Jiesheng Transmission's Stringent Quality Control Standards
Zhejiang Jiesheng Transmission specializes in the R&D and manufacturing of linear shaft supports and ball screws. We consistently uphold "zero defects" as our core quality control objective. Throughout the entire process-from raw material procurement to finished product delivery-we have established a standardized, traceable inspection system. This ensures every product meets precision requirements, providing stable and reliable transmission components for clients in industrial automation, medical equipment, new energy equipment, and other fields.
Raw Material Inspection
The quality of raw materials directly determines the service life and performance stability of transmission components. Therefore, Jiesheng Transmission enforces a rigorous "Triple Inspection Standard" for all imported bearing steel raw materials, eliminating substandard base materials from entering production at the source:
Basic Compliance Inspection: Professional inspectors conduct comprehensive visual examinations of raw materials, focusing on surface defects like scratches, rust, or dents. Key dimensions such as diameter and length are verified using tools to ensure deviations remain within acceptable limits, immediately rejecting materials failing visual or dimensional standards.
Internal Defect Detection: Employing ultrasonic testing technology, we conduct comprehensive scans to meticulously identify potential internal flaws like cracks, porosity, and inclusions. This ensures uniform and dense internal structure, fundamentally preventing product failures caused by internal defects during processing.
Each batch of approved raw materials generates a dedicated inspection report detailing critical information including batch number, tested items, and data results. This enables full traceability of raw materials, providing customers with clear visibility into the quality at the product's source.
Production Process Inspection
The manufacturing of precision transmission components tolerates no deviation. Jiesheng Transmission implements multiple critical inspection points throughout the entire process-from raw material processing to semi-finished product formation-ensuring "inspection at every operation and documentation at every stage." This guarantees consistent precision compliance from initial processing to final product completion:
Full-process control precision
Real-Time Processing Sampling
Following core operations like precision grinding, thread machining, and surface rustproofing, quality inspectors immediately utilize specialized equipment-including laser diameter gauges, roundness testers, and roughness meters-to conduct inspections. Dimensional accuracy deviations are strictly controlled, and surface finish must meet specified standards. Any deviations prompt immediate adjustment of processing parameters to prevent non-conforming semi-finished products from advancing to subsequent stages.
Multi-dimensional Comprehensive Testing
To meet diverse application requirements, we conduct rust resistance testing (simulating humid environments for specified durations), seal integrity testing (preventing dust/contaminant ingress), and temperature adaptability testing (validating transmission performance under extreme conditions). This ensures products meet the demands of various industrial scenarios.
All test data is recorded in real-time within the company's quality management system, establishing a dedicated "Quality Profile" for each product. This profile details inspection results from every production stage, facilitating future inquiries and traceability.
Final Factory Inspection for Finished Products
Final Inspection Before Shipment To guarantee every delivered product meets order specifications, dedicated personnel conduct dual-verification checks with multi-tiered oversight:
Individual Full-Item Inspection: Quality inspectors meticulously verify critical metrics-precision grade, surface treatment quality, assembly accuracy-against order requirements, ensuring product model, specifications, and performance align perfectly.
Batch Sampling Re-inspection: A proportional sample is drawn from each production batch for repeated testing of critical performance parameters, including precision re-measurement, load testing, and wear inspection. Should any sample fail to meet specifications, the entire batch is returned for rework until all products pass inspection.
For years, Jiesheng Transmission's stringent quality control system has earned recognition from numerous customers. Feedback from a domestic CNC machine tool manufacturer states: "Jiesheng's linear shaft products have operated continuously on our production lines for three years, maintaining precision deviations within design specifications without any failures. This has not only reduced equipment maintenance costs but also minimized downtime losses caused by component issues."
Moving forward, Jiesheng Transmission will continue upgrading its quality control system by introducing more advanced intelligent inspection equipment, optimizing testing procedures and data traceability systems, and further enhancing quality control efficiency and precision. This commitment ensures we deliver more reliable precision transmission components to global customers.
