Aim of this project is to provide a turnkey solution to achieve the matrix of radiator i.e. radiator core. Radiator core consists of uniformly spaced tubes and fins placed within the spaces between adjacent tubes. Conventional methods turn out to be unsuitable for this function. This paper is concerned about assembly machine for radiator core for low batch production. As demand for the radiators is low. Therefore, automation cannot be a choice because of the price constraints. Eventually, best choice is to have manually operated machine. The machine consists of hydraulic actuators for a pressing operation, brackets for cylinder and core support. For complete design of assembly machine, design of these crucial components is need to be done as explained further in the paper
