Sinobakr provides three core solutions for engine housings (cylinder blocks/cylinder heads, aluminum/cast iron materials, with dense blind holes & cross holes, mixed contaminants of oil dirt, metal chips and burrs): hydrocarbon vacuum ultrasonic cleaning, water-based high-pressure spray cleaning, and CNC high-pressure deburring cleaning. It covers the full closed-loop process of precision cleaning, deburring, drying and solvent recovery, meeting the high cleanliness standards of VDA19/ISO 16232 and mass production requirements.

1. Core Pain Points & Solution Selection

Typical Contaminants

• Machining residues: Cutting fluid, emulsified oil, iron/aluminum chips, burrs on cross holes, threaded holes and blind holes

• Heat treatment & assembly contaminants: Rust preventive oil, greasy dirt, carbon deposits, dust

• Cleaning difficulties: Residues in deep/blind holes, orifice burrs, aluminum surface protection, consistent cleaning effect in mass production
