Quality Control

Production Process


(1) Order Review and Technical Disclosure

1. Upon receipt of a customer order, the Sales Department, in collaboration with the Production Department, the Technical Department, and the Quality Management Department, conducts an order review to clarify key customer requirements, including product model, specifications, performance, delivery schedule, and any special requirements. The review also verifies production capacity, raw material availability, technical feasibility, and cost estimates, and results in the preparation of an “Order Review Report” to ensure that order requirements are accurately communicated to all relevant departments.
2. The Technical Department, in accordance with order requirements and industry standards, shall prepare and review technical documentation, including product design drawings, process documents, parts lists, and assembly manuals, and clearly mark critical processes, quality control points, and inspection requirements. Subsequently, the department shall organize a technical briefing session involving the Production Department, workshop teams, and inspection personnel to explain key design features, process specifications, and safety precautions, address any questions from each department, and ensure that all personnel fully understand the core production requirements.

(2) Raw Material Procurement and Incoming Inspection

1. The Procurement Department, based on the parts list and material requirements plan provided by the Engineering Department, shall select qualified suppliers (subject to supplier qualification review and inclusion in the Qualified Supplier List), enter into procurement contracts, and clearly specify the specifications, materials, quantities, delivery schedules, and quality standards for raw materials.
2. Upon arrival at the factory, the Quality Management Department shall conduct incoming inspection in accordance with the “Inspection Standards for Construction Machinery Products,” covering metallic materials, electrical components, seals, wear parts, and auxiliary materials. The department shall verify certificates of quality compliance and test reports, and perform sampling or full-inspection tests on appearance, performance, dimensions, and other relevant parameters. Only materials that pass inspection may be entered into inventory and registered; nonconforming raw materials shall be immediately labeled and segregated, and returned or exchanged in accordance with established procedures, with strict prohibition against their entry into the production process.

(3) Production Planning and Resource Allocation

1. The Production Department shall, based on order delivery lead times, technical requirements, and workshop capacity, develop a detailed production schedule that specifies the start and end dates, responsible persons, production teams, and delivery milestones for each product and each process step, and further break down the schedule into individual stages such as material preparation, machining, welding, assembly, and commissioning, thereby formulating the “Production Operation Plan.”
2. Allocate and deploy all types of resources in accordance with the production plan, including production equipment (such as cutting machines, welding machines, lathes, milling machines, etc.), measuring instruments, tooling and fixtures, human resources, and warehouse materials, to ensure that equipment is properly commissioned and calibrated, personnel are in place, and materials are issued as needed, thereby providing assurance for the smooth execution of production.
