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 system can produce articles wherein at least one of the surfaces is coated while the article remains in the mold. The method includes the steps of providing a dispensing system for a coating composition and modifying an injection molding 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 coating composition onto at least one surface of the molded article.
