Business outline

Saitama Planer Industrial was founded in 1961 as a metal processing specialist to finish casting in "Casting Town" Kawaguchi-shi, Saitama.

Our history of metal processing started from planer processing of SS400, S45C, which is the fundamentals of cutting, and has now expanded our range of processing to metals such as Hastelloy, Inconel, SUS304, etc. by double column machining center.

Our forte is precise machining for large parts, semiconductor production equipment parts, etc.Although heat resistant alloys such as Hastelloy, Inconel, and SUS304 in particular, are famous for hard-to-cut materials, we have accumulated many achievements with years of experience.

■ Machine polishing tools After machining a metal surface on NC machine tools such as machining centers, etc., using tools including ball-end mills, etc. to a specific shape, we achieved a mirror-finish (surface roughness within a Ra 50nm) in one go with one chuck by using a machine polishing tool affixed with a special rubber bonded grind stone (hybrid rubbing). Due to an up/down damper function and circular damper function, the point of the grind stone is able to follow the contours of the work, making it possible to polish flat surfaces, free-form 3D surfaces, vertical walls off metal dies, etc.

Business outline

～We can produce pipes and tubes of any shape and material, and can accept orders for just one!～Since established in 1960, we have been an electrode manufacturer over 50 years specializing in thin metallic pipes and tubes for machining fine-hole electric discharge. Our specialty is producing metallic pipes and tubes which are called capillary pipes and tubes with a diameter of 1mm or less. We produce every kind of thin metallic pipes and tubes using metals ranging from general purpose metals such as copper, brass, and stainless steel to difficult-processing materials such as titanium (alloy), cobalt-chromium alloy and up to precious metals such as platinum and gold.We are known by clients as a trusted helper; when they need help, KAKOH is always there for them, thus we have overcome various difficulties. Today, the result has led to our products used in almost all business industries such as aircraft, automobile, heavy industries, semiconductor, medical, energy, jewelry, sports goods, stationary, and cosmetics. In recent years we have displayed our products at domestic and overseas exhibitions with many visitors astonished with our products, asking "what on earth are they?" or "is this possible?" This has led to our company receiving many new proposals. We have provided several products which are the worlds' first or the world's smallest in the market. This is a result of our sincere responses to clients' "difficulties," and we will keep doing our best to resolve clients' difficulties in future.

■ Cylinders for pneumatic systems ■ Parts made by clad drawing ■ High-precision alumite

Drawing of irregular-shaped materials with fins is an original technology of Nihon Shinkan. We offer a cost benefits manufacturing method by eliminating post-processes such as inner diameter cutting and grinding.

This is a technology to join aluminum and other metals by a drawing process. It is often used for structural members of vehicles and heat exchangers.

This technology enables us to produce a uniform coated layer on the surface of expanded materials and die-cast materials. Unevenness of the surface is minimized so that the dimension control can be stabilized and corrosion resistance is enhanced.

Business outline

We manufacture power supply units, the core of electronics. Our main fields are design, development/manufacturing, and sales of industrial DC power supply and high precision-high-voltage DC power supply applying switching regulator at high frequency, and applied products of DC-DC converters, analogue/digital hybrid ICs, and microcomputers. We are now proposing new solutions of contactless power feed system, highly-efficient LLC circuits, DC power feed system, remote monitoring system, and semi-custom full digital power supply as keywords to meet recent down-sizing and diversifying trend of power supply for electronic devices. In the development of high-speed POL (Point of Load), we developed new control method with combining PWM (pulse with modulation control) control and hysteresis control. This achieves down-sizing by our own circuits and know-how and will be the optimum for high-density mounting. Noise level is 10mVpp (typ), the smallest in the industry and attains performance required in the times of large current at low-voltage for semiconductors. In the field of contactless power feed system which is growing significantly in recent years, we have established contactless power feed technologies using electromagnetic induction type, patent pending in collaboration with Saitama University. This provides various merits such as high convenience for the contactless power feed system, strength around water section for non-exposure of electrode, little degradation due to friction for contactless and enables us to propose the solutions with the high added value.
