Founded in 1954, Sansyu Precision has taken Takahama City as its base to produce and supply the precision plastic parts and metal processed parts for all fields for half a century. Sansyu develops its unique technologies including ultra small precision molding technology, ultra-thin wall molding technology and overmolding technology of dissimilar materials, and constantly provide a large variety of indispensible precision parts from the parts of ink printer, copying machine and other OA equipments, to automotive interior switch/button, digital camera, bearing and medical appliances, etc.
Sansyu Group’s strength is "precision". You would be surprised by the precision of our tiny plastic parts that can be only seen through a microscope. To realize such a precision depends on all kinds of technologies developed by us for half a century. We, as a pioneer in the production of precision plastic products, take pride in our high technologies incomparable by other companies.
Industrial products are constantly miniaturizing. In the past, our corporation devoted itself to the production of pointers and stems in watches. Since our founding, we have been improving the "precision" of the parts we produced, and developed the unique technologies including "ultra small precision molding technology", "ultra-thin wall molding technology" and "overmolding technology of dissimilar materials", etc. As a leading manufacturer in the world, we manufacture precision plastic products to firmly support small products.
The "ultra small precision molding technology" is a technology to produce the moldings with the outer diameter of below 1mm or the moldings with a lot of 0.2mm holes. This technology has been applied in producing the 0.6mm PC bobbin and the ultra thin brush precision molding with the projected head diameter of only 0.1mm, etc. The "ultra-thin wall molding technology" is a technology used to produce below 0.1mm thick moldings and often applied in the production of parts for copying machine, etc.
The "overmolding technology of dissimilar materials" to combine two different materials in a mold can manufacture two parts that are originally produced separately at one time, so it gets much attention. We have made great achievements in the combinations with translucent resin, soft resin called elastomer, development and mass production of precision moldings, etc. Among them, our market share of automotive interior switch becomes larger and larger.
