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.
