You use epoxy resin casting moulds to shape resin for projects. Sometimes, resin gets stuck in a mould. You may also see bad details on finished pieces. This can happen if you choose the wrong mould type or material. Silicone moulds help stop these problems. They are flexible and have non-stick surfaces. Many crafters use special moulds for casting resin. Some use deep pour moulds or custom moulds. You should match your mould to your resin and project needs. This helps you get the best results. Key Takeaways Pick silicone moulds if you want smooth resin pieces. They bend easily…
You might ask how much vacuum casting costs in 2026. The usual mold price is between $200 and $1000. Each part often costs from $10 to $100. Many things can change the price. These include the material you pick, how complex your part is, and what finishing you want. Vacuum casting is a good choice for making a few items. It costs less per part than injection molding for small batches. Silicone molds are quicker and cheaper to make than using machines. Making a small number of parts works best for prototypes and working pieces. This vacuum casting price guide…

Accurate measurements stop you from wasting silicone and help you calculate silicone volume for mold effectively. They also ensure your mold works correctly. You can find silicone volume using a simple formula: Required Material Volume equals Mold Container Volume minus Model Volume. For regular shapes, use these formulas: ShapeFormulaSquare/RectangleVolume equals length times width times heightCylinderVolume equals π (3.14) times radius squared times height Follow these steps to get the right amount of silicone each time. Key Takeaways It is very important to measure carefully. Measure your mold container and model two times so you do not make mistakes. Use the…
You may wonder if silicone vacuum casting and 3D printing costs are more favorable for your project. This is crucial when you require silicone molds or prototypes. The true answer hinges on the quantity of parts you need and their intended functionality. If you only need one or two pieces, 3D printing is typically the more economical option, and it also delivers your parts more quickly. However, if you require a larger number of parts, the silicone vacuum casting and 3D printing costs will vary. Here’s a quick comparison to help you understand how they stack up: FactorVacuum Casting3D PrintingTooling…
When you pick the best silicone for prototype molds, Shore A hardness is important. Shore A shows how soft or hard the silicone feels. It goes from very bendy to very stiff. This scale helps you choose a silicone that fits your project. Softer silicone is good for tiny details. Harder silicone lasts longer when used a lot. Here is a quick look at common Shore A values: Shore A HardnessDescription10°Very bendy, for special uses20°Soft, like a rubber band40°Bendy, like a pencil eraser60°Good for tubes and gaskets70°Tough, like tire tread80°Hard, can take the place of plastic You can find top…
