- Low Power Requirements: The surface of the casting is not allowed to have cracks, pores, feather crystals; small surface inclusions are not allowed, large surface inclusions are not allowed greater than 0.5mm²; grain size and porosity ≤3 grade.
- Machining Requirements: After the reference hole machine is added (after cutting about 1mm), no loose holes larger than 1mm² are allowed.
- Regulatory Compliance: 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 a mounting hole tolerance of ±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.
Frequently Asked Questions
What application is this flange bearing seat designed for?
This flange bearing seat is a precision component specifically engineered for use in oil pumps within traditional fuel engine automotive applications.
What are the mechanical property standards for this component?
It complies with the GB/T 1176 mechanical properties standard. Based on a single cast test rod, it achieves a tensile strength of ≥220MPa, a bending strength of ≥130MPa, elongation of ≥3%, and a Brinell hardness of ≥80HBW.
What are the casting tolerance and surface roughness specifications?
The casting tolerance meets GB/T 6414-DCTG6-GCTG7 specifications, and the outer surface roughness is maintained at Ra 6.3. Additionally, any residual convex of the runner and cap remains strictly within the blank tolerance range.
How do you control porosity and surface defects during production?
We enforce strict low-power requirements: no surface cracks, pores, or feather crystals are allowed. Small surface inclusions are prohibited, large inclusions must not exceed 0.5mm², and grain size/porosity is kept at ≤3 grade. After adding the reference hole (cutting approx 1mm), no loose holes larger than 1mm² are permitted.
Does this product meet environmental and material safety regulations?
Yes, all materials and substances utilized in the production of this flange bearing seat fully satisfy the requirements of GB/T 30512 and CE RoHS 2.0 regulations.
What is your development capability for complex OEM precision casting?
We offer strong OEM development capabilities, delivering high-precision results (such as mounting hole tolerances of ±0.012mm) within short development cycles (e.g., first sample delivery within 40 days). We provide fully integrated services from the initial blank casting to final precision machining.
