How does Carsun casters ensure the product quality of casters
Carsun Caster manufacturers ensure product quality through a full-process quality control system, covering the three core links of raw materials, production, and testing. The specific measures are as follows:
- Strict control of raw materials
Establish long-term cooperation with industry-leading suppliers (such as Sinopec's high-transparency environmentally friendly materials); each batch of materials undergoes component analysis + physical performance testing (such as polyurethane wear resistance, steel tensile strength).
Environmental protection and safety certification: Medical casters must passISO and CE certification; food-grade wheel bodies use NSF-certified raw materials (such as Carsun polyurethane wheels).
- Intelligent production process
Mold development: full mold drop-off process ensures hardware accuracy;
Injection molding: Robot automatically picks up parts + wheel core assembly to reduce the risk of manual contamination;
Riveting process: The average daily output of automated riveting equipment exceeds 10,000 pieces (such as automatic assembly of caster brackets).
- Finished product inspection
Process quality inspection: first piece full inspection → production line inspection (every 2 hours) → last piece re-inspection.
Carrying capacity test: static load test (1.5 times the nominal load), dynamic load-bearing walking caster life test, no deformation, no cracking is qualified.
Wear resistance: sandpaper friction wheel surface (GB/T 14687) wear ≤0.1mm/10,000 times
Quietness: decibel meter test at 1 meter (medical scene) ≤35dB
Corrosion resistance: salt spray test for 24 hours (industrial scene). No rust, coating shedding is qualified.
- Quality traceability and improvement
Record the raw material batch number, production equipment number, and operator number for each batch of products; after-sales problems can be traced back to the supply chain link.
- Continuous optimization
Analyze quality inspection data: adjust injection temperature/pressure parameters (reduce bubbles in the wheel body);
Iterate patented technology: such as Carsun Caster's latest patent "A split conductive caster" to strengthen the application of casters in professional fields.
Safety design: anti-fall structure + double brake device (to prevent heavy equipment from sliding).
When choosing a caster wheel manufacturer, give priority to companies that can visit the production line to verify the manufacturer's production capacity and quality inspection on site. Ensure that the caster wheel can run smoothly in later use and its service life is guaranteed.
