Rubber molding processes support sustainability by minimizing material waste and using energy-efficient technologies like cold runner systems and precise temperature control. Unlike other fabrication methods, molding can integrate recycled content and minimize hazardous emissions. Here are some of the environmental impacts of rubber molding versus other processes:
Material Efficiency
Precision molding processes produce rubber components with minimal waste material compared to machining processes. Processes such as transfer molding form the component with an accurate amount of rubber each time. Automated mixing and molding eliminate material overages that are experienced in manual processes. Molded components exit the press ready for assembly, without the need for further trimming or shaping, which supports material conservation.
Recycling Options
Because rubber molding facilities utilize thermoplastic elastomers (TPEs), they can recycle old components or scrap materials. TPEs provide the performance of vulcanized rubber but can also be completely recycled to form new components. Recycled rubber can also be used in molding for base compounds, reducing manufacturers’ reliance on virgin materials. Recycling materials into new molded rubber components makes this manufacturing process a sustainable practice.
Product Durability
Molded rubber components withstand wear from impacts, chemicals, water, and exposure to UV radiation. Molded components can also handle heat-intensive processes and extensive vibration that harm other materials. The durability of these products increases their lifespan, reducing the need for frequent replacements. Durable molded pieces require the procurement of fewer resources in the long term than less resilient plastics and blends. The increased service life of molded rubber parts supports sustainability standards.
Reduced Emissions
Unlike metal casting or aerated concrete, rubber molding does not involve extreme heat levels. This minimizes the release of volatile organic compounds and hazardous air pollutants associated with combustion. High-quality molds reduce manufacturers’ exposure to toxins found in lead casting, and the inert final parts prevent chemicals from leaching into the environment. These cleaner processes allow manufacturers to produce molded components while protecting air and water quality.
Eco-Friendly Options
Molding can utilize environmentally friendly raw materials such as natural latex, which is tapped from the rubber tree, for manufacturing purposes. Plant oils replace petroleum feedstocks in advanced bio-based polyols, reducing dependence on fossil fuels. Recycled rubber content can also be enhanced by sustainable chemical additives that allow reclaimed rubber to be reintegrated into new molded products without compromising performance.
Reduced Waste
Molding offers an efficient solution for producing complete products that don’t need waste-intensive finishing. Rubber parts emerge from their molds fully finished and ready for use or assembly. By eliminating additional manufacturing processes, like water jet machining and routing, molding prevents post-fabrication scrap generation and reduces resource usage. This reduces shop waste output and disposal requirements.
