During die‑casting production, workpieces always suffer from release‑agent residue, aluminum scraps, carbonized oil and oxide layers. Narrow blind holes and gaps trap contaminants. Conventional cleaning methods often lead to incomplete decontamination, aluminum‑alloy darkening, water‑marks and inconsistent cleanliness, which badly affect later painting, sealing and assembly quality.

With long‑term R&D experience in industrial cleaning, Bakr supplies tailor‑made full‑set solutions for aluminum‑zinc die‑cast parts, including ultrasonic washing, high‑pressure spraying, vacuum hydrocarbon cleaning, multi‑stage rinsing and vacuum‑drying equipment matched with environment‑friendly special detergents. By ultrasonic cavitation and high‑pressure impact, our system thoroughly removes stubborn dirt inside deep holes. Fully‑automatic production lines connect with customers’ automated workshops to finish washing, rinsing, drying and passivation continuously and avoid water‑marks. Cleaning agents can be recycled with low‑VOC emission. Our solutions ensure effective cleaning and base‑material protection while meeting environmental‑protection rules. They help die‑casting manufacturers raise qualified‑product rate and cut down labor‑cost and rework‑expense to achieve green manufacturing。
