1) A wide range of adaptation. The casting method is almost independent of the size, thickness and shape of the casting. The wall thickness of the casting can reach 0.3 ~ 1000mm, the length ranges from a few millimeters to more than ten meters, and the quality ranges from a few grams to more than 300t. It is most suitable for the production of complex shapes, especially for complex internal parts, such as complex cabinets, valve bodies, impellers, engine blocks, propellers, etc. 2) The casting method can be used in a wide range of materials, and almost all alloy materials that can be melted into a liquid can be used for casting. Such as cast steel, cast iron fly various aluminum alloys, copper alloys, continuous alloys, iron alloys and tantalum alloy castings. For brittle alloy materials with poor plasticity (such as ordinary cast iron, etc.), casting is the only feasible forming process. In industrial production, cast iron parts are the most widely used, accounting for more than 70% of the total output of castings.
We use patented technology to penetrate and stick directly.
The surface of the board is directly laminated with melamine paper, without any interlayer in the middle, which improves the fire resistance level. It has no formaldehyde, no phenolic glue, high bonding strength, and good fire resistance. , Is a national A-level (national standard) fireproof board, the flame lasts for zero burning time, 800 ℃ does not burn, 1200 ℃ no flame, in line with the national A-level fire protection standards, the fire resistance limit reaches more than 4 hours, can be absorbed in the process of burning A large amount of heat energy prevents the fire from spreading and delays the increase of the surrounding temperature.
Our Melamine surface decorative magnesium oxide board can be boiled for 4 hours without the layers unfloding. In dry, cold and sloping weather, the performance is always stable, unaffected by condensed water droplets and vertical air, even if it is soaked in water for several days, it can be used normally after being recovered from naturally dried. It will not be deformed and affect the strength,and there're no No water droplets,no condensation phenomenons.

3) Castings have a certain dimensional accuracy. In general, it is more accurate than ordinary forgings and welded parts.
4) Low cost, comprehensive economic performance, energy, material consumption and cost are not as good as other metal forming methods. Castings account for 40% to 80% of the total mass in general machines, while manufacturing costs only account for 25% to 30% of the total machine cost. The reasons for the low cost are: 1 Flexible production mode, mass production can organize mechanized production. 2 can make extensive use of waste, old metal materials and renewable resources. 3 Compared with forging, its power consumption is small. 4 has a certain dimensional accuracy, so that the machining allowance is small, saving processing time and metal materials. Casting is a major supplier of blanks and parts for the mechanical manufacturing industry and plays an extremely important role in the national economy. Castings account for a large proportion of mechanical products. For example, key parts of internal combustion engines (eighty-nine kinds) are castings, accounting for 70% to 90% of the total mass, and the quality of castings in automobiles accounts for 19% (cars) ~ 23% (trucks); The quality of castings in machine tools, tractors, hydraulic pumps, valves and general machinery accounts for 65% ~ 80%; castings in agricultural machinery. 40% ~ 70% of the quality of mining and metallurgy (steel, iron, non-ferrous alloys), energy (fire, water, nuclear power, etc.), marine and aerospace industries, heavy, large, difficult equipment, castings account for a large proportion Play an important role.
