A factory specializing in injection molds, Tsushima Co., Ltd. This time, we asked about the benefits of working with a factory in China. Mr. Tachibana: At present, the cooperation with China is working very well, and we are receiving stable parts. In China, the “nesting” part of the mold's production parts is manufactured. In Japan, the base part called the “mold base”, which is the base for the nesting, is manufactured. Insert the insert into the mold base, match it, and check the area. At this time, if there is a gap, the resin will flow into the gap and it will not become a product. However, in China, we have matched with the nesting unit alone, so we have not made any major corrections so far ... By placing this nesting in China, it will be quick and accurate. Of course, costs can be reduced compared to outsourcing in Japan. China has much better technology than Japan in terms of machining, which is of course faster and more accurate. Unless you make a mistake in the design, the finish will be 5 / 1000mm. This is an amazing number. Since it is shipped to Japan after being inspected with a CMM, its accuracy is very good. Since there is no measuring instrument in the company, the machine accuracy is inevitably processed. Considering these aspects, if the cooperation with China is good, we can deliver to customers quickly from Tsushima, and we believe that there are only benefits for customers. -Thank you very much! After editing, it was a selfish image of the writer, but it was already old. I was impressed by Mr. Tsushima, who started to cooperate with overseas companies and is trying to differentiate himself from other companies.
