MT-75

Wash, rinse and dry tanks side by side on one frame; the operator moves the basket from station to station.

Each station has its own timer, temperature and ultrasonic controls. The operator lowers the basket, starts the station, and carries it on when the cycle ends.

The most economical way to a clean and dry part: suited to small batches, frequent changes of part family and workshops where an operator is at the line anyway. Tank sizes, frequencies and the number of stations are chosen per project.

• Multi-tank lines: wash, rinse, dry

Each station gets its own lift: it lowers the basket, moves it up and down during cleaning and lifts it to drain. The operator only moves the basket on.

The lift makes every cycle the same: immersion, oscillation during the ultrasonic stage and the drain time are programmed per station, so the result no longer depends on the operator.

A good fit for heavy baskets and repeated batches that do not justify a transport robot. Stations can later be linked into a fully automatic line.

• Multi-tank lines: wash, rinse, dry

A servo-controlled transport carriage takes the basket from loading to unloading through every station under a PLC programme.

The carriage picks the basket at the loading position, lowers it into each tank in turn, oscillates it during the ultrasonic stages, lets it drain and sets it down on the unloading side. Soft start and stop protect sensitive parts.

A Siemens PLC with a 7- to 19-inch touchscreen, sized to the line, holds a programme per part family: times, temperatures and agitation per station, with real-time monitoring. Built for continuous production with minimal operator intervention.

• Multi-tank lines: wash, rinse, dry

Typical sequence: pre-wash, ultrasonic wash, one or two rinses, drying; optional passivation or rust protection.

Pre-wash or degreasing takes the gross soil off first, so the ultrasonic tank stays clean longer. The ultrasonic wash removes the fine soil. Rinses take the detergent film off; a final rinse in demineralised or RO water prevents water spots. Drying ends the line.

Optional stations add passivation, rust protection after the rinse, or a second drying stage for parts with deep bores.

Tank size, ultrasonic frequency and power are set per station: 28 kHz for heavy soil, 40 kHz for fine cleaning, 80 kHz for delicate parts.

Each tank is sized from the largest part and the basket, not from a catalogue. Strong 28 kHz cavitation suits a pre-wash with oil, polishing paste and chips; 40 kHz cleans small, fine detail; higher frequencies are gentle enough for polished and delicate parts.

The MT-75 reference line uses tanks of about 75 litres with 40/80 kHz; larger and smaller tanks are built to order.

• How to size an ultrasonic tank

Recirculating filtration per tank, oil skimmers, and rinse water from RO or deionised supply keep the baths clean and the rinse spot-free.

Each ultrasonic and rinse tank can have its own multi-stage filtration, down to fine cartridges for the final rinse, with overflow edges that carry floating soil away.

For water-intensive lines: reverse osmosis, deionisation or distillation recover and reuse rinse water; heating and chilling hold each bath at its set temperature.

• ST or SF: when the bath needs its own filtration

Hot-air drying with forced circulation, optionally filtered air or a swinging basket for parts with blind holes.

Drying runs with hot air at 60 to 100 °C with forced circulation and an insulated chamber. Filtered air keeps particles off cleaned parts.

A swinging or tilting basket in the dryer turns blind holes and cavities so the water runs out instead of standing in them.

• Dryer tanks: the DT series after the wash and rinse

Programme selection by barcode, automatic detergent dosing, cycle logs and remote monitoring over your network.

Scanning a batch or part code selects the right cleaning programme. Dosing tops up the detergent by time or conductivity, with low-level alarms.

Cycle logs with time stamps, filter changes and alarms can be exported or read remotely over the network.

Stainless steel throughout: AISI 304 as standard, AISI 316L or duplex where the chemistry needs it.

Tanks, frame and covers are stainless steel with smooth welds. AISI 316L or duplex steel is used for acidic or chloride-containing chemistry, for example in passivation.

Lids, exhaust connections, insulation and safety guarding are part of the design, and the line is laid out to fit your floor and loading direction.
