Flexible machining of small die-cast components for automotive hydraulic valve bodies

Flexible machining of small die-cast components for automotive hydraulic valve bodies

Automotive hydraulic valve bodies and control valves are core precision components that are universally used in both new-energy vehicles and conventional gasoline-powered cars, finding extensive application in braking, steering, and hydraulic control systems. These small die-cast parts are compact in size, feature densely spaced holes, and have intricate internal cavity structures, placing extremely stringent demands on sealing performance, hole‑diameter accuracy, and surface quality.

Meanwhile, valve-body components come in a wide variety and undergo rapid iterations, with most companies relying on multi‑product, small‑to‑medium batch production. The traditional single‑machine machining approach is cumbersome when switching between part types, features long setup and debugging cycles, and delivers low productivity—making it difficult to keep pace with today’s highly flexible and dynamic order‑driven market.

Shenming Technology Addressing the pain points of flexible mass production for small automotive parts, we have developed a precision machining solution that supports multiple part varieties and enables rapid tooling changes, perfectly meeting the demands for efficient, agile mass production of valve‑body components.

Workpiece

Aluminum alloy die-cast hydraulic valve bodies, brake control valves, and precision small valve components—compatible with both new-energy and fuel-powered vehicles.

Processing pain points

1. The workpiece features densely spaced holes and a precision internal cavity, with stringent sealing requirements; even minor machining defects can render the product scrap.
2. A wide variety of product categories and small order sizes result in frequent changeovers, leading to production interruptions and low efficiency.
3. Traditional standalone machining relies on manual labor, resulting in unstable cycle times and difficult-to-control production capacity.
4. There are many non-standard workpieces, general-purpose fixtures have poor adaptability, and setup costs are high with long lead times.
