 Alumina ceramic abrasion resistant lining as wear-resistant materials with high performance is widely used in various industries, then how is it formed?  Pingxiang chemshun ceramics co.ltd is professional alumina ceramic abrasion resistant lining manufacturer,chemshun ceramics company is to be a formerunner in the field of wear resistant ceramics .  now we are pleausre to show your the tips of alumina ceramic molding method 

 

1, Alumina ceramic abrasion resistant lining dry pressing: this technology is limited for simple shapes and the inner wall thickness of more than 1mm, length to diameter ratio of not greater than 4 items. Molding methods uniaxial or bidirectional. Pressing machines has hydraulic, mechanical , semi-automatic or fully automatic molding methods. The maximum pressure of the press 200Mpa. Production of up to 15 to 50 per minute. Since the hydraulic press stroke pressure evenly, so there are differences at the time of filling the powder pressing member of different heights. The size of mechanical presses pressure change due to the number of powder filling, easily lead to shrinkage after sintering dimensions differences affect product quality. Thus the process of dry-pressed powder particles uniformly distributed on the mold filling is very important. Filling volume is accurate or not for the manufacture of ceramic parts dimensional accuracy control of a significant impact. Powder particles greater than 60μm, between 60 ~ 200 mesh will receive the maximum free flow effects, pressure forming to obtain the best results.


 2, alumina ceramic abrasion resistant lining slip casting method: wear-resistant ceramic slip casting is formed using the first method. As a result of the cast, low cost and easy to shape large size, shape complex parts. CASTING key is preparation of a slurry. Usually water flux medium, then add glue and binder solution, fully milled exhaust after, then pour injected into the plaster mold. Since the plaster mold capillary adsorption of water, slurry then curing the mold. Hollow grouting, die wall during adsorption slurry of desired thickness, the need to pour out the excess slurry. To reduce the amount of green body shrinkage, should make full use of high concentration slurry.
