Vacuum Casting: Production-Grade Parts from High-Performance Silicones<\/h1>\n\n\n\n

Vacuum casting is the strategic choice for functional prototypes, pre-series, and specialised small series. By utilising a master model \u2014 often created via 3D printing \u2014 we produce reinforced silicone moulds that replicate complex geometries with extreme precision. This process allows you to achieve the tactile, mechanical, and optical properties of injection-moulded parts while avoiding the high lead times and costs of traditional tooling. <\/p>\n\n\n\n

Engineering for Every Requirement<\/h2>\n\n\n\n

We offer a diverse range of resins to match your specific mechanical and aesthetic needs. Our team provides individual advice to help you select the ideal chemistry for your application. <\/p>\n\n\n\n

\n

Polyurethane (PU)<\/h4>\n\n\n\n

Primarily used for housings, covers, and functional components. This material offers a balanced profile of strength and durability, making it the go-to choice for pre-series testing. <\/p>\n<\/div>\n<\/div>\n\n\n\n

\n
\n

Special PU Resins<\/h4>\n\n\n\n

For projects with demanding mechanical, thermal, or optical specifications. This includes transparent resins for lenses or heat-resistant resins for under-the-hood automotive applications. <\/p>\n<\/div>\n\n\n\n

\n

Silicone & Rubber<\/h4>\n\n\n\n

We manufacture seals, hoses, protective caps, and shock absorbers in a wide range of Shore hardnesses (10 to 85 Shore A). This allows for the production of soft-touch components or high-vibration dampers in small volumes. <\/p>\n<\/div>\n<\/div>\n\n\n\n

Customisation and Finishing Options<\/h4>\n\n\n\n

Vacuum casting delivers parts that look and perform exactly like final consumer products. We customise your components by adding glass fibers for extra strength or flame retardants for safety. You can choose from a wide range of colors to match your brand, including transparent or crystal-clear plastics. We also provide diverse surface textures such as professional spark-eroded finishes, spray putty, or high-gloss surfaces for a premium look. <\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n

Reinforced Tooling<\/h3>\n\n\n\n

The foundation of our vacuum casting excellence lies in our High-Precision Silicone Molds. While standard silicone tools often degrade after 20 cycles, we utilise specially reinforced silicone combined with high-strength additives to ensure superior results. <\/p>\n\n\n\n
