Xiamen Sipu Mechanical Co., Ltd. has been a specialized manufacturer of precision coil winding machines and fully automated production lines since 2014.

Headquartered in Xiamen, China, with a 3,400 square meter modern production base, we focus on providing one-stop automation solutions for the global coil winding industry. Whether you need a standalone winding machine or a completely customized assembly line, SIPU delivers technology that reduces labor costs, ensures product consistency, and maximizes your production efficiency.

Our Journey: A Decade of Dedication

From a startup to a global exporter, every step witnesses our dedication to technology.

• 2014: SIPU Mechanical was established, defining "Precision Winding" as our core business direction.

• 2018: Expanded the factory to over 3,400 sqm and implemented a comprehensive Standardized Production Management System to ensure full traceability of machine quality.

• 2019: Established the Ningbo Technical Service Center to deeply serve the Yangtze River Delta industrial cluster.

• 2022: Formed an independent R&D team and achieved significant technological breakthroughs in automation.

• 2024: Expanded business globally, with equipment widely used in automotive electronics, home appliances, and industrial controls.

Factory Strength: Full Process Control

High-quality machines stem from high-standard manufacturing environments. We have divided our 3,400 sqm facility into four core zones to keep critical processes in-house:

1. CNC Precision Machining Center: Equipped with high-precision CNC machine tools to manufacture core mechanical components internally. We strictly control micron-level tolerances and refuse low-quality outsourcing.

2. Assembly & Commissioning Zone: Managed by a team of technicians with 5+ years of experience in mechanical assembly and electrical debugging.

3. Run-In & Testing Zone: All equipment must undergo a 72-hour continuous run-in test before shipment. This rigorous process simulates long-term operation to ensure stability and eliminate potential early failures.

4. Spare Parts Center: We stock over 5,000 types of standard parts to ensure rapid response to after-sales needs.

5. Customization Capabilities: We Build What You Need

Unlike trading companies limited to standard catalog products, SIPU is an engineering-driven manufacturer. Over 80% of our annual orders are customized solutions—we don’t just adapt, but engineer tailored solutions from the ground up to meet your unique production needs.

01. Deep Hardware Customization
We solve complex mechanical challenges that standard machines can’t handle:

• Wire Compatibility: From 0.025mm ultra-fine wires (micro-sensors) to 2.0mm+ heavy-duty wires (power inductors).

• Axis Expansion: Multi-spindle systems (up to 32 axes) for high-volume production.

• Complex Geometries: Custom fixtures/nozzles for non-standard or micro-bobbins (e.g., bone-conduction coils, RFID coils).

02. Software & Data Integration (Industry 4.0 Ready)
We deliver data-driven intelligence beyond basic operation:

• Custom Winding Algorithms: Tailored trajectories for orthocyclic or layer-stop winding.

• System Interfacing: Seamless integration with your MES/ERP systems (real-time production tracking, yield analysis).

03. Full-Process Integration (Turnkey Solution)
End-to-end automated lines to minimize labor dependency:

• Assembly Integration: Pin Insertion + Winding + Soldering + Assembly + Testing.

• Visual Inspection: CCD camera systems for automatic defect detection (wire breakage, soldering flaws).

• Robotic Automation: Robotic arms for flexible material loading.

Global Service Network

• Xiamen Headquarters: Global Marketing & R&D Center.

• Ningbo Center: Rapid response to the needs of China's largest manufacturing base.

• Remote Empowerment: Providing online video technical support for overseas customers, solving software setting issues via remote diagnosis.

• Global Installation: For large-scale production lines, we dispatch engineers to your site anywhere in the world for handover and training.

  
  

Certifications & Technologies

"Little Giant" Enterprise 

This government award recognizes SIPU as a "Hidden Champion" in the niche market. It proves we are specialized experts in coil winding technology, not general machinery traders.

FAQ

Q1: Can you customize the machine for my specific coil product?
A: Yes, absolutely. Customization is our key strength. Please send us your coil drawing and production capacity requirements, and our engineers will provide a technical proposal within 36 hours.

Q2: What brand of components do you use?
A: To ensure the equipment runs stably for over 10 years, we refuse cheap parts. We mainly use:

• Servo Motors: Panasonic / Mitsubishi

• Pneumatics: AirTAC 

• Linear Guides: HIWIN

• Electric Parts: Schneider

Q3: What is the warranty period?
A: We provide a 12-month warranty for the whole machine. During the warranty period, if there is any non-human damage, we will send replacement parts via express courier for free.

Q4: What is the lead time for your machines?
A: For standard winding machines, the lead time is typically 2-3 months. For customized fully automatic production lines, it usually takes 4-5 months depending on the complexity of the design.

Q5: How do you handle voltage differences (e.g., 110V vs 380V)?
A: We ensure the machine is fully operational in your facility. Based on your local voltage (e.g., 110V/220V/415V), we will equip the machine with a high-quality dedicated transformer. This ensures stable voltage output and protects the internal precision components. You can use the machine directly upon arrival without purchasing any extra equipment.

Q6: How is the machine packaged for overseas shipping?
A: We strictly follow international export packaging standards (using reinforced fumigation-free plywood cases) to prevent rust and damage. We can also customize the packaging method according to your specific requirements.

Q7: What payment terms do you accept?
A: Our standard payment term is T/T (Telegraphic Transfer): 50% deposit to start production, and the remaining 50% balance to be paid before shipment.

Q8: Do you provide English manuals and operation videos?
A: Yes. Every machine comes with a detailed English User Manual, Electrical Schematics, and step-by-step Operation Videos to help your engineers master the machine quickly.
