Resin Coated Sand is manufactured by coating washed and graded dried sand grains with resin and hardener with lubricants by warm coating process. We use specialized design mixer for manufacturing with state of the art technology.
Shell moulding is a process where fine silica sand is coated with thermosetting resin. When this sand is brought in contact with high temperature metal pattern, it converts into the shape of the pattern, with high strength.
Foundry is a workshop that produces ferrous castings. Casting is a process where charge(metal scrap, C,Si,Mn, Cu alloys) is loaded in furnace and melted. Liquid metal is poured into a shell mould (based on the product) , afterwhich the solidification of metal takes palce, yielding the required product.
There are many ways of casting like green sand, shell mould, investment ,die casting and etc.
AAPL produces castings through 100% shell mould.
Machining is a process where material of part is removed using cutting tool to a desired shape and size
ADI is a material produced through a specialized heat treatment process applied to a base ductile iron. The ADI process involves high temperature homogenization of components followed by isothermal quenching into molten salt baths at elevated temperatures.
The completed process results in isothermal transformation – Ausferrite in Austempered Ductile Iron, Austempered Grey Iron and Bainite in steels.
Austempering is a high performance heat treatment that imparts superior properties to ferrous materials. At our ADI (Austempered Ductile Iron)facility, we produce -

2.HARDENING & TEMPERING
The primary aim of the conventional hardening and tempering process is to enhance the mechanical properties of the bulk material, producing specific combinations of tensile/proof strengths, hardness and ductility (impact strengths). The process involves careful heating to high temperatures, ‘soaking’ for specific duration, quenching in polymer or salt – depending on the material and requirements, followed by tempering of the hardened material to partly or substantially relieve quenching stresses and develop the particular properties required.
Annealing is a generic term covering a range of processes which can be carried out at a variety of temperatures. The primary purpose of annealing is to reduce the hardness of a material for subsequent machining. It also increases ductility and helps to eliminate residual stresses. Controlled temperature and controlled cooling is necessary to ensure the correct material structure.
