Customized Wear-Resistant Mixing Arm Assembly for Asphalt Mixing Plant

Client Profile:

The client is a professional manufacturer of concrete equipment who recently commissioned a batch of new mixing units to expand its ready-mix concrete supply chain in Southeast Asia. This model features a complex structure and high mixing frequency, imposing higher requirements on the precision, strength, and wear resistance of its components.

As the original equipment manufacturer was unable to provide compatible parts in a timely manner, the client decided to seek a third-party supplier with rapid customization capabilities for wear-resistant parts. After multiple rounds of technical evaluation, the client ultimately chose to cooperate with Ma'anshan Haitian Heavy Industry Technology Co., Ltd., commissioning a set of high-strength modular mixing arms specifically designed for the new equipment.

Challenges

At the early stage of the project, the client faced several critical challenges:

-Standard parts could not fit the new mixer structure, with interface deviations preventing proper assembly

-Desired a modular assembly design for the mixing arms to facilitate easy replacement of worn components

-Operating environment involved continuous heavy-duty, high-frequency operation, imposing very high wear resistance requirements on the product

-The client expected to complete sample design, testing, and commence mass production within 30 days

Haitian’s Response and Customization Process

🔧 Engineering Design and Structural Optimization

Upon receiving the client’s structural drawings, the Haitian engineering team promptly conducted reverse modeling and structural analysis, proposing a modular assembly design solution:

-The mixing head and connecting arm were designed as separate components, with interfaces secured by bolted connections

-Replaceable wear-resistant liners were added in high-wear areas

-Material selection focused on high manganese steel, combined with heat treatment to enhance impact resistance and fatigue strength

🏭 Rapid Prototyping and Process Assurance

-The prototype was completed within 15 days, covering mold fabrication, casting, machining, and surface treatment

-After CNC machining, full dimensional inspections and on-site trial assembly were conducted

-Client on-site testing confirmed that the mixing arm structure was stable, assembly precise, and operation smooth

Client Acceptance and Mass Production Launch

After completing a two-week operational test, the client officially approved the prototype.
The product maintained excellent condition during high-frequency mixing operations, with wear controlled within expected limits. The on-site replacement process was convenient, significantly reducing maintenance time.

Subsequently, the client placed the first mass production order. Haitian utilized its DISA vertical molding automatic production line and supporting heat treatment systems to complete large-scale deliveries on schedule, ensuring the client’s new production line was launched as planned.

Project Outcomes

🛠 High Compatibility: Product perfectly matched the client’s new equipment interfaces

⏱ Efficient Delivery: Less than 30 days from prototype design to mass production start

🔁 Extended Service Life: Wear level reduced by approximately 32.8% compared to original parts after two months of operation

🤝 Client Recognition: Haitian was listed as a long-term supplier for multiple equipment models of the client

Client Feedback

“The Haitian team demonstrated excellent responsiveness and engineering capability. The product was delivered on time, and the design is very reasonable, facilitating our future maintenance and standardized production. We look forward to expanding cooperation.”
