Target‑oriented cleaning performance for complicated internal oil passagesOur three‑series cleaning modes (vacuum hydrocarbon‑modified alcohol cleaning, CNC multi‑axis high‑pressure targeted flushing and multi‑tank ultrasonic washing) are purposely designed for intersecting blind holes and tiny throttle holes of valve plates. High‑frequency ultrasound, directional high‑pressure jets and vacuum‑assisted fluid circulation thoroughly strip embedded aluminum debris, sintered release‑agent carbon deposits and residual cutting fluid. It meets ISO‑16232 automotive cleanliness specifications and NAS‑7‑8 precision‑cleaning levels and prevents spool‑sticking failures caused by micro‑particles. Meanwhile, matched corrosion‑inhibiting detergents stop die‑cast aluminum from darkening or oxidation after cleaning.

Flexible options to match different‑volume production demands‑ For high‑end new‑energy vehicle and export‑grade valve‑plate projects, our fully‑sealed vacuum solvent cleaning system runs automatically with solvent distillation recovery rate above 98%, greatly cutting long‑term operating costs and complying with global VOC emission requirements.‑ For mass‑production by domestic OEMs, CNC programmable 6‑8‑axis equipment can switch working programs for different valve‑plate models quickly. Graded‑pressure control protects IT5‑IT6 precision spool holes against high‑pressure damage.‑ The multi‑tank ultrasonic cleaning line provides a budget‑friendly alternative for small‑and‑medium‑batch production with simple maintenance and a compact footprint.

High‑level automation and reliable inline monitoringAll equipment supports robotic loading‑unloading to connect seamlessly with upstream deburring and downstream leak‑testing and impregnation procedures for full‑line automatic production. Built‑in sensors continuously monitor solvent purity, filter clogging and cleaning‑cycle parameters in real‑time. Vacuum and hot‑air combined drying eliminates residual liquid inside deep holes completely so no water stains remain.

Professional supporting technical services beyond equipment supplySinobakr runs an in‑house cleanliness‑testing laboratory that conducts particle‑size analysis and particle‑weight testing following ISO‑16232 standards and issues official test reports. Custom‑formulated detergents are developed against your specific release agents and cutting oils. We also offer free program upgrades, proper filter‑element selection and valve‑plate trial‑cleaning services throughout the equipment lifecycle, together with overall layout consultation for your whole production line.

Cost‑efficiency and compliance advantagesCompared with traditional single‑ultrasonic or simple spray‑washing equipment that often results in rework, our solutions reduce reject rates significantly. The closed‑loop solvent recycling system minimizes consumable consumption. All models satisfy local environmental‑protection regulations for VOC emissions to help factories pass factory‑audit from well‑known automotive clients such as Bosch and Volkswagen.
