八幡ねじ List of Products and Services

Our company has developed an in-house "bagging system" that focuses on "quality" and "cost" to solve the challenges of screws and assemblies. We achieve high-quality control with two sensors. The "counting sensor" captures products on a surface and can detect products falling while rotating, while the "weight sensor" inspects the total weight of the bagged items and performs the final check. We bag everything from "general items" to "special processed items" sourced through our network. Our standard machine can bag up to four parts. For five or more parts, please consult us. 【Features】 ■ Counting Sensor - Captures products on a surface and can detect products falling while rotating - Allows for quantity setting and counts the products being bagged ■ Weight Sensor - Inspects the total weight of the bagged items and performs the final check - Abnormal items are automatically ejected to prevent mixing with good products *For more details, please refer to the PDF document or feel free to contact us.
