Kind Code:
A
Abstract:
The present invention relates to an apparatus for manufacturing foamed thermoplastic resin pellets and method thereof. The manufacturing apparatus includes a cylindrical dice, a plurality of extrusion holes formed along a radial direction of the dice and communicated with a resin flow path formed at the dice, a guide symmetric with the extrusion holes and protrudingly formed at the whole or a portion of outer circumference surface along the longitudinal direction of the dice, an operation member slidably installed along the guide, and a cutting knife with penetration holes being formed along the longitudinal direction of the knife and being communicated with the extrusion holes, wherein both ends of the knife are fixed at the upper edge of the facing planes of the operation member, and its center in the traverse direction is downwardly curved such that it is contacted with the contact line of the extrusion holes. A foaming-rate regulating member is installed at the outer circumference surface of the dice.
