We have released Tokidoki Tsushin VOL.24! 【Hotta Hagane Co., Ltd.】

A professional in special steel processing provides total support from materials to processing!

Our company collaborates with processing factories that possess skilled techniques in forging, heat treatment, drawing, and peeling to propose and respond to our customers' advanced requests. We have a well-equipped range of machining facilities, including the "LB EXII series," "QUICK TURN 250MY," and "QTE-200 SG." Additionally, we have expanded our CNC multi-tasking lathe with the "QT-250MY." With milling capabilities, it allows for both lathe processing and drilling. 【Processing Overview】 ■ Forging: Heating metal and shaping it into the desired form by striking it with a hammer or applying pressure. ■ Peeling: Rotating a cutting tool to shave the surface of the material. ■ Drawing: Passing the product through a die to finish it to the desired dimensions. ■ Heat Treatment: Hardening and tempering, normalizing, and annealing of materials. ■ Various Machining: Capable of lathe processing, BTA and gun drilling, and rolling processing. *For more details, please refer to the PDF document or feel free to contact us.

● To determine the sealing and waterproofing of sealed products based on pressure changes, it is not necessary to conduct tests that involve spraying water on the product or immersing it in water. ● Once the product is placed in a dedicated fixture within the inspection device, waterproofing can be quantitatively confirmed through automatic measurement. ● The target product size is W 300 × D 210 × H 100 mm or smaller. ● The target products include automotive cameras, smartphones, ECUs, small motors, and other packaging containers, and are effective for any products that require confirmation of sealing, waterproofing, and airtightness. ● For product specifications and details, please contact us.

In battery manufacturing lines, if components containing copper are used, there is a possibility that metal powder may mix in, dissolve, ionize, and pass through the separator, causing a malfunction that connects the positive and negative electrodes. Such minute metal powders may not be detected during pre-shipment inspections, and even if they are found, they can lead to various issues, such as the need to increase inspection processes to detect them. Therefore, Fukuda has developed a copper-free (all stainless steel) air leak tester that can be safely used in the production lines of battery manufacturers and secondary battery manufacturing equipment manufacturers. For product specifications and details, please refer to the "Related Product Information" and "Related Catalogs" below.

This is an air leak tester for battery cases of electric vehicles (EVs). The battery case has the characteristic of being "large with a significant internal volume, and its structure may deform due to internal pressure." As a result, air leak testing generates "noise caused by its large size and capacity" and "noise caused by expansion or deformation due to internal pressurization." To mitigate this noise, this device features a newly developed smoothing function and a linear fitting correction function used in combination during measurement. Additionally, to achieve low-pressure control that is difficult to manage and to expand flow for large volumes, we provide a bypass box (CBU-600) equipped with an electro-pneumatic regulator for precise pressure control and a pressurization valve with a large effective diameter to supply high flow rates. Measurement methods: Work-Work comparison, Work-Master comparison, Fixed Master comparison Measurement pressure range: 10 kPa, 20 kPa, 50 kPa (depending on specifications) Gauge pressure sensor accuracy: ±2% F.S. Differential pressure sensor accuracy: ±0.5% F.S. Group settings: 0 to 31 groups Power supply voltage / Power consumption: AC100 to 240 V / 100 VA

Fukuda's new flagship model. - Masterless type (FLA-0200 series) - General type (FLA-0201 series) Two models of air leak testers. With the mastering correction function, high-precision measurements can be achieved in a short time. Please take a look at the catalog.

● This is a leak testing device for small electronic components that does not use fluorinated inert liquids (PFAS-free). ● There is no longer a need for unstable visual confirmation through liquid immersion testing. It adopts a quantitative testing method that allows for stable pressure leak testing. ● It is a tabletop leak testing device specifically for gross leaks, with accuracy equal to or greater than that of liquid immersion testing. ● The detectable range is approximately 1×10⁻² Pa·m³/s to 1×10⁻⁶ Pa·m³/s (varies depending on the target product). ● It is suitable for sealed structures ranging from a few millimeters to a maximum of 80 × 70 mm.
