Ensuring Consistent Quality and Reliable Performance
At Bai Ye Industrial Co., Ltd., quality control is integrated into every stage of production.
With over 40 years of manufacturing experience in metal hardware and plastic components, we operate a structured and traceable quality management system to ensure stable product performance, consistent batch quality, and long-term mechanical reliability for global OEM customers.
All raw materials and incoming components are inspected before production to ensure they meet manufacturing requirements and reduce downstream quality risks.
- Steel: Inspection of thickness, hardness, and surface condition
- Plastic resin: Verification of consistency and fundamental material properties
- Bearings, struts, and hardware components: Inspection against technical specifications
During production, quality inspections are carried out at key stages of metal stamping and plastic injection molding to maintain process stability.
- First Article Inspection (FAI): Performed before mass production
- Routine inspection: Dimensional and surface checks conducted during production
- Process adjustments: Modifications based on inspection feedback to minimize production deviations
Finished components are tested in our internal laboratory to evaluate mechanical performance under simulated working conditions.
- Tensile Testing: Evaluates structural strength and load resistance
- Caster Durability Testing: Assesses long-term rolling performance
- Vertical Impact Testing: Verifies shock resistance and structural stability
- Fatigue Testing: Evaluates repeated stress durability
Before shipment, all finished products undergo final inspection to ensure compliance with internal standards and customer requirements.
- Visual inspection: Checks for surface quality and assembly precision
- Functional checks: Testing of movement, load-bearing, and fitment performance
- Batch sampling: Sampling conducted in accordance with AQL (Acceptance Quality Limit) standards
Only products that pass final inspection are approved for packaging and shipment.
Our quality control system is supported by in-house testing equipment used for internal verification of product performance, including:
- Tensile testing equipment
- Caster durability testing system
- Vertical impact testing equipment
- Fatigue testing equipment
Each production batch is recorded and traceable through internal production logs and material tracking systems.
Our quality system is supported by internationally recognized standards, including ISO 9001 and ISO 14001, as well as third-party product testing such as SGS evaluations.
We continuously improve production stability through:
- Manufacturing data analysis
- Equipment and tooling optimization
- Customer feedback integration
Our quality control system helps reduce common procurement risks, including:
- Batch-to-batch quality variation
- Dimensional inconsistency
- Structural performance failure
- Supply chain quality uncertainty
