Product SpecificationsThe Preah Sihanouk province, anchored by the rapid infrastructure expansion of the Sihanoukville Special Economic Zone (SSEZ) and the deep-water autonomous maritime terminal, has evolved beyond light apparel manufacturing into an advanced engineering hub for automotive electrical components, light electric vehicles (LEV), water treatment pumps, and consumer electronic motors. In this transformational phase, motor manufacturers establishing production footprints require automated stator winding, coil embedding, wedge insertion, and trickle impregnation lines capable of delivering consistent electromagnetic performance under tropical operating conditions.
Zhejiang Rilvo Automation Equipment Co., Ltd. serves as an end-to-end original equipment manufacturer (OEM) and technology exporter tailored specifically to the operational parameters of Sihanoukville enterprises. Operating from our 60,000-square-meter facility with over 36 senior research engineers and more than 150 high-precision CNC machining centers, Rilvo integrates mechanical indexing, servo-actuated tension control, and hot-stake resistance spot welding into fully synchronized turnkey manufacturing systems. By delivering direct from our Zhejiang headquarters via direct maritime freight routes into the Port of Sihanoukville (PAS), we minimize import lead times while offering comprehensive turnkey setup, tooling customization, and on-site engineering commissioning.
Multi-axis electronic gearing systems eliminate copper wire elongation and enamel micro-fissuring, ensuring exact magnetic flux distribution across 2-pole to 72-slot stator configurations.
High-efficiency slot insulation wedge insertion with adjustable cuff lengths and high-grade DMD/Nomex dielectric materials, maintaining slot boundary dielectric integrity beyond 2.5 kV.
Constant-current DC inverter power supply units featuring dynamic resistance feedback to guarantee zero cold-welds and exceptional pull-off mechanical shear strength on starter armatures.

Deploying automated stator winding lines within the Sihanoukville ecosystem demands robust environmental adaptability and precision tooling due to the coastal climate and specific localized industry segments:
1. Electric Two-Wheeler (E-Bike) and Light EV Mobility Production: As Cambodia accelerates green transportation policies, industrial assembly parks along National Road 4 increasingly focus on permanent magnet brushless DC (BLDC) hub motors and mid-drive motors. The CT-40 Automatic Magnet Inserter combined with the ZB-303 Three-Servo Rotor Winding Machine delivers high-yield slot-fill ratios and balanced magnetic symmetry, directly reducing cogging torque and motor operational heat.
2. Submersible, Agricultural, and Commercial Water Pump Stators: The coastal fishing fleets, aquaculture infrastructure, and inland irrigation zones around Kampong Som require sealed AC induction motors resilient against voltage fluctuations and high humidity. Our XB-1GZ Coil Winding and DQ-1 Wire Embedding lines facilitate dense copper wire slot compaction, coupled with automated trickle varnish impregnation (DQ-226/100) to ensure Class H dielectric insulation.
3. Automotive Starter Motors and Alternator Component Remanufacturing: Benefiting from Sihanoukville's free-trade incentives, several Tier-2 export manufacturers specialize in alternator stators and starter armatures for global export. Our specialized DFC-1 Wedge Paper Inserting System and 4-BL-1 Wave-Shape Coil Winders reduce manual labor requirements by 75% while improving end-turn coil geometry consistency.
Rising regional labor costs and the SSEZ’s shift toward capital-intensive assembly encourage manufacturers to replace manual tabletop winders with integrated PLC-controlled multi-spindle lines.
Equipment exported to Sihanoukville features nickel-chrome anti-corrosion plating on guide needles, sealed IP54 electrical enclosures, and air-conditioned PLC cabinets to withstand marine salinity.
The geographic proximity between Ningbo Port and Sihanoukville Autonomous Port enables express 7-10 day containerized shipping for tooling modules, wear-part nozzles, and expansion fixtures.
Established in 1998 in the Shatianyang Development Zone of Sanmen, Taizhou, Rilvo is recognized as a premier provincial High and New Technology Enterprise. Led by our president and chief engineer—honored with the National Knowledge-Worker Model award by the All-China Federation of Trade Unions—we maintain total autonomy over our machining, heat treatment, optical inspection, and firmware engineering.
Spanning nearly 60,000 m² of industrialized manufacturing space, our facility operates 6 automated production lines dedicated to micro-motor equipment, commutator spot welders, flat-wire hair-pin forming systems, and electrostatic powder coating lines. We back our exports with genuine factory-direct engineering accountability, verifiable ISO9001 compliance, China Compulsory Certification (3C), and 17 proprietary national patents.
Clear, direct answers regarding custom tooling, shipping protocols into Cambodia, electrical adaptation, and life-cycle technical support.
Yes. Every winding needle diameter, coil shedding blade, slot wedge guide, and transfer fork is tailored to your stator core drawings, slot count, stack height, and wire gauge. We fabricate tooling using our in-house CNC centers and perform sample verification runs prior to container loading.
Our Sanmen factory is located approximately two hours from Ningbo Port. Standard direct sea freight from Ningbo to Sihanoukville Autonomous Port (PAS) requires 7 to 10 days of voyage time. We provide full export documentation including Certificate of Origin (Form E) to enable tariff preferences under ASEAN-China FTA frameworks.
Machinery built for Sihanoukville includes anti-oxidation surface coatings on all exposed carbon steel and sliding tables, nickel-plated winding guides, and forced cabinet ventilation with optional closed-loop air conditioners to protect Omron/Mitsubishi PLC electronics against salt-air humidity.
Our electrical architectures are built to 380V ±10% 3-phase 50Hz by default, perfectly matched to industrial grid standards across the SSEZ and Preah Sihanouk province. Step-up/step-down transformers and voltage stabilizers can be integrated directly inside the main power distribution cabinets upon request.
We provide full pre-delivery FAT video inspection using customer-supplied stator laminations and magnet wire. Following site delivery, our senior automation engineers are available for on-site positioning, line balancing, and factory staff training, complemented by remote 24/7 video support and rapid spare parts dispatch.
We support FOB (Ningbo/Shanghai), CFR, CIF (Sihanoukville), and EXW terms. Payments are processed via T/T wire transfer in USD or EUR, supported by structured milestone arrangements for custom multi-station production lines. The minimum order quantity is one set.
Submit your stator/rotor lamination CAD files, wire specifications, and expected cycle times. Our senior engineering department will deliver a customized process proposal, tooling matrix, and CIF Sihanoukville quotation within 24 hours.
