For many years, metal has been the standard material for industrial components. While metal continues to have its place, advancements in engineered plastics have made them an increasingly popular choice for manufacturers across food processing, dairy, automation, OEM manufacturing, paper mills, and other industrial environments.
Modern industrial plastics offer several advantages over traditional metal components, including reduced weight, corrosion resistance, improved wear characteristics, quieter operation, and lower long term maintenance costs. Choosing the right material for the application can improve equipment performance while extending component life.
At Royal Custom Plastics, we help customers evaluate their applications and determine when plastic components provide a better long term solution than metal.
Reduced Weight Improves Equipment Performance
One of the biggest advantages of plastic over metal is weight. Plastic components are significantly lighter, which reduces the overall load placed on machinery and moving equipment. Lighter parts can improve efficiency in automation systems by reducing strain on motors, bearings, and drive systems. They are also easier to install, remove, and replace during routine maintenance, helping minimize downtime and improve workplace safety. For applications with repeated movement, reducing unnecessary weight can contribute to smoother operation and increased equipment longevity.
Corrosion Resistance Extends Component Life
Unlike metal, plastics do not rust or corrode when exposed to moisture, chemicals, or harsh cleaning solutions. This makes them an excellent choice for food processing, dairy production, paper mills, and other environments where equipment is regularly washed down or exposed to humidity. Corrosion can weaken metal components, affect performance, and require frequent replacement. Plastic materials maintain their integrity under these conditions, providing a longer service life and more consistent performance. Selecting corrosion resistant plastics also helps reduce maintenance requirements over time.
Excellent Wear Characteristics
Many engineered plastics are designed to withstand continuous friction, movement, and impact. Materials such as UHMW and Acetal offer outstanding wear resistance while maintaining dimensional stability throughout their service life. In many industrial applications, plastic components experience less friction than metal, allowing equipment to operate more efficiently. Lower friction also reduces wear on surrounding components, helping extend the life of the entire system. Proper material selection ensures components continue performing reliably even in demanding operating environments.
Quieter Equipment Operation
Noise is often an overlooked factor in industrial environments. Metal components contacting other metal surfaces can create excessive vibration and operating noise. Plastic components naturally absorb vibration and reduce friction, resulting in quieter equipment operation. This not only creates a more comfortable work environment but can also reduce stress on machinery by minimizing vibration during operation. For conveyor systems, automation equipment, and material handling applications, quieter performance is often an added benefit of switching to engineered plastics.
Lower Long Term Maintenance Costs
Although replacing a metal component with plastic may seem like a simple material change, the long term benefits often extend much further. Plastic components typically require less maintenance because they resist corrosion, reduce wear, and perform reliably under challenging conditions. Longer lasting parts mean fewer replacements, less downtime, and lower maintenance costs throughout the life of the equipment. When combined with proper design and precision machining, plastic components can significantly improve operational efficiency. Royal Custom Plastics frequently works with customers to redesign existing metal parts using engineered plastics that better suit the application and reduce ongoing maintenance.
Choosing the Right Material for the Application
Not every application requires metal, and not every application is best suited for plastic. Understanding the operating environment, performance requirements, and maintenance goals is essential when selecting the right material. Our team works closely with customers to evaluate each application and recommend plastics that provide the best balance of strength, wear resistance, chemical resistance, and long term durability. Whether replacing an existing metal component or developing a new design, we help ensure the material matches the demands of the job.
