UJEN – One-Stop Integrated Manufacturing

n today’s fast-paced market where product development cycles are tightening and supply chains are becoming increasingly complex, reliable and efficient integrated manufacturing is key to achieving speed-to-market and competitive advantage.
UJEN specializes in product design and mold development. Through a single point of contact, we integrate critical steps including design, mold making, material selection, forming processes, and surface finishing into a controllable and traceable workflow. This approach helps clients shorten lead times from project initiation to mass production, while maintaining consistent quality and cost efficiency.


Core Values of Our Integrated Service

* Leading product design and mold development: UJEN operates its own R&D and tooling center, overseeing every step from concept design and DFM (Design for Manufacturability) to mold trials, ensuring high-volume efficiency and component precision.

* Single-window project management: Our dedicated project managers handle timeline control and communication across suppliers, reducing risks due to miscommunication and blurred accountability.

* Optimized development schedule: Simultaneous mold design and prototyping cut early-stage project time by over 40% on average.

* Flexible production capacity: We support everything from one functional prototype to production runs of up to 100,000 units, with agile capacity scaling.

* Full-process quality control: In accordance with ISO 9001 standards, we use automated visual inspection systems to ensure consistency in dimensions, tolerances, and appearance.

* Cross-industry compliance: Our processes and materials meet the standards of medical, outdoor, sports, and electromechanical sectors.

* Sustainable material options: We provide PCR recycled plastics and other eco-friendly material alternatives to help clients reduce carbon emissions and meet ESG goals.

One-Stop Workflow Overview

* Concept design and DFM: Through 3D modeling, mechanical validation, and reverse engineering, we help clients quickly convert concepts into production-ready solutions.

* Mold development: Includes mold design, CNC milling, EDM processing, mold testing, and refinement.

* Material selection: Covers engineering plastics, PCR recycled plastics, elastomers, fiber-reinforced plastics, zinc-aluminum alloys, high-strength forged aluminum, carbon steel, stainless steel, tool steel, and more.

* Forming processes: Includes plastic injection, die casting, forging, CNC turn-mill, and stamping.

* Surface finishing: Capabilities include sandblasting, anodizing, heat treatment, zinc plating, electroless nickel, e-coating, painting, passivation, and rust prevention.

* Precision marking: Laser engraving, pad printing, and silk screening.

* Assembly and testing: Functional testing, strength and fatigue testing, fixture-based inspection.

* Packaging and logistics: Customized packaging and global shipping by air or sea.
