Waste Dry Film Photoresist Dewatering Press

The TV-50F waste dry film photoresist dewatering press is designed to dewater waste photoresist generated from photoresist patterning processes, such as PCB manufacturing.

Waste Dry Film Photoresist Dewatering Press TV-50F

Today, one of the key challenges with business management is reduction of waste generated from production process. The TV-50F reduces waste photoresist with high dewatering capacity and helps reduce disposal cost. The TV-50F is compact: 844 mm long, 363 mm wide and 555 mm high. It does not require large space.


Waste Dry Film Photoresist Dewatering Press TV-50FThe TV-50F consists of a filter and two screws passing through the filter. The filter comprises two types of rings, fixed and moving rings. The screws convey and compact waste photoresist. The blades of the screws overlap each other. The rotating blades cut into the waste while the waste is flowing towards the outlet. This design helps achieve high dewatering efficiency and stable dewatering treatment.

Example of reduction in annual disposal cost of 3 million yen

Waste disposal cost is reduced by dewatering waste dry film photoresist containing photoresist remover and reducing the amount of waste to 30% to 65%*.
Reduction in the amount of waste will also shrink time required for transport and disposal.
*The reduction percentages vary depending on material to be dewatered.

Waste disposal cost

Example of disposal cost reduction

Production capacity 360,000 m2/year (30,000 m2/month)
Waste generation 60 t/year
Waste disposal cost 100 yen/kg or 20,000 yen/drum
Waste reduction by dewatering 50%
Dewatering capacity 30 kg-WET/h max.

*This cost estimate does not include transport, equipment maintenance, operation and running costs.

Easier handling of waste photoresist

Before dewatered, waste dry film photoresist is mixed with photoresist remover and the water content is very high. The waste is a strong alkali. It is hazardous and it must be handled carefully in transport and disposal not to spill it. The waste, after dewatered by the TV-50F, is like grated cheese and it won't drip the remover solution. That will improve the working environment for transport and disposal.
