Case Study

Toyokawa Engineering manufactures testing equipment for automotive parts and they use IMAO's Quarter Turn Fasteners on the fixtures in their equipment.
They designed the fixture to be able to hold several workpieces at a time to fit the user's needs.
Setups for changing fixture parts come out every changeover depending on workpieces.
The user required Toyokawa the swift changeovers of fixtures they do over 2 times a day.
That's why Toyokawa decided to use IMAO's Quarter Turn Fasteners that shorten the setup time by clamping with just a 90 degrees turn of the knob.
In the previous testing equipment, the user fixed the parts with screws and knobs and it took more than 1 minute for changeover.
With Quarter Turn Fasteners, changeover of fixture takes only 30 seconds.
Toyokawa highly esteems the quick & easy operation of IMAO's tool-less clamps, wide variation of line ups and their ready availability of IMAO's standard products as a manufacturer of standard machine elements.
Toyokawa will keep using Quarter Turn Fasteners for their equipment in the future.

Panasonic Eco Solutions Electrical Construction Materials Mie Co., Ltd. manufactures intercom and fire alarm for home and they use IMAO's Quarter Turn Fasteners on injection molding line for the resin products.
They cut the resin burr on back of the post-molded products by a nipper.
Setups for changing the nipper and its position come out every mold change because the position of the burr is different product by product.
In the previous line, they used the general-purpose nipper units for all products and it took more than 15 minutes to loosen screws, change nippers and adjust positions.
They needed to change the mold more than 50 times per month for some machines.
They decided to use dedicated nipper units for each product and clamp the units with Quarter Turn Fasteners to reduce machine downtime and set-up time.
As a result, the changeover of units takes only 1 minute with One-touch fasteners, Quarter Turn Fasteners.
Furthermore, the visible clamping and unclamping states by the position of the knob increased safety on their plant.
They will continue to improve production system by shortening the time for operation and changeover.
