A Trapezoidal Sheet Roll Forming Machine is a regular metal sheet roll former that produces metal roofing sheets or roof panels for both individual and industrial building.
Trapezoidal roofing sheets are the most popular metal roof panels not only for residential buildings but also for commercial or industrial buildings. There are so many different profiles for a variety of applications. People like to use low-profile trapezoidal sheets for elevation and IDT roofing, while for wide-span roofing and load-bearing structures, they tend to select high-profile trapezoidal sheets. In addition, trapezoidal sheets have other names in Africa as industrial trough IT4, IT5, IT6 roof profiles, therefore people can barely find two exactly the same trapezoidal sheet Roll Forming Machine in the markets.
This trapezoidal sheet roll forming machine produces trapezoidal sheets from colour ppgi, gi, aluzinc sheets, and sometimes aluminium steel coils (aluminum roof panels are prefered in Nigeria). Generally, material thickness varies from 0.3 to 0.8mm, and width varies from 914mm to 1250mm. However, in some applications, material thickness can reach up to 1.5mm, like roof deck. Furthermore, in some countries or areas, people use G550 material to make full hard metal roofing sheets.
Sometimes when a client needs to produce trapezoidal sheets with different effective widths with anything else remained the same. In this case, the investment shall be made on only one machine, because a trapezoidal Roof Panel Roll Forming Machine is always adjustable for different feeding widths. This means you can make trapezoidal roof panels with different effective widths from different-width materials. However, a client must need two trapezoidal sheet roll forming machines for manufacturing two panels at the same time.
Just like the regular roof sheet roll former, a trapezoidal sheet roll forming machine typically consists the components as following:
There are different names for trapezoidal sheet roll forming machines in some regions or areas! For example, in Africa, people like to metra roll forming machine, and sometime they give the name industrial trough IT4, IT5, IT6 roof sheet roll forming machineetc.
MAXON designs and builds customized trapezoidal sheet roll forming machines. For instance, some customers ask for G550 metal roofing sheet roll forming machine, some customers may prefer a separate forming stands structure trapezoidal sheet roll forming machine, or some customers may need safety guard on the roll forming machine body etc.

High-Low Temperature Cyclic Test Chamber Common Faults and Solutions
1. High-Low Temperature Cyclic Test Chamber In high temperature test, if the temperature does not reach the test temperature value, the electrical system can be checked and the faults can be eliminated one by one. If the temperature rises very slowly, it is necessary to look at the air circulation system and see if the adjustment baffle of the air circulation is turned on normally. On the contrary, check whether the motor operation of the air circulation is normal. If the temperature overshoots badly, then you need to set the PID setting parameters. If the temperature rises directly, over-temperature protection, then the controller fails and the control instrument must be replaced.
2. If the low temperature fails to reach the target of the test, then you must observe the change of temperature. It is the temperature drop is very slow, or the temperature has a tendency to rebound after the temperature reaches a certain value. The former must check whether it will be before the low temperature test. After drying in the studio, the test chamber is kept dry, and then the test sample is placed in the work chamber. The test sample is placed in the work chamber. The test sample in the work chamber is placed too much, so that the air in the work chamber cannot be sufficiently circulated. After eliminating the above reasons, It is necessary to consider whether it is a fault in the refrigeration system. In this case, it is necessary to ask a manufacturer's professional to perform the repair. The latter phenomenon is caused by the poor use environment of the equipment. The ambient temperature of the equipment and the location of the equipment (the distance between the cabinet and the wall) must meet the requirements (as specified in the operating instructions of the equipment).
3. During the humidity and heat test in the high-low temperature cycle test chamber, the actual humidity will reach 100% or the actual humidity and the target humidity will differ greatly. The value is much lower. The former phenomenon may be caused by dry gauze on the wet ball sensor. It is necessary to check whether the water tank in the wet ball sensor is short of water. The water level in the water tank is automatically controlled by a water level controller. Check whether the water supply system of the water level controller is normal and whether the water level controller is working properly. Another possibility is that the wet ball gauze may cause the gauze to become hard due to the long use time or the purity of the water supply, so that the gauze cannot absorb the moisture and dry, and the above phenomenon can be eliminated only by replacing or cleaning the gauze. The latter phenomenon is mainly because the humidification system is not working. Check the water supply system of the humidification system. Check whether there is a certain amount of water in the water supply system. Control whether the water level of the humidifying boiler water level is normal and whether the water level in the humidifying boiler is normal. If all of the above is normal, then check the electrical control system, which requires professional maintenance personnel to perform the repair.
4. When the high-low temperature cycling test box suddenly fails during the test operation, the control instrument displays a corresponding fault indication prompt and a voice alarm. The operator can quickly check which type of fault belongs to in the troubleshooting section of the operation of the equipment, and the professional can quickly eliminate the fault to ensure the normal operation of the test.
Other environmental test equipment will have other phenomena in use, it must be specific phenomena, specific analysis and exclusion. The environmental testing equipment should also be regularly maintained. The condenser of the refrigeration system should be regularly cleaned. For the moving parts, lubrication should be performed according to the instructions, and the electrical control system should be regularly maintained and inspected. These tasks are indispensable.
