What challenges does polyurethane mixing create for gearbox manufacturers? 

\n\n\n\n

Polyurethane mixing has significant mechanical and chemical demands that are unique challenges for high performance chemical mixing gearbox manufacturers. PU mixing has high viscosity, and a need to monitor reaction times and changes in material state during mixing cycles with potential adjustments to mixing characteristics during production. 

\n\n\n\n

Appropriate shear forces need to be maintained throughout the polyurethane mixing process. This requires heavy duty, high power gearboxes that are extremely reliable, chemical resistant and very efficient. Off-the-shelf industrial gearboxes are not engineered for the intense demands of PU mixing, and this is why it is sensible to use a purpose-designed PU mixer gearbox if you want to get reliably uniform and consistent outputs.

\n\n\n\n

\n\n\n\n

What features should you look for in a PU mixer gearbox?

\n\n\n\n

Torque capacity, gear ratios, shaft sealing and thermal performance under continuous operation are all important factors when choosing a PU mixer gearbox. PU formulations include isocyanate and polyol compounds that can penetrate standard seals and etch gearbox housings, so high quality material and seal construction are essential features of gearboxes used in polyurethane mixing. 

\n\n\n\n

Well engineered polyurethane agitator gearboxes improve mix quality 

\n\n\n\n

Your polyurethane agitator gearbox needs to consistently perform with the correct rotational speed and torque output to ensure mix quality. Homogeneous mixing is essential to reduce the risk of batch failures. Well engineered polyurethane agitator gearboxes ensure homogenous mixing and better mix quality by being able to deliver high torque at the correct speed for your polyurethane mixing application.

How do you select a Transycko Gearbox for polyurethane mixing?

\n\n\n\n

There are four standard polyurethane mixing applications that require slightly different mixing equipment and gearboxes. Transcyko manufactures two gearboxes that are popular choices for polyurethane mixing, and have the rugged construction, impervious seal design and high torque that is required. Pictured above is a batch of our two-stage TSG-P2-V-C055-RL-22.4-CM-55KW polyurethane mixing gearbox undergoing final quality checks before shipping.

\n\n\n\n\n\n\n\n

Mixing flexible PU foam, used in furnishings and insulation, and PU coating mixing are comparatively high-speed, low-torque processes. Polyurethane elastomers and PU adhesives require high torque, slow speed mixing, and multiple stage speed reduction in the gearbox to achieve this. 

\n\n\n\n

The gearboxes manufactured by Transcyko for chemical mixing that are most suitable for polyurethane mixing applications are Transcyko TSG series helical bevel gear parallel shaft gearboxes. These are highly configurable depending on your requirements.

From our TSG gearbox catalog, our TSG-P2-V-C055-RL-22.4-CM-55KW two stage gearboxes (below) and TSG-P3-V-C060-RL-31.5-CM-55KW-A1 three stage gearboxes (shown above), are perfect for polyurethane mixing, with stages calibrated for the reduction required for higher or lower speed outputs. Both are 55KW rated and vertically mounted as standard, but full customization options are available.
