Copper Coil Bending With A 63CNC-4A2S

Client Background

This customer is a professional metal-component manufacturer in Thailand, mainly processing copper heat-exchange tubes, metal frame parts and tubular accessories. Before working with Telhoo, the factory relied on old manual bending equipment with clear pain points:

• Low processing efficiency, heavily dependent on skilled workers
• Inconsistent bending angles and dimensional errors, with a high reject rate
• Unable to process multi-radius complex curved pipe, limiting product expansion

After comparing several machinery suppliers from China and local Thai manufacturers, the client chose Telhoo’s 63CNC-4A2S CNC pipe bender following a factory inspection, sample test and technical parameter verification.

Why The 63CNC-4A2S

The configuration was matched to the customer’s copper-tube production:

• 4-axis full-servo control + 2-stack multi-die design — switches between two bending dies without frequent disassembly, ideal for copper tubes with multiple bending radii.
• Heavy-duty hydraulic bending system — stable output force with no deformation and scratch-free forming for soft copper pipe.
• Intelligent CNC touchscreen control — programmable parameters storing hundreds of tube programs; new operators become proficient after short training.
• Thickened cast machine body — shock-resistant structure for long-term continuous operation without precision drift.

On-Site Commissioning & Production

Telhoo’s technical team completed overseas door-to-door installation, debugging and operator training at the customer’s Thailand workshop. Local operators now independently complete copper-coil feeding, positioning and bending, while supporting automated tooling gives one-stop forming of heat-exchange copper tubes and the auxiliary CNC console allows real-time parameter and program changes.

The Results In Production

Within the first production runs the 63CNC-4A2S changed the numbers the factory cares about. Bending that once depended on a skilled operator now runs to a stored program, so output rose about 65% against the old manual benders while the reject rate dropped around 80%. Every coil holds ±0.1° angle repeatability — which matters on copper heat-exchange tube, where a few degrees of drift can stop a finished coil nesting into its housing. Because the forming is scratch-free and the radii repeat batch after batch, the customer was able to open three new copper product lines that the old manual equipment could not hold to tolerance.

Just as important for a buyer overseas, the machine arrived export-packed, was installed and commissioned door-to-door by Telhoo’s team, and the local operators were trained on site — so the productivity gain landed in weeks, not months, with spare-parts support continuing afterwards.

The Bending Process Behind It

Copper is soft and thin-walled, so these coils are formed by rotary draw bending with mandrel support inside the tube: the bore is held round while the bend die wraps the copper, preventing the flattening and wrinkling that ruin heat-exchange performance. The same method runs on every Telhoo CNC and NC machine. Read more about mandrel tube bending and rotary draw bending, or see the full CNC automatic pipe bending machine range this 63CNC belongs to.
