      Dental applications – Innovation meets quality

      The starting point – Improving material, design and functionality To optimize minimally invasive caries treatment using highly fluid infiltrating resin, DMG sought a new manufacturing partner to redesign the existing syringe and its seals. The goal was to find a new material for the sealing plug, redesign the seal, and improve functionality. DMG contacted toolcraft for development and component manufacturing. The Challenge – Meeting highest standards for medical parts The material had to be compatible with the infiltrating fluid and provide the required Shore hardness for sealing. Tight tolerances for fits were critical. The biggest challenge was thermal management in 2K injection moulding due to the large temperature difference between the PBT hard and TPE soft components. Cycle time optimization and maintaining high medical quality standards were also key. The Approach – Comprehensive consultation and support every step of the way Consulting on material selection and design, developing designs for four parts in three plastics (2K PBT, TPE, 1K LSR), building two moulds and production of the injection moulded parts. Components were robotically removed, singulated, and quality checked (including CT scanning). A mounting fixture was designed and built to assemble the parts. The Result – Automated manufacturing and quality assurance Thanks to toolcraft’s expertise, production, assembly and CT-based inspection were automated and components optimized. From design to production, teams from toolmaking, injection moulding and robotics ensured seamless customer support.

      Design and development

      From conception to a design ready for production At the concept stage, we use 3D design techniques to test whether our concepts can be replicated in a tool, and we achieve innovative results by pooling together all our knowledge of development, tool construction and production. If necessary, this will involve prototypes or small trial series using STL models and aluminium tools. This gives us valuable insights into subsequent series production. Our design department consists of five modern CAD workstations – this is where product designs and the corresponding injection moulding tool designs take shape. A further three CAM workstations are available to convert the CAD files into programmes for the tool machines.

      Design and in-house tool construction

      From the idea to the finished injection-moulded part. Right from the initial development phase of a project, our team is working hard creating a production-ready design for your component, selecting the optimum material and developing the perfect tool design for your component. A uniform CAD-CAM system gives our designers and programmers the ideal platform for designing and constructing your tool. From day one, you have a contact partner who will see your project through from concept stage right through to series delivery.

      Designing

      The production of each tool begins on paper or on the computer. We plan and think everything through very carefully in order to be able to deliver a perfect product at the end. This means that the engineering of the injection moulding tools takes place in our own company. In more than 20 years, we have seen a lot, gained extensive experience and are able to meet the highest demands. In the field of design, we also work with the most modern means in order to maintain the constantly increasing level of requirements. The CAD software "Cimatron" as well as the coverage of a multitude of different interfaces enables us to work precisely and flexibly.
