The present invention relates to a method and device for manufacturing artificial marble. According to the present invention, artificial marble having a stripe pattern similar to that of natural stone, such as striato, may be provided.

The present invention relates to a thermoplastic resin substrate for a curved mirror and a method for preparing the same, and a curved mirror and a head-up display comprising the thermoplastic resin substrate. The preparation method comprises the following steps: A) heating up a mold of an injection molding machine to a temperature in a range of 130-190° C. and closing the mold, B) injecting a molten thermoplastic resin into the cavity of the mold cavity, C) applying a pressure of 300-700 bar to the cavity for a period of 5 or more seconds, D) stopping applying pressure and cooling the mold to a temperature in a range of 60-100° C. within 10-50 seconds, and E) opening the mold and taking out the molded thermoplastic resin substrate, wherein a gap of 0.3-1 mm is left between the parting surfaces of the cavity of the mold prior to applying the pressure to the cavity. The thermoplastic resin substrate according to the present invention features a large size, high dimensional stability, and low surface roughness. It can be used for future augmented reality head-up displays to realize large-area, long-distance projection and high-precision imaging, thereby satisfying the requirements for driving safety and comfort of future automobiles.

This document describes systems and processes for forming synthetic molded slabs, which may be suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

The present invention relates to a method and device for manufacturing artificial marble. According to the present invention, artificial marble having a stripe pattern similar to that of natural stone, such as striato, may be provided.

A method of fabricating a three-dimensional object, the method comprising (a) providing a polymer microfiller composite comprising a molecularly self-assembling (MSA) material and a microfiller dispersed in the MSA material; (b) depositing the polymer microfiller composite; and (c) repeating the depositing step until the three-dimensional object is formed.

In a golf ball having a core and a cover, the core is formed of a rubber composition, has center and surface portions which are unfoamed regions and has an intermediate portion containing a foamed region. The core is produced by charging the rubber composition, which contains a blowing agent, into a first curing mold and curing under given conditions, then removing the molded rubber material in a semi-cured state from the first mold, transferring the semi-cured material to a second curing mold and curing under given conditions. The foamed region of the core deforms by a certain degree at the time of impact, decreasing the radius of gyration of the ball and enabling a lower spin rate to be achieved. The decrease in resilience due to expansion of the molded material can be held to a minimum.

The disclosure relates to a process for manufacturing a building panel, such as a floor panel, including a core. The process includes providing a core material including a thermoplastic material, a filler and hollow microparticles, and applying heat and pressure to the core material to form the core. The disclosure also relates to a corresponding building panel.

An exemplary embodiment of the present disclosure provides a fire resistant material and methods of making same, the fire resistant material comprising a material incorporating a mixture comprising carbon nanotubes, nanoclay, and a dispersing agent.
