We will continue discussing the various factors that impact the pricing of Grey and Ductile iron castings in the concluding part of the blog series.  Section Size in an iron casting is an important factor that determines the parting line placement and the cooling time that is needed for the iron casting. If the section… Continue reading What are the common factors that drive the cost of Grey and Ductile iron castings – Part -2

Many a time if you are a casting buyer you may not view a casting in terms of the size and weight in the same way as an iron casting producer. There are several variables that can affect seemingly similar ductile and grey iron castings in different ways. This blog will cover the most common… Continue reading What are the common factors that drive the cost of Grey and Ductile iron castings? – Part 1

VR Foundries feels happy talking to you all through the company’s official blog, the least we can do staying at home. Yes, we are in the midst of an outbreak of a deadly crisis called COVID-19 or Novel Coronavirus that has shook not just the world, but shattered the hopes of billions of people throughout… Continue reading An Update From VR Foundries Owing To COVID-19 Crisis

As the impact of Coronavirus continues to haunt the casting’s industry, there are a few things that the Indian casting industry can do to mitigate the crisis from a business perspective such as manufacturing disinfectant stands from aluminium, among other materials, with a reduced workforce and use of novel technologies. From an application point of… Continue reading Coronavirus Impacts Casting Industry – Part 2

The impact of the ongoing COVID-19 or the Novel Coronavirus has had a spiral effect on almost every sector globally. Businesses are clueless as to how to tackle its impact on day-to-day operation. With unprecedented lockouts and stalling of business operation, the world is attuning itself to ‘new’ normal as never before. The metal industry… Continue reading Coronavirus Impacts Castings Industry – Part 1

In the water engineering industry, ductile iron pumps, as discussed in the previous blog, have been proven to display improved corrosion and heat resistance. Because it has a coefficient of thermal expansion of 7, it prevents thermal expansion of several parts of the pump including head bushing in the casing and rotor bearing sleeve, and… Continue reading A Note On Why Ductile Iron Is An Innovative Technology – Part 3

Pig Iron goes in as raw material, which is low in phosphorus and sulphur, that is imperative without which the desired product cannot be achieved. While tin and copper added provides tensile strength and ability to withstand shock, silicon helps in the formation of graphite which offers iron the much needed non-corrosive property. The ductile… Continue reading A Note On Why Ductile Iron Is An Innovative Technology – Part 2

Ductile Iron is also known as Nodular Cast Iron or Spheroidal Graphite Iron. Rich as graphite cast iron, it throws a wide range of applications. Keith Dwight Millis is credited for the discovery of this product in 1943. The US patent for its commercial production was obtained by Keith Dwight Millis, Albert Paul Gagnebin and… Continue reading A Note On Why Ductile Iron Is An Innovative Technology – Part 1

Let us begin from whrayere we left in the previous blog. Grey Iron Sanding casting exhibits low level of elongation values that leads to large amount of stress on the casting that is poorly designed. How can stress be measured?There is only a sure-fire method of determining stress levels in a casting under load and… Continue reading Three Important Points on Grey Iron Castings – Part 2

There are three important features of designing with Grey Iron castings. Often what comes as an after–thought is the use of Shrinkage while designing. In comparison with Steel or Ductile Iron for castings, Cast Iron or Cast Iron can be easier and simpler to work with. This is due to reduced solidification shrinkage rate compared… Continue reading Three Important Points on Grey Iron Castings – Part 1
