Parts processing, procurement

From a design design of various parts processing to procurement, quality control, leave it to me all

I solve a trouble about various parts processing in the Koshin business and industry around Tokyo, Kanagawa around three Tama.
Which "I do not know where I should ask for this processing" contributes to "is there not the supplier who can cope by a short deadline, reduction in cost?" and having a problem.
Of industrial equipment, an FA device, the facilities machine
Article, die parts including a chikogu, repair product, a group, processing, procurement management, quality control
As for all this, leave it to me! Even from one piece of article, I produce it!

Our three characteristics

When suppliers extend over the plural number, need to take the cooperation by each process occurs, and lead time hangs. On the other hand, I can realize reduction in a man-hour, lead time than Koshin business and industry exchange you with plural processors because we exchange lumps with a processor.
In cases such as the product defectiveness of the emergency, the risk of the product guarantee occurs without having only each part which I undertook guarantee it when I break up a multi-process to various suppliers and place an order outside. On the other hand, we exchange Koshin business and industry with the parts processor with the results as procurement representation and, in the case of the product defectiveness of the emergency, can cope quickly.
In the Koshin business and industry, I accepted an order of various parts processing led by government offices, the public institution for many years. I make use of these know-how and there is not request and copes with the parts production that is not appreciated flexibly!

The guarantee of quality system of the relief

1. Inspection results book
・Examination for appearance
・Special inspection of the trial product/height of the rise product
・Inspection before acceptance/shipment such as overseas import goods
・Examination with precision parts using a magnifying glass, a microscope
・Modified work such as rust/Bali adhesion
・Incidental work such as inspection and the packing that I combined with it
2. The abundant measurement, inspection equipment
3. The trouble correspondence is fastest, and it is carried out
4. Domestic quality
5. Quality for university, research organizations
There are the results that delivered the majority to laboratory of seamanship or JAXA so far in us, and there is absolute confidence in quality. At first please consult about the person who is anxious about quality once.
