Monitoring the Injection Molding Process to Improve Quality and Lower Costs

When it comes to plastics applications, cars are rarely the first products that come to mind. However, with modern vehicles containing 1,000 to 1,500 plastic parts — including dashboards, control elements, clips, trim parts, brackets, door panels, bumpers, and radiator grilles — the material is more important for mobility than we might assume. Some of these plastic parts are relevant for the drivers’ safety: for instance, airbag covers must open correctly in an accident and seat belt guides and retractors could cause severe injuries if they break or deform under load. Their quality is vital. At the same time however, cost pressure and new regulations — for instance regarding an increased use of recycled materials that is under way in the European Union — pose new challenges, especially in plastic injection molding. Digital solutions for measurement technology help control and stabilize the complex process and may even lead to increased product quality despite tougher conditions.
