We meet high demands by performing cleaning, inspection, and packaging of screws in our own clean room. We are particularly particular about our cleaning machines, and by adopting a horizontal transport method and a quick dumping method for each cycle, we have achieved a groundbreaking level of cleanliness for screw cleaning. Stainless steel parts used in various fields such as medical, food, semiconductors, hard disks, and automobiles are extremely sensitive to burrs, dirt, and residues. By implementing this processing procedure, significant reductions are possible. 【Equipment】 - Chemical polishing equipment - Ultrasonic pure water cleaning equipment - Particle counter - Ion chromatography ◇◆◆◇◆━━━━━━━━━━━━━━━━━━━━━━━━━ There are very few screw manufacturers with their own clean rooms. Please take a look at our technical capabilities in our catalog. Alternatively, feel free to contact us. ━━━━━━━━━━━━━━━━━━━━━━━━━◇◆◆◇◆
