Multi-Slide vs. conventional die casting

Our Multi-Slide die casting process was originally invented in 1936. Since then, we have continued to improve our tools and machines. If you are using a conventional die casting process, it may be worthwhile to understand how Multi-Slide works and how it could be a better fit for your project. If your part is less than 400g, Multi-Slide is usually the better option. Conventional die casting is suitable for larger parts that do not fit in our A2 or A3 machines. The construction and operation of the tooling and the types of machines used are the major differences between conventional die casting and Multi-Slide die casting.

Dynacast tooling

Conventional die casting uses a two-part tool, whereas Multi-Slide uses at least four perpendicular slides. Using more slides reduces variation and is more cost-efficient when producing smaller parts with more complex geometries. Each die block has a cavity or a core on its face. When assembled, molten metal is injected into the cavity and the part is cast.

Engineers and designers continue to push design boundaries, seeking smaller, more complex parts that perform multiple functions; our Multi-Slide die casting process is the best option if your part is 400g or less. We can still create precise parts with our conventional die casting machines; however, Multi-Slide tools are second to none in consistency and accuracy.

Regardless of the process, we always focus on die design, incorporating as many part features as needed to avoid secondary operations. Our goal is to achieve net-shape on the first attempt, every time. This careful planning eliminates the need for machining and reduces the overall part cost.

To ensure the longevity of our dies, our tool designers predict which parts of a die may wear out and insert these as separate tool components, allowing us to replace a single part rather than the entire tool when it wears out. This not only saves our customers substantial costs, but also ensures that we can get your project back up and running faster than if we needed to create an entirely new die.

Proprietary die casting machines

Our unique Multi-Slide machines are only available within Dynacast. Upgraded machines are now equipped with thrusters that have a flexible crosshead adaptor system and a fast pneumatic injection system. We can fill machines faster without heavy flash, improving surface quality and reducing part porosity. Our Multi-Slide machines enable us to produce high volumes of parts while maintaining the best quality.

Over time, machines age, parts wear, and technologies can become outdated. We build all our machines in-house, so our team of experts constantly upgrades and improves both our Multi-Slide and conventional die casting machines, as well as the controllers that operate them.

Multi-Slide die casting

Our Multi-Slide process is the best die casting option for small, complex parts. We can create net-shape parts, typically without secondary operations—including internal and external threads. We continually update and optimise our tools and machines to provide our customers with the best possible parts.
