Nakajima Overseas acts as the Japan Liason Office of Yuen Tai Hong Kong
Ltd. My relation with this company continues more than twenty years. This
is the trading company in Hong Kong whose owner has a factory in China
which has its long history of sewing machine parts manufacturing for more
than eighty years. The facility is located in Dongguang next door to
Shinzeng. Having reliable Lost Wax , Die casting and Forging subcontractors
owned by Taiwanese and Hong Kong businesses also its own heat treatment,
machining center, electric discharging, wire cutting and pressing machines,
they boast of their quality based on their own processing technology of
molds, pressing and finishing, which are far from the image you used to
have against the products made in China. Japanese and American manufacturers
of Knit Sewing or Over Lock Sewing Machines are satisfied with the parts
we supply. Also the factory has sufficient ablity to achieve high precision
machining which satisfies the customers in Japanese high technology businesses.
We do not have any regular parts catalogue. Our main business is supplying
the assembly parts to each industrial sewing machine manufacturer. We do
not supply generic parts in the market. The assortment of the parts we
are dealing is in so wide range that we, in frankly speaking, cannot accept
small lot size order such as ten to several dozen pieces. We need the order
quantity guaranteed with the number at least one thousand pieces per year
and we supply the quantity in a year deviding into several shipments.
Usually we receive inquiry with drawings by e-mail. At the same time
we ask some samples which is very helpful to know what kind of material
should be used and how extent of finishing level is required. We can assure
you more quick and accurate quotation if we have some samples. The
above is the explanation what Nakajima does for domestic (Japaense) businesses.
To the customers outside Japan we can supply parts from Japan, Hong Kong
and in China depend on the condition.
If you seriously want to begin transaction with us and need any engineering

less distortion is required in the process. Vickers and Rockwell Hardness
