Cast Iron Weights – Weight Production for Fitness

Iron foundries, like those run by Faircast Inc., play a much more significant role in our daily lives than many people realize. Most people have a particular image in their minds when they hear the term ‘foundry’ – large men in hardhats with big black rubber gloves in sweltering environments, pouring out giant cauldrons of molten metal. Maybe people think of them as producing things like giant iron girders used to build skyscrapers, or perhaps making massive hulls for freighters and aircraft carriers. However, the iron produced at our foundries can be found in many other places around the world, sometimes just around the corner or even in your spare room.

What am I talking about? Weights, of course. Good, old fashioned cast iron weights; lifting heavy things and putting them back down repeatedly for the purpose of building muscle. Iron has been a part of basic fitness regimes since there has been such a thing. From the ancient Olympic games, when you might toss an iron-tipped javelin to modern CrossFit training slinging around an iron kettlebell, iron has been there. There have been all kinds of different attempts to create new fitness methods like some based strictly on calisthenics, resistance bands, walking, swimming, and who knows what else. One constant remain, if you want to build muscle, you’re going to need to lift heavy things, and they are probably going to be made of iron.  This is true whether you are working out at home using simple dumbbells from the local Walmart, or going to your area gym full of fancy machines with all sorts of cables and pulleys. At the end of those cables is a stack of simple cast iron plates and weights, whether you go to a small storefront gym, a massive fitness club with every service that you can think of, or a professional gym for bodybuilders and athletes.

Because of this, the fitness world generates a lot of business for iron foundries like Faircast. Whether it’s a kettlebell, traditional dumbbell, a circular plate for free weights, or a simple rectangle for the machines, cast iron weights are easy to make. They use the same very simple molds over and over again, with little variation. Usually, the only real change to a mold is based on whether or not the particular brand has a specific design to the weight or a logo that needs to be incorporated into the casting. Otherwise, logos can just be stamped or etched into the end product. That simplicity and repeatability make the production of iron weights very cheap as molds and production lines do not need to be reconfigured often. These weights also do not need to be made of the highest quality iron either. They aren’t taking the punishment of a railway track; they don’t need to undergo the constant stress of holding up a building or deal with the many moving parts or rapid temperature swings of an engine block. They are just a ball, a circle, or a rectangle of metal that gets picked up and put back down a lot. Since the environmental stresses on iron weights are so small, they can be made of iron that might be rejected for some of those other purposes, allowing foundries to make the most use of all the metal that gets shipped into them. Not only does this reduce costs and increase profits, but it also keeps waste down as well.

Iron foundries also contribute to the fitness world by building some of the machines that we mentioned earlier. These have to be built sturdy enough to take the kind of punishment they will get from repeated use (especially if they are going to one of those higher-end gyms at the universities and professional sports organizations) and still lite enough to move around whenever there is a need to change the floor plan, not to mention getting it into the gym in the first place. For that, iron is a perfect solution. Hollow framing that it still easy to cast and weld provides just the right balance of strength, durability, and weight to satisfy the needs of the home and the professional gym.
