Turning "it can't be made" into "let's find a way." Product development support, starting with what you have and where you need help.
Need to improve one part, restart a stalled development project, or turn an idea into something tangible? Fujikawa Jushi's "Saisei Sekkei" helps move product development forward by building on what you already have and focusing on the parts or stages that need attention. We start with existing parts, drawings, 3D data, prototypes or hand-drawn sketches, then reconsider the shape, structure, materials and manufacturing process. You can commission design changes, prototyping or manufacturing feasibility studies without outsourcing the entire project. Our strength is persistence: when one approach proves difficult, we explore alternatives. We combine hands-on injection molding experience with creative ideas to propose practical ways forward, with manufacturing in mind. Depending on your objectives, quantity and schedule, we consider methods such as 3D visualization, 3D printing, resin tooling, machining and injection molding. You do not need to choose a manufacturing method before contacting us. We listen carefully, even when your ideas are not yet fully defined. Tell us what is holding you back and what you want to achieve. We agree on the scope, deliverables, fees and schedule before work begins.

basic information
APPLICATIONS Improving part of an existing product Reducing size or weight, or consolidating parts Restarting stalled development projects Exploring replacements for unavailable parts Turning initial ideas into designs and prototypes SERVICE SCOPE Product design, structural design, 3D data creation and modification, prototyping, small-batch production using resin tooling, mold procurement and injection molding. We combine the stages needed for your project. REVIEW AND INFORMATION SHARING We use MViEW to share 3D models, along with physical prototypes where appropriate, to review shape, structure and intended use together. STARTING MATERIALS Existing parts, photographs, drawings, 3D data, prototypes or hand-drawn sketches. Complete documentation or specifications are not required for an initial inquiry. PROCESS We discuss your needs and agree on the scope, deliverables, fees and schedule before starting. Design-only and prototype-only projects are welcome.
Price information
Quoted individually based on scope, deliverables, quantity and testing needs. Design, prototyping and technical studies are paid services. There is no charge for an initial inquiry. Work begins after you approve the fees and scope.
Delivery Time
※Lead time depends on the scope, available data, quantity and review stages. Please tell us your target date. We will confirm the schedule before work begins.
Applications/Examples of results
PROJECT EXAMPLES ■ Station service robot housing Revised wall thickness and internal structures and consolidated parts while preserving the exterior design. Prototyping and review supported improvements in strength. ■ Solar car promotional miniature With only two months remaining before delivery, coordinated 3D data creation, prototyping, mold making, molding, printing and assembly to meet the deadline. ■ Tape holder for a discontinued product Designed a compact, thin-walled holder in response to a request concerning discontinued DYMO tape and supported the transition to production. TYPICAL APPLICATIONS Improving existing plastic products Reviewing strength, size, weight and ease of assembly Restarting development from existing drawings or prototypes Exploring replacement parts when originals are unavailable Turning sketches and initial ideas into designs and prototypes Planning small-batch production and the transition to volume manufacturing Please tell us what you have, what you need to change and what you want to achieve.

Company information
Need to improve one part, restart a stalled development project, or turn an idea into something tangible? Fujikawa Jushi and its Magical Heart division combine hands-on manufacturing experience with creative ideas to help you move forward. Our approach, "Saisei Sekkei," starts with what you already have: existing parts, drawings, 3D data, prototypes or initial ideas. We rethink the shape, structure, materials and manufacturing process, focusing on the parts or stages that need attention. You can commission design changes, prototyping or process planning without outsourcing the entire project. When one approach proves difficult, we explore alternatives. We listen carefully, even when your ideas are not yet fully defined, and work with you to find a practical next step. Our services include product design, 3D engineering, polycarbonate 3D printing, resin tooling, small-batch production and injection molding. We also use MViEW for 3D model sharing, alongside CGI, animation and virtual exhibitions, to help people evaluate and communicate products and ideas. We provide paid technical consultation, injection molding training and practical AI adoption support based on our own business experience. The scope and fees are agreed before work begins. You do not need complete drawings or specifications to contact us. Tell us what you have and what you want to achieve. Online meetings and non-disclosure agreements are available.
