Compressors & Gears
Rayforce's metal die casting gears can be applied to Turbo blowers, air control components, piston compressors, casting gears, etc.
Application of Die Casting Gears in Air Compressors
With the continuous development of the automotive industry, the efficient high-precision die casting gears production process including squeeze die casting is widely used in the production of automotive parts. Among them, the air conditioning compressor shell is a class of commonly used casting gears. This kind of shell product design has a compact structure and high requirements for sealing. The whole machine's annual leakage requirements are strict. Once a large refrigerant leakage will affect the cooling effect of automotive air conditioning, which will seriously lead to air conditioning not cooling. For the lower shell, airtight inspection requirements generally to the pressure of about 3MPa, holding pressure time of about 2min conditions shall not leak. To achieve these leak detection conditions, slight fluctuations in the quality of the casting, it is easy to cause bulk leakage, which will seriously affect the host plant production schedule on schedule. Overall, the application of die casting gears in air compressors is a reliable and cost-effective solution for producing high-quality gears that meet the demanding requirements of industrial applications.
Requirement of Die Casting Gears in Air Compressors
The lower casing is an important part of an automobile air conditioner compressors, which has high requirements for its performance. The influence of casting gears shape structure and mold scheme design makes the casting easy to produce casting defects, which leads to the leakage of the product becoming scrap after machine addition and seriously affects the subsequent assembly work beat and progress.
The analysis result of the die casting system composed of mold and die casting gears machine, after the improvement of die casting mold pouring system, the filling speed of the mold is reduced down, while the filling time is shortened significantly, no sticky mold occurs again at the gate. The casting gears are effectively shrunken. The spraying time is also reduced to the normal level. The passing rate of the product in actual production is increased from 70% to more than 97%, thus significantly reducing the product cost. Sometimes this process is related to silica sol casting. Besides, this has greatly reduced the product cost, prolonged the service life of the mold, enhanced the market competitiveness of the product, and brought good economic benefits to the enterprise.
