A cost-efficient method for rapid production of small series and design/functional prototypes – as an alternative to the conventional injection-molding process.

Vacuum casting is an established process for fast and cost-effective duplication of master models. With the help of the master models, a silicone mold is created which enables multiple identical parts to be cast in polyurethane casting resins. The use of a vacuum chamber prevents air inclusions in the mold and workpiece. High-end-coated silicone tools reinforced with additives increase the accuracy of the vacuum castings, reduce delivery times and are immune to wear. Thanks to this innovation, we can produce an almost infinite variety of parts from silicone molds instead of the usual 15 to 20 pieces. This closes the gap to series production. Therefore, when using standard PU resins you only pay the initial costs once at 1zu1.

We focus on series plastic materials and currently use a wide range of different resins. These include hard plastics (reinforced/non-reinforced) to transparent parts and elastic rubber or silicone moldings. However, food-grade and FAR25-certified resins (self-extinguishing in accordance with the former standard UL-94 V0) are also available.

Through our process innovations, range of materials and experience, we ensure you are left holding all the aces:

Quality advantage
A new silicone treatment and improved polyurethane resins ensure the renowned 1zu1 precision for each and every casting.

Cost and quantity advantage
You only pay for one mold, even for repeat orders – up to 1,000 parts.
A 1zu1 exclusive: One mold can be used to cast up to 1,000 pieces in standard PU resin. Gone are the days when a new silicone mold was needed after production of 15 to 20 parts.

Service advantage
Technical review of the components, design review, construction and assembly options as well as functional tests.
