[Custom Case] We have published a delivery case for a packaging container manufacturer.

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.

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.

A guidebook that can be used for in-house study sessions! It provides a simple and detailed explanation of surface treatments for stainless steel plates and stainless steel containers (electropolishing, fluororesin coating).

The 'Secret Notebook Full of Information on Stainless Steel and Surface Treatments (Electropolishing and Fluororesin Coating)' is a document that introduces the electropolishing and fluororesin coating of stainless steel and stainless containers used by MONOVATE. Regarding stainless steel, we explain the symbols SUS304, SUS316, and SUS316L. Our company manufactures containers from these stainless steel plates, primarily providing them to pharmaceutical manufacturers, as well as cosmetics, food, and chemical manufacturing companies. For electropolishing, we present the methods for electropolishing the stainless steel (SUS304, SUS316L) we use, along with the characteristics demonstrated by the electropolishing process. Additionally, we explain the characteristics of fluororesin coating and the selection of materials for it. *This document can be viewed immediately from the [Download] section.

We will introduce a custom-made case of Inconel products that were completely made-to-order and delivered!

Our company manufactures products using stainless steel, but recently we have seen an increase in the design and production of Inconel (Hastelloy) containers. Here, we would like to introduce examples of custom-made Inconel products that we have manufactured and delivered as completely bespoke orders!

We are conducting demonstrations and experiments with stainless steel containers! Here are three examples summarized from past experiments!

1. Pressure Transfer of Gyoza Filling Nitto Metal Industry Co., Ltd. offers rental of demonstration machines. This time, we received a request from a food user to create a container for transferring gyoza filling under pressure, and we will conduct a pressure transfer experiment using our demonstration machine. We will share part of the results. 2. Pressure Rupture Experiment of Jacket Containers Jacket containers are stainless steel containers that allow for temperature control. However, there are times when customers mistakenly apply pressure to the jacket container, leading to its rupture. Such ruptures can result in injuries to operators and significant accidents due to the splattering of the liquid inside. We conducted an experiment to determine how dangerous it is when pressure is applied to a jacket container. 3. Transferring High Viscosity Liquids Without Spillage "Do anti-drip beakers prevent any liquid from dripping?" High viscosity liquids take time to clean up when spilled. When dealing with hazardous liquids, it is even more crucial to prevent drips. In this experiment, we used our anti-drip beaker to transfer a high viscosity liquid. Can we successfully transfer the high viscosity liquid without spilling it around?

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.

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.

One of the metal surface treatment methods, buff polishing, explained by a stainless steel container manufacturer!

The surface of the beautiful stainless steel container reflects like a mirror. Did you know that this beauty is not a characteristic of the material itself, but rather something artificially created? Generally, the surface of stainless steel containers is polished to a shine by a method called buff polishing, done by human hands. Here, we summarize a type of polishing method used to finish the surface of stainless steel, known as buff polishing.

● 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.
