Injection molding involves the manufacturing of plastic products by injecting molten materials into a mold, where it is melted, cooled, and solidified to form the final product. Thermoplastic as well as thermosetting injection molded plastics are used for manufacturing several parts and components for various applications. Injection molded plastics are used in the production of complex and intricate-shaped parts to ensure precision and minimize wastage. Hence, injection molded plastics are used in manufacturing automotive components, interior wrapping, and numerous assembly parts. It is chiefly used in packaging applications to manufacture packaging parts and components to increase the aesthetic value and consumer friendliness of the packaging products. Popularity of injection molded plastics in building and construction applications is increasing, owing to their strength, durability, and texture of the injection molded plastic parts. In building and construction, these plastic parts or components are mainly used for piping systems, insulations, wall boards, and roofing purposes among others. Healthcare industry is anticipated to be the fastest growing application segment for injection molded plastic industry during the forecast period. Moreover, blood sample analysis cuvettes, pregnancy test devices, housings for needles, medical devices components are the other application areas of these plastics, owing to their light weight, cost-effectiveness, and easy sterilizability.
Injection molded plastics are used in automated processes to reduce the manufacturing cost. It also reduces the waste production in production process. Factors such as low production waste and faster production process would augment the growth of the injection molded plastic market. In addition, the process has ability to use different types of raw materials simultaneously to manufacture plastic parts. Furthermore, technological advancements in injection molding process, where robots are deployed for performing different operations, such as finishing and assembling injection molded parts and loading components into the injection molding, would foster the growth of the market. Therefore, the world injection molded plastic market is estimated to reach US$162.06 bln by 2020, registering a CAGR of 4.9% during 2014–2020, as per Allied Market Research. However, high initial tooling cost and volatile prices of crude oil would hamper the growth of the market. Among the materials, polypropylene is the most preferred raw material, owing to its ease of molding, electrical insulating properties, heat resistance, and low cost. In 2014, polypropylene accounted for about 39% share of this market. Furthermore, on the basis of end-users, the market is segmented into packaging, automotive, consumer goods & electronics, building & construction, and medical disposal. In 2014, packaging was the leading application segment for injection molding, accounting for around 37% of the overall market share. The growing demand for rigid packaging material in industrial and consumer packaging applications would foster demand in the packaging industry. In 2014, North America was the leading market for injection molded plastic, accounting for around 35% of the global market share. Asia-Pacific and LAMEA have witnessed large-scale demand on account of its growing demand in building & construction sector, consumer appliances, and automotive industries. Hence, Asia-Pacific is expected to grow at a CAGR of 6.8% during 2014–2020.

As per mrrse.com, out of all the applications, packaging dominates the global molded plastics market and is expected to retain its dominance in the coming few years. Demand in this segment will be driven by the growing usage of plastics for the purpose of packaging of food and beverages, electronic equipment, surgical equipment, and others. Demand in the electronics and consumables segment is expected to be the highest in the next few years. The robust growth rate of this segment can be attributed to increasing demand for electronic goods such as televisions, laptops, and mobile phones. Furthermore, the growing demand for electronics is also fuelling the demand for molded plastics that are required in making internal and external electronic parts. According to analysts, the consumables and electronics segment is likely to account for a share of 30% in the overall molded plastics demand by 2019. Geographically, Asia Pacific was leading the global molded plastics market in 2012, with a share of over 35%. This position was mainly due to the growing demand from various industries in the region such as electronics, automotive, and packaging. As economies such as India, China, and Japan emerge with a strong manufacturing base, Asia Pacific is expected to remain in the top position in the global molded plastics market. Furthermore, rising per capita income, which is allowing consumers to purchase automobiles and electronics, will also drive this region’s growth. Lastly, the ever-increasing demand for packaged food and beverages will also make its generous contribution to the demand for molded plastics in the Asia Pacific region.
