YG Machinery supplied a YGT 5-16 rebar straightener to a precast concrete factory in Surabaya, Indonesia. The factory needed to produce thousands of straight rebar pieces every day. Manual straightening and cutting could not keep up with demand.
The YGT 5-16 solved the problem. It runs continuously for eight hours a day. It processes 14mm rebar with ±1cm accuracy. Daily output increased by 40%. The factory owner said they have not had a single breakdown in six months.
Customer Background
The precast concrete factory in Surabaya makes concrete panels, beams, and columns for residential and commercial construction. Their work requires large amounts of straight rebar cut to precise lengths.
Before buying the rebar straightener, production was often delayed. Manual processing was slow. The factory needed a faster, more reliable solution.
Why a Precast Factory Needed a Rebar Straightener
Manual rebar processing has several problems. Workers must straighten bent bars by hand. Then they measure and cut each piece individually. This takes time and labor.
Common issues with manual processing include:
- Inconsistent cut lengths
- High material waste from bad cuts
- Slow output during peak demand
- Workers get tired, and quality drops
For a precast factory, slow rebar processing means late concrete pouring. Late pouring delays the whole project. The factory needed an automatic rebar straightener that could keep up with production.
How the Factory Found YG Rebar Straightening Machine
Mr. Darmawan first saw a rebar straightening machine on Amazon. The product looked good, but the seller could not answer technical questions about Indonesian voltage and rebar sizes.
He searched Google for “rebar straightener for sale” and found several suppliers. He compared prices, specifications, and after-sales support.
YG Machinery stood out for three reasons. First, the YGT 5-16 handled 5-16mm rebar, which matched his needs. Second, the machine had microcomputer control for easy operation. Third, YG offered a clear price with no hidden fees.
Mr. Darmawan contacted YG. Our sales manager answered his questions within a few hours. He asked about daily output, rebar sizes, and power supply. Then he recommended the YGT 5-16 with a variable frequency drive for adjustable processing speed. This custom configuration allows the factory to switch between different rebar sizes without slowing down.
Mr. Darmawan placed an order.
YGT 5-16 Rebar Straightener
Here is what the factory received:
| Specification | YGT 5-16 |
| Diameter range | 5-16mm (Grade III steel) |
| Wire pulling speed | 50m/min |
| Traction motor power | 2.2kw-6 |
| Straightening motor power | 15kw-4 |
| Cutting motor power | 5.5kw-4 |
| Cutting error | ±0.5-1cm |
| Wire length | 800-9000mm (can be extended) |
| Straightening degree | ±2 mm/m |
| Weight | 1500kg |
| Power requirement | 380V three-phase |
This rebar straightener also cuts. It straightens bent rebar, then cuts it to the preset length. The microcomputer control lets operators set length and quantity by pressing numbers.
The custom configuration includes a variable frequency drive. This allows the operator to adjust the processing speed for different rebar diameters. Thinner rebar runs faster. Thicker rebar runs slower but stays stable. A reinforced feeding rack was also added for heavy-duty use.
Core Features of This Rebar Straightening and Cutting Machine
Microcomputer control. Set length and quantity by pressing numbers. Anyone can operate this rebar straightener.
Automatic operation. Straightening, length measurement, and cutting are all automatic. No manual measuring.
High cutting accuracy. ±0.5-1cm error. No wasted material.
Fast processing speed. 50m/min pulling speed. Processes 14mm rebar with ease.
Removes surface rust. The straightening process also removes rust and oxide scale from the rebar surface.
Variable frequency drive (custom). Adjustable speed for different rebar diameters. Switch between sizes without slowing down.
Durable construction. Built for long hours of continuous operation.
Implementation and Results
The YGT 5-16 arrived at the Surabaya factory within four weeks. YG provided remote training. The team learned to operate the rebar straightener in one day.
The factory installed the machine at the rebar processing area. The operator sets the length and quantity on the microcomputer panel. The machine feeds, straightens, measures, and cuts automatically.
The results were clear:
- Daily output increased by 40% compared to manual processing
- Processing accuracy improved to ±1cm error
- Waste material reduced by precise cutting
- Labor requirement reduced from six workers to two
- Machine runs continuously for eight hours a day, five days a week
- No breakdowns in six months
The factory processes rebar for concrete panels, beams, and columns. With the YGT 5-16, they never fall behind on rebar preparation.
Customer Feedback
Mr. Darmawan told us:
“We have not had a single breakdown in six months. This rebar straightener runs every day without problems. Daily output is up 40%. Our workers learned to use it in one day. We are very satisfied.”
He has since recommended the machine to another precast factory in Surabaya.
