crafting unique chocolate delights: 3D design and SiOCAST rigid molds

case study:

De Tinnen Ross (DTR) in collaboration with Chocobreak and Hertog Jan - crafting chocolate masterpieces with SiOCAST.

In the world of custom chocolate manufacturing, innovation can be the sweetest ingredient. Dive into the success story of De Tinnen Roos (DTR), one of our valued casting service customers, as they partnered with Chocobreak.com and the renowned Netherlands beer company Hertog Jan to create something truly exceptional. 

 a sweet collaboration takes shape

Hertog Jan had a unique idea – to produce a limited edition of chocolate bars to accompany their premium beer offerings. These chocolate bars were not your average confections; they were designed to complement the distinct flavors of their beers. To bring this vision to life, Chocobreak needed a lot of custom molds that were both intricate and cost-effective. DTR offers a solution for making chocolate rigid mold with SiOCAST technology. 

the SiOCAST advantage

Enter SiOCAST - the catalyst that transformed Hertog Jan's vision into reality. De Tinnen Roos (DTR) harnessed the full power of the SiOCAST ecosystem, including our revolutionary mold-making system, compact SiOform1 injection machine, and specially formulated SiOres material. The results were nothing short of extraordinary.

In this remarkable case study, we accomplished an impressive feat in production times:

  • 1 day for 3D printing (SLA/DLP/LCD printers)
  • 2 hours for mold creation and vulcanization with the SiOpress
  • An astonishing rate of one chocolate mold produced every 2 minutes with the SiOform 1

At SiOCAST, our innovative technology not only transforms the manufacturing process but also significantly reduces production times, allowing you to bring your creative visions to life with unmatched speed and efficiency.

speed meets customization

With SiOCAST, DTR was able to manufacture hundreds of custom molds quickly and efficiently. The traditional mold-making process would have been time-consuming and costly, making it impractical for this project. Having dozens of SiOCAST injection molded molds helped the chocolate master Chocobreak (chocobreak.com). SiOCAST's unmatched speed and cost-effectiveness allowed DTR to bring Hertog Jan's unique chocolate bars to market in record time.


DTR's collaboration with Chocobreak and Hertog Jan demonstrates how SiOCAST is redefining the possibilities in custom mold manufacturing. By leveraging the speed, flexibility, and cost-effectiveness of the SiOCAST ecosystem, DTR turned an innovative concept into a delectable reality. This success story is a testament to the transformative power of SiOCAST technology in the world of chocolate and beyond.
