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 worth taking the time 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 great 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 to operate them are the major differences between conventional and multi-slide die casting.

Dynacast Tooling

Conventional die casting uses a two-part tool where multi-slide uses at least four perpendicular slides. Using more slides makes reduces variations 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 formed together, the molten metal is injected into the cavity and the part is cast.

Engineers and designers are always pushing the envelope with part designs wanting 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 cast machines; however, the multi-slide tools are second to none when it comes to consistency and accuracy.

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

To ensure longevity of our dies, our tool designers predict what part of the die may wear out and insert this as a separate piece of the tool so that we can easily replace one single part, rather than the whole tool when it wears out. This not only saves our customers a great deal of money, but it also ensure that we can get your project back up and running faster than if we needed to create a new die entirely.

Proprietary Die Cast 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 are capable of filling machines faster without heavy flash, which improves surface quality and decreases the porosity of parts. Our multi-slide machines make it possible for us to produce parts in mass quantities while still ensuring the best quality.

Over time, machines age, parts wear, and technologies can become outdated. We build all of our machines in house, so our team of experts is constantly upgrading and making improvements to both our multi-slide and conventional die casting machines as well as the controllers that run 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 are always updating and optimizing our tools and machines to provide our customers with the best parts possible.
