We have the ability to internally develop and produce a wide variety of proprietary material formulations at our three mixing centers located around the globe.
This region is served by our Mixing Center in Keokuk, Iowa. This is a state of the art facility having two 250L intermeshing rotor mixing lines dedicated to the mixing of EPDM. Features of these lines include:
- Latest design intermeshing rotor internal mixers which has been proven to be optimal for mixing EPDM compounds
- Fully automated mixer control for batch to batch consistency
- Automatic weighing and delivery of fillers and oils
- A flexible multi-mill downstream system to maximize efficiency on both single pass and two pass mixing
- Cold room storage prior to delivery
The mixing unit is also supported by real time testing in a dedicated control laboratory.
In addition to mixing EPDM our Keokuk, Iowa mixing center has a twin screw mixer for TPE with a unique material feed arrangement taking advantage of its location as part of an EPDM mixing facility.
We have also developed a relationship with a custom mixer who is able to successfully reproduce our in-house formulations both as an insurance of continuity of supply and as a source of compounds for our manufacturing plants in Mexico.
In Europe we have a tandem mixing unit located in Rehburg. This utilizes a pair of Intermeshing rotor mixers running in sequence to achieve similar efficiencies on two pass mixing to those achieved by the multi-mill unit in North America. Mixer controls and material delivery are similarly state of the art as is the laboratory facility.
We also have a relationship with the same custom mixer for additional capacity.
In China we have an intermeshing rotor mixer located in Beijing which mixes first pass only. A better solution to the logistics in China is to have a second pass mixing unit in each of the extrusion plants. This avoids potential problems associated with long transportation distances and times. In Beijing this second pass unit consists of a low intensity internal mixer with associated mills, elsewhere we use mill units.
