Which materials can be processed?
The Hauschild SpeedMixer® units of the DAC series are suitable for the mixing of one-component and two-component silicones, polyurethanes, polysulphides, acrylates and many other materials. Many products not included in this listing can certainly profit from the technology of the Hauschild SpeedMixer® As a result of the use of one-way containers, the danger of any contamination of paint master batches, pharmaceutical products or other sensitive materials is avoided, since no mixing components have to be cleaned in the devices. Both reusable containers, as well as more low-cost one-way containers, are available (which are to be recommended in particular if cross contamination can present a problem). The respective the Hauschild SpeedMixer® units of the DAC series also process greater filling-material quantities than the conventional mixing systems, e.g. 25% or more pyrogenic silicic acid in a silicone!
Which quantities can be mixed?
According to the device, charges extending from a few grams up to a highest weight of 3000g can be mixed. The containers are employed with supports whose weight is designed so that the devices retain their equilibrium. Different container sizes are available (PP 5, 10, 15, 30, 50 and 100 g) in order to conform to your requirements and to minimise material requirement, where the actual batch size is tailored to the quantity required by you, and not to the requirements of the device.
Where are these devices employed?
The main applications are currently in research and development, in quality assurance tests and small-quantity production lots. With the incredible mixing and dispersal speed, sealing compounds, coating materials, plastisols or adhesives can be manufactured in less than 10 minutes! The weighing procedure currently presents a challenge, not the mixing/dispersal. With the Hauschild SpeedMixer® the user also has the advantage that many repetitions can be manufactured which could not be tested with other systems for reasons of time. The Hauschild SpeedMixer® units of the DAC series have proved useful for developments for which tests are to be implemented with regard to hardening, colours, consistence and appearance, as well as measurements of physical properties. Numerous formulations can be checked prior to any further development phase. With the Hauschild SpeedMixer® technology, there is a suitable container for every mixture to be created.

How can I check the speed of the device in order to avoid damage?
The devices of the DAC series were designed especially for the research and development sectors. Their speed is variable (300 - 3,500 rpm, adjustable using a rotating switch). In addition, speeds can be adjusted using the keyboard, avoiding use of the focusing screen, in order to process a series of charges with the required speed. With lower speeds, some effects of the strong centrifugal forces which act at high speeds can be avoided, e.g. the formation of frictional heat in sensitive mixtures or the possible damage of microenvironments.
