The majority of the plastic parts we use in our daily life are made with injection molds. Injection molds are quite complex assemblies with various moving components. Injection molds are not a new invention; they have been used for decades. The plastic injection molding industry has evolved from producing combs and buttons one hundred years ago to producing products for many industries including automotive, medical, aerospace, consumer products, toys, appliances, packaging, and construction. At the same time, the complexity of the molds, the parts as well as the manufacturing process has dramatically increased over the years.
Why the increase in complexity? A Harbour IQ Quarterly Report states for example that, “Vehicle designs are becoming much more complex and the materials utilized in production are shifting to lighter-weight alternatives. This complexity is driving the demand for more tools and molds, which is positive for the industry.” Simply put, as product complexity increases, so go molds, parts and the entire manufacturing process.
