"Do you have any concerns about the need to consider efforts to reduce environmental impact?" At our company, we have been engaged for many years in activities that contribute to reducing environmental impact, maintaining the precision of molded products, and lowering costs by crushing runner parts that do not become products and re-pelleting them (processing them back into pellet form) for recycling. Our overseas production subsidiaries are also undertaking similar initiatives, recycling approximately 340 tons of waste annually. We have a wealth of experience with molds equipped with hot runner systems that do not produce runners at all, and inquiries from customers have surged in recent years. *For more details, please refer to the related links or feel free to contact us.*

The precision processing technology of the Sanshu Group combines ultra-precision mold manufacturing capable of creating shapes and irregularities at the nanometer level, with resin molding technology that achieves a transfer rate close to 100%. It is generally said that fine processing of resin is very difficult, but our company combines two technologies to enable the production of complex holograms and lenses with a magnification of three times. In recent years, there has been a growing demand for product "lightweighting" and "miniaturization" across various industries, leading to a shift from metal to resin. However, in the field of fine processing and molding of resin, the high level of difficulty means that there are not many companies capable of handling it. Our precision processing technology has a proven track record of solving the challenges mentioned above. If you are interested in or considering precision mold manufacturing or fine resin molding technology, please feel free to contact us. *For more details, please refer to the PDF materials or feel free to inquire.
