Profile Information
Z beam is used in dishwasher structural frames, featuring asymmetric Z-shape for strength and assembly support, with multiple size variations for different appliance designs.
Z beams typically use 0.8–1.5mm galvanized steel for corrosion resistance, structural stability, and compatibility with high-speed forming and precision punching processes.

Machine Details
Steel Coil Decoiler With Leveler
The decoiler and leveling integrated unit combines coil unwinding and material flattening in one compact system, reducing space and improving feeding stability.
Compared to separated machines, it ensures better synchronization and lower investment cost. Leveling rollers remove coil stress, which is critical for maintaining forming accuracy and punching precision.
Roll Forming Machine
The wall panel chain-driven roll forming machine ensures stable forming of thin 1.2mm material, providing consistent profile accuracy.
Compared with gearbox structures, it offers cost efficiency, easy maintenance, and sufficient rigidity for light structural appliance profiles.
| Speed | 10-12m/min | Forming Station | 12 Stands |
| Motor Power | 7.5Kw | Shaft Diameter | 76mm, solid |
| Driving System | Chain | Roller Material | Gcr15,HRC58-62° |
| Frame Structure | Wall panel | Shaft Material | 40Cr heat treatment |
Flying Hydraulic Punch
This production line uses a flying punching system, meaning the roll forming process does not stop during punching.
To avoid deformation caused by material movement, the punching unit synchronizes with forming speed, creating relative static conditions. Hole patterns are fully customized according to client drawings.
Flying Hydraulic Cut
The flying hydraulic cutting system moves synchronously with the formed profile, allowing continuous production without stopping. This ensures clean cutting edges, maintains dimensional accuracy, and significantly improves overall production efficiency for high-volume manufacturing.
Auto Bending Machine
The bending machine performs dual-point forming after cutting, enabling precise angle control and consistent geometry. It eliminates secondary operations, improves production efficiency, and ensures repeatable bending accuracy for thin-walled Z profiles in high-volume manufacturing.
Safety Designs
Chain covers are installed to protect operators and extend chain service life. Full-machine mesh covers (slidable) provide visibility with safety. Flip-type covers ensure convenient access with enhanced protection.
Safety signs are applied to continuously alert operators.
PLC Control Cabinet & Encoder
In a cold roll forming line, the encoder works with the PLC to provide real-time feedback on material position and speed, ensuring precise feed, synchronized forming, and accurate length control for cutting and punching.
Production speed, product length, and quantity can be set on the control cabinet. The display language can be customized according to customer requirements.
Other Customization Details
The machine comes standard with a blue main color and orange accents. Other colors can be customized free of charge.
The default metal nameplate is Goalon, which can also be customized at no additional cost.
Basic Services
Professional Packing
Machines are packed in plastic film and labeled for easy identification and assembly, and secured inside the container with steel cables.
Installation Guide
Free customized manuals, operationvideos, installationvideos, and remote video supportare provided.
The standard configuration operates at 15–20 m/min. Higher-end configurations can reach 30–40 m/min, and even higher speeds can be customized according to specific production requirements.
Lead times range from 30-50 days post-order, varying by customization level and supplier location. We typically require 45 days for standard machines.
The inline bending machine enables dual-point forming after cutting, eliminating secondary processing and improving production efficiency.
Yes. We are a professional manufacturer that produces both standard market profiles and customized profiles. We can also sign an agreement to ensure that your drawing will not be shared with other parties.
There is no need to worry. Our machines are designed for easy installation and operation.
Before shipment, we will finish the main assembly and testing in our factory. When the machine arrives, you only need to place it in position, connect the power supply, and it can start working.
We will also provide:
detailed installation and operation manuals
machine layout drawings
wiring diagrams
online technical support (video call / photos / videos)
If needed, we can also arrange an engineer to come to your factory to help with installation and training. Many of our customers complete installation smoothly with our online guidance.
30% deposit is paid before production, the balance paid after inspection confrmation, before shipment.
