Prototyping of plastic and aluminum is possible from one piece to small lots! A collection of case studies is also available.
We bring dreams and images to life with creativity and passion in plastic prototyping. We propose manufacturing methods tailored to meet our customers' needs.
With our 25 years of expertise and equipment, we carry out manufacturing tailored to our customers' needs through a production system that integrates analog and digital technologies. We can handle prototypes from a single piece to production, using materials ranging from plastic to aluminum and metal. 【3D Printing】 We can provide tailored modeling solutions through in-house and network capabilities, including FDM, resin printing, and powder printing. Our unique modeling methods allow for precise dimensional outputs. 【Machining】 We employ methods to manufacture three-dimensional products from processed materials with short lead times and high precision, capable of cutting sheets from a single piece. We can produce without molds and accommodate a wide range of materials from resin to aluminum. 【Vacuum Casting】 We create high-precision rubber molds based on actual items or master models, injecting polyurethane resin into these molds under vacuum to form products. We can meet user needs with short lead times, low costs, and high precision, and we excel in large-scale casting of one-meter-sized products using our unique technology. 【Simple Molds + Injection Molding】 We design and manufacture aluminum simple molds and handle the entire process of injection molding in-house. Using vertical molding machines and our standard base molds, we can achieve low-cost solutions through unique technologies like slide-less mechanisms. *For more details, please download the PDF or feel free to contact us.
