Newbie Question
I am very new to the casting industry and I have just taken a position to where I am buying all of the castings for my company. Are there any tips or tricks that you can give me?
For quoting purposes, a model is, of course, the best way to ensure a quick quote. However, if that is not possible, a 2-dimensional drawing and a weight along with the material are sufficient. At minimum, it is necessary to have the weight, outer dimensions, and the complexity and cores necessary, or a few photographs of the part. If possible, a sample we can look at in person is appreciated.
As far as material determination, that is primarily decided based on application and complexity of the part. We at Astech deal with hard materials on a regular basis, and therefore have the equipment and knowledge to deal with tougher steel grades. Most parts that were mild steel fabrications can easily be turned into a higher alloy steel to increase strength, and it is actually easier to pour some of these higher alloys than a mild steel. Stainless steels are determined by environment and usage. Corrosion resistant grades have a lower hot strength, while high temperature grades are more susceptible to corrosion, with various grades between. Beware, however, going over the top for high-temp alloys, as they get expensive quickly, so if you don't need that kind of temperature resilience, it is not worth the money. White iron and manganese steels are used almost exclusively for wear parts, since white iron has such a low impact toughness and manganese corrodes as easily as mild steel.
