Even though the field of rapid prototyping has expanded greatly, many product designers and engineers continue to rely on trusted technologies such as vacuum casting. Vacuum cast parts are high-quality prototypes that not only facilitate the progress of product development but are also suitable for small-scale production of final parts.

Vacuum casting is a flexible technique that can be used alongside other methods like 3D printing and CNC machining to yield the best results. Regardless of its application, this process allows you to create production-grade parts without the lengthy wait times and high costs associated with traditional production tooling.

Are you making self-colored, production-grade, and identical parts? Your project could greatly benefit from vacuum casting. Technological advancements and innovations make it possible to vacuum-cast parts of any size, allowing product designers to make anything from vehicle parts to plastic storage boxes, trays, headphones, and medical devices. That said, be sure to work with an experienced service provider with up-to-date knowledge and technologies to deliver your parts accurately, quickly, and cost-effectively.

More material options

One of the most significant innovations in vacuum casting is the availability of more polyurethane resins with the same features as thermoplastics. Top service providers can build production-like parts out of materials similar to ABS, PA, PC, PP, or PMMA. Some parts can also have additional properties like flame retardant or transparency. Additionally, it’s now possible to cast parts from transparent soft rubber and finish them with techniques like polishing, sand-blasting, plating, or plating.

Cast small and large parts

Reputable service providers can vacuum cast parts up to 2300 x 1000 x 400mm in size. They guarantee accurate results by controlling tolerances to +/- 0.1mm/30mm or +/- 0.5mm, whichever is greater. Undercuts are not an issue with vacuum casting, so there is no need for inserts during the process. Additionally, it’s possible to add embossed or recessed logos or text on the parts, as long as they are no more than 1mm wide, deep, or high.
