Essential for factory automation! All about Customizing Stainless Steel Containers

In recent years, the trend toward automation (robotization/factory automation) has accelerated in pharmaceutical and cosmetics factories. In NITTO KINZOKU KOGYO, customers who want to use stainless steel containers in automated production lines are increasing rapidly, especially the requests of custom-made containers.

By customizing the stainless steel container according to the equipment and work to be used, you can take full advantage of the equipment's performance and solve process problems.

In this column, we introduce customizations and products recommended for stainless steel containers to be introduced into the automation process.

How to Make Stainless Steel Containers "Easy to Handle" in the Automation Process?

To match the size of your needs

NITTO KINZOKU's containers can be manufactured with a size that matches your work allowable size, storage space, input amount, etc. Our company works primarily with customizing height dimensions.

We can also customize the inner diameter of the container, but basically, we have to choose from the following sizes. We can also make the container of the original diameter if you would like to bear the corresponding cost such as making the mold from scratch.

Inner Diameter of our company Standard Lineup (mm)

180/210/240/270/300/330/360/387/430/470/565/635/770/1000

*Other sizes may be available. 

* The available sizes may also be limited depending on the container specifications.

To avoid interference

For example, you can customize the mounting position when the handle on the container interferes. If you don't need the handle itself, you can choose “No Handle”.

To make it easy holding

When there is a lifting action

 

If you have an action like “ to lift the container and put it on a different pallet ”, you might want to customize it by attaching a bracket to the side of the container. The bracket can be designed to meet the specifications of the robot, so it can be held securely.

If there is no interference or other problems, you can install both a handle for people and a robot bracket.

* The handles on ordinary containers are designed to be handled by human hands and are not intended for use in robots or lifters.

When there is a grasping motion

If you have needs like “grab and flip ” handling action, you might want to customize it by machining ribs on the sides of the container. By processing the width and position of the rib according to the width of the arm and claw on the grip side, it is hard to shift and can be firmly grasped. Ribs also have the effect of increasing the strength of the container side.

The jacket can be attached to the outer surface of the container to customize the size to match the robot hand chuck.

Enhance the Stability

If the contents are heavy, the bottom of the container may swell outward, causing the container to shake and become unstable when placed or transported on a conveyor. In this case, customizing the bottom is recommended. For example, if you attach a “Skirt” to the lower part of the container, the bottom will not touch the conveyor and stability will be improved.

It can also be customized to reinforce the bottom by attaching a plate that matches the diameter of the bottom to the outside of the bottom. The bottom is hard to deform and stability is improved. It is also possible to raise the thickness of the container itself without using a reinforcing plate.

You can also customize the bottom by embossing it to increase its strength of the bottom. In addition to increasing the strength of the bottom to prevent it from bulging, the center of the bottom, which tends to bulge, does not come in contact with the conveyor, which improves the stability.

For Easy-Opening

Open by Just Lifting the Lid


If the lid is easy to open and close, it will be easy to be automated. It is recommended to customize the container based on a cover type container, rather than an airtight container with parts to fix the lid. The cover can also be customized with a handle or bracket that matches the robot hand.

Just turn the cap to open it!


If rotating (twisting) motion is possible, a container with a screw cap is recommended. Screws are mainly used in small-capacity bottles. It is also airtight compared to a cap lid.

How to Make Stainless Steel Containers "Easy to Wash" in an Automated Process?

Improve the cleanability of the inner surface of the container

It is recommended to apply electrolytic polishing to the inner surface of the container which directly touches the contents so that it does not get dirty easily. By electrolytic polishing, the inner surface of the container, the residue on the surface is removed and the surface becomes smooth, preventing dirt from sticking.

If you are handling highly viscous liquids, we recommend you to apply fluorine resin coating. It has features such as non-stickiness, which prevents most substances from sticking, and water repellency, which repels water and oil, and can remove dirt quickly.

Improve the washability of the outer surface of the container

There are many parts on the outer surface of the container, and it is a place where unevenness occurs after washing. The parts where dirt and cleaning solution are likely to remain can be customized in consideration of cleanability. Our company can propose sanitary specifications that are superior in cleanability.

For example, we recommend customizing the edge of the container with a curl seal (fully circumferential welding) that completely closes the gap. 

For the handle, we recommend a round bar handle (sanitary type) that can be sealed by welding all the mounting parts.

How to Make Stainless Steel Containers "Manageable" in the Automation Process?

Adding Laser Mark to the Container

Laser-marking is recommended because it is a printing method that does not peel off and does not disappear even after washing, and also prevents tampering. The original control number or QR code can be printed on the side of the container or on the lid.

Add a label pad

It is recommended to add a seal seat which is easy to peel off the label when the label is reattached after managing with bar code labels.

Add a card holder

If you use a paper card, we recommend adding a card holder to prevent it from getting wet and dirty.

Management with RFID
When managed by RFID, the container can be managed by attaching an RF tag. You can customize the container according to how the RF tag is installed.

3 Concerns about Sterilization of Stainless Steel Products

3 Concerns about Sterilization of Stainless Steel Products

Sterilization of clean containers is important in the manufacture and storage of cannabis and CBD products.

Stainless steel can be sterilized, but some stainless steel products can and cannot be sterilized.

Although there are various types of sterilization, this time we will introduce the case of sterilizing a stainless steel container (SUS 304/SUS 316 L) manufactured by Nitto Metal Industry by autoclaving (autoclave sterilization/121 °C for 20 minutes).

Please feel free to inquire about the sterilization of each product.

Can stainless steel products be sterilized?

As long as the product is made of all stainless steel (made of only stainless steel) and has no parts such as resin or rubber attached, sterilization in an autoclave is basically possible.

Do you have an image that stainless steel products are used in hospitals and laboratories?

Examples of Stainless Steel Products Requiring Confirmation of Sterilization

・Be equipped with resin components
・Comes with rubber parts such as packing
・have casters
・Be labeled

In such products, even though the stainless steel part can be sterilized, there is a possibility that the attached parts cannot be sterilized (for example, the heat resistant temperature of the parts is too low to be sterilized), so it is necessary to check beforehand.

Check the heat resistance of the product or contact our company.

The silicon packing ([PQA] [PQB] [PQL]) that comes with the standard our company stainless steel sealed container can be sterilized by steam.

Check the heat resistance of the product or contact our company.

What should I be careful about sterilizing stainless steel products?

・Remove parts that cannot be sterilized

・Remove the parts that can be removed so that it can be sterilized to every corner.

・Keep the container open (with the lid open) and put it in the sterilizer.

・Put small parts such as tools in a basket.

・Dry well after sterilization

Refer to the instructions for using your sterilizer.

Sterilize stainless steel products so they don't rust?

Stainless steel is not rustproof, but it is a rustproof metal, and it will rust if the rust condition is satisfied.

For example, if water droplets remain after sterilization, they may rust and become rusty in the same way as normal cleaning. Therefore, please dry thoroughly after sterilization.

Stainless steel products that are highly recommended if sterilization is a prerequisite

Stainless steel products that do not easily collect water droplets and allow smooth drying after sterilization

There is a stainless steel product with improved sanitary property by eliminating the part where dirt and water accumulate.

Since there is no part where water enters the product body, it not only dries smoothly after sterilization, but also has excellent washability and can be used to prevent contamination and contamination.

Stainless Steel Trolley for Autoclave Sterilization

The standard container truck cannot be sterilized.

“KMS-A” is a sterilizable carriage with casters that can be sterilized in an autoclave.

Stainless Steel Products Supporting Sterilization

We also manufacture stainless steel sterilization cans and baskets that are useful for placing instruments in sterilization machines.

Can be custom-designed and manufactured according to the size of the sterilizer and the size of the instrument to be inserted.

It is possible to order “I want to prioritize the usability here”.

Our company's containers are particularly well received by Japanese pharmaceutical manufacturers. We have been supplying to generic pharmaceutical companies and health food manufacturers including Megapharma for many years.
In addition to considering applications and usage environments, we can design and manufacture stainless steel products that meet customer needs, such as “We want products that are suitable for sterilization” and “We want to place importance on measures against contamination.”.

Do you know the high grade material “SUS 316 L” of rust-resistant stainless steel?

It is important to maintain durability, light resistance, cleaning, and sterilization in the production and storage of cannabis-oriented products.

The stainless steel container is held in place by four equally spaced strong clamps, the underside of which is bordered by silicon. These combinations maintain airtightness and deodorization.

This time, we will introduce the details of the “material” of stainless steel containers that are used in pharmaceuticals and Cannabis plants.

We recommend it to people like this.

  • To prevent contamination with CBD oil
  • be looking for a product that puts safety first
  • Looking for products that focus on functionality and Cannabis quality over cost

Stainless steel is famous as a rust-resistant metal, but there are various kinds of stainless steel materials, and the strength of corrosion resistance is different. If you're looking for a stainless steel container that's more secure and functional than cheaper, this article should help.

What is rust-resistant stainless steel?

Generally, in the pharmaceutical industry and the food industry, the following materials are called high-grade stainless steel materials.

SUS316L

SUS 316L is a material that is more resistant to corrosion than ordinary stainless steel.

(The type of stainless steel is indicated in accordance with JIS standards. “SUS” represents stainless steel, followed by a number representing each steel type.)

One of the important factors in the quality of containers is "corrosion resistance."

If you store and store cannabis or CBD material, you need to avoid the risk of foreign material getting into it as much as possible, but if you use metal containers, the risk of “rusting” is always there.

If rust occurs, the following accidents could occur.

・Fragments of the rusted body get mixed into the content liquid and powder.

・Crackage or loss of rusted parts.

It is very important to avoid the risk of “rusting” and “corrosion”, especially in pharmaceutical and food manufacturing factories where high hygiene standards are needed.

Many stainless steel products, known as “rust-resistant,” are widely used in such fields.

Stainless steel containers can be stored appropriately while avoiding corrosion of the container body.

Different stainless steel materials have different performance of corrosion resistance

SUS 304 widely used worldwide

The stainless steel that we touch the most in our life is SUS 304.

The stainless steel material SUS 304 is said to be the most common type of steel and is used in a variety of places, including food equipment, general scientific equipment, building materials, the paper industry, the rolling stock industry, and kitchen equipment.

Our company also uses SUS 304 as a standard material.

SUS 316 with improved corrosion resistance

The material with higher corrosion resistance performance than SUS 304 is SUS 316.

There is a component called “molybdenum” which is not contained in SUS 304.

This molybdenum makes the passive film thicker and improves corrosion resistance.

Improved corrosion resistance in welding! High Grade Material SUS 316L

SUS316L is a material invented as an “updated version” of SUS316.

Metal has the property that while heat is applied during processing,  the metal material becomes easy to corrode and break.

SUS 316L is a low-carbon type stainless steel with a low carbon ratio contained in SUS 316. It is a material that is resistant to corrosion (intergranular corrosion) at the weld zone where parts are joined together.

SUS 316L is generally recognized as a high-grade model of stainless steel.

The quality of the cannabis is important, but it is also important to keep the high quality of the cannabis. Material selection is very important.

The following stainless steel container are made of SUS316L with excellent performance of corrosion resistance.

Nitto Kinzoku Kogyo can manufacture every container with SUS 316L material.

The container body can be changed to SUS 316 L material.
Most of the products on the product page are made of SUS 304, but it is possible to make them with SUS 316L material.
We will change the material of the body part where the liquid and powder you handle come into contact to SUS 316 L.
We also accept customized orders for products made by SUS 316 L materials. Please feel free to contact us.
