Castem Co., Ltd. showcases ultra-fine processing technology at MECT2025, featuring an exhibition of miniature surgical instruments and mold processing demonstrations.
Castem Co., Ltd. will exhibit at "Mechatrotech Japan 2025," which will be held at Port Messe Nagoya from October 22 (Wednesday) to October 25 (Friday), 2025. In the themed exhibition zone "Processing Techniques Supporting Healthcare," we will showcase a miniature model of a laparoscopic surgical instrument (forceps) that has been meticulously crafted. In collaboration with ROKKO Smart Technology Co., Ltd., we will demonstrate the mold processing of the finest components of this miniature model using the ultra-high precision high-speed micro-machining machine "Android3." Attendees will have the opportunity to directly experience our "technological prowess encapsulated in a tiny world." We invite you to stop by during this special occasion! 【Exhibition Overview】 Date: October 22 (Wednesday) to October 25 (Saturday), 2025, 10:00 AM to 5:00 PM Venue: Port Messe Nagoya (2-2 Kanjo Futo, Minato Ward, Nagoya City) Exhibition Location: 3rd Exhibition Hall, Concept Zone A Content: Organizer's planned exhibition "Machining Live! Processing Techniques Supporting Healthcare - Learning Success Tips from Different Industries -" - Display of a laparoscopic surgical set approximately 95 mm in length - Demonstration of mold processing using Android3 and seminars - Display of other miniature products, MIM products, digital cast products, etc.
