Huaxing intelligent spring design and manufacturing system

CATALOG’s primary spring force‑measurement systems are computer‑controlled, fully automated units. Originally, these machines only required manual entry of test parameters before leaving the factory to automatically measure key spring characteristics such as free length, stiffness, and force.

In 2017, CATALOG collaborated closely with the equipment manufacturer—Jinan Kailedi—to customize data interfaces and drivers, enabling these testers to directly read the design parameters and tolerance requirements for each spring from the HuaXing platform database. This integration automates the measurement of critical parameters including free length, spring rate, force value, and force‑displacement curves. The system now performs closed‑loop, fully automated operation across five stages: parameter import, test execution, data capture, quality judgment, and report generation, thereby virtually eliminating human influence or interference on test results.

Spring defects can often stem from misinterpretation of technical requirements by production or inspection staff—especially when drawings are complex or in a foreign language. At CATALOG, from the initial inquiry stage, experienced engineers thoroughly review every customer drawing and specification using the design module of the “Huaxia Xing Intelligent Spring Design and Manufacturing Platform.” They validate the spring design and promptly communicate any discrepancies with the customer.

Once confirmed, all critical parameters and tolerance requirements from the drawing are stored in the platform database prior to quotation. This allows subsequent production and quality teams to directly access approved specifications, significantly reducing their need to interpret complex drawings and minimizing the risk of human error.

The production module of the “Huaxia Xing Intelligent Spring Design and Manufacturing Platform” schedules each order and defines the materials, equipment, personnel, processes, and inspection points required for every operation. At key stages—such as machine setup, heat treatment, shot peening, and outsourced surface treatment—quality controls including first‑article inspection, in‑process checks, and PPK/CPK monitoring are implemented based on project specifications.

The raw‑material management module of the HuaXing platform is pre‑loaded with extensive reference data, including chemical composition and tensile‑strength standards for each material grade. When new material arrives at CATALOG’s warehouse, the chemical and tensile properties from the supplier’s test report are entered into the system. The platform automatically compares the entered values against the stored standards, and alerts the warehouse manager to quarantine any material that falls outside specifications.

CATALOG implements lot‑level material tracking down to each individual wire coil. This enables full traceability from raw material to finished spring, and supports a key design feature: our spring‑design software can reference the actual tensile strength of the specific coil in inventory—rather than a generic standard value—allowing more precise stress and fatigue‑life calculations.
