KOBAYASHI TOOL MFG’s Tool Manufacturing Technology

From manufacturing tools, such as offset wrenches and other work tools, electric cutting tools such as offset wrenchs and various industrial edged tools to machine parts, we provide development, design, manufacturing, inspection and packaging services of all OEM products. As well, import and export options are also available.
OEM orders can be made to order.
Our customer’s needs are catered to as much as possible including matters of short delivery, cost reduction, small orders etc.

Also, based on drawings received from cliants, we provide prototype development and production services.
There are merits to this such as shortening the development period of the prototyping process, the planning process of new products, trial production processing at the research stage and mass production processing and prototyping in anticipation of mass production with strict confidentiality during development.
Using our one-stop production manufacturing system, from trial manufacturing to mass production and assembly, we have become experts at manufacturing products, considering manufacturing processes, and the work required during mass production.
We can consistently assemble composite parts, flexibly support assembly, packing, and shipping the final product as per your specific requests.
In addition to ordinary product packaging, we assemble and pack the final product as specified by the manufacturer.
Bundled work such as assembly of the final product, a check of neccesary accessory parts, instruction manuals and more are flexibly adapted per the cliant’s request.
For cliants and manufacturers, we contribute greatly to securing optimum stock and shipping in Just In Time.

Hot forging achieves overwhelming durability. More so than other manufacturing methods.

It is almost impossible for other companies to manufacture thin blades using a forging process. We have realized this by utilizing technology specific to KOBAYASHI TOOL MFG. Unlike products from other manufacturing methods, please expect excellent durability unique to our forging process.

The microphotographs (50x magnification) below show the comparison of the endurance test result ( 500 times cutting test of 325 sq.-mm copper wires) among; (a) A Forged cutter (KOBAYASHI TOOL MFG product), (b) Lost wax molded cutter (Product of Taiwan) (c) Blanking machined cutter (made from plate material) (Product of China)

(a) Forged blade (KOBAYASHI TOOL MFG product)

The brighter white area along the edge of the blade after the test reveals that the original black surface finish (corrosion resistance) has been ground off.
The structure of the edge is completely maintained despite the strain of the cutting test. The sharpness of the blade is mostly maintained and is almost as sharp as it was before the test.

(b) Lost wax molded cutter (Product of Taiwan)

The edge (grinded part) is completely lost and broken. It is afraid that the service life might come to the end before long if continuing usage. The many ditches on the blade surface are scratch marks given by copper wire during the cutting test.

(c) Blanking Machined Cutter (Made from Plate Material) (Product of China)

500 times cutting testAfter a 500 times cutting test of 325 sq.-mm copper wires
By the 400th cut, this cutter had broken (that is, the handle springs had broken down). At this point, the test was discontinued. The photo shows the condition of the blade at this time. The edge (grinded area) is completely destroyed and broken. The possibility that the service life of this product might soon come to an end with continued is reason for concern. The many deep scratches on the blade surface are marks created by the copper wire during the cutting test.
