Gear pump Cold feed Rubber Preformer machine
Gear pump Cold-feed Precision Rubber Preformer is an efficient and high-precision rubber blank production equipment, which cuts the mixed rubber into the desired shape and weight, with a weight accuracy of less than ±1%. The cold (normal temperature) rubber strip is directly fed continuously , pre-warming by the open roller mill is not required any more,facilitating the operation procedures and tremendously improving the production capacity.
The cold feed rubber preformer machine has strong adaptability and is suitable for various rubber materials such as NBR, EPDM, FKM,etc. It can extrude various circular, rectangular, strip, and irregular rubber blanks. It is suitable for producing rubber products such as seals, oil seals, valve stem, bottle stoppers, tennis balls, golf balls, shoe soles, etc. Covering various functions such as filtering, extrusion, cutting, weighing, counting, etc. The Continuous Cold feed Gear-pump powered rubber preformer is replacing the normal hot-feed preformer,becoming more and more popular among the rubber parts manufacturers.
