Compressors & Gears
Rayforce's metal casting gears can be applied to Turbo blowers, air control component, piston compressors, casting gears, etc.
Application of Casting Gears in Air Compressors
With the continuous development of the automotive industry, the efficient high precision die casting production process 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 a compact structure, 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 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.
Requirement of Casting Gears in Air Compressors
The lower casing is an important part of automobile air conditioner compressor, which has high requirements on 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 to become 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 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. 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.
