METHOD FOR MODIFYING EXISTING INJECTION MOULD MACHINES TO UTILIZE AN IN-MOULD COATING APPARATUS

摘要

A method of modifying an existing injection molding system so that the syste m can produce articles wherein at least one of the surfaces is coated while th e article remains in the mold. The method includes the steps of providing a dispensing system for a coating composition and modifying an injection moldi ng system to communicate with the dispensing system. Thus, a ~basic~ apparatus is provided, which does not have a control system. Instead, the basic dispense apparatus relies on the molding machine for the control function. The modification can include at least one nozzle to inject and direct the coatin g composition onto at least one surface of the molded article.
