Trailers are used for transporting goods and equipments. Trailer manufacturing process requires good quality control and engineering knowledge. Trailer manufacturers throughout Melbourne build trailers via heavy vehicle manufacturing process. There are various steps which are involved in manufacturing of trailers.
Trailer manufacturing starts with the process of designing of the trailer. The design needs to be 100 percent accurate. Latest 3D software technology can be used for this purpose. Each part of the design needs to be dimensionally correct and must meet the requirements of the customers. Simulation software can be used to simulate loadings, deflection and stress levels on parts before they are produced.
The next step after the design has been finalised and approved is to cut the steel parts using state of art machines. Very high accuracy is utilised for this purpose and the process must be repeatable with other parts. Depending on the design chassis rails can be fabricated which are either flat bed or stripped plate flanges. Machines can be used to make chassis rails. All the process needs to be according to industry standards. Every part must be consistent and strong.
The next step is trailer fabrication where raw materials are used to cut size the chassis and body assembly can begin. All parts which are assembled must be labelled for identification. Fabrication must be done to strict standards and quality procedures. Each assembly part must be checked and signed off.
Now the components need to be proceeded to abrasive blast and painting. After doing abrasive blasting the parts must be sent for painting. Primer must be applied and then allowed to dry. It must then be sand smoothed and sealed for top coat. The parts are then painted with the required colours and finished. After inspection the parts are ready for assembly.
Painting can also be done after assembling the parts. In the next stage the parts are fitted and assembled. This includes axles, brake system, suspension, hydraulics, mud guard, lights and others. The trailers are tested to ensure that the trailer is working properly and there are no leaks in the system. Bolt tensions must be checked and signed off. The trailer is now ready for licensing and it can be delivered to the customers.
