注浆成形的生产过程由以上9道工序组成,其中：
吃浆就是模具吸附泥浆中的水分,形成坯体的工序.
放浆又称空浆,是当坯体形成一定厚度时,排出多余泥浆的过程.放出的泥浆返回浆池(或罐).回浆的方式有：(1)人工端桶回浆：(2)自然压力回浆,利用管道的坡度,使泥浆流回泥浆池；(3)利用泥浆泵抽回余浆：(4)负压回浆,即利用下注式压力注浆管道,用真空泵形成的负压,把泥浆抽回到泥浆罐.在以上各种方式中,除第一种外,均属于管道回浆.
巩固：放浆后坯体很软,不能立即脱模需经过一段时间继续排出坯体水分,增加其强度.这段时间称为巩固.巩固是注浆成形的主要工序之一,其持续时间约为吃浆时间的一半.
在巩固过程中由于模型继续吸水,坯体含水率不断下降,坯体由于水分排山而逐渐收缩.当坯体含水率下降到19-20％左右时(即脱模点),巩固过程结束,此时坯体很容易从模型内取山.
脱模：从模型中取出粗坯的过程.脱模点的掌握是一个关键.脱模过早,坯休强度不够,脱模困难,且脱模后坯体易塌陷；脱模过迟,坯体会发生开裂.
修粘：包括一次修坯、打眼与粘接等过程.传统的注浆方式,脱模后的坯体内外表面都很粗糙.一般需经多次修坯,而且粘接的工作量也很大.现代采用高强石膏模或树脂模,压力注浆等手段,修粘的工作量已大为减少.修坯、打眼与粘接这些工作都需手工进行,容易出现废品,必须掌握好坯体含水率.
干燥：预干燥(也称半干),即将坯体含水率从15％～17％(粘接时的含水率)降低到8％左右.
传统浇注方式,坯体的预干燥是在注浆车间内进行自然干燥的.在工人下班后的16小时内,注浆车间内保持高温度(33～40℃)、高湿度(40％一60％),使坯体缓慢的干燥.经预干燥后,湿坯休的含水率从15％～17％下降到8％一10％.要注意防止因干燥过急或干燥不均匀,而造成废品.
现代注浆方式一般采用热风直接对坯休进行强制干燥,玻化瓷坯体预干燥收缩率为4％,粘土坯体预干燥收缩率为2％.
二次修坯(修刷)：是注浆成形的最后一道工序,将最终决定坯体的尺寸.修刷时坯体含水量要少、刷坯用水也要少,不能有油污.坯体修刷完毕后存放在28-35℃的室内,准备进行施釉.
2 注浆操作过程要点
(1)注浆时,要擦掉模型上的泥缕,进浆速度不宜太快,以使模型中的空气随泥浆的注入而排出,避免空气混入泥浆中,以及避免使坯体表面产生缺陷.
(2)浇注大型产品时,在棱角等收缩大的部位,注浆前,可在模型内的相应处贴上绸布,使各部分水分移动的速度尽量均衡,以防止开裂.
(3)需上型芯成形的制品,事先在型芯上撒石粉,
(4)掌握好吃浆时间的长短,以保证坯体的厚度.
(5)放浆前应敞开气眼,速度不宜太快,以免模型内产生负压,使坯体过早脱离模型造成变形或塌落.
(6)修粘时,零部件坯体应比主坯体含水率稍低2％～3％.

Casting production process by above 9 component processes, in which:
The grout is the mold of mud in the moisture adsorption, form body process.
The slurry discharge is also called air plasma, is when the body to form a certain thickness, removing excess slurry process. Release of the mud return slurry pool ( or tank ). Back to the slurry in the way: ( 1) manual end of the barrel back pulp: (2 ) the natural pressure back to the slurry, using pipeline slope, the mud flow back into the mud pool; ( 3) using a mud pump back to the residual pulp: (4 ) negative pressure slurry return, namely the use of bet type pressure grouting pipe, vacuum forming the negative pressure, the mud is pumped back to the mud tank. In the above manner, except the first one, belong to the pipeline slurry return.
Consolidate: put the paste body is soft, not immediately release required after a period of time to discharge body moisture, increase its strength. This period of time known as consolidation. Consolidation grouting forming is one of the main processes, its duration is approximately half the time to eat the pulp.
In the consolidation process due to water absorption model, body water content decreases, body gradually shrink due to water at. When the body water content decreased to about 19-20% ( i.e. release point ), to consolidate the process ends, the body easily from within a model of mountain.
Release : the rough blank is removed from the mold process. The master node is a key. Release early, blank had strength enough, demoulding difficulty, and after demoulding demoulding body easy collapse; later, billet of cracking.
Repair stick: including a trimming, punching and bonding process. The traditional ways of grouting, after stripping the body inside and outside surfaces are rough. Generally required repeatedly trimming, and bonding the workload is very big also. The modern use of high-strength gypsum mold or mold, pressure grouting and other means, fix the sticky workload has been greatly reduced. Trimming, punching and binding the work is performed manually, prone to reject, must master the body water content.
Drying: drying ( also known as semi dry ), the body water content from 15% to 17% ( when bonding the moisture content is reduced to 8% or so ).
Traditional casting, billet pre drying is in casting shop within the natural drying. The workers work 16 hours after grouting, plant to maintain high temperature ( 33 ~ 40 ), high humidity (40% - 60% ), make the body slow drying. Pre dry, wet blank off moisture from 15% ~ 17% drops to 8% 10%. Attention should be paid to prevent drying or drying too uneven, resulting in waste.
Modern grouting way adopts hot air directly on a blank Hugh forced drying, vitrified porcelain body pre drying shrinkage ratio of 4%, the clay body pre drying shrinkage ratio of 2%.
The two base repair ( repair brush ): is the casting in the final process, will ultimately determine the blank size. Repair brush body, brush less moisture to green water is less, not greasy. Body repair brush after stored in 28-35 C indoor, ready for glaze.
2 key points of grouting process
( 1) injection, to erase the model mud on the strand, a pulp inlet speed should not be too fast, so that the model in the air with the slurry injection and discharge, avoid air mixed with mud, and to avoid the body surface defects.
( 2) pouring large products, such as in the edges of contraction of the site, grouting, in the model the corresponding attaching the silk, make each part of water moving speed balanced as possible, in order to prevent cracking.
( 3) to be core molding products, advance on the core and powder, help release.
( 4) master the delicious pulp of the length of time, in order to ensure the thickness of bodies.
( 5) the slurry discharge should be open air, speed should not be too fast, so as to avoid the negative pressure is generated in the model, so that the body of premature detachment model causing deformation or collapse.
( 6) fix the sticky, parts of body should be higher than the main body water content lower 2% ~ 3%.
