Incomplete curing of sheet molding compounds (SMC) as well as the post-curing and out gassing during the industrial coating process are the two main reasons for the coating problems of SMC Class-A automotive parts. Furthermore, their surface properties as contact angles and surface roughness strongly depend on processing parameters of thermal curing and coating as well as used cleaning and pickling methods. Consequently, cost and energy intensive additional process steps are used in the automotive industry in order to reduce or avoid above mentioned problems during the industrial coating process of SMC-Class-A automotive parts. A cost efficient robust procedure is required in order to overcome these disadvantages as well as to fulfil the requirements of industrial coating processes. Based on electron beam curing and surface functionalization by low energy electrons a novel pre-treatment procedure was developed and tested. For this purpose, two different compact electron emitters have been coupled to a robot in order to validate this novel inline pre-treatment procedure. In one additional step, post-curing and surface functionalization of the three dimensional SMC-parts is achieved. Presently, this novel pre-coating technology is tested for different SMC-parts.
