Miyoshi Co., Ltd.'s "Mold Manufacturing" provides a comprehensive in-house response from mold creation to molding. We fully support those who need a small quantity for evaluation tests or research, want to try out new materials under development, or are facing challenges with prototype molds and small lot production. Since we handle everything in-house, products that require frequent mold modifications or trial molding can be advanced quickly. In the unlikely event of a problem, we can investigate the cause and implement measures from both the mold and molding perspectives. 【Features】 ■ Molding can be done from a single piece ■ Supports sizes from 10mm square to A4 paper × 60mm thickness ■ Compatible with general-purpose thermoplastic resins and engineering plastics ■ Consultation available for quantity and cost, as well as gate, protrusion, and mold splitting discussions and defect predictions ■ Consultations are also possible for areas outside our expertise (3D printing, prototype production, printing, painting, etc.) *For more details, please refer to the PDF document or feel free to contact us.

At Miyoshi, we accept molding orders starting from a quantity of "1 piece." We address concerns related to small lot production, such as "the required quantity varies by month" and "there is a minimum order lot that must be met," by providing estimates for each quantity and delivering the necessary amount each month. Additionally, we also handle small quantities of various types, insert molding, and long-term storage of molds. As an internal record, the most common molding quantity per lot is approximately 100 to 1000 pieces. 【Features】 ■ Orders can be accepted from 1 piece ■ Specializes in small quantities of various types and insert molding ■ Capable of handling a wide range of products with 40t hard-type, 80t, and 230t horizontal injection molding machines ■ Product sizes typically range from 10mm square to A4 size × approximately 60mm ■ Long-term storage of molds is possible *For more details, please refer to the PDF document or feel free to contact us.
