A form of technology called closed molding enables the production of superior polymer composite parts in a shorter period, with fewer scraps, and with lower volatile gas emissions. Open molding techniques are being replaced by closed molding techniques since the former carry poor qualities and environmental problems. Closed molding techniques allow producers to produce items more quickly and consistently than open molding techniques. The necessity for post-work is decreased because the completed pieces have better surface aesthetics.

  • According to Fact.MR, a market research and competitive intelligence provider, glass fiber composites account for 60% share of the global closed molding composites market in 2023.

Resin transfer molding (RTM) and vacuum infusion process (VIP), two manufacturing techniques used in the production of closed molding composites, are environmentally benign and contribute to a reduction in the atmospheric emissions of volatile organic compounds, such as styrene vapours. Closed molding has several advantages, including improved qualities and higher output, this increases the usage of closed molding composite techniques in various end-use industries, including marine, aerospace, automotive, building, and transportation.

Several factors are likely to support global closed molding composites market growth, such as increasing urbanization across the world, growing popularity of industrial applications, rising number of multinational corporations, enhancement of output through innovative engineering approaches, minimization of energy consumption, and reduction of emission levels.

Fiber-reinforced polymer composites include glass fiber composites. Glass fiber composites are used extensively in the construction, automotive, and aerospace industries and have desirable characteristics including low density, high strength, and ease of processing.

Hybrid glass fiber composites are created by fusing glass fiber with other fibers in a single polymer matrix. In the realm of closed molding composites, hybridization in glass fiber composites sparks fresh concepts.

Glass fiber-reinforced plastic (GFRP) composites are increasingly in demand due to the development of new, high-quality materials. In both established and developing countries, rapid urbanization, and infrastructure development are driving sales of closed molding composites.

What’s Driving the Sales of Closed Molding Composites Across the World?

Usage of closed molding composites in various applications is influenced by several variables, including the expanding need for lightweight components in the transportation industry, the move towards renewable energy sources, and increased material recycling.

“Aerospace & Defense Industries Taking Flight with Closed Molding Composites”

Compared to other composites, closed molding composites have various advantages including higher rigidity, electrical conductivity, temperature performance, higher tensile strength, higher chemical resistance, and lighter weight. They are highly utilized in aerospace and defense applications because of these qualities.

In comparison to a majority of woods and metals, composites are lightweight. In the military and aerospace industries, advanced composite materials have a long history. In thermal, chemical, mechanical, and ballistic applications in military aviation, there is a high use of composite materials. These applications specifically make use of fiber-reinforced plastic composites.

“Superior Surface Polish & Non-corrosive Qualities Driving Demand for Closed-molded Composites in Several End-use Industries”

Applications such as construction, transportation, and electrical & electronics are seeing an increase in the demand for closed molding composites produced by the compression molding method since these industries need the superior surface polish and non-corrosive qualities that these composites offer. Composites are effective insulators because they do not readily conduct heat or cold. When further protection from severe weather is required, they are employed in the building sector in panels, doors, and windows.

“Closed Molding Composites Catch Wind - Driving Growth in Renewable Energy Industry”

Renewable energy is becoming widely popular. The closed molding composite sale is expected to be driven by the wind energy industry globally during the forecast period. This is because there is a growing demand for long, lightweight wind turbine blades, which opens up opportunities for carbon fiber composites.

“Carbon Fiber Taking Driver's Seat in 3D-Printed Car Parts”

High adoption of more environmentally friendly building materials is a result of the widespread implementation of strict environmental regulations in countries that are both developed and developing. The benefits of carbon fibers and the related composites are their lower weights and improved fuel efficiency. As a result, the market for luxury and sports cars is driving up demand for activated carbon fibers.

For the production of 3D-printed car parts, carbon fiber is widely used in the automotive sector. The filament is more rigid and robust due to carbon fiber, which is incredibly powerful. As a result, the 3D-printed items are expected to be significantly lighter and more dimensionally stable as the fiber will assist in preventing the part from shrinking as it cools.

Which Challenges are Encountered by Closed Molding Composite Producers?

“High Initial Investments & Raw Materials Costs”

The closed molding process requires specialized equipment and tools, which can be costly to acquire and maintain. This can be a significant barrier to entry for smaller manufacturers who may not have the financial resources to invest in the required equipment.

Closed molding requires specialized raw materials, such as pre-impregnated fibers or resin transfer materials, which may not be readily available in all regions. In the automotive business, only luxury cars use carbon fiber composites (which are very costly), including carbon fiber tapes. Thus, the high cost of raw materials needed for processing and production is also hampering the closed molding composites market growth.

“Few Quality Control Challenges”

Closed molding processes require more precise control over the manufacturing environment, including temperature, humidity, and pressure. This can be difficult to achieve consistently, which may lead to variations in product quality, further hampering sales of closed molding composites.
