Product Description
This is a part used in traditional fuel engine cars, oil pumps, its name is called flange bearing seat.
Mechanical Properties (GB/T 1176)
Single cast test rod, tensile strength ≥220MPa, bending strength ≥130MPa, elongation ≥3%, Brinell hardness ≥80HBW.
Casting Tolerance & Surface Finish
The casting tolerance shall be GB/T 6414-DCTG6-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.
Low Power & Surface Quality Requirements
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 ≤ Grade 3.
Machining & Loose Hole Restrictions
After the reference hole machine is added (after cutting about 1mm), no loose holes larger than 1mm² are allowed.
Material Regulations & Compliance
The substances used meet the requirements of GB/T 30512 and CE RoHS 2.0 regulations.
Development Background
New Customer Project
This is a new customer and the first time we have developed such parts.
Formal Agreements
After the background investigation of both parties, we signed the "Mold Development Agreement", "New Product Trial Production Agreement" and "Supplier Integrity Agreement" before development.
Short Development Cycle & High Precision
The development cycle of this product is short, with the first sample delivery time being 40 days. The product processing is difficult, with the mounting hole tolerance at ±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.
