PATTERN DESIGNING -MAKING AND INSPECTION

At Gujarat Intrux all patterns are match plate mounted in the sampling stage itself which leads to consistent quality castings.

SAND DRYING-MIXING AND TESTING

For the better process control at Intrux we used dry sand. The sand testing lab equipped with compressive permeability, friability, sieve analysis and clay testing equipments. At Gujarat Intrux we take 2 samples per shift and measured for moisture, compactibility, permeability and green strength.

MOULD AND CORE MAKING

At Gujarat Intrux we make mould with semi- automatic loop line which leads to high accuracy of dimensions tolerances related to statistical error. For mould making we use Co2 process and for core we use Co2 as well No back process.

MOULD INSPECTION AND COATING

As a final inspections of mould and core, it must be smooth, free of loose sand or projections before they are sent for coating. Liquid metal penetrates the pores of the sand mould or core giving a rough surface to the castings. A refractory coating on the mould or core will give a good surface finish to castings.

MOULD AND CORE ASSEMBLY

Cores are positioned in the mould by core prints. Good core setting involves advanced planning so that the cores will be perfectly and firmly held when the metal is poured.

CASTINGS

The mould after core assembly and inspection are ready for pouring and prepares it to receive the specified alloy. The mould is filled to the required level and left to solidify.

MOULD KNOCK OUT

When filled metal with mould are fully cooled, the sand is removed mechanically from the cast assembly. All cast parts are then removed from the runner system by gauging and gas cutting.

FINISH

Gujarat Intrux offers a choice of finishes and appearance achieving by using a variety of blasting techniques and chemical process.
