Abstract
An extrusion molding apparatus for forming a product having an extrusion molding. The extrusion molding apparatus includes an extruder extruding the product through a die installed at an outlet of the extruder. A second inlet is formed at one side of the die to receive a second synthetic resin. A second extruder feeds the second synthetic resin into the second inlet and a passage in fluid communication with the second inlet. The passage transports the second synthetic resin to nozzle grooves formed in the die, thereby coating the second synthetic resin on a surface of the product extruded from the die having a first synthetic resin.
Claims19
An extrusion molding apparatus, comprising:
- an extruder extruding product formed from thermoplastic synthetic resin through a die, which is installed at an outlet of the extruder, the die having a first portion with a groove and a second portion with a corresponding groove to form a passageway, a second inlet being formed at one side of the die in communication with the passageway to feed a second synthetic resin from a second extruder through the second inlet, wherein the passageway communicates with an original synthetic resin passage formed in the die such that the second synthetic resin coats a surface of the product extruded from the die.
An extrusion molding die, comprising:
- a die installed at an outlet of an extruder including;
- a synthetic resin passage provided at one side of the die to receive synthetic resin from the extruder;
- a second inlet formed at another side of the die to feed a second synthetic resin thereto,
- a second passage in communication with the synthetic resin passage and with the second inlet to coat the second synthetic resin on a surface of a product extruded from the die;
- and
- a plurality of nozzle grooves in communication with the second passage so that the second synthetic resin of a predetermined ratio covers a surface of the product.
An extrusion molding apparatus, comprising:
- a die;
- a first extruder connected to a portion of the die;
- a second extruder connected to another portion of the die;
- a first synthetic resin passage formed through the die;
- an inlet passage formed in a portion of the die for receiving a second synthetic resin from the second extruder;
- a retainer groove in fluid communication with the inlet passage and formed in a portion of the die;
- and
- a plurality of nozzle grooves in fluid communication with the retainer groove and the first synthetic resin passage,
- wherein the first synthetic resin passage is arranged in an inner circumference portion of the retainer groove.
