Hauschild SpeedMixer
The Original Pioneer of Centrifuge Mixing

Say YES to an Authentic SpeedMixer - Choose The Genuine SpeedMixer Trusted Globally

LR Series DAC 400-1100

The Hauschild SpeedMixer® LR series, first introduced in 2014, is widely used to mix silicones, epoxies, urethanes, ceramic & battery slurries, pharmaceuticals, and many other materials. This series is also available with the ability to vacuum degas while mixing or mix under inert conditions. Its Modern geometry, high main RPM, programmability, and configurability/compatibility with accessories make a versatile laboratory mixer. These features also give the equipment the precision, repeatability, and process control needed to handle specialty production applications.

Top Features

Dual Asymmetrical Centrifugal (DAC) mixing – A closed disposable container is rotated around a primary axis. The container is simultaneously counterrotated around on its own Y axis, creating a powerful mixing vortex. This result is fast, homogeneous, repeatable mixing and bubble removal.

The machine’s touchscreen display makes it easy to set, save, and lock programs. This ensures that precisely optimized mixing and degassing methods can be accurately and repeatably reproduced. With minimal training, any operator can achieve exactly the same results. The optional PC interface software allows remote control of the equipment full documentation of all mixing activities for traceability purposes.

VAC series Hauschild SpeedMixer® equipment features the ability to pull and regulate vacuum throughout the process. This removes microbubbles, dissolved air, and can even strip volatile content or purge solvent. The centrifugal motion combined with constant exposure of new surface area makes the process much faster than conventional vacuum degassing methods. It also helps prevent messy boil-overs. The equipment is compatible with any vacuum source and will automatically power & control vacuum pumps up to 700W.

Case Study

Hauschild SpeedMixer® DAC 600.2 VAC-P LR Helps Defense Customer Eliminate Bubbles and Improve Adhesive Properties

The SpeedMixer to Trust.

A defense customer was experiencing issues with their LOCTITE® EA 9396TM AERO adhesive. The adhesive was prone to slumping or flowing off the part before it could be cured. To address this issue, they started adding a small amount of fumed silica to the adhesive. Although this prevented the adhesive from slumping, it led to the formation of bubbles during the heat-accelerated cure process due to air being incorporated by the rheology modifier and mixing process. The customer needed to find a solution to prevent the formation of bubbles and improve the dispersion of fumed silica while also providing the operators with additional working time.

Undermixing: Because hand-mixing is a common practice, undermixing is a common issue with epoxy-based adhesives. Multi-component adhesives require a thorough mixing to ensure homogeneity and that the material cures/reacts properly. The Hauschild SpeedMixer® uses a high-speed DAC mixing action to quickly and effectively homogenize the adhesive components and any additives, if used.

Bubbles: Bubbles can form in epoxy-based adhesives during a conventional mixing process, which can weaken the bond and reduce the adhesive’s overall performance. The Hauschild SpeedMixer® uses DAC mixing with or without vacuum to remove air bubbles, ensuring that the adhesive cures properly and forms a strong, durable bond.

Volatile Content: Volatile content refers to any solvents or other volatile compounds that are present in the adhesive mixture. These compounds can expand and form bubbles during the curing process, leading to voids and weak points in the adhesive bond. The Hauschild SpeedMixer® uses a vacuum degassing step to remove unwanted volatile content that could create bubbles during the cure, or potentially outgas and cause issues in space based applications.

Dissolved Air: Dissolved air can also weaken the adhesive bond, as it can cause bubbles to form during the curing process. The Hauschild SpeedMixer® uses a vacuum mixing technique to remove dissolved air from the adhesive mixture. This ensures that the adhesive cures properly and that the cure process can be accelerated with heat without creating bubbles.

The implementation of the Hauschild SpeedMixer® DAC 600.2 VAC-P LR provided the customer with several benefits. The new standardized and automated process eliminated the formation of bubbles during the heat-accelerated cure process, resulting in the elimination of costly re-works and scrap parts. The improved dispersion of the Aerosil resulted in a stronger bond between the adhesive and the part. Additionally, the operators were provided with additional working time, allowing them to complete the process more efficiently.

The operators also noted that they liked that the new process didn’t make any messes, and there was nothing to clean after mixing. This saved time and increased the efficiency of the overall process.

Unmatched Laboratory Mixing Innovation

Secondary features and benefits - value

Best in class performance, reliability, and value

Since inventing the technology in 1974, the team at Hauschild have been engineering and manufacturing with a focus on quality, performance, safety, and reliability. Hauschild SpeedMixer® equipment is known for being the most powerful, versatile, and safe lab mixer / specialty production mixer available. It is also one of the few planetary centrifugal mixers that has been proven in the field to last for decades with minimal maintenance.

Saves time & material – Protects the workforce

The Hauschild SpeedMixer® mixes quickly and is compatible with a variety of single use mixing cups. This saves time associated with mixing, as well as time, solvents, and other materials associated with cleanup. Unlike blade mixers, DAC mixers offer the ability to size batches/mixing containers based on what is needed for testing. This eliminates significant material waste.
Conventional mixing equipment & methods present several hazards to the workforce such as exposure to material, exposure to cleaning solvents / solvent vapors, and risk of repetitive strain injury (RSI). An automated mixing process utilizing Hauschild SpeedMixer® equipment, along with proper PPE and material handling practices, protect the operator from these sources of danger and can help reduce the rick of a Lost Time Injury (LTI).
