CNC Machining of Billet Aluminum Oil Pan with Cooling Fins

Tags: , , , , ,
CNC machined billet aluminum oil pan with integrated cooling fins and black anodized finish.

The component shown is a high-performance Custom Aluminum Oil Pan designed for automotive racing applications. Unlike traditional cast or stamped steel pans, this billet unit is machined from a solid block of Aluminum 6061-T6. This manufacturing method ensures superior structural integrity, eliminating the risk of porosity-induced leaks and providing greater resistance to road debris impact.

Our CNC Machining Solution

We processed the aluminum billet using multi-axis CNC milling to create the integrated cooling fins and precision mounting features. The design includes extensive fin structures to increase heat dissipation, while maintaining a rigid, leak-proof structure.

Critical sealing surfaces and mounting holes were machined to strict tolerances to ensure proper fitment. Finally, the component was treated with a black anodized finish to improve corrosion resistance and thermal efficiency. We successfully delivered the custom automotive part that met the client’s design specifications.

Our Manufacturing Capabilities

5-axis CNC milling machine cutting an aluminum block during the manufacturing process.

Capabilities include 3-Axis, 4-Axis, and 5-Axis CNC Milling, as well as CNC Turning operations. Standard materials processed include Aluminum alloys, Stainless Steel, Titanium, etc. and Engineering Plastics. Available secondary operations include Anodizing, Powder Coating, Bead Blasting, and Laser Engraving.

Capacity supports requirements ranging from single-unit Rapid Prototyping to Low-Volume Production runs (1-1,000+ units).

Factory Quality Assurance

Coordinate Measuring Machine (CMM) inspecting the dimensional accuracy of a custom CNC machined part.

A standardized Quality Management System (QMS) is applied to all manufacturing orders, regardless of part complexity or production volume. The following inspection stages are mandatory for every CNC machining project:

  • Material Verification: Raw material certification (chemical composition and mechanical properties) is verified upon receipt to ensure compliance with material specifications.

  • First Article Inspection (FAI): The first unit from any production run undergoes a full dimensional report to validate the machining setup and programming before volume processing begins.

  • In-Process Monitoring: Periodic checks are conducted during the machining cycle to monitor tool wear and ensure dimensional consistency is maintained throughout the batch.

  • Final Inspection: Completed components undergo a final dimensional and cosmetic verification using CMM (Coordinate Measuring Machine) and calibrated manual instruments prior to packaging.

FAQs About CNC Machining Services

No. We support projects of all sizes, from a single prototype unit to low-volume production runs.

Standard lead times are typically 10–15 business days. Expedited services (Rapid Prototyping) can be completed in as little as 3–5 business days, depending on part complexity and material availability.

In most cases, we source materials from our approved suppliers to ensure quality control. However, we can machine customer-supplied materials for specialized alloys or specific requirements upon engineering review.

Unless otherwise specified, our general tolerance standard is ISO 2768-m (±0.125 mm) for metals and ±0.25 mm for plastics. Precision tolerances ±0.005 mm are achievable but must be explicitly stated in 2D technical drawings.

Our facility can accommodate parts up to 4000 x 1500 x 600 mm for milling and Ø200 mm x 500 mm for turning.

Yes. We can install inserts (e.g., Helicoils, PEM fasteners) and perform basic mechanical assembly of machined components prior to shipment.

To provide an accurate quote, we require a 3D CAD file (STEP, IGES, or X_T format). If the part has threaded holes, tight tolerances, or specific surface finish requirements, a 2D PDF drawing must also be provided.

We take IP protection seriously. All files are stored securely, and we are willing to sign a Non-Disclosure Agreement (NDA) prior to receiving your data.

Yes. We can provide material certificates (COA) and dimensional inspection reports upon request. Please specify this requirement when placing your order.

We ship globally using major carriers (DHL, FedEx, UPS). Shipping terms are typically Ex Works (EXW) or DAP, depending on the agreement.
