Abstract
The present invention provides an apparatus and method for manufacturing super high fluidity urethane-based spherical fine powder for powder slush molding by melting and mixing a super high fluidity urethane-based thermoplastic resin at high temperature, passing the thermoplastic resin through micro-sized fine holes to be extruded into a fine diameter, cutting the extruded thermoplastic resin into spherical fine powder having a uniform particle size, and drying the cut spherical fine powder.
Description
technical field [0001] The invention relates to a device and a method for manufacturing ultra-high fluidity urethane-based spherical fine powder. More particularly, the present invention relates to an apparatus and method for producing spherical fine powder for powder slush molding by melting and mixing an ultra-high fluidity urethane-based thermoplastic resin at high temperature, making the thermoplastic resin Extruding to a fine diameter through micron-sized pores, cutting the extruded thermoplastic resin into a spherical fine powder having a uniform particle size, and drying the cut spherical fine powder. Background technique [0002] The instrument panel of a vehicle is a decoration pad that preferably includes mounting areas for the instrument panel, air back, glove box, and the like. For example, in luxury vehicles, the surface material of the dashboard is often formed by powder slush molding to provide a sense of luxury. [0003] That is, the dashboard surface mater...
