• Gas recovery/treatment equipment

This device is a machine that determines leaks by sealing a workpiece with a constant air pressure (0.1 to 0.5 MPa) and measuring the change in internal pressure (pressure loss) for a set period of time (1 to 5 minutes). *Direct pressure leak test Unlike traditional immersion tests, this method allows for inspection of the workpiece in a dry state, enabling numerical management of leaks and high-precision testing in a short time. **Advantages of Air Leak Testing** 1. Improved work efficiency... Unlike visual inspection through immersion, there is no need for a drying process, the workpiece remains clean, and the operation is simple. 2. Enhanced inspection accuracy... By quantifying leak standards, judgments are made solely based on settings, improving quality. Additionally, there is no need for skilled inspectors, allowing anyone to make accurate determinations without relying on human senses. 3. Reduction in labor costs and running costs... The operation is simple, inspection time is shortened, and maintenance is easy.

Our company's core wire winding machine is a device that binds the core with thin iron wire instead of using a brazing jig. By using a tensioned thin wire, the need for cleaning and maintenance of bulky brazing jigs is eliminated, allowing for more effective use of available space in the factory. Additionally, the absence of burn marks from brazing jigs improves the appearance. The advantages of brazing with wire include a reduction in the amount of oxygen brought into the NB furnace compared to using jigs, which also extends the lifespan of the mesh belt, thereby increasing brazing efficiency. Furthermore, heating the wire requires less energy than heating the jig, resulting in lower energy costs for the furnace. Our equipment features servo control for core compression and wire chucking, and with a touch panel for vehicle type changeovers and jig replacements in just a few minutes, work efficiency is also improved.

We assist in achieving in-house helium recycling at a low cost through the operation of helium leak testing equipment. Case Study> Company A in Aichi Prefecture They have already applied low-concentration mixed He gas in helium leak testing, achieving over 80% reduction compared to using 100% helium. However, due to being in a mass production line, they were purchasing 1 million yen worth of helium per month for one production line, and with the soaring helium prices, the costs rose to 1.6 million yen per month! With concerns over helium supply, there was a need to further reduce helium purchasing costs! By introducing Logic's mixed gas, high-pressure, large-capacity helium recovery system, helium purchasing costs were reduced to 320,000 yen per month, achieving an 80% cost reduction! This is amazing!
