Registered the explanatory materials on efforts regarding the quality of stainless steel containers.

We have summarized two tests conducted at our company: the "penetrant testing" of stainless steel containers and the "pressure vessel inspection."

Our company conducts various inspections to maintain the quality of our products. Additionally, if requested by customers, we may perform inspections tailored to their preferences. Here, we will introduce the color check (penetrant testing) and the inspection of pressure vessels among the inspections of our stainless steel containers. However, what is written here represents only a portion of the inspections we conduct, and in reality, there are many other types as well. We hope this explanatory document will serve as a reference when considering stainless steel containers.

This is an introduction to the identification management methods for stainless containers (stainless steel products) conducted as part of quality control.

"Identification management" is one of the essential management practices in product manufacturing. In factories, identification management as part of quality control is likely implemented in various situations, such as with materials and manufacturing processes. While the management methods vary depending on the factory and product, it is necessary to choose the optimal identification method suited to the environment. Here, we will introduce the identification management methods for stainless containers (stainless steel products) used in various situations, including raw material storage, production lines, and integration into machinery.

BA material, 2B material, buff polishing, electrolytic polishing... A grand reveal of stainless steel surfaces that cannot be discerned by the naked eye!

Smooth, rough, silky... Depending on the material and surface finish, stainless steel shows various appearances. However, it is not possible to see what the actual surface looks like just by visual inspection. Therefore, this time, we will introduce photographs of stainless steel surfaces taken using a scanning electron microscope (SEM). *What is a scanning electron microscope (SEM)?* Unlike optical microscopes (such as magnifying glasses and general microscopes) that use light, a scanning electron microscope uses electron beams. It allows us to clearly see fine surface structures that cannot be observed with optical microscopes.

Stainless steel is a metal that is "difficult" to rust!

We sometimes receive inquiries from customers saying, "Even though it's made of stainless steel, it rusted quickly." Stainless steel, as the English words "Stain (rust, corrosion) + less (less) + steel (steel)" suggest, is an alloy of iron that is highly resistant to rust. While it is much less prone to rust compared to regular iron, it is not completely rust-proof. This PDF document summarizes "Why is stainless steel resistant to rust?", "What causes rust on rust-resistant stainless steel?", and "What are the rust prevention measures for stainless steel containers?" You can view it immediately by downloading the PDF.

I have summarized the important cleaning methods to make stainless steel containers last longer.

After using a stainless steel container, it is essential to clean the container. However, incorrect cleaning methods can cause scratches or lead to rust. Here, we will introduce important cleaning methods to help prolong the life of stainless steel containers.

Easy to wash without tools and essential for containers and piping: a summary of the mechanism and related products of "Herl fittings."

When flowing or pouring water and raw materials into stainless steel containers or equipment, I believe that pipes and valves are connected to the containers or equipment. When connecting these, threaded fittings such as sockets and nipples, as well as "fittings" like flanges and hygienic fittings, are used. Here, we will introduce "hygienic fittings," which are used in processes that require a more sanitary environment, including their applications, types, and related products.

[To the owners of parking lots and parking lot construction companies] "I'm worried about the possibility of colliding with pedestrians when exiting the parking lot..." Among vehicle entrances to parking lots, stores, residences, and factories, those facing sidewalks or roadways are particularly prone to dangerous incidents such as collisions with pedestrians or between vehicles. To alleviate such concerns, Hotron proposes a [Vehicle Exit Warning Sensor] that detects vehicle departures at various sites and alerts the surroundings with LED lights and buzzers. The system consists of a simple configuration of "Sensor" + "Controller" + "Switching Power Supply (24V)" + "LED Rotating Light." *When using the exit warning system, we kindly ask customers to arrange for the switching power supply (24V), LED rotating light, control panel, circuit breaker, etc. Since it can be retrofitted, it can also be used for existing parking lot entrances. [Contents Included] ○ Vehicle Exit Warning System Configuration ○ Comparison Table of Exit Warning Sensors ○ Four Modes ○ Wide Range of Applications ○ Customer Feedback ○ Appearance Diagram / Specifications ◎ For more details, please contact us or download the catalog.

In recent times, there has been a growing interest in infection control measures and facility hygiene management. Our company offers non-contact sensor products that are recommended for commercial facilities, food factories, and nursing and caregiving facilities. 【Sensors for Automatic Doors】 ● Light Touch Sensor HA-T401 … When you wave your hand in front of the automatic door, the sensor detects the movement and opens or closes the door. It is recommended for making doors that use touch switches non-contact. ● Hand Wave Sensor PF-R5, PF-U2, DHS-1 … Opens and closes the automatic door by waving your hand in front of the sensor. ● Foot Switch PF-01S/01D/03S/05 … Opens and closes the automatic door by placing your foot in the opening. 【Access Control System】 ● Face Recognition + Unmanned Temperature Measurement DS Series … Capable of detecting mask-wearing and measuring body temperature simultaneously with face recognition. ● Automatic Disinfectant Spray Dispenser PHW-03B … Automatically sprays disinfectant when you wave your hand in front of the sensor. 【Nursing and Care Sensors】 ● Infrared Bed Exit Sensor "Just Place It Pole-kun" … This bed exit sensor is installed next to the bed and alerts via nurse call when the subject enters the detection range. ◎ For more details, please download the catalog or contact us.

● 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.

The "Mechanical Stitching Method" by Nichinichisui Road Machinery Co., Ltd. is a new technique that allows for the repair of metal cracks without the application of heat. By using special bolts and reinforcement plates, cracks are physically removed, and repairs are made without causing any thermal impact on the base material. Repairs can be carried out in environments where open flames cannot be used. Since no heat is applied, the disassembly of equipment is minimized. ◎ For more details, please contact us. ◎ If a detailed technical explanation is needed, please contact us.
