production process: material opening, pressing, coarse polishing, fine polishing, drilling, carving, sandblasting, viscose, quality inspection, packaging
Two, the crystal product classification: engraved, plane, engraved and plane and hand-carved four kinds.
Iii. Processing process description:
1, cutting: the whole material with a high speed saw blade saw out of the shape and size required by the blank.
2. Pressing: make the required size and shape of the finished product with the mold, and then melt the raw material at a high temperature above 900 ℃, flow into the mold and die cast it.
3. Rough polishing: it is to press the rough embryo out of the mold and grind the engraved line of the finished product directly with the diamond disc.
4, fine polishing: after coarse polishing, polishing powder to grind the finished product until crystal clear.
5, drilling: is not finished before the crystal products, according to the required size and location of drilling, to drill, such as table, pen container, bottle hole, etc.
6, silk-screen printing: crystal surface with different color materials for effect treatment, color layer is thick, focus can fall off.
7, plating color: similar to the use of electroplating techniques in crystal surface with different colors, the layer is relatively thin, can be scratched by friction, scratch, because plating color is often located at the bottom, so the bottom of the plating color often use other objects attached, such as sheng xiaowen town.
8, sculpture: three-dimensional sense, high technology, fine work, high cost.Divide hand carve graph, machine carve character.
9, sandblasting: three-dimensional sense is weak, relatively flat, no concave and convex feeling, machine carving text, graphics, etc. After effect processing.Low cost and fast production.
10. Laser engraving: it adopts computer-assisted laser equipment to form three-dimensional patterns in crystal objects. With good artistic effect, it can express all kinds of patterns and patterns at will to achieve realistic effects
