears as smooth round holes, while shrinkage comes from unfed hot spots and shows rough dendritic cavities. Treating the wrong one wastes degassing or riser changes.
What do participants take back from the foundry and metal casting course?
Participants take back a Casting Quality and Scrap Reduction Plan for a case foundry, with a scrap Pareto baseline, sand and melt control checks, a gating and riser calculation sheet, a defect diagnosis atlas and a corrective action matrix they can adapt to their own castings.
