1、Batching and ball milling. Most mug manufacturers are using the factory ready-made ceramic blank formula, to facilitate unified management. Poor with fine ceramic billet formula, the general use of general porcelain formula, good point with bone china formula. Determine the formula, all raw materials into the ball mill, add water, grinding aid to start ball milling, about 15-30 hours after the ball, sieve, remove iron. 2、Before molding raw material treatment mug according to the post-process molding method, there are two kinds of raw material treatment: injection molding method, raw materials to adjust the specific gravity, add water glass and other additives can be used for molding. For spinning method, the raw material should be filtered out the excess water on the filter press, and then refined into the required mud section by the mud making machine, and then it can be used for molding after aging. 3、Molding Pulping method: according to the design of the shape of the mug turned out hundreds of sets of plaster molds, dry state in turn injected into the slurry, to be plaster mold to absorb the water in the slurry to form a certain wall thickness, pour out the excess slurry, control the mold, demold, dry, repair the blank, the formation of billet waiting to be loaded kiln. The disadvantage of this method is that the production efficiency is low, all rely on manual labor, need a large place, and not suitable for management. However, the advantage is that it can be formed once, without the need for secondary bonding, and forming is not bound by the geometry of the shape, can be formed any difficult shape. Spinning method of molding: the use of daily-use porcelain factories ready-made dish spinning molding machine, the fixed amount and shape of the clay into the special spinning mold, demolded into a mug body part, but the cup handle to be made separately and in the drying of the bonding. This method has the advantage of high production efficiency and is suitable for mass production. The disadvantage is that there are restrictions on the shape, special shape can not be completed. 4、Load kiln Su firing traditional process after drying and repairing the billet to the kiln at 1200-1300 ℃ high temperature firing, called Su firing, giving the strength of the billet, ready for glazing. There are also a few factories do not hang glaze firing directly by plain firing, but the process is not very good control. 5, glaze glaze process more, there are dipping glaze, brush glaze, swing glaze, spray glaze, etc., with equipment from special scribing machine (two-color cup with), spray glaze machine, to the gun, air compressor vary. But glaze or human-centered, the operator's experience and proficiency is most important. 6、Glaze firing The products with good glaze should be fired into the kiln for the second time by high temperature of 1000-1200℃, called "glaze firing". 7, on the "mark", high temperature stereotypes No matter how complex the "mark", they can be reduced to a "glaze", is a low-temperature decorative effect glaze, can be designed in advance Design and production of decal paper, stick to the cup can be, can also be screen printing process printed on the cup, of course, can also be hand-painted, spray painting. After the "mark" to send the product to the baking kiln by 500-800 ℃ will be fixed to the cup body glaze layer. So far a complete mug is complete.
