 Model LME Laboratory Mixing Extruder
The Polymer Test LME Laboratory Mixing Extruder is a unique laboratory tool developed to evaluate the processability of a variety of plastics and rubbers prior to production. From very fine powders to coarse materials, the LME will meet many extruding needs.
The LME possesses a moveable header and dial gauge that allows for constant mixer adjustability. While in operation, the rotational shearing (mixing) is controlled by adjusting the distance between the end of the rotor and the inside header. This unique feature, not found in other extruders, allows for various extrudate mix levels in a single sample run. The rotational shearing of the LME system provides extensive and intensive mixing and can be used in the production of polymer blends or alloys. These blends have been found homogeneous enough to be spun into fibers over the entire range of composition. Since mixing may be independently adjusted, agglomerates of additives, such as fillers or pigments, may be accurately controlled.
Features:
- Maximum temperature 400°C
- Variable speed control, 5-260 rpm
- Standard rod header
- Replaceable .3175 cm (1/8 in) orifice
- Water-cooled feed hopper
 Model LMM Laboratory Mixing Molder
The versatile Laboratory Mixing Molder is designed to mold miniature specimens for dynamic, tensile and impact testing. This benchtop mixer, extruder and molding machine will produce cost effective moldings using less than one gram of material. This compact R & D tool allows production of cost effective moldings for testing standard or newly
developed thermoplastic material.
The LMM prepares a polymer melt for injection using two types of mixing: extensive and intensive. This combination ensures material homogeneity for the feed process. Intensive mixing produces high shear rates to break up clumps of material. Extensive mixing causes a folding type of material action to uniformly distribute the various ingredients of the melt. Mixing begins when the sample materials are heated through the conduction and mechanical shearing of the rotor. From mixing to a finished mold, the LMM is capable of cycle times less than 30 seconds.
Features:
- Molds miniature specimen for dynamic, tensile and impact
- Effective moldings from less than 1 gram of material
- Interchangeable cup capacities
- Sample cycles in less than 30 seconds
- Digital display PID temperature controller
- Operating temperature from ambient to 400°C
- Standard C-clamp to secure molds
