## Abstract

A multi-surface appliquing method is provided for a melamine container. The method is process for producing a melamine container that has inner and outer appliques performed with a single mold in a single processing machine. A single mold used in a single processing machine is used to mold a blank formed of a material and the blank provides an adhesion force before being completely cured. The adhesion force is used, together with glitter powders (resin based glitter powders of melamine) adjusted for a different curing time, in such a way that the properties of the two materials, together with producing condition realized through adjusting a hydraulically operated processing machine, allow for production of a melamine container having inner and outer surfaces of applique with a single set of mold.

## Claims

### Claim 1

A multi-surface appliquing method for melamine container, comprises the following steps:
(a) depositing a material in a mold composed of a male molding member and a female molding member;
(b) heating the material for molding with the male and female molding members being controlled at a predetermined range of temperature difference, whereby after the mold is open, the material for inner appliquing is not completely cured and thus possesses an adhesion force;
(c) with the material, after the mold being opened, sticking to the male molding member, positioning a predetermined applique layer in the female molding members for performance of appliquing operation; and
(d) opening the mold again after completion of the appliquing operation and applying glitter powders to an appliqued pattern sheet and closing the mold to complete appliquing outside the product.

### Claim 2 (depends on 1)

The method according to claim 1 further comprising the following step: (e) controlling curing time of the glitter powders so that an appliqued surface is attached, with an adhesion force provided by the glitter powders that are not cured, to the mold to carry out appliquing on another surface.

### Claim 3 (depends on 1)

The method according to claim 1, wherein in step (b), heating is performed by using a hydraulically operated processing machine to control temperature in such a way that the male molding member has a temperature that is higher than a temperature of the female molding member.

### Claim 4 (depends on 1)

The method according to claim 1, wherein in step (b), the predetermined range of temperature difference is ±17° C.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the material is selectively changed for color or property.

### Claim 6 (depends on 1)

The method according to claim 1, wherein in step (d), the glitter powders are cured with a doubled curing time.

### Claim 7 (depends on 1)

The method according to claim 1, wherein the female molding member forms a recess.
