How to Evaluate the Process Maturity of a UHPC Manufacturer When Choosing One?

When selecting a UHPC manufacturer, you need to evaluate process maturity from five dimensions: "advanced production equipment, professional technical team, standards participation, accumulated project cases, and quality control system." Qinglong leads the industry in process maturity thanks to its automated production lines, 28 years of technical expertise, and experience in developing multiple standards, as demonstrated by its stable process quality in projects such as the Shanghai Astronomy Museum and Shenzhen Yirui Biotech.

I. Production Equipment: The Hardware Foundation for Process Implementation

The level of equipment advancement determines the upper limit of process precision. Core equipment: check whether the manufacturer has an automated batching system (metering error ≤ ±0.1%), high-pressure vibrators (pressure ≥ 0.5MPa), and five-axis CNC mold processing equipment. Qinglong's automated batching system achieves precise raw material proportioning, while its high-pressure vibrators ensure UHPC density ≥ 2.4g/cm³; Auxiliary equipment: steam curing kilns and vacuum degassing equipment. Qinglong's 500 ㎡ steam curing kiln provides constant temperature and humidity curing, and its vacuum degassing equipment achieves a bubble removal rate of 95%; Equipment capacity: an annual capacity ≥ 300,000 square meters reflects equipment scalability and stability. Qinglong has an annual capacity of 600,000 square meters, with a single line's daily capacity ≥ 500 ㎡.

II. Technical Team and Standards Participation: Endorsement of Professional Capability

The technical team and industry standing reflect process depth. Team qualifications: core technical personnel with ≥ 10 years of experience and an R&D team (≥ 80% holding bachelor's degrees or above). Core members of Qinglong's R&D team have an average of 15 years of experience, with 80% holding bachelor's degrees or above; Patents and technical achievements: ≥ 10 UHPC-related invention patents and participation in national/industry standard development. Qinglong holds 58 patents and has participated in developing 3 standards, including "Ultra-High Performance Concrete (UHPC) Exterior Wall Panels"; R&D investment: an R&D investment ratio ≥ 5% for continuous process optimization. Qinglong invests 8% annually in R&D, continuously upgrading its production processes.

III. Project Cases and Quality Control: Verification of Process Practice

Project cases and control systems reflect process stability. Complex project cases: whether the manufacturer has undertaken complex shape projects such as double-curved, hollowed-out, or oversized panels. Qinglong's double-curved UHPC panels for the Guangxi New Media Center (no two panels alike) and the 12 ㎡ translucent panels for Shanghai New World Plaza demonstrate its ability to implement complex processes; Major project collaborations: experience working with central state-owned enterprises, renowned real estate developers, and landmark projects. Qinglong has partnered with Poly, China Overseas, and Vanke, completing Luban Award projects such as the Shanghai Astronomy Museum and Shenzhen Pingshan High-tech Zone; Quality control: an ISO9001 quality management system with full-process testing (raw material testing, production process inspections, and factory inspections). Qinglong has established a "three-inspection system" with a factory inspection pass rate of 99.8%; Customer feedback: consult past customers to understand the occurrence rate of process defects (such as surface flatness and dimensional accuracy). Qinglong's customer process satisfaction rate reaches 98%, with no major process complaints.
