99% Alumina Ceramic vortex generator tube sleeve
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Points of the grouting operation process (1) When grouting, the mud on the model should be wiped out, and the feeding speed should not be too fast, so that the air in the model is discharged with the injection of the mud, to prevent air from mixing into the mud, and Defects on the surface of the green body. (2) When pouring large products, in the parts with large shrinkage such as edges and corners, before the grouting, you can put silk cloth on the corresponding place in the model to make the speed of moisture movement of each part as balanced as possible to prevent Cracking. (3) For products that need to be formed on the core, sprinkle powder on the core in advance to help mold release. (4) Master the length of the pulp time to ensure the thickness of the green body. Open your eyes, and the speed should not be too fast, so as to avoid negative pressure in the model, which will cause the body to leave the model prematurely and cause deformation or collapse. (6) When repairing, the component body should have a slightly lower moisture content than the main body 2 % ~ 3%. Manufacturing process of ceramic grouting molds 1 Manufacturing process of molds The production of sanitary ceramic molds is a complex and meticulous work that requires high skills. A series of rigorous work. The general manufacturing process can be divided into the following five steps: Step 1: Prototype Inch consistent with the sanitary ceramics products. System is made based on the design drawings (or sample). Ruoyi have physical samples need to be generic, the first step may be omitted.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
