Polyurethane casting is a simple yet effective method for making items of all different types, but in addition to having casting material, you also have to have molds that you can pour the polyurethane in. If you don't already have these molds or are ready to start shopping for them, then these tips will help you out. Whether you are working on a small polyurethane casting project or if you are going to be mass-producing items with your molds, the advice listed here should be helpful.
Look for Molds That Are Made for Use With Polyurethane
People pour all different types of materials into molds, but overall, you might be most interested in working with polyurethane. This can be a good thing since polyurethane can be a great material to work with. However, you should be aware that not all molds are ideal for use with polyurethane, so you will want to specifically look for polyurethane molds if you can. Then, you can make sure that you don't have any problems when using your molds. Fortunately, because polyurethane is such a good material to work with when you're making items with molds, molds that are designed to be used with this material are very popular.
Compare the Rigidity of the Different Molds
Even among molds that are designed specifically for use with polyurethane, there are different options. For example, some of these molds are very flexible, which can make them easier to work with but can also mean they aren't as durable. There are more rigid molds, too, if that is what you would prefer to work with. Make sure that you pay attention to the rigidity of different molds when you are buying them. If you're new to working with these molds, then you may want to try both rigid and flexible molds. Then, through trial and error, you can decide which type of mold will work well for you.
Remember That You Have the Option to Order Custom Molds
There are polyurethane molds of all different sizes and designs, so there is a chance that you will be able to find molds that will work well for whatever project you have in mind. However, depending on how unique your project is, there is also a chance that you will not be able to find molds that will work well. The good news is that you can actually order custom molds for use with polyurethane, so placing a custom order is always an option for you to look into.
