GTX-400 open type high speed press
1. Our company uses GTX-400 open high-speed press, focusing on mass production of medium-precision motor cores. The equipment has a punching rate of 200 times/minute, a repeat positioning accuracy of ±0.03mm, and is suitable for punching 0.35-0.5mm silicon steel sheets and cold-rolled plates. After manual adjustment, the punching burr is ≤0.03mm (meets the industrial-grade G3 standard), and the stacking coefficient is ≥0.95. The manual mold change time is ≤20 minutes, and manual sampling (micrometer + projector) is performed every hour to ensure the dimensional tolerance of ±0.05mm and the flatness ≤0.1mm/100mm. We have stably supplied 800,000 cores to a certain industrial motor customer, with a qualified rate of 99%, a material utilization rate of 92%, and a mold life of more than 2 million punches. The processing cost of a single piece is 0.15 yuan/piece, and it supports 96-hour emergency delivery. It is suitable for small and medium-sized variable frequency motors, household appliance motors and power tool cores. The weight tolerance is ±0.8%, taking into account both efficiency and economy, and providing medium-sized customers with cost-effective precision blanking solutions.
