Core Values and Quality Management System

At UJEN, our commitment to precision, reliability, and innovation forms the backbone of every fastening component we design. For nearly five decades, we’ve built our reputation on precision mold development and high-consistency manufacturing, empowering global brands with stable quality and predictable lead times.

Our core values—Unconventional Innovation, Just Right Design, Experimental Engineering, and New Sustainable Future—define how we approach every project, from early design consultation to full production. These four principles are more than ideals; they are our daily practice in delivering performance and aesthetic harmony in every handle screw, knob fastener, and clamping handle we produce.


Our Core Values

Our core values—Unconventional Innovation, Just Right Design, Experimental Engineering, and New Sustainable Future—define how we approach every project, from early design consultation to full production. These four principles are more than ideals; they are our daily practice in delivering performance and aesthetic harmony in every handle screw, knob fastener, and clamping handle we produce.

Unconventional Innovation

UJEN believes innovation starts by questioning convention. Our team continuously rethinks fastening mechanisms and material combinations to help OEM partners improve ergonomics, durability, and visual identity. Through extensive prototyping, CAE simulation, and mold-flow analysis, we develop optimized component geometries that enhance performance while simplifying assembly. This forward-thinking mindset enables us to deliver customized fasteners that redefine traditional industrial standards.

Just Right Design

Every detail matters in achieving precision that feels effortless. Our design philosophy—Just Right Design—integrates human-centered ergonomics with mechanical accuracy. From knurled knob profiles to adjustable handle torque mechanisms, UJEN ensures each product delivers the perfect balance between comfort, functionality, and aesthetics. Our in-house designers work closely with clients to co-create form factors that not only fit the machine but also elevate brand identity through color, texture, and tactile feedback.

Experimental Engineering

Engineering at UJEN goes beyond repeatability—it’s about exploration. We combine precision mold technology with cross-material engineering, experimenting with composites, glass-filled nylon, PEEK, and recycled fiber materials to meet the evolving demands of next-generation devices. This experimental spirit is supported by our fully equipped R&D and tooling center, where we simulate stress, fatigue, and tolerance performance under real-world load conditions. The result is a fastener that’s lighter, stronger, and more sustainable.

New Sustainable Future

Sustainability is not an afterthought—it’s the next evolution of design. UJEN integrates eco-friendly practices into product and process development, including PCR plastics, oyster shell powder composites, and renewable fillers that reduce carbon output and material waste. Our ISO 9001:2015 quality management system ensures that these innovative materials maintain consistency and reliability equal to virgin resins and metals. By combining circular material design with long-lasting performance, UJEN helps partners meet ESG objectives without compromise.

Quality System & Process Control

Behind every UJEN component lies a meticulous quality workflow. We operate under a comprehensive ISO 9001-certified system that covers every stage—from incoming material inspection to in-process control and final validation. Each batch of components is verified through precise manual measurement, visual inspection, and dimensional checks using calibrated instruments to ensure product stability and aesthetic consistency. All production records are documented for full traceability, enabling transparent quality assurance for global buyers.

Collaborative Engineering Partnership

Our team of bilingual engineers works directly with clients to translate design goals into manufacturable, cost-effective solutions. Whether you’re developing a new product line or optimizing an existing fastener assembly, we offer technical consultation, DFM feedback, and prototype validation to accelerate development while minimizing risk. This single-window project management approach ensures accountability and seamless communication from concept to shipment.

Commitment to Consistency

At UJEN, quality is measured not just by precision, but by repeatability. From tool calibration to resin drying, every parameter is standardized through our internal quality control procedures. We maintain zero-defect objectives, striving for a zero-negative feedback record across our global clients. Our continuous improvement mindset keeps UJEN aligned with international standards and future-ready for the next generation of fastening solutions.

In Summary

UJEN’s integrated quality and values system reflects our belief that great design is born from precision, collaboration, and responsibility. By combining technical excellence with environmental foresight, we ensure that every handle screw, knob fastener, and clamping component carries not only mechanical strength—but also the spirit of thoughtful engineering.
