WAYNE, N.J. - ALM Corp. spent $1 million to build a new twin-screw extruder that will boost its capacity of custom compounded and specialty alloyed engineering resins. The extruder adds about 4 million pounds of capacity for nylon, polybutylene terephthalate, polycarbonate and poly-phenylene ether, said Jack Ryan, ALM vice president of sales.
``As a compounder we need fast inventories,'' Ryan said.
The company also does large-batch homogenizing and testing at its 500,000-square-foot plant in Wayne, which houses four twin-screw and six single-screw extruders, he said. Total annual capacity for custom compounds is about 30 million pounds.
ALM designed the extruder, which features four entry points for additives, allowing heat-sensitive and reactive agents to be added later in the compounding process to preserve their mechanical properties, he said.
``For example, the later lubricant is added in the process, the better the resin retains its lubricity and post-mold release effect,'' Ryan said.
ALM's sister company, Cus-tom Resins Inc., produces nylon resins in Henderson, Ky. The Parent company, Polymeric Resources Corp., is based in Wayne.
