Quality Control System

Hengchangtai has built a comprehensive, closed‑loop end‑to‑end quality control system, implementing standardized control mechanisms across the full value chain of modified plastics, covering R&D, production, testing and delivery. Centered on standardized quality management, we precisely adapt to production requirements for various customized materials and provide customers with stable and reliable new‑material solutions.

We are fully dedicated to fostering a quality‑driven corporate culture. Quality is consistently treated as the cornerstone of corporate development and the foundation of our reputation. Upholding the philosophy of continuous improvement, we keep track of evolving material standards across downstream industries, continuously refine quality control procedures, and satisfy customers’ diversified demands for high‑quality products.

Our core quality policy — Customer First, Quality First, Continuous Innovation, Continuous Improvement — serves as the guiding principle for company‑wide quality practices. While advancing innovation and R&D, we strictly abide by quality criteria to achieve synchronized progress in technological advancement and product stability.

Strictly aligned with authoritative industry specifications, we operate a standardized quality management system and implement meticulous end‑to‑end process control. Our control scope covers all phases including raw‑material intake, modification production, finished‑product testing, warehousing and shipment. Proactive quality risk prevention helps eliminate quality non‑conformities at the source.

Backed by systematic and standardized quality management practices, Hengchangtai realizes full‑process traceability, controllability and optimizability over production. Supported by stringent inspection regimes, we steadily deliver premium modified‑plastic products and reinforce our core competitiveness in the market.

Certifications & Compliance System

Hengchangtai upholds a standardized sustainable‑development philosophy, with a full‑fledged certification system serving as the cornerstone for our technological R&D, production control and market‑oriented services. We focus on modified engineering plastics and actively advance industry‑university‑research cooperation with South China University of Technology and Shenzhen University in polymer chemistry. Empowered by scientific research, we promote the execution of standard frameworks and realize mutual synergy between technological innovation and standardized management.

We have set up a sound quality‑management framework and been granted ISO 9001:2015 Quality Management System and IATF 16949:2016 Automotive Quality Management System certifications. The dual‑system deployment enforces strict full‑process control covering raw‑material screening, formulation R&D, modification production and finished‑product testing, which fully satisfies strict supply‑chain access requirements from high‑demand downstream clients in automotive components, electronics and electrical sectors.

For environmental protection as well as occupational health & safety, we follow green‑manufacturing guidelines and hold ISO 14000 Environmental Management System and ISO 45001 Occupational Health and Safety Management System certifications. We keep optimizing energy‑consumption governance, pollutant treatment and workshop safety administration to build a safe, eco‑friendly modern‑production base for modified plastics, putting the green‑new‑material development concept into practice.

To satisfy hazardous‑substance control needs from the electronics sector, we have obtained HSPM (Hazardous Substance Process Management) System certification. Systematic hazardous‑substance control workflows are implemented to prevent risks of heavy metals and restricted chemicals at source. This guarantees our modified‑plastic products conform to global eco‑regulations for electronic goods and meet procurement specifications of domestic and overseas E&E customers.

Meanwhile, we have established formal mechanisms for innovation protection and acquired Intellectual Property Management System certification. Under standardized IP administration, we coordinate patent mining, technical‑achievement protection and R&D achievement commercialization, so as to consolidate our proprietary core‑technology strengths in modified‑engineering‑plastic formulations and processing techniques.

To adapt to global market‑access rules, Hengchangtai’s modified‑plastic products have gained numerous authoritative domestic and international product certifications including CQC, RoHS, REACH and UL. Such diversified certification portfolios support product deployment across multiple fields: home appliances, automobiles, food‑contact articles and electronic components.

Multi‑level system certifications and product certifications complement each other and constitute Hengchangtai’s complete compliance assurance system. Guided by relevant standards, we continuously standardize R&D, manufacturing and supply‑chain management. Supported by industry‑university‑research innovation strengths and standardized control capabilities, we deliver compliant, reliable and stable modified‑engineering‑plastic solutions for clients at home and abroad.
