Examples of tube filling and grease filling

We know our product can be used easily in aluminum tubes, but where can we buy those tubes? How can we fill them with our product? - Many of our customers had these questions.

Customer needs

They wanted to put their 300 nail colors into retro-inspired aluminum tubes and release them as new products.

Customer's challenge

They searched for a manufacture that could put small amount of each color into aluminum tubes, and found us.

Our response

We first checked whether the product inside reacts with aluminum and degrades, and the degree of ultraviolet transmission with sample filling test before manufacturing 1,000 pieces of each color. Few manufactures offer aluminum tubes for non-industrial use, and they have minimum order quantity even if you are able to find one. Harves is able to propose some of our regular stock tubes in the size commonly used by many customers. Our 1g-3g small tubes and 5g-10g are among our specialties.

Our wall repair product has a variety of colors to match the wall of ordinary houses, but we do not know which one will sell the best until we actually launch it. Is it possible to release this hard-to-handle solvent in all colors and in small lots? - The customer wanted to see our filling process on site before making the decision.

Customer needs

They want to put the 200-color building repair agent that hardens with moisture in the air into easy-to-handle tac tubes while purging nitrogen, and release as new product.

Customer's challenge

The company only manufactured the product in bulk and was looking for a partner who can handle the filling for 200 pieces/color.

Our response

After selecting a filling machine, we conducted sample filling with the customer on site to check the details of manufacturing process. We now receive periodic orders mostly for the 50 popular colors. We checked the SDS in advance, and received their representatives from sales, product development, quality management and procurement divisions to confirm the filling machine and technologies. The expertise of the client and our proposal together resulted in a successful business.

If we put our grease into aluminum tubes, there is a risk of leaking due to liquidation under high temperature. Is there a way to test it in advance? - They wanted to conduct the test and confirm before commercialization.

Customer needs

As the product will be exported by ship, they wanted to check the durability under high temperature while going through the equatorial region.

Customer's challenge

They were looking for a filling company with regular stock of aluminum tubes and able to take orders in large quantity.

Our response

We conducted accelerated heat-proof test with assumed temperature of 100°C on the deck and 80°C inside the container ship. After selecting the tubes to be used, we started receiving constant orders. We put several greases with different properties into aluminum tubes and conducted a test using Arrhenius model for temperature acceleration. A variety of data was obtained on the property of grease, impact of the volume of the air inside the tubes, etc., before finalizing the specification. While laminated tubes are predominant in the market these days, many products are also released in aluminum tubes to highlight their convenience and rhetoric impression. It is especially good for high-value products in 1g-10g/package.
