Quality assurance is a process that ensures that the products meet the specifications and expectations of the customers. Quality assurance in insert mold processes involves several steps, such as: selecting high-quality materials for the inserts and the plastic; designing and testing the mold to ensure proper fit and alignment of the inserts; controlling and monitoring the injection parameters to ensure consistent filling and bonding of the plastic; inspecting and measuring the molded parts to verify their dimensions and appearance; and performing quality tests to check their functionality and performance.
