ProcessesofGrey Iron CastingsCommonly usedprocessforgrey iron castingsin the market is produced by sandcasting. Theprocessesusing sand as the mold media have a somewhat similar effect on the rate of solidification of thecasting, while the permanent moldprocesshas a very marked effect on structure and properties.

Normalising is theprocessof heating thegrey iron castingsto a temperature of around 885° to 925° C; soaking for a period of about 1h/25mm of the maximum thickness ofcasting; cooling in still air to room temperature. The microstructure of normalisedironconsists of pearlite and graphite flakes.
Grey iron castingsmade via thisprocesscan also be almost any diameter, length, and thickness. Diecastingis popular for continuous cycle or the fast production ofcastings. It uses reusable molds that are made in the shape of the desired finished product. To diecastthe metal, manufacturers must inject it into the die and apply pressure.

Iron Casting ProcessOptions. SandCastingis the most commonprocessfor makingironparts. Normally, these parts are big and high-tolerance. Besides, they do not require a good surface finish. If you are looking for a part like this, contact us and get thecastingwith the low cost.
Gray Iron CastingsFrom ounces to 5,000 poundsGray ironis selected for ease of machining, high compressive strength, better thermal conductivity and excellent vibration absorption.
Cast ironbegins its life as pigiron, which is remelted and often combined with large amounts of scrapironand sometimes with steel. Contaminants are removed from the melted pigiron, and theiron, once melted, is thencast.Castingis theprocessof pouring theironinto a mold thus giving it a shape.
Ourcastingscan reach up to 160 tons in weight forgrey ironand 60 tons for ductileiron. Each mold is engineered according to our customer specifications. Our products include ingot molds, slag pots, sprue plates, hot tops, and othercastingsused in the steel forgingprocess.

Ductileiron castingsare very strong compared to regularcast iron(gray iron). The tensile strength ofcast ironis 20,000 – 60,000 psi while ductileironstarts at 60,000 psi and can go to 120,000 psi. The yield strength for ductileironis generally 40,000 – 90,000 psi but the yield strength ofcast ironis so low it is considered not ...
Introduction. The first announcement of successful production of Spheroidal Graphite structures ingrey castirons was made by H.Morragh of Britishcast ironResearch Association in the year 1948 at the American Foundrymen”s society’s Annual convention in Phladelphia, U.S.A.Theprocessinvolved a treatment of low sulphur hyper- eutecticcast ironwith cerium, which was added as mish metal ...
This includes using superior engineeringcastirons like: flake graphite irons (Grey Iron), and nodular graphite irons (DuctileIron). Following the MeehaniteIron Casting Processallows Willman Industries to achieve uniform soundness, consistent physical properties and dependable service performance for all of ourcastings.
