One-Stop Workflow
Integrated Manufacturing Process
Speed and coordination define modern manufacturing. UJEN’s one-stop workflow integrates design, mold development, material selection, forming, finishing, assembly, and packaging into a single, traceable path—built for handle screws, knob fasteners, spring plungers, and adjustable clamping handles. This approach shortens validation cycles, reduces communication risk, and keeps quality consistent from pilot runs to mass production.
Concept Design & DFM (Design for Manufacturability)
We begin with your target use case, torque and load requirements, and interface constraints. Our engineers provide DFM feedback on geometry, draft angles, gate placement, wall thickness, and tolerance stacking. Early co-design ensures mechanical performance while preserving ergonomics and brand styling.
Parallel Prototyping & Mold Strategy
To compress timelines, we plan prototype builds and tooling in parallel. For early validation we offer soft tooling, quick-change inserts, and 3D-printed jigs and fixtures. The mold strategy clarifies cavity count, runner type, ejection, cooling, and expected cycle time—so you can estimate total landed cost with confidence.
Tooling Workflow (R&D & Tooling Center)
Our tooling team manages the full loop: design review → 2D/3D mold design → CNC roughing and finishing → EDM → fitting → trial (T0/T1/T2) → optimization. We document key parameters (temperature, pressure, fill time) for reproducibility and use gauge checks on critical dimensions before releasing for pilot production.
Materials Gateway & Compliance
We source and validate materials across plastics and metals to match performance and regulatory needs:
- Engineering plastics: PA, POM, ABS, PC, TPR, and glass-fiber reinforced options
- High-performance: PEEK for heat and chemical resistance
- Eco options: PCR resins, oyster-shell and wood-fiber composites for reduced plastic content
- Metals: zinc/aluminum die-casting alloys, carbon steel, stainless steel, tool steel, forged aluminum
Each selection balances strength, weight, appearance, cost, and downstream finishing feasibility.
Forming Processes
- Plastic injection molding (standard, GF-reinforced, or multi-material where applicable)
- Die casting (zinc/aluminum) for robust metal components and housings
- Cold forging and forging for high-strength shafts or levers
- CNC turn-mill machining for precision threads, stems, and custom interfaces
- Stamping and springs for clips or displacement elements when needed
Surface Finishing & Precision Marking
We deliver both protection and aesthetics through finishing: sandblasting, anodizing, heat treatment, zinc plating, electroless nickel, e-coating, painting, passivation, black oxide, and anti-corrosion coatings. Markings such as laser engraving, pad printing, and silk-screening support branding, orientation cues, and traceability without compromising durability.
Assembly, Functional Tests & Pilot Runs
Assemblies—such as knob screws with stems, washers, and anti-scratch tips, or pull pins with springs and detents—are built with standardized SOPs. We conduct functional checks (torque feel, detent force, cycle durability) and dimensional audits on critical-to-quality features before pilot shipments.
Packaging, Labeling & Logistics
We design packaging for safe transit and efficient line-side use: unit bags with labels, sub-cartons with part and lot info, export cartons with stacking specs. Sustainable options using up-cycled or reduced-plastic materials are available. Global shipments via air or sea follow your INCOTERMS and consolidation needs.
Timeline Control & Single-Window Management
Your dedicated project manager owns the schedule from RFQ to mass production. Milestones include DFM sign-off, tooling kick-off, T0/T1 trials, pilot acceptance, and mass production readiness. We maintain a single communication channel to minimize misalignment across suppliers and processes.
Documentation & Traceability
For each phase we maintain drawings, BOM, material certifications, RoHS/REACH compliance (when required), trial reports, and inspection records. Lot IDs and production parameters are recorded for backward traceability and consistent re-orders.
Ramp-Up to Mass Production
Once pilot results meet targets, we finalize work instructions, capacity plans, and safety stocks. Preventive maintenance schedules are locked with tool life tracking. The hand-off includes packaging specs, labeling, and logistics routines—so scaling to 10,000–100,000+ units stays predictable.
In Summary
UJEN’s one-stop workflow aligns design precision with manufacturing discipline. By managing DFM, tooling, forming, finishing, and assembly under one coordinated plan, we help you launch faster and scale with confidence—across handle screws, knobs, spring plungers, and clamping handles for demanding industrial applications.
