成長ポテンシャル - 株式会社カワタTarget of processing of all powders and granules
In its long history, Kawata has continued to grow by constantly reading the needs of customers and developing products that meet the demands of the times.
Until now, the place of activity was mainly plastic processing site.
However, while maintaining the position of Soseki in the traditional plastic-related fields, it has started to expand into fields other than plastics by applying the technologies acquired so far.
A case
case 01 Field of leaping liquid crystal materials
With the transition of TV analog broadcasting to digital broadcasting in July 2011, domestic shipments of LCD TVs roughly 2.5 million in 2005, 4.7 million in 2006, 7.1 million in 2007, 840 in 2008 We are growing dramatically with 10,000 units.
Although there is a decelerating trend from the latter half of 2008 to the first half of 2009, due to the impact of the energy-saving home appliances eco point system implemented from May, a smooth trend is expected, and stable demand is expected until 2013 after the transition of digital broadcasting It is thought that it will continue.
The surface of the liquid crystal TV is laminated through processes such as film formation or lamination of multiple layers such as high function film and glass substrate with various functions.
When processing each layer using a roll machine (a machine that processes thin sheets), advanced temperature control is necessary to ensure accuracy, strength, and transparency, and Kawata's heat medium circulation Temperature Controller is used in the field of liquid crystal materials. Widely used.
case 02 Magnetic material field with unlimited possibilities
Powerful magnets installed in hard disk drives, CD players, mobile phones, etc.
Magnets with even higher functionality and performance are essential for next-generation means of transportation such as linear motor cars, as well as hybrid and electric vehicles whose demand is expected to increase in the future. The coercive force of these high-output motor magnets is increased by adding rare earth elements such as neodymium (Nd) and dysprosium (Dy).
Kawata's super mixer is widely used in Mixing process of all kinds of magnetic materials due to its fluid Mixing technology, which is a condensation of original ideas, and we expect it to continue to be used in the future.
case 03 Kawata's technology also applies to lithium-ion batteries used in hybrid cars
Compared to nickel · cadmium (Ni - Cd) batteries and nickel - hydrogen (NiMH) batteries which are other miniature secondary batteries, lithium - ion secondary batteries (batteries that can be repeatedly charged), which are drawing attention as high - capacity batteries, Due to its light weight and compactness with the same electric capacity, it is used as a power source for most portable devices, mainly laptop computers and mobile phones, and demand is rapidly expanding rapidly as a battery for hybrid cars recently.
Batteries generate electricity when ions generated at the negative electrode move to the positive electrode. When charging, ions can move in the opposite direction, so that it can be used repeatedly.
Lithium cobalt oxide is commonly used as the material for the positive electrode (positive electrode material), and Kawata's dry Mixing technology using Mixing (super mixer) has been highly praised.
In addition, a microporous membrane called a separator made of polyethylene (ultra-high molecular weight PE) or polypropylene (PP) is used between the positive electrode material and the negative electrode material to prevent short circuits caused by contact between the two electrode materials and to retain the electrolyte. It plays the role of ensuring conductivity. The manufacturing process of this separator also utilizes a raw material Conveying, drying and supply system based on clean technology established in the optical disc field, which is Kawata's area of expertise. Kawata's technology is being used in a variety of applications at a time of transition when the industrial structure is changing.
Support the new era
Challenge to material technology
Throughout history Kawata has always contributed to labor saving in the processing of materials to open up a new era. Such frontier spirit of Kawata is still being handed over unchanged today.
A good example is "efforts on new energy materials". Kawata's main battlefield is plastics that is made from fossil fuel as a raw material, but Kawata is proactively entering the field that supports future world energy demand besides such fossil fuel.
