Supply Chain Excellence
China OEM/ODM Manufacturing: Precision, Scale & Metallurgy
Jiangmen Heikki Technology Co., Ltd. leverages over 30 years of vertical industrial integration. We control copper terminal stamping, flame-retardant polymer synthesis, high-frequency wave soldering, and automated safety screening under one ISO-certified roof.
Phosphor Bronze Stamping
Unlike budget multi-plug outlets utilizing riveted scrap brass, our factories deploy 0.6mm–0.8mm single-piece integrated high-elasticity tin-phosphor bronze conduction strips. This reduces internal thermal buildup by up to 38% and guarantees over 10,000 smooth insertion-extraction cycles without loose pin grip.
750°C Glow-Wire Flame Retardance
Molded from virgin Polycarbonate (PC) and Acrylonitrile Butadiene Styrene (ABS) alloy, each housing withstands standardized UL94 V-0 and IEC 60695-2-11 glow-wire tests up to 750°C. If an accidental overload occurs, thermal combustion is self-extinguished within 10 seconds, eliminating structure dripping.
75N Dual Child Safety Shutters
Child safety is paramount in both domestic and public environments. Our multi-plug outlets integrate independent bi-directional safety protection shutters requiring a minimum insertion pressure of 75 Newtons (7.65 kgf). This effectively blocks unilateral foreign object insertions, such as pens or wires.
Multi-Stage Surge Clamping (MOV)
Critical electronic equipment requires clean AC current. Our internal PCB design incorporates custom Metal Oxide Varistors (MOV) with Transient Voltage Suppression (TVS) diodes and thermal cutoff fuses capable of suppressing transient spikes up to 1050 Joules, safeguarding sensitive connected computing assets.
Direct-from-Source Price Advantage
By owning a modern 30,000+ m² facility within the Greater Bay Area hardware cluster, Heikki eliminates trading layers. We handle internal tooling, high-precision automated injection, cable extrusion, and package printing, allowing overseas importers to secure an extra 12% to 22% gross margin headroom.
100% In-Line Computerized Testing
Every single manufactured unit is passed through a comprehensive five-stage digital test console before blister or carton packing: Ground Continuity Inspection, High-Voltage AC Dielectric Breakdown (1500V/1min), Contact Resistance, Full-Load Temperature Rise, and USB Fast-Charging Dynamic Protocol Emulation.

Industry Foresight & Procurement Analysis
Emerging Industry Trends in Power Extension Engineering
Global consumer electronic habits and green building efficiency standards are shifting power strip manufacturing requirements. As a pioneering factory, Heikki incorporates advanced technologies into standard commercial production.
GaN Fast Charging Integration
Traditional bulky AC wall adapters are rapidly becoming obsolete. Next-gen extension boards incorporate Gallium Nitride (GaN III) high-efficiency power delivery modules (30W, 45W, and 65W PD 3.0). This provides full laptop charging capacity directly through USB-C ports while decreasing internal operating heat.
Individual Sub-Circuit Switching
In response to global standby power consumption regulations and energy conservation directives, individual mechanical switches paired with low-glow micro-LED indicators enable end consumers to isolate unused appliances instantly, effectively curtailing phantom electrical draw.
Matter & Tuya IoT Smart Integration
Modern smart home and office setups require wireless protocol flexibility. Our ODM pipeline offers multi-socket models embedded with Tuya Wi-Fi, BLE mesh, or Matter micro-controllers, enabling power consumption monitoring, app-based scheduling, and voice command via Amazon Alexa and Google Assistant.
Ultra-Compact Flat 45° Angled Plugs
Urban real estate demands slim furniture placement. We produce low-profile right-angle plugs (8mm–12mm profile) that fit flush against baseboard wall receptacles. The 45-degree cord exit angle avoids obstructing the secondary wall outlet in standard duplex setups.
Wide-Spaced Transformer Outlets
Standard AC power bricks often overlap adjoining sockets, rendering them unusable. Heikki's spatial CAD tooling integrates wide-pitch center spacing (up to 55mm pitch), enabling large transformer power adapters to plug in side by side without physical interference.
Eco-Friendly Packaging & PCR Resin
To support global carbon zero targets, Heikki provides Post-Consumer Recycled (PCR) polymer options for housing molding, alongside 100% plastic-free soy-ink printed unbleached kraft paper gift boxes to comply with upcoming EU Packaging Waste Regulations (PPWR).
Operational Deployment
Engineering Fit for Purpose: Global Application Scenarios
Power strips are deployed in distinct environmental conditions requiring tailored configurations. We engineer structural variations to ensure safety under extreme use cases.
Corporate Workstations & AV
Modern office environments require clutter-free power routing. Our commercial multi-plug extensions feature under-desk clamp brackets, recessed keyhole slots, EMI/RFI noise filtration, and high-wattage USB-C hubs for laptops, monitors, and video conference equipment.
Heavy Workshop & Industrial
Industrial settings subject equipment to impacts and continuous motor draw. We produce heavy-duty multi-gang lines with thick rubberized anti-shock corner bumpers, 3G 1.5mm²–2.5mm² pure copper cords, IP44 water-resistant covers, and 16A automatic overload switches.
Hospitality & Residential
Hotels and residential dwellings prioritize safety and seamless aesthetics. Our universal power strips integrate child safety shutters, curved scratch-resistant matte finishes, and subtle power status indicators designed to eliminate nighttime sleep disturbance.
International Travel & Nomad Hubs
Global mobility requires multi-standard compatibility. Our lightweight travel extension sockets integrate folding multi-plug configurations, wide voltage tolerance (100V–250V), and interchangeable modular pin systems for seamless global use.

Frequently Asked Questions for Importers & Wholesalers
Get verified answers to technical parameters, OEM minimum order quantities, compliance timelines, and global factory logistics.
What are the key engineering differences between low-cost and high-quality multi-plug extension sockets?
The differences center on internal conductive metallurgy, fire retardance, and contact mechanics. Substandard power strips use recycled brass pieces linked by hand-soldered wires, leading to contact resistance, voltage drops, and fire hazards under heavy loads. High-grade industrial sockets from Jiangmen Heikki utilize one-piece stamped phosphor bronze strips (CuSn6.5 / C5191), 100% pure copper conductors in the cord (minimum 3x0.75mm² or 3x1.25mm² based on current rating), virgin flame-retardant PC/ABS plastics tested to UL94 V-0, and mechanical spring shutters designed for 10,000+ insertions without deformation.
What is the standard Minimum Order Quantity (MOQ) and production lead time for custom OEM orders?
For standard production models with customized silk-screen brand logos and client-designed retail color boxes, our standard MOQ is generally 1,000 to 2,000 units per model. For bespoke industrial tooling (custom housing shapes, unique socket arrays, or proprietary internal PCB designs), MOQ is determined by mold amortization, usually beginning at 5,000 units. Standard mass production lead times run between 25 to 35 calendar days following golden sample confirmation and deposit receipt.
Can Heikki provide localized certification support for our country's import customs clearance?
Yes. We provide complete technical files and testing support for international certification regimes. Our product models have secured SASO / SQM (Saudi Arabia), GCC Conformity, ESMA/ECAS (UAE), BS 1363 (Hong Kong/UK), SS 145 (Singapore), MS 589 (Malaysia), PS Mark (Philippines), TISI (Thailand), KC (South Korea), SONCAP (Nigeria), and CE/UKCA directives. We supply factory CB scheme test reports from accredited ILAC-MRA laboratories (such as TUV, SGS, and Intertek) to expedite local market registration.
How do you manage quality control across high-volume production runs?
Our quality assurance system operates under ISO 9001, ISO 14001, and ISO 45001. We execute an end-to-end multi-gate quality process: Incoming Quality Control (IQC) verifies raw copper strip spring tension and polymer melt indices; In-Process Quality Control (IPQC) performs hourly pull-force and automated solder joint checks; 100% automated electrical end-of-line testing checks ground continuity, 1500V dielectric insulation resistance, and polarity; and Outgoing Quality Control (OQC) conducts AQL 1.0/2.5 sampling checks before container loading.
Is it possible to customize extension cord length, plug types, and USB charging configurations?
Yes. Full modular customization is the core of our OEM/ODM service. You can specify power cord length (1.5m, 2m, 3m, 5m, up to 10m heavy-duty lengths), cable cross-sectional area (0.75mm², 1.0mm², 1.5mm², 2.5mm² or 14/16 AWG), wall plug configurations (UK Type G, EU Schuko Type F, US NEMA 5-15P, Thai TISI, etc.), and fast-charging USB boards ranging from budget 5V/2.4A configurations to advanced GaN 65W PD 3.0 Type-C smart distribution circuits.
