Automotive the Fastest Growing Market for Injection Molding
Injection molding is the most important processing method for mass production of plastic parts: Worldwide, almost 55 million tonnes of plastics are liquefied every year, then injected into various molds, and after cooling removed as a finished product. The market research company Ceresana has published a study on the world market for plastics for injection molding.
In 2015, about 54% of the plastics used for injection molding were used in the region Asia-Pacific; North America and Western Europe followed with market shares of 15.4% and 14.3%. The most important sales market for injection molded products is the packaging industry which mainly protects food with these: containers, cans, mugs, bowls, boxes, and closures of any kind. Packaging made of plastics offers numerous advantages over other materials. Besides their low weight and a reduced fracture susceptibility, plastic packaging can profit in some segments from its transparency or resistance against chemicals. The second largest - and fastest growing - sales market is the transportation industry which for example uses injection molding for dashboards, bumpers, and headlights. Analysts of Ceresana expect global demand in this application area to increase by 3.7% per year until 2023.
The present study analyzes the market for plastics used for injection molding, particularly for the plastic types polypropylene (PP), polyethylene (LDPE, LLDPE, HDPE), polyamide (PA), acrylonitrile butadiene styrene (ABS), polystyrene (PS), polycarbonate (PC), and other products. Polypropylene (PP) is the most important plastic type for injection molding: Over the past eight years, global demand for products made of PP rose by an average of 3.8% per year. The second most important plastic type for injection molding is polyethylene with a market share of 20%. However, there are significant differences within the particular sales markets. For example, the share of demand for polypropylene in the segment packaging amounts to almost 70% while its share in the construction industry only totals 12%.
