Competition Bumper Plates are primarily used for competition in High-Level Training Facilities, for example, Used by elite athletes and training centers focusing on competitive weightlifting and powerlifting. They differ from standard weight plates in several key ways, focusing on precision, durability, and consistent performance. Key Characteristics of Competition Rubber Weight Plates including precise Weight: This is the most critical aspect. Competition plates must adhere to strict weight tolerances, typically within +/- 0.25% of their stated weight. This accuracy is essential for fair competition. Standard plates often have looser tolerances; consistent Diameter: Plates must have a standardized diameter, typically 450mm (17.72 inches) for the larger plates (25kg, 20kg, 15kg, 10kg) and sometimes slightly smaller for smaller denominations. This ensures uniform bar height during lifts, regardless of weight. And it's color-Coded: Competition plates are typically color-coded according to their weight, following a standardized system (often IWF standards). This makes it easy for loaders to quickly identify and add the correct plates. Common color coding includes: Red: 25 kg, Blue: 20 kg, Yellow: 15 kg, Green: 10 kg.
We have 3 close rubber mixer and 3 open rubber mixer located in three separate workshops. Colored rubber and black rubber are mixed in separate equipment, and this production method ensures the color purity and quality stability of colored products. After mixing each batch of rubber, the technicians will test the specimen with a rotorless vulcanizer to confirm the vulcanization time and temperature. We have 40 vulcanizing machines for barbell plates and hexagonal dumbbells, including 10 300-ton evacuation vulcanizers. Stable machine performance and a large number of machines allow us to deliver orders quickly. The configuration of ancillary equipment, including preform machines and rubber cutting machines, is of great help in improving production efficiency. Each weighing machine is regularly calibrated by a third-party company to ensure that the ratios are rigorous and that the weight tolerances of the barbell pieces are controlled.
Our professional quality control system starts with materials purchasing. We established our materials supplying chain in 2006 while our first factory came into being. They are DJSilicone, Hongyun and other reliable suppliers in the line. Their high trade reputation coincides with our idea of producing high-quality products for our customers. We are able to test our materials on site and give them our feedback. Besides, we always have each lot of raw materials trucked to our warehouse recorded after the test. If we found anything wrong, our quality department of our factory will timely come back to our suppliers on the same day and figured out an efficient solution to make sure that our production goes well. We put our lab into use in 2012. Our Chief Engineer, Mr. Sun retired from the Northwest Rubber&Plastics Research And Design Institute of China, has got involved in more than 20 major projects since 2012. The inspection report is very important for stocking raw materials and products delivery. We guarantee that we never make and deliver poor quality to any one of our new and existing customers. Raw materials test, design control, document control, prototype, calibration, control of non-confirming sample and the quality records, we have a very strict and professional system to operate. We do drop test for our rubber bumper plates. This step is to make sure that the finished bumper plates can reach a high rate of drop times. Meanwhile, we put samples of our rubber tiles on the bearing surface, so it can also tell the quality of our rubber tiles when we operate the drop test over our bumper plates. Rubber tiles are made of recycled rubber materials. With a safe materials purchasing chain, we do not worry of the impurities inside. When the raw material supplying chain is correct, the rest job for us is to make high quality products at competitive price. Quality inspection & Testing is always the most important procedure in our quality control. Testing devices are very crucial to quality, but we always believe that our professional workers with enthusiasm is the key for us to get the trust from you.
