What’s the Difference?
So, you’re looking to cast a few molds this but not sure where to start? There are tons of molds in the market that range in quality, price, and shelf life. You don’t have to be an expert or have a chemistry background to create unique molds. Understanding some of the basics will help ensure your weekend DIY project be a fun one.
ABS injection molds are quite possibly the most popular types of molds in the market. 75% of indoor and outdoor molds you see, such as skulls, wall plaques, and the always popular breeze blocks, due to their high impact strength and durability. In addition to strength, ABS molds are known for their resistance to extreme heat, oils, acid, and weather. The proper pour is essential for casting ABS molds. You can’t have too much water, and your mix has to be just right to bring these molds to life. Our ABS plastic molds are ideal for cement-based materials, plaster of paris, and two-part foams. Epoxy resin materials are not compatible with ABS molds.
Resin molds are no different than ABS molds in the sense that the same mixing technique is critical, but you’re not pouring cement to create these molds. A casting resin, mold, and the object you’re aiming to preserve.
Silicone rubber molds offer great flexibility, can be used in high temperatures, are considered non-toxic, and no release agent is needed in most cases. Our molds are handmade using high-quality addition-cure silicone, which offers exceptional heat resistance and has a longer lifespan than tin-based silicone molds. Liquid silicone resins are used to create heat-resistant products such as spatulas, cookie trays, ice cream molds and are ideal for everyday use. One downside to silicone resin molds is that they require a lot more care and must be cleaned after use and stored flat in a cool and dry area.
