Processing Procedure The standard procedure of processing TAITACELL® EPS Resin beads into expanded blocks or molded articles include three stages: Prefoaming, Conditioning and Molding.
  1. Prefoaming:
    The beads are heated by hot water, hot air, steam or infrared heating in a batch or continuous operation. The beads are, thus expanded to about 50~90 times their original volume and the density is reduced to as little as 15Kg/m3. Bulk density of prefoamed beads varies with the equipment, temperature and time. Therefore a trial run is necessary to determine the optimum operation conditions. The final density of the finished blocks or moldings will be the same as the bulk density of prefoamed beads.
  2. Conditioning:
    The prefoamed beads are conditioned at room temperature in a ventilated area which allows beads to dry and aerate. The conditioning generally requires 24 hours and is essential to the quality of the molded products. However, when using fast molding EPS, the condition time should not exceed 16 hours.
  3. Molding:
    A perforated mold is filled with conditioned perfoamed beads and low pressure steam is admitted through the small holes of the mold. This steam sweeps away the air in the interstices between beads. After a short time the steam pressure is increased to about 0.5~1.0kg/cm2 causing the perfoamed beads to fuse in the mold. The mold is then water or air cooled to allow the removal of the molded article.
