Manufacturing Stages
Eight-Step Controlled Production Workflow
From flame-retardant raw polymer inspection to final shipping cartons, every manufacturing step is executed in-house with standard operating procedures and documented inspection points.
01
02
Precision Injection Molding
Automated molding cells produce dimensionally consistent housing components, child safety shutters, and internal isolators.
03
Conductor Welding & Joining
Heavy-duty ultrasonic and resistance welding creates low-resistance, heat-dissipating joints between terminals and PCB modules.
04
Fiber Laser Marking
Permanent high-contrast laser etching of ratings, CE/GS certification markings, batch tracking numbers, and custom client logos.
05
Component Assembly
Skilled operators assemble switches, overload reset buttons, USB PD fast-charging boards, and safety shutter blocks.
06
100% Inline Electrical Testing
Every individual unit is tested for ground continuity, short circuits, polarity accuracy, and rated dielectric breakdown voltage.
07
Protective Packaging
Retail color box, blister card, or master carton packing with anti-scratch films, custom barcodes, and Amazon FBA carton labels.
08
Finished Goods Dispatch
Final outbound AQL sampling audit, pallet shrink-wrapping, and systematic container loading for fast ocean transit.
Production Facilities
Modern Equipment & High-Yield Workshops
Investment in dedicated machinery allows Ningbo Sykra Technology Co., Ltd. to maintain high production precision, reduce scrap rates, and ensure scalable volume delivery.
Injection Molding Machinery
Equipped with multi-cavity precision molds for rapid cycle output, high tensile shell strength, and consistent fire-retardant wall thickness.
Automated Welding Station
Provides uniform weld depth and high tensile joint strength between internal copper buss bars, eliminating open-circuit risks during transit.
High-Speed Laser Station
Enables sharp vector engraving of complex electrical diagrams, client corporate logos, and European regulatory icons with zero ink smudging.
Integrated Assembly Lines
5 dedicated production lines configured for fast switchover between standard cube sockets, vertical towers, and rotating wall strips.
Staging & Pre-Assembly Area
Organized buffering system ensures lean inventory control, protected wire harness storage, and rapid restocking for high-velocity runs.
Automated Packaging Bay
Equipped with heat-shrink tunnels, carton sealing units, and weight-check scales to avoid missing accessory units in master cartons.
Quality Management Lab
In-House Safety Testing & Verification Lab
Safety is the foundational principle of all Sykra products. Our internal quality control laboratory is equipped with calibrated testing machinery to verify compliance with EN 61643, DIN VDE 0620, IEC 60884, and related international standards.
Contact Resistance Tester
Measures micro-ohm resistance across plug pins and outlet leaves to prevent abnormal thermal buildup under continuous 16A operating loads.
High-Voltage Dielectric Tester
Applies proof voltages up to 3,750V AC between live conductors and external casing to guarantee absolute user insulation protection.
Overload & Endurance Tester
Simulates continuous power draw scenarios up to 4,000W, cycling on/off loads to verify switch contact life and bimetal breaker reliability.
Safety Regulation Tester
Consolidated workstation for leakage current testing, grounding impedance measurement, and automated safety fault triggers.
Climate & Humidity Chamber
Subjects sockets to extreme tropical and cold environments (-20°C to +85°C at 95% RH) to evaluate resin aging and anti-tracking resistance.
Glow-Wire Flammability Chamber
Verifies plastic housings against hot glowing wire up to 750°C/850°C, verifying flame self-extinguishment within 30 seconds.
| In-House QA/QC Laboratory Capabilities | |
|---|---|
| Full Electrical Verification | Ground continuity (<0.1Ω), insulation resistance (>5MΩ at 500V DC), dielectric withstand test (1,500V to 3,750V AC). |
| Mechanical Endurance | Socket shutter cycling (10,000+ insertions), switch toggle life testing, and cord retention pull tests up to 100N. |
| Thermal & Fire Safety | Hot glow-wire flammability verification (IEC 60695-2-11) and ball pressure deformation tests at 125°C. |
| Environmental Stress | Thermal shock, salt spray corrosion testing for brass prongs, and 48-hour continuous climate conditioning. |
