Method and device for manufacturing artificial stone

摘要

The present invention relates to a method and device for manufacturing artificial stone. More specifically, the method includes the steps of: (a) mixing two or more kinds of chips having different grain sizes with a raw material for artificial stone; (b) injecting the raw material for artificial stone mixed with the chips into a mold; (c) applying primary vibration using a vibration device such that the raw material is uniformly dispersed in the mold; (d) applying vacuum to eliminate bubbles in the raw material; and (e) molding artificial stone by applying a secondary vibration using the vibration device. According to the method and device for manufacturing artificial stone of the present invention, the deposition rate of chips exposed at a surface of artificial stone is maximized, and thus the external appearance of artificial stone can be more naturally expressed and resistance against abrasion and staining can be improved.

1. A method for manufacturing artificial stone, comprising:
(a) mixing two or more kinds of chips having different grain sizes with a raw material for artificial stone; (b) injecting the raw material mixed with the chips into a mold; (c) applying primary vibration to the mold using a vibrator at a normal pressure to uniformly disperse the raw material in the mould between 10 seconds and 1 minute; (d) evacuating air around the mold to create a vacuum around the mold in order to remove bubbles from the raw material; and (e) applying secondary vibration to the mold using a second vibrator at a normal pressure to mold artificial stone between 30 seconds and 5 minutes.
