PPS resin is one of the high-performance engineering plastics known as “super engineering plastics” among thermoplastic resins. PPS is an abbreviation for “polyphenylene sulfide”. It is used in a wide range of fields due to its excellent heat resistance, cold resistance, and chemical resistance. However, PPS resin is prone to gas generation, and the resin…続きを読む
There are many processes that generate foil burrs, such as in-mold printing, decorative printing, and hot stamping. Or, the metal foil burrs on semiconductor parts can also destabilize quality. Blue Star R&D removes burrs and cleans them by controlling the positive and negative impact forces of the cavities (micro vacuum nuclei) generated by ultrasonic waves.…続きを読む
Ultrasonic cavitation application technology has made great progress over the past few years. The diameter of cavities (microvacuum nuclei) generated by ultrasonic waves has changed from 0.5 mmΦ in conventional ultrasonic cleaning to nowadays, huge cavities with a diameter of 10 mm are available. The impact energy is cubic times the diameter. 超音波キャビティーション応用技術・バリ取り、研磨、鋳砂除去 en-US
BlueStar has developed and begun supplying a deburring and cleaning system for precision stamped parts such as leadframes after stamping. The system can be installed in the middle of a reel-to-reel feeder and winder, or in the post-press process. The liquid used should be a hydrocarbon solvent if there is a large amount of mineral…続きを読む
An ultra-compact, 83 mm diameter ultrasonic deburring unit will be exhibited and demonstrated alongside FANUC cooperative robots at the Mechanical Components & Materials Expo to be held at Tokyo Big Sight at the end of June 2022. A powerful newly developed HDB ultrasonic diaphragm is used. We will show you the pioneer of the age…続きを読む
Powerful ultrasonic waves for deburring generate numerous spherical nebula cavities (microvacuum nuclei) with a diameter of up to 10 mmΦ. At this time, a banging sound like a kind of thunder discharge is emitted. To block this sound inside the equipment and prevent it from leaking into the working environment, we have been producing our…続きを読む
