We would like to introduce the technical information "Microfabrication Technology News" for research and development designers.

Since its establishment in 1970, Goto Seiki has cultivated cutting processing technology, particularly in the field of optical and measuring instruments, where high precision and shape requirements are essential. This has become the foundational technology for Goto Seiki in precision parts manufacturing. In the realm of development and prototyping that supports the forefront of manufacturing, this advanced cutting technology is indispensable. Additionally, we continue to evolve as a versatile group aiming for optimization in precision parts processing using non-ferrous metals and resins, as well as in microfabrication and mold technology. In the technical information magazine "Microfabrication Technology News Vol. 6," we will introduce this month's column, methods for addressing shrinkage rates in prototype molds, and approaches for dealing with undercuts through segmentation. [Contents] - This month's column by Goto Seiki employees → Goto Seiki's efforts in processing coaxiality of φ0.01 - Methods for addressing shrinkage rates in prototype molds - Approaches for dealing with undercuts through segmentation and the benefits of cost reduction For more details, please contact us or download the catalog.

basic information

[Content] [Employee's Column for This Month] ○ Goto Seiki's Approach to Machining with a Coaxiality of φ0.01 ○ At Goto Seiki, we leave machining allowances on precision parts to allow for positional adjustments. After forming, we measure both the formed product and the mold, taking the adjustment values into account for reprocessing. [Methods for Addressing Shrinkage Rates in Prototype Molds] ○ We prepare test molds for shrinkage rate verification and conduct pre-forming to confirm rates down to 0.01%. ○ We never overlook appearance. ○ Goto Seiki conducts prior checks, resolves issues, and designs molds accordingly. [Methods for Addressing Undercuts through Division and Benefits of Cost Reduction] ○ We assess the magnitude and direction of loads on components and propose division methods tailored to the application. ○ Precision is also crucial for the positioning of divided parts, so we carefully consider the installation of fitting bosses and holes, as well as simultaneous machining of precision and positioning parts, and provide our suggestions. ● For more details, please contact us or download the catalog.
