Solar Panel Frame Roll Forming Machine — Built for 3 mm Frames

HOPEX-Solar Panel Frame

Three problems ruin frame production: springback on heavy gauge, hole position drift, and tooling wear that slowly changes the section. This solar panel frame roll forming machine is configured against each of them.

Problem 1 — Springback on Heavy Gauge

Frame members are formed from 2.0 – 3.0 mm material. Bending that thickness in too few passes leaves the section opening up after it leaves the last roller.

How this line answers it

• 26 roller stations distribute the bend so no single pass overworks the material.
• 80 mm solid shaft keep roller centres fixed under separating force.
• 8000 kg machine mass absorbs the reaction instead of flexing.

Problem 2 — Hole Position Drift

If holes wander along the length, frames will not bolt to the rail pattern on site and the whole batch becomes rework.

How this line answers it

• Servo feeding indexes the strip to the punch rather than relying on line speed.
• 11 KW × 2 hydraulic punching delivers full force even at 2.0 – 3.0 mm.
• PLC control stores the hole pattern so repeat orders reproduce exactly.

Problem 3 — Tooling Wear Changing the Section

Soft tooling erodes gradually. The first hundred frames measure correctly and the thousandth does not.

How this line answers it

• Rollers in Cr12MoV, quenched HRC 58–62.
• Shafts in 45# steel, forged, 0.05 mm chrome plated, so the mounting surfaces resist fretting.

Machines are built in Tianjin, China and carry a 2 years warranty. Engineers respond to technical enquiries within one hour during business hours.

Questions Fabricators Ask

Q1. Will 3 mm material damage the tooling?

No. Rollers are Cr12MoV, quenched HRC 58–62, selected for continuous heavy-gauge duty.

Q2. How repeatable is the hole pattern?

Servo feeding indexes each punch cycle independently of line speed, and the pattern is stored in the PLC.

Q3. Can the line run thinner material as well?

Yes, the range is 2.0 – 3.0 mm.

Q4. What output should we plan for?

10 – 20 m/min sustained.

Q5. How long is delivery?

30 days for one set, 45 days for 2–5 sets.

Q6. Is customisation possible?

Minor, drawing-based, sample-based and full customisation are all supported.
