Flange Bearing Housing - Precision Copper Alloy Casting Factory in China | Reliable Suppliers for Oil Pump Components
Product Description
GB/T 1176, single cast test rod, tensile strength ≥220MPa, bending strength ≥130MPa, elongation ≥3%, Brinell hardness ≥80HBW.
GB/T 6414-DTCG6-GCTG7, outer surface roughness Ra 6.3. The residual convex of runner and cap shall be within the blank tolerance range. Pits shall not affect the size evaluation of the machine, and there shall be no casting defects that affect the use function.
The surface of the casting is not allowed to have cracks, pores, or feather crystals. Small surface inclusions are not allowed, and large surface inclusions are not allowed greater than 0.5mm². Grain size and porosity must be ≤3 grade.
After the reference hole machine is added (after cutting about 1mm), no loose holes larger than 1mm² are allowed. The substances used meet the requirements of GB/T 30512 and CE RoHs2.0 regulations.
Development Background
- This is a new customer and the first time we have developed such parts.
- After the background investigation of both parties, we signed the "Mold Development Agreement", "New Product Trial Production Agreement" and "Supplier Integrity Agreement" before development.
- The development cycle of this product is short, the first sample delivery time is 40 days, and the product processing is difficult, with the mounting hole tolerance being ±0.012mm.
- From the beginning of receiving the development notice, we were led by the project department and personally participated by the boss. After several rounds of meeting evaluation and on-site verification, we invested in new processing equipment, and finally completed the customer's requirements when sending samples for the second time.
Our company has a strong technical development team, with the ability to develop OEM parts in the field of precision casting, and provide integrated services from blank to machining; Excellence, to provide customers with efficient, quality products and services has been our philosophy.
