Reputation depends on quality,  quality comes from Hard!

Alumina Ceramics:

1. Good overall technical alumina ceramic performance, high impact strength, chemical stability, and good electrical properties;
2. It has good weldability with 372 plexiglass, made into two-color plastic parts, and can be chrome-plated and painted;
3. There are high impact resistance, high heat resistance, flame retardant, reinforced, transparent and other levels;
4. The fluidity is slightly worse than HIPS, better than PMMA, PC, etc., and flexibility is good;
5. Suitable for making general mechanical parts, wear-reducing and wear-resistant parts, transmission parts and telecommunication parts.
(2) Forming performance
1. Amorphous material, medium fluidity, high moisture absorption, and must be fully dried. Plastic parts that require gloss on the surface must be preheated and dried for a long time at 80-90 degrees for 3 hours;
2. It is advisable to take high material temperature and high mold temperature, but it is easy to decompose if the material temperature is too high (the decomposition temperature is >270℃). For plastic parts with higher precision, the mold temperature should be 50-60℃; for high-gloss and heat-resistant plastic parts, the mold technical alumina ceramic temperature should be 60-80℃;
3. If you need to solve the water trapping, you need to improve the fluidity of the material, adopt high material temperature, high mold temperature, or change the water level, etc.;
4. If heat-resistant or flame-retardant materials are formed, plastic decomposition products will remain on the surface of the mold after 3-7 days of production, which will cause the surface of the mold to shine, and the mold must be cleaned in time, and the surface of the mold must be vented;
5. The cooling rate is fast. The mold gating system should be thick and short. The cold material cavity should be set, and the gate should be large, such as direct gate, disc gate or fan gate, etc., but internal stress should be prevented If necessary, an adjustable gate can be used. The mold should be heated and wear-resistant steel should be used;
6. The material temperature has a great influence on the quality of plastic parts. If the material temperature is too low, it will cause lack of material, the surface is dull, and the silver wire is disordered.
7. The mold temperature has a great influence on the quality of plastic parts. When the mold temperature is low, the shrinkage, elongation, impact resistance, bending resistance, compression resistance, and tensile strength are low. When the mold temperature exceeds 120℃, the plastic parts will cool slowly, easily deform and stick to the mold, difficult to demold, and the molding cycle is long;
8. The molding shrinkage rate is small, melting cracking technical alumina ceramic is easy to occur, and stress concentration occurs. Therefore, the molding conditions should be strictly controlled during molding, and the plastic parts should be annealed after molding;
9. The melting temperature is high, the viscosity is high, and it is not sensitive to shearing. For plastic parts larger than 200 grams, screw injection machine should be used. The nozzle should be heated. It is appropriate to use an open extension nozzle. The injection speed is medium and high.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
