Casting Guides, Topic by Topic
Every guide below is written from how we actually run the plant at Arasur, Coimbatore — the same figures we quote from, not generic foundry theory.
New guides are added here as they are published. If something you need is not covered, email marketing@tcf.net.in and we will answer it directly, then write it up.
Casting Processes
Moulding routes, cores and how a part is actually made: high pressure, ARPA, shell and no bake.
How to Reduce Casting Lead Time: A Procurement Manager’s GuideWhen a casting supplier quotes a lead time, procurement should ask one question immediately: “Lead time to what?” Is it: Pattern completion? First poured casting? First…Read the guide
Casting Wall Thickness Design Rules: How to Design a Part That Actually Casts WellA casting drawing should describe more than the final shape of the component. It should provide a realistic manufacturing route from: Pattern → Mould → Pouring…Read the guide
Sand Casting Tolerances: What Dimensional Accuracy Can You Realistically Expect?When engineers discuss sand-casting tolerances, the conversation often starts with: “What tolerance grade can your foundry hold?” That is usually the wrong first question. A casting…Read the guide
Single-Site Casting and Machining: Why OEMs Are Moving Toward One Accountable SupplierA casting can be perfectly acceptable when it leaves the foundry and still become a rejected finished component weeks later. Why? Because the casting may travel…Read the guide
Gearbox and Differential Housing Castings: Design, Machining and Supplier Qualification GuideA gearbox or differential housing can pass visual inspection and still create expensive problems after assembly. The most common failures are often not dramatic casting fractures.…Read the guide
Wind Energy Casting: What Turbine OEMs Should Know Before Sourcing in IndiaWind-turbine castings do not fail because they look imperfect. They fail when decades of torque, bending, vibration and cyclic loading expose weaknesses that were already present…Read the guide
Off-Highway Castings for Heavy Equipment: Axle Housings, Wheel Hubs and Steering KnucklesOff-highway equipment operates in an environment where load conditions are rarely gentle or predictable. A tractor, wheel loader, backhoe loader, mining vehicle or other heavy machine…Read the guide
What Should You Look for in an Export-Oriented Foundry?Choosing the right export-oriented foundry is an important decision for any company sourcing iron or steel castings. The lowest quoted price does not always represent the…Read the guide
Automotive Casting Manufacturer: OEM Supplier Qualification ChecklistChoosing an automotive casting manufacturer is not the same as purchasing a general industrial casting. For an automotive OEM or Tier-1 supplier, a casting supplier can…Read the guide
Iron Casting: Types, Grades and How to Source the Right FoundryIron castings are used across some of the most demanding industrial applications—from machine-tool structures and automotive housings to pumps, valves, wind-energy components and heavy construction equipment.…Read the guide
Construction Machinery Castings: Swing Frames, Boom Brackets and Heavy Component SourcingConstruction and earth-moving equipment operates under conditions that expose components to repeated shock, vibration, fatigue, abrasive environments and high structural loads. For an excavator, loader or…Read the guide
What Is Metal Casting? A Complete Guide to Processes, Materials and ApplicationsMetal casting is one of the fundamental manufacturing processes used to produce complex industrial components. At its simplest, the process involves melting metal, pouring it into…Read the guide
Casting vs CNC Machining: When Near-Net-Shape Castings Become More Cost-EffectiveFor an OEM engineer or sourcing team, choosing between casting and CNC machining should not begin with the question: “Which process is better?” The better question…Read the guide
Understanding Ferrous Casting Costs: Grey Iron, Ductile Iron and Steel for OEM ProgramsFor an OEM sourcing team, choosing a casting material is rarely as simple as comparing the price per kilogram. A casting that looks cheaper at the…Read the guide
