Ya. Believe Industry offers custom design services, engineering equipment based on your precise profile specifications, material requirements, and production goals. COPRA® software is used to optimize roll flower designs, ensuring forming accuracy and production efficiency.

Ya. Believe Industry delivers turnkey production line solutions, not just individual machines. A complete line typically includes: uncoiler → leveler → servo feeder → punch press → roll forming machine → cutting system → output table. All equipment is integrated and tested as a complete system before shipment, ensuring seamless operation upon installation.

Standard machines are pre-designed for common profiles (e.g., standard C/Z purlins, popular roofing panels) with proven configurations, shorter lead times, and lower cost. Custom machines are engineered from scratch for unique profile cross-sections, special material requirements, or non-standard production speeds. Both types receive the same quality of manufacturing and testing.

Believe Industry offers multiple cutting solutions tailored to profile type and production needs:

• Flying shear (hydraulic) — for thicker materials and heavy profiles, cuts without stopping the line
• Flying saw (circular) — clean, burr-free cuts for thinner materials and closed profiles
• Servo-driven cut-to-length — high precision ±0.5mm length tolerance
• Pre-cut + roll forming — material cut before entering the mill, suitable for some specific applications

Yes, in many cases. Some machines are designed as combined / duplex type, such as C/Z purlin interchangeable machines that can switch between C and Z profiles by simply adjusting spacers or swapping roller sets. For more diverse profiles, quick-change roller cassette systems are available, allowing rapid changeover between different product runs with minimal downtime.

Cold roll forming is a process of continuously bending metal strip into desired cross-sectional shapes. The metal coil passes through a series of arranged forming roll stands, progressively bending into the target profile. The entire process occurs at room temperature without heating, making it ideal for high-efficiency, high-volume forming of various metal sheets.

Believe Industry uses the industry-leading COPRA® software for roll flower optimization design. Finite element simulation analyzes stress and strain during the forming process, ensuring rational pass distribution and minimizing material springback and forming defects.

Integrated Siemens / Mitsubishi PLC control system featuring:

• Touch screen HMI (Human-Machine Interface)
• Servo-driven fixed-length cutting
• Real-time production data monitoring and recording
• Remote diagnostics and fault alarms

Depending on the product and configuration, line speed typically ranges from 15-60 m/min. High-speed production lines can achieve even higher speeds. Actual speed depends on profile complexity, material thickness, and tolerance requirements.

Supports cold roll forming of various metals:

• Carbon steel (cold-rolled / hot-rolled / galvanized)
• Stainless steel
• Aluminum alloy
• Pre-painted / color-coated steel
• High-strength steel (requires special roll design)

Material thickness typically ranges from 0.3mm to 8mm, depending on the specific machine model.

Forming rollers are made from Cr12 / Cr12MoV / D2 premium die steel, quenched to HRC 58-62 hardness. Surfaces can be hard-chrome plated for enhanced wear resistance. Under normal maintenance, roller life can reach millions of meters of forming length.

Believe Industry equipment achieves precision tolerances:

• Cross-section dimension: ±0.2mm to ±0.5mm (depending on profile complexity)
• Cut-to-length accuracy: ±0.5mm (servo-driven cutting)
• Kelurusan: ≤1mm/meter
• Twist: ≤0.5°/meter

Tighter tolerances can be achieved with special design and configuration for demanding applications.

Cold roll forming offers distinct advantages over stamping, press braking, and extrusion:

• vs. Stamping — continuous production vs. batch; much higher throughput for long profiles
• vs. Press Braking — consistent quality across entire length; no manual repositioning; far faster production speed
• vs. Hot Extrusion — no heating required; lower energy cost; better surface finish; suitable for coated materials
• vs. Roll Forming — optimized progressive forming reduces material stress and springback

Cold roll forming is the most cost-effective method for producing long, consistent cross-section metal profiles at high volume.

Power consumption depends on machine size and profile complexity:

• Light-duty lines (thin gauge, simple profiles): 15–30 kW total installed power
• Medium-duty lines (standard purlins, roofing panels): 30–60 kW total
• Heavy-duty lines (thick gauge, complex sections): 60–120 kW total

Actual running consumption is typically 60-70% of installed power. Servo-driven lines offer better energy efficiency compared to conventional hydraulic systems.

The number of forming passes depends on profile complexity and material thickness:

• Simple profiles (e.g., straight bends, angle sections): 12–18 passes
• Standard profiles (e.g., C/Z purlins, roofing panels): 18–24 passes
• Complex profiles (e.g., closed sections, multi-bend shapes): 24–36+ passes

More passes allow gentler, more progressive forming, which reduces springback and improves dimensional accuracy. Believe Industry's COPRA® simulation determines the optimal number of passes for each design.
