We support our customers' product development prototypes with our accumulated know-how.
●Simple molds ●Prototype molds ☆We respond to requests for "molded products as soon as possible." ☆Our company specializes in short lead times for small-scale production and supports the development and design of products and parts. ☆From the start of mold construction to the first molding prototype trial, our in-house specialists manufacture and process quickly. ☆Based on the accumulated know-how in plastic molding, we provide useful proposals. ☆We have extensive experience in three-color molding, two-color molding, insert molding, and ultra-precision injection molds. ●Integrated Production Our company manufactures most molds in-house, allowing us to conduct test molding immediately after mold completion. Additionally, if any issues arise during test molding, we have the capability to quickly make corrections (modifications) after reporting to the customer, thereby reducing the time and cost until good products can be processed. ●Production System Our company has a flexible production system specialized in manufacturing small quantities (small lots) of parts with short lead times, achieving high cost performance. *For more details, please refer to the PDF materials or feel free to contact us.

Applications/Examples of results
Automotive electrical components, motor parts, building material components, camera parts, printer parts, etc. ● Simple molds ● Prototype molds ● Reduction of man-hours In the case of mass-produced molded products, production systems are typically organized to minimize the number of setups for injection molding machines. Therefore, in small-lot production, the number of setups increases, leading to inefficiencies and higher costs. Our company utilizes a dedicated mold base developed in-house to create a specific configuration suitable for small-lot prototypes, processing molds with machinery that has the appropriate performance and specifications, and minimizing the number of setups for injection molding machines, while managing the production system of molded products as needed. These efforts enable us to maintain a certain level of processing efficiency, which leads to reduced manufacturing costs and significant benefits for our customers. ● Quick response Especially in the case of prototypes, design changes may occur frequently. Our company leverages the strength of having an in-house team of mold design engineers to quickly assess whether we can accommodate design changes or requests from customers by modifying the molds. If changes are possible, we can of course promptly reflect the requests in the molds.
