  1. What is Vacuum Mold Casting and Its Purpose? Many product designers, manufacturers, and engineers will want to cut costs when creating a prototype, but that can be challenging as there’s the risk of compromising the quality and performance. Vacuum mold casting can be an excellent option to avoid those issues as it produces quality parts without the lead time and costs required in production tooling. The process is similar to duplication with a silicone mold. Vacuum casting works on products of any size, making it possible to build anything from car bumpers to headphones. Reputable manufacturers offer a range of materials to suit every requirement so that you can get the most from the service. How does it work? Vacuum casting or urethane casting involves three stages: 1. Master model creation – The master model is 3D printed using SLS (selective laser sintering), stereolithography (SLA), or CNC machined. 2. Crafting the silicone tool – When the master model is ready, liquid silicone is poured around it and left to cure. Once dry, the master is cut from the mold, leaving the cavity. 3. Casting – Resin is poured into the cavity to create the production-grade replica. Purpose Vacuum mold casting can be an efficient and economical alternative to injection molding, especially when you require intricately detailed and complex products. It is widely used in commercial product prototyping and manufacturing of consumer products, food and beverage vessels and utensils, and electronics. Polyurethanes have excellent heat and shock resistance, making them ideal for a wide range of applications. Advantages Vacuum mold casting requires a low upfront investment, and it generates production-like, self- colored parts from a massive range of materials. It is cost-effective for low-volume production and

  2. prototyping, rapid iterations, and market testing. The process makes it possible to recreate tens of identical parts with production-grade materials. Is vacuum casting for you? Consult a reputable and experienced provider of vacuum mold casting services for design tips and advice. Make sure they offer other manufacturing and prototyping solutions, such as 3D printing and injection molding, so you don’t have to look further.
