Business Technology introduction

Round Trim® (Burrless cutting process)

Technology that only Nissin can provide: This is a unique Nissin processing method that does not produce burrs when cutting metal materials with a press. Burrs can affect the quality of car batteries, so deburring was previously required after press processing, but this method provides high-quality products without burrs by pressing alone.

(Example of burr-less processing)

Technology that only Nissin can provide: Products that used to be manufactured by welding or cutting have now been integrated into press production. It is characterized by a thick tapped part, but the thickness is ensured by locally consolidating thin materials, and the tapping process is finished by press working.

(Product cross section)

Technology that only Nissin can provide: The product, which used to consist of two parts, has been made into an integrated press production system by cold forging it from a rod-shaped material that is different from plate material. We use computer simulation to analyze press processing and select the optimal material shape. With this product, we have achieved improved product strength by integrally forming it.

Technology that only Nissin can provide: Processes plate-shaped materials with a thickness of approximately 0.1 mm to 2.0 mm into cylindrical shapes without breaking them. Used in a wide range of areas in automobiles. We have a track record of processing products with a height of 80mm.

Technology that only Nissin can provide: We perform corner drawing, which is considered to be one of the most difficult drawing processes. The difficulty is controlling the material thickness at the four corners. A special mechanism built into the press machine allows you to freely process the shape of the end face on the opening side.

Technology that only Nissin can provide: By processing products after pressing, we provide added value such as hardness adjustment, improved appearance quality, and improved cleanliness. We perform appropriate processing according to the functions used by our customers.

(Processing equipment)

Technology that only Nissin can provide: We are promoting the automation of visual product inspection and tray alignment using cameras and sensors, which used to be done manually. By operating robots, we have achieved improved productivity and stable quality control. Automation of appearance inspection is an effort to prevent defects from leaking out, but as an effort to prevent defects from occurring, we are incorporating cameras and sensors into press molds to detect signs of defects.

Technology that only Nissin can provide: This is an automated production line from pressing to post-processing, inspection, and packaging. Each process is connected by a conveyor and transported automatically, so there is no work-in-progress, making it an extremely efficient integrated production system. Several types of parts are required to be packed in one tray, but several types are processed simultaneously using a press, and a robot takes them out of the mold and transports them to the tray. Because it eliminates the risk of out-of-stock items, our customers have praised our production line as safe and efficient.
