Study Based On Orthogonal Test For The Welding Performance Of Plastic Fuel Tank

With the development of the automobile industry,people pay more attention to the light weight and safety,and promote the application of plastics in automobile parts and components.Plastics are more and more widely used in automotive fuel system,and the fuel tank is the key part of the automobile fuel supply system,and the model of the application of plastics in the fuel system.At present,the connection of the plastic fuel tank parts of our company mainly rely on hot melt welding,but the welding efficiency is low,the quality is not stable,the rejection rate is high,so it is the purpose and significance of this research to improve the production efficiency and reduce the cost.For hot plate welding,the main factors that affect the welding quality are seven: hot plate temperature,matching time,heating time,welding time,matching pressure,heating pressure,welding pressure.To improve the production efficiency and improve the quality of the product,the welding parameters are studied,and the method of orthogonal test is used to study the welding parameters.Through experiments,this paper the welding process parameters were determined,and formulate the seven factors and three levels of orthogonal experiment,through a large number of tests and collect test results,application of the test results were analyzed on the welding process of optimization calculation,the welding parameters optimization model,and an experiment is carried out to verify,formed a production company debugging can be used during the optimization model.The model can be used to find the optimal process parameters,which can solve the problems in the process of plant production,and improve the efficiency of the production.
