Ceramics manufacturing process at Armatura Group

each new product of bathroom sanitary ceramics is developed in the design studio on the basis of drafts and preliminary designs the designer develops a network model using an application for three-dimensional modeling and prepares technical documentation covering structural data and process parameters a working mold made of plaster is built in the pattern shop according to these guidelines to achieve this the master mold is filled with plaster and left clamped with metal clamps for approximately 20 minutes as this is enough time for the plaster to set the casting is cleaned and clamped off to complete assembly and put in a drying room for around two weeks individual materials needed to make the casting slip are taken from the raw material store and undergo microscopic assessment they are then examined in the laboratory after weighing which is carried out according to a specific formula the raw materials are fed into four mills for 12 to 18 hours the decision to stop milling is made by the laboratory after an examination of the weight viscosity and civil rescue of the casting slip the casting slip then goes to the foundry the casting process is carried out mechanically on benches with working molds as soon as a shell of the required thickness is obtained surplice casting slip is blown off using compressed air after approximately one and a half hours the clamp is released and the castings are removed from the molds then the semi finished products undergo a working process and are labeled finally they go to racks where they dry for five days this is followed by quality acceptance and then castings are sent to the glazing workshop dust is removed from the semi finished products using compressed air at a maximum pressure of four at before being washed with warm water glaze spraying is carried out in cubicles using spray guns during the glazing process which usually lasts 60 seconds the casting is evenly coated with an approximately 1 millimeter thick glaze layer drips are removed from glazed semi-finished products which are then transported to the furnace room here after around 8 hours of drying they go to the tunnel furnace where they are fired at a temperature of 1230 degrees Celsius the furnace operates in a continuous mode the average cycle lasting for 30 hours the finished product goes to the sorting plant where it undergoes other quality checks and products showing no defects are sent on for packaging after careful packaging the product is placed on pallets and wrapped in foil you you
