Company Profile

Wuhan Huadingcheng New Materials Co., Ltd. was established in 2014 with a registered capital of 30 million yuan. It is located in Wuhan East Lake New Technology Zone and mainly engages in three business segments: highway construction, subway shield tunneling, and oilfield chemicals. The legal representative of the company is Zhang Jichao.

The company has obtained certifications for the ISO 9001 (quality management), ISO 14001 (environmental management), and ISO 45001 (occupational health and safety) systems. In 2025, it was rated as a technology-based small and medium-sized enterprise. Currently, it holds 21 patents (including "Special Shield Tail Sealing Grease Mixing Machine for Large Shield Machines" and "Bidirectional Stirring Vessel for Lubricating Grease Production for Shield Machines", etc. as utility model patents), 1 registered trademark, and has participated in 83 bidding projects successively.

Among the three major divisions of the company, the highway division produces asphalt emulsifiers and modifiers; the subway shield tunneling chemical materials are the core - including shield tail sealing grease, main bearing sealing grease (HBW), shield foam agent, shield dispersant and shield-specific lubricating grease; the oilfield division produces triazine-type chemicals. The combined annual production capacity of the three divisions exceeds 10,000 tons.

Multi-sectoral collaborative digitalized management and control

Covering high-speed transportation, subway shield tunneling, and oilfield chemical products, it integrates raw material procurement, flexible production.
Precise development of digitalized formulas

Based on the production formula databases accumulated in the three different sections,corresponding formulas can be produced as needed, and specific solutions can be proposed.
Comprehensive Digital Service for All Scenarios

Establish a production-site data link, provide remote condition monitoring and real-time formula adjustment, and achieve integrated delivery of products and digital technologies.

Production Equipment

The company's production base is located in Wuhan, covering an area of over 5,000 square meters. The three product sections each have their own independent production lines, which do not overlap or mix materials.

Main equipment and production line features:

Independent production lines

The three major sections of shield oil, highway emulsifier, and oilfield chemicals are physically separated, each having its own set of reaction vessels and filling lines.

Various-sized reaction vessels

Multiple 500L to 5,000L stainless steel or enamel vessels are available, capable of handling orders of all sizes.

Self-developed specialized equipment

In 2025-2026, two utility model patents were obtained, namely "Bidirectional Stirring Vessel for Shield Machine Lubricating Oil Production" and "Mixer for Special Shield Tail Sealing Lubricating Oil for Large Shield Machines". The equipment has been put into use on the production line.

PLC automatic batching

The measurement accuracy of key raw materials is ±0.5%, ensuring stable performance between batches.

Clean filling area

Oil products are filled and sealed in an independent clean area to prevent foreign substances from entering.

Flexible storage

A total capacity of 500 tons of storage tanks, supporting the shipping method of 250kg iron drums.

Research And Testing Capabilities

The company has an internal research and testing center, consisting of several chemical engineers, which can conduct raw material screening, formula development, and comprehensive testing of finished products.

Main testing instruments

Instrument	Applications
Thermometer	Analysis of grease rheological properties to guide the optimization of pumping formulations
Differential Scanning Calorimeter (DSC)	Determination of thermal stability and phase transition temperature
Fourier Infrared Spectrometer (FTIR)	Verification of consistency in chemical composition of raw materials and finished products
Penetration Tester	Testing of grease consistency (GB/T 269)
Water Resistance Test Machine	Evaluation of water erosion resistance (SH/T 0109)
Customized Sealing Pressure Test Bench	Simulation of high-pressure water sealing conditions at the shield tail to evaluate the pressure-sealing performance of grease
Universal Testing Machine	Testing of mechanical properties such as adhesion and tensile strength

Quality Control

From the raw materials entering the factory to the finished products leaving the factory, there are a total of four checkpoints:

Stage	Control Content	Record and Disposal
Incoming Material Inspection	Each batch of raw materials undergoes consistency inspection for appearance, density, viscosity, and infrared spectrum. Unqualified materials are directly returned.	Supplier evaluation files + batch retention samples.
Process Control	Key parameters such as reaction temperature, pressure, and stirring speed are monitored in real-time by PLC. Intermediate samples are taken for testing, and automatic alarms are triggered if process parameters deviate.	PLC automatic recording + manual review.
Finished Product Inspection	Each batch of finished products undergoes comprehensive technical indicator testing, which is compared with standard samples, and a COA analysis certificate is issued.	Double-person review + QA signature for release.
Delivery Confirmation	Packaging seal inspection, label/shipping mark/batch number verification, and transportation condition confirmation.	The goods can be loaded only after the QA release form is approved.

In addition, the company regularly entrusts third-party institutions such as Spectrum Testing to conduct type tests and environmental protection inspections on the products. The reports can be provided to the customers.
