Perfil
This roll forming machine is designed to manufacture drainage grates in two different sizes. The profiles are 1.5 mm thick and made from high-quality galvanized steel. These gratings provide drainage, slip resistance, load support, and odor control, making them ideal for showers and floor drain applications. The machine can operate at speeds of up to 12 meters per minute.
Each machine can be tailored to the client’s specifications and budget. Before shipment, every unit undergoes thorough testing to ensure it meets production standards and delivers stable performance over time.
The production line and parameters of each part
（Parameter table）
Detailed description of each part of the production line
Decoiler: At the start of the production line, there is an integrated decoiler and leveling unit. The decoiler features a pressure arm to prevent the steel coil from uncoiling suddenly, reducing the risk of injury to operators. This mechanism also secures the coil in place, ensuring safe operation.
Adjacent to the decoiler is the leveling section, which consists of 7 leveling rollers and 4 pressure rollers. This process releases internal stresses in the steel coil and produces a more uniform surface, readying the material for the punching stage.
Using a combined decoiler and leveler provides space efficiency compared to having them as separate machines. While independent units need 3 to 4 meters of clearance between them, the integrated system reduces this distance and streamlines the production line.
Limiter: A limit sensor is installed between the decoiler and the punch press. It is linked to the punching machine and functions to detect the position of the steel strip.
Punch Press: In the punching area, a 160-ton press is used, capable of performing 35 to 50 strokes per minute. This press is faster than a standard hydraulic press, improving the overall efficiency of the production line. Each product size requires its own set of molds, meaning a total of 2 sets are provided. When switching production sizes, the appropriate molds must be replaced in the press.
The press is also equipped with a servo motor feeder, ensuring accurate positioning during punching and rapid material feeding. Control of the punch press is handled through a separate electrical cabinet. A detailed manual is provided to guide the customer through proper operation of the machine.
Limiter: A frame equipped with limit sensors is positioned between the punch press and the roll former. The frame houses two sensors: the upper one is linked to the roll former and stops the machine if the steel strip comes into contact, signaling that it is running too fast. The lower sensor is connected to the punch press and halts its operation if the strip touches it, indicating excessive speed.
This system helps regulate the speed of different sections of the production line, ensuring safe operation and protecting the equipment from potential damage.
Roll forming machine: The roll former is built with a cast iron support frame and transmits power via gearboxes, providing a highly stable and long-lasting structure. To accommodate two different sizes, the machine comes with 2 sets of rollers (cassettes). When switching production sizes, the corresponding cassette must be replaced—a process that typically takes 30 to 60 minutes but becomes quicker with experience.
Additionally, the rollers are chrome-plated to enhance corrosion resistance and prolong their service life, ensuring reliable performance over time.
Flying saw cut: In the cutting area, a flying saw system is employed. Coolant is applied during cutting to keep the blade cool and reduce the scattering of metal chips. Flying cutting allows the roll former to keep running while the profile is being cut, improving overall production efficiency.
A servo motor controls the movement of the cutting section to ensure precise tracking. Prior to cutting, the profile passes through a straightener to guarantee straightness. The resulting cut pieces are clean and free of burrs, ready for immediate use.
Spare parts box / Installation video / Manual: We provide our clients with a comprehensive set of spare parts, covering all critical components to allow fast replacements if any part of the machine is damaged. To make sure the production line is properly set up upon delivery, we include a step-by-step installation video. In addition, a detailed user manual is provided in English and other languages as required, giving operators all the necessary information for efficient and safe machine operation.
Our company operates a factory in China, along with an office and showroom in Mexico. Our team of engineers, fluent in both English and Spanish, offers professional after-sales support, addressing the common challenge of limited service when purchasing machinery directly from China.
