Geer shift sleeve Auto Transmission Parts for Surface treatment with Silicon casting Alloy steel

We offer a wide range of auto parts die castings. Includes shafts, cams, gears, ratchets, pinions, and levers, among other parts that perform mechanical functions. Containment such as end covers, motor housings, gear housings, plates, seats and gaskets are also common choices in metallurgical processes. The process is known for minimizing production costs for internal, external, helical, spur, face and wear gears. Most gear tooth profiles can also be cast, including those with helix angles of up to twenty degrees. Male threads up to 50 or inches are also cast free of flash to Class 2A tolerances without milling or cleaning, as are multi-start threads.

Specifications:

Description:

1. Tolerance of rough casting: Tolerances as low as 30 µm

2. Customer: China automotive
3. Field of application: passenger or freight train
4. Supply ability: 1,0000-20000pcs per month

5. Minimum Order Quanlity:100pcs

A common motivation for choosing a high-volume casting process is its potential to reduce unit prices. Many factors can affect manufacturing economics, including component complexity, alloy properties, die casting techniques involved, casting tool precision and cycle rates. One of the reasons die casting is economical is that one die cast part can often replace multiple parts. Additionally, it is often possible to incorporate certain features into die castings, eliminating secondary operations such as milling, boring, reaming, and grinding.

Competitive Advantage:

1. All of our products are strictly inspected and tested before packing in factory.

2. TS 16949 and ISO 9001 certified by TUV and PED certification by TUV.

3. The manufacturing process is investment casting and high precision machining in 4 axis machining

centers. Very modern inspection machine to keep the very narrow tolerance, and good position gauge

to keep correct position .

4. Tolerances as low as 30 µm are achieved without using expensive grinding processes.

5. First-class product quality and service by best facilities ,management and techniques.
