Glass bottles and glass products casting and molding process! ! !

The principle of the casting process

The glass is melted and molded by a die. Generally, after the mold is manufactured, the glass melt is injected into the mold or the glass scrap is stacked in a mold prepared in advance. The mold is put into a melting furnace and melted, and the glass mold is annealed after being anastomized.

1. Lost wax casting method (1), using the mud to make the original mold (2), overturning the silicon rubber negative mold and fixing it with plaster (3), pouring the wax liquid into the silicone rubber mold, casting a waxy " Prototype, called "wax model"
(4) After cooling, remove the wax type, carry out finishing (5), a fire-retardant embedding wax type (6), heating and dewaxing, and form a prototype-shaped cavity (7) in the high-temperature resistant material. The glass block is filled into the mold and placed in the furnace for heating. The glass block gradually melts and fuses until it completely fills the cavity and can be annealed (8).

2, blown glass manufacturing process steps

(1) Picking material: firstly put one end of an iron pipe with a length of about 1200-1500 mm or one end of a stainless steel pipe into an oven and heat it to a suitable temperature so as to stick to the glass liquid. Gradually, the molten glass in the crucible is picked up. (2) Blowing: The material to be picked up is rolled into a glass mass in a rolling board or a rolling bowl, and blown into the softened glass from one end of the blowing rod on a special manufacturing table to make it Become a hollow, thick-walled blister, and then either blow it into a material bubble, or use the fluidity of the glass itself to form a material bubble (3), shaping: keeping the material bubble continuously under constant rotation and air blowing. Swelling, operation using only pliers, scissors, tweezers, splints and templates and other special hand-tool molding or trimming with scissors (4), finishing: After the product is annealed, cutting, baking and other processing and finishing

3: Lamp processing technology

Tools used: torches, anvils, tweezers, needles, scissors, pliers

The process used: squeeze, pull, forceps, glue, shear, twist, bend

step:
(1) First soften (2) with torch material, (3) with tools, (3) with tools, and always pay attention to the relationship with the overall image in local production, and constantly adjust until the completion (4), adjust the work on the anvil The work of the center of gravity (5) and lamp craftsmanship must be completed after annealing.

4: Groove sinking process

step:
(1) The glass or plate glass is cut into a certain shape according to the mold. In particular, the flat glass covered on the deep mold, which is to take into account the change caused by the softening and bending of the glass, leaving more room (2), placing the raw material on the supporting edge of the grinding tool (3), and feeding it into the heating furnace. Uniform heating, if the bending of the product is relatively large, the mold is deep and can be divided into two parts. (4) The baking and heating time is related to the size and thickness of the product. (5) Annealing

5: Flower craft

step:
(1) Arrange the glass rods of different thicknesses in different colors into a group, cut them into sheets (2), and then heat them to make them blend into one. (3) Combine these thin sheets to form a so-called “flower”
(4) A piece of flower is affixed or inlaid on the surface of the glassware (5) to form a "flower" glass product

6: Pressing process

step:
(1) Pick up the glass frit, cut a certain amount into the mold (2), put down the mold ring (3), drop the core (4), and fill the space (5) between the inner and outer molds with the soft glass. After the glassware has cooled slightly, it is removed and annealed and finally polished.

There are also some other techniques. Such as: heap flower process, drop coagulation method, entangled diarrhoea method, sibling method, laying silk method.

These are some very simple process methods that can only produce relatively simple glass products. In our production process, we use a combination of various processes to create our own glass.
