Customer Story | 3 sets of ST-FL70F Tube Laser Cutters Boost Efficiency for Korean Pipe Manufacturer

Fondo

Our client, S Company, is a well-known Korean manufacturer of cast iron pipes and fittings, specializing in the production of pipeline components for various industrial applications.
With the growing production demand, the client aimed to improve cutting efficiency while maintaining clean and residue-free pipes, which are critical for their product quality.

Technical Requirements

• Inner diameter: φ14.28 mm – 57 mm
• Thickness: 1 mm
• Cutting length: 40–500 mm
• Material: Stainless Steel (SS)
• Special requirement: Slag removal system
• Capacity targets:
• Small pipe model: ≤100 mm, 800 pcs/hour
• Medium pipe model: ≤100 mm, 500 pcs/hourLarge pipe model: ≤100 mm, 400 pcs/hour

Desafío

The client first reached out to us after watching our ST-TP120 model with water-flow slag removal video online.
After careful technical discussion, our engineers found that while the ST-TP120 is an excellent choice for larger pipes, the client’s smaller pipe inner diameters (as small as φ14.28 mm) required a more compact and faster cutting solution.

For this reason, we recommended the ST-FL70F full-automatic cutting machine with copper-tube slag removal, which provides higher cutting efficiency y better adaptability for narrow pipes.

Additionally, since the client’s smallest pipe size was smaller than the standard slag-removal copper tube, our team customized thinner copper tubes specifically for their production needs.

Nuestra solución

After we proposed the technical plan, the client’s technical manager, overseas manager, and company president visited our factory in person to review and confirm the final configuration.
Together with our engineers, we optimized the details of the feeding system, slag removal mechanism, y cutting process parameters.The final solution consisted of three sets of ST-FL70F automatic cutting machines, each tailored to a specific pipe diameter range.
This setup ensured both high-speed performance and excellent cleanliness of the pipe interior — perfectly matching the client’s quality goals.

Inspection and Delivery

Once the machines were completed, the client come to our factory for the final on-site inspection.
They carefully reviewed the operation process including automatic loading, cutting, and slag removal for each unit.The machines passed the inspection successfully, and the client expressed full satisfaction with the performance, authorizing us to proceed with shipment immediately.
All three machines were then shipped to Incheon, South Korea, and are now ready for installation and operator training.
