Automotive aluminum die‑cast components are key parts for vehicle lightweighting, including gearbox housings, water pump housings, motor housings, valve covers and other precision components. After die‑casting and machining, die‑casting flash, fine aluminum chips, machining burrs and release‑agent oil tend to remain on parting lines, cross‑holes, blind holes, thread grooves and narrow interlayers. Conventional processes such as ultrasonic cleaning, manual grinding and fixed‑spray cleaning can only remove surface contaminants. They fail to eliminate hidden burrs and impurities inside internal passages. This results in insufficient cleanliness, workpiece scratches, thin‑wall deformation, and burr‑falling induced hole blockage. These issues seriously compromise assembly accuracy and vehicle reliability, and cannot meet stringent mass‑production standards of the automotive industry. To tackle deburring and cleaning challenges for die‑cast parts, Sinobakr has developed a dedicated CNC high‑pressure deburring & cleaning solution, delivering an efficient one‑stop solution for precision mass production of die‑cast components.

This solution is equipped with a 3‑5‑axis CNC linkage system supporting independent programming of motion trajectories. Cleaning paths can be pre‑configured according to the 3D geometry of various automotive die‑cast parts, enabling precise nozzle positioning and multi‑angle targeted spraying during operation. Adopting variable‑frequency high‑pressure water‑jet technology with adjustable pressure ranging from 30 MPa to 50 MPa and wear‑resistant gem nozzles, it performs spraying at 0°, 45° and 90° angles. High‑pressure jets reach deep into inaccessible deep holes, intersecting oil galleries, parting gaps and threaded cavities to impact burr roots, thoroughly stripping fine aluminum residues, casting particles and stubborn grease. No cleaning dead zones are left, while thin‑wall aluminum substrates remain undamaged with dimensional accuracy and surface flatness well‑preserved.

Adopting an integrated closed‑frame design, the machine combines high‑pressure deburring, precision washing, pure‑water rinsing, oil‑water separation, multi‑stage filtration and hot‑air drying in one unit. All processes are completed in a single clamping without secondary handling, greatly simplifying production workflows. Fitted with an intelligent water‑circulation filtration system and magnetic chip‑removal device, multi‑stage fine filtration enables water recycling and effective separation of aluminum chips and oil, cutting water and consumable costs and complying with environmental requirements for modern smart factories. The unit supports stable 24‑hour continuous operation with low failure rate and easy maintenance, ideal for high‑volume inline production.

Compared with traditional methods, the Sinobakr CNC high‑pressure solution addresses major industry pain points including residual internal burrs, inconsistent cleanliness, high labor cost and low throughput. It flexibly accommodates automotive aluminum die‑cast parts of diverse sizes and geometries and supports non‑standard customization for both component workshops and large OEM plants. Fully automated CNC operation eliminates human errors, improves product yield and consistently meets micro‑level high‑cleanliness acceptance criteria for auto parts.

Centered on precise numerical control and high‑pressure water‑jet technology, Sinobakr’s dedicated solution realizes integrated deburring, chip removal, degreasing and drying for die‑cast parts. Balancing cleaning performance, productivity and energy efficiency, it helps automotive die‑casting manufacturers reduce costs, raise efficiency and strengthen product quality and market competitiveness.
