Our Commitment to Quality Control

Our Quality Control Process

Wheels and casters in a busy commercial or industrial environment must have long-lasting, dependable performance to meet day-to-day material handling needs without breaking or failing. This requires quality, consistency, and repeatability during the manufacturing process.

At RWM Casters, we are committed to quality control and have instituted several testing processes that ensure our wheels and casters are manufactured to the highest possible standards. We use top-quality materials, advanced engineering, and American manufacturing in each product.

The Benefits of Strict Quality Control

Our quality control process starts with top-notch engineering that ensures a superior caster rig with some of the most innovative features in the wheel and caster industry. This is followed by selecting advanced materials inspected and tested in-house and multiple process checks during manufacturing to ensure consistency and quality. Finally, each product line is tested extensively to ensure it meets our rigorous product standards and design specifications.

By enforcing a strict quality control process for each of our products, the consumer can enjoy the following benefits:

• Improved performance: Consistency in the caster manufacturing quality process is essential for the long-term performance of our products. For instance, if the polyurethane on a wheel does not bond or cure properly, it can make the caster harder to roll and compromise the product’s service life. That’s why we go to great lengths to study polyurethane’s material properties and bonding characteristics, ensuring wheel quality assurance on every product.
• Greater Safety: Casters in an industrial environment need to resist failure and perform consistently to move materials safely. This is why features like hardened raceways are important, as softer metals can allow the bearings to wear into the raceway quicker, causing catastrophic failures of the caster and possible injuries as materials shift.
• Customer satisfaction: Rigorous quality testing ensures each component and product slats as long as possible, improving customer satisfaction. Whether it is our 696-hour salt spray testing or our drum testing, we complete extensive real-world testing to ensure our products perform their best.

Our Quality Control Services

We complete several custom tests to guarantee the performance and quality of our products, including:

• Static load testing: Tests each caster to the failure point using 10- to 75-ton hydraulic presses.
• Shock absorber testing: This test uses up to 22,000 pounds of pressure to measure the spring rates and ride heights of shock absorbers.
• Rebound testing: Tests how materials deform and rebound under the intense pressures of a hydraulic press.
• Adhesion test: Measures the force it takes to separate the wheel tread from the wheel core.
• Drop test: A 25-pound weight is dropped onto a caster assembly from various heights to gauge the swivel’s resistance to failures from impacts.
• Drum endurance test: The endurance of the caster bearings is tested by rotating the wheel assembly on a drum at a constant rate of speed for eight hours or until the bearings fail.
• Drum obstacle test: The caster assembly is tested by rotating the wheel on a steel drum, with steel plates of various sizes added as obstacles. This determines how large of an obstacle the wheels can overcome.
• Cart push-pull test: This determines the initial and constant force required to move a cart with our casters up to 2,000 pounds.
• Material hardness testing: Shore-type durometers, Rockwell hardness testers, and chemical composition analysis are used to verify the quality of our materials.
• Brake test ramp: An inclined plane tests our caster brakes’ stopping distance and effectiveness.
