Sinobakr hydrocarbon cleaning machines integrate vacuum technology, variable-frequency ultrasonic waves, spraying and vapor bath composite processes. The vacuum negative pressure eliminates air blockages inside blind holes, deep holes and intersecting oil passages. Ultrasonic cavitation penetrates tiny crevasses to efficiently remove cutting oil, grinding compound, polishing wax and micron-sized metal debris. Workpieces undergo low-temperature vacuum drying after cleaning, leaving no watermarks or solvent residues on surfaces. Hydrocarbon solvent is mild and non-corrosive to aluminum alloy, stainless steel, bearing steel and powder metallurgy parts without hydrogen embrittlement, and offers short-term rust protection. The cleanliness level can reach NAS 7~8, meeting micron particle control requirements for automotive, aerospace and hydraulic industries.

The equipment is eco-friendly and energy-saving with low operating costs. It is equipped with an automatic vacuum distillation and regeneration system, achieving over 99% solvent recovery rate. The hydrocarbon solvent can be recycled repeatedly with only minor replenishment and minimal waste liquid output. A dual-stage VOC treatment unit with activated carbon and catalytic oxidation is standard, ensuring exhaust emissions well below national limits and facilitating environmental assessment approval. No large wastewater treatment infrastructure is required, and long-term consumable costs can be reduced by more than 40% compared with conventional water-based cleaning.

Full explosion-proof design ensures controllable production risks. The whole machine complies with Ex IIB T4 explosion-proof grade, fitted with explosion-proof motors and electric control components. Indirect heating via thermal oil is adopted. Imported solvent-resistant fluororubber seals are used on the chamber to prevent solvent leakage. An online flammable gas monitoring module triggers automatic alarm and shutdown when concentration exceeds the threshold. The workshop environment has no pungent odour, complying with fire codes for continuous factory production.

Modular design and high automation enable easy integration into smart manufacturing lines. The complete product portfolio includes single-chamber standalone units, tumbling models and multi-station automatic cleaning centres, customizable according to customer production capacity. Controlled by Siemens PLC and touchscreen with programmable and storable processes, the machine performs fully unmanned operations: automatic loading, rough cleaning, fine cleaning, vapor bath treatment, vacuum drying and automatic unloading. It can connect with robotic arms and conveyor lines to support flexible production of multiple product types, compatible with standalone installation and full automated production lines.

Self-developed domestic technology delivers high cost-performance and one-stop supporting services. As a national specialized, sophisticated, distinctive and innovative high-tech enterprise with over 20 years of experience in industrial cleaning, Sinobakr independently develops core vacuum distillation and ultrasonic systems, comparable to imported equipment such as FinnSonic. At equivalent cleaning precision, it features much lower procurement and spare part costs as well as faster after-sales response than imported alternatives.

Sinobakr operates an in-house cleanliness testing laboratory. We provide sample cleaning tests, formal cleanliness inspection reports, on-site installation and commissioning, process development and long-term maintenance services. The machine comes with complete warranty, readily available spare parts and on-site inspection service to deliver comprehensive cleaning solutions.

A full set of international certifications including ISO9001, CE and UL is available. Manufactured in China, the machines meet compliance requirements for overseas factories and are suitable for cleaning processes of export components.
