HIVIX – manufacturer of
high-frequency welded and
heat-welded plastic products





At Hivix, to solve the customer’s concerns about their products and capitalize on our advantages, we use the power of air and work together with the customer to generate proposals and develop products for market.
ometimes as we are involved at the planning stage, or when researching original materials, a ground-breaking idea may spring forth.

Product An air mat that when inflated retains a flat surface

For many years, Hivix produced air mats that include internal partitions made from substances such as PVC, to keep the swelling flat when the mats are inflated, however we weren’t able to achieve a totally flat surface with that structure. This was preying on my mind.
Although at the time our air mats were used mainly for swimming and things like that, we wanted to overcome the hurdle of achieving an air mat with a flat surface. WE wanted to make an air mat make one that could be used in various ways and that could satisfy highly demanding needs.
Then one day I attended an industrial fiber trade fair in Osaka. While there, I came up with the idea to replace the internal partitions with fibers stretched between the surfaces, to keep the surfaces flat. “This is it!” I thought. I was convinced that this was the solution to our problem.
It was love at first sight (laughs). We immediately began development of a new type of air mat using fiber.

I had the idea for a structure using fiber about 17 or 18 years ago and, starting with the development of the materials, it took about 4 or 5 years to develop a finished product.
From then on we attempted commercialization of the product in various forms, improving and refining little by little as we went. It must have taken about ten years all told before we finally settled on the current design. Developing something totally from scratch, everything from the materials to the techniques, as we did with High-board, takes an enormous amount of patience and perseverance.
At first we made mattresses for use in cars. We pitched the product to various dealers and car manufacturers. However, the cost of manufacturing the mattresses was really high and we were unable to achieve commercialization of the product.
After that we developed all sorts of product prototypes and various suggestions for their use, but in the end, due to the cost aspect, nobody was willing to take up our product. The days dragged on like this.
Although we had confidence that we’d developed a breakthrough product, due to the cost aspect we were unable to achieve commercialization. As the days of worry stretched on, we hit upon the idea of marketing High-board, not as a general product as such, but as a tool. We cast around and identified a need in the construction industry. That need was for concreting formwork.
Up until now, formwork in the construction industry has generally been made of polystyrene foam. Once the concrete has set, the polystyrene foam needs to be broken up and removed, a tedious and time-consuming job. However, if you use High-board instead, you have flat surfaces with improved strength, then, once the concrete is set, it’s a simple matter to release the air from the High-board and remove it, just like that. High-board has proved popular in the construction industry. It has finally seen the light of day and has become a product that we believe is worthy of commemoration.
Although one of our proposals for High-board had finally seen the light of day in the construction industry, we were still troubled by the fact that due to the cost aspect we were unable to successfully pitch it as a general product. While considering this problem, our thoughts turned to one of our very first products, the small inflatable pool.

Small inflatable pools were very popular at the time and were used widely in homes and kindergartens, but we thought that if we constructed a pool from High-board it would have very strong sides, sides that could be sat on without collapsing the shape, and so we set about developing a prototype. We eventually entered into a tie-up deal with a South Korean manufacturer and successfully completed the construction of a High-board pool.
To our great delight, this product has become a true long-seller; it is still being produced now over ten years later. It is very popular among kindergarten staff, who continue to use it even after many repairs.
From general product to civil engineering, from proposal after proposal, and then to finally end up back at one of original products, the small inflatable pool, is just staggering. We never expected such a thing, but never have we been so happy to be proved wrong!
Inflated air products have the potential to solve problems in any industry. From the smallest cues, we seek to create proposals and prototypes that address questions like “What kind of product could we use this material for?” or “What kind of problems in the industry can we bring solutions for?” Without the constant reiteration of this process, High-board would have remained nothing but a “strong but expensive air mat”; nothing would have come of it and the pool wouldn’t have been the hit that it was. The key to success in our work is less about giving birth to new things, and more about the strength of our ideas and proposals.
