Customer Success Story: Customized high precision and durable mixing arms and liners for D&G Machinery

🔍 Client Background

D&G Machinery is a renowned manufacturer of high-performance asphalt mixing plants, serving clients across Europe, Asia, and the Middle East. With a strong reputation for precision engineering and reliability, D&G requires core wear parts that meet rigorous standards for strength, wear resistance, and dimensional accuracy—especially in high-load components like mixer arms and liner plates.

🧩 Project Scope & Challenges

D&G approached HT Wear Parts with two key demands:

Mixer Arm: Required high-strength, complex-shaped arms with excellent impact resistance and structural balance for long-hour operation.

Liner Plate: Required high-hardness wear-resistant liners suitable for abrasive materials and high-temperature environments.

The client emphasized rapid prototyping, dimensional accuracy, and long-term performance as critical project goals.

⚙️ Our Engineering Solution

✔ Product 1: Mixer Arm

Material: ZG310-570 high-strength cast steel

Initial Sampling: 3D printed prototype for structural and dynamic balance verification

Production Method: Lost Foam Casting (消失模工艺), enabling precise shaping of complex geometries

Post-Processing: CNC machining and heat treatment to ensure dimensional integrity and strength

✔ Product 2: Liner Plate

Material: High Chromium Cast Iron

Sample Delivery: 3D printed sample for fitment testing and visual inspection

Production Method: DISA automatic vertical molding line for consistent thickness and precision

Heat Treatment: Multi-stage hardening process to reach HRC 60+ surface hardness

🧪 Client Validation & Results

After installation and real-world operation, the results were impressive:

Mixer Arm: Maintained structural integrity after over 200 hours of continuous mixing. No deformation or balance issues were reported.

Liner Plate: Demonstrated160% longer lifespan compared to previous models, with zero early wear failures even in abrasive mix environments.

D&G approved both components for ongoing supply and officially listed HT Wear Parts as a trusted wear parts supplier for their core equipment.
