上信樹脂 Company Overview

Leave the plastic molding of small precision parts to us.

Our company offers a unique and innovative small component prototyping technology called "Precision Injection-molded Prototyping." This technology allows for the prototyping of products using the injection molding method, which differs from traditional machining, thermosetting methods, or vacuum casting. It enables the production of prototype parts in the same material and precision as the final product in the required quantities within a short period (approximately 7 to 10 days). Additionally, we implement thorough quality control at all stages, including a final inspection of all units before shipment, ensuring zero defects upon delivery. Please feel free to contact us if you have any inquiries.
