Integrated Manufacturing Overview

Integrated Manufacturing for Handle Screws & Fastening Components

In 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.


One-Stop Manufacturing Solution for Handle Screws & Fastening Components

By combining product design, precision mold development, material selection, forming processes, and surface finishing, we transform your concepts into high-performance fastening components ready for global markets.

Integrated R&D and Precision Mold Development

Our in-house R&D and tooling center manages every phase—from concept design and DFM (Design for Manufacturability) to mold trials and refinement. This ensures dimensional accuracy for adjustable handles, spring pull pins, and knob screws across industries such as fitness equipment, medical devices, and industrial machinery.

Single-Window Project Management for OEM/ODM Buyers

UJEN simplifies complexity with a single-window project management model. Dedicated project managers coordinate communication, timeline control, and supplier alignment— reducing risks from miscommunication and ensuring traceable progress from prototype to mass production for custom handle screw manufacturing.

Faster Development with Rapid Prototyping

We execute mold design and prototyping simultaneously, cutting early-stage project time by more than 40%. This agile approach allows clients to validate ergonomics, structure, and function before mass production—ideal for handle screw assemblies and precision fastening systems requiring quick iteration.

Flexible & Scalable Production Capacity

From a single functional prototype to mass production exceeding 100,000 units, UJEN’s facilities support plastic injection, die casting, CNC machining, and hybrid forming. We deliver consistent quality for clients across automotive, aerospace, electronics, and industrial sectors.

ISO-Certified Quality Assurance

Operating under an ISO 9001-certified quality management system, UJEN ensures total process control and inspection. We use automated visual inspection and digital dimensional measurement to guarantee tolerance, finish, and performance consistency. Our handle screws and fastening components are engineered for reliability under torque, vibration, and load-bearing conditions.

Sustainable Manufacturing for a Greener Future

Guided by our “New Sustainable Future” philosophy, UJEN integrates PCR recycled plastics, oyster-shell biocomposites, and biomaterial-based additives into our production. These materials reduce plastic waste and carbon emissions while maintaining structural integrity, helping global clients achieve their ESG goals without compromising product performance.
