Beyond Appearance Five Key Indicators for Evaluating the Quality of a Brick Making Machine

When choosing an Exmork brick making machine, the impressive appearance and dazzling array of configurations can often be overwhelming. However, it's the inherent qualities beneath the steel and behind the data that truly determine whether a piece of equipment can create long-term, stable value. To make a wise investment, think like a professional engineer and focus on the following five key indicators that go beyond appearances.

1. Structural Strength and Manufacturing Process: The "Bone Strength" of the Equipment

A brick making machine is essentially heavy equipment that withstands immense and repeated impact. Its structural strength determines its long-term operational stability and precision retention.

Key Considerations:

Mainframe Steel Material and Welding Process: Don't just focus on steel plate thickness; pay attention to the steel material (for example, Q345B low-alloy steel is superior to standard Q235A) and the weld quality. Full welds and fish-scale welds are generally superior to spot welds, resulting in uniform, smooth welds free of pores. This ensures the equipment will not crack or deform under long-term vibration. Rib Design: Are there scientifically designed, densely packed ribs at locations where stress is concentrated (such as below the vibrating table and at the main cylinder support)? This directly reflects the designer's understanding of the force transmission path.

Why is it important? A solid "framework" ensures mold clamping accuracy, prevents problems such as uneven brick thickness and flash caused by frame deformation, and significantly extends the life of the equipment.

II. Hydraulic System Stability and Cleanliness: The Equipment's "Blood Circulation System"

The hydraulic system is the power source of the brick-making machine, and its quality directly affects molding pressure, operating stability, and failure rate.

Key Points:

Core Component Brand and Configuration: Prefer reputable brands for hydraulic pumps, reversing valves, and seals. This not only ensures durability but also ensures more stable pressure output and reduces the risk of internal leakage.

System Cleanliness: Open the hydraulic oil tank inspection port and inspect the interior for cleanliness and rust-free conditions. A system that is rigorously flushed and sealed before shipment is crucial for preventing serious problems such as oil blockage and valve core seizure. Cooling Capacity: Check whether the hydraulic station is equipped with a sufficiently large oil cooler (air or water-cooled) that matches the main machine's power. This is crucial for ensuring stable oil temperatures and preventing system overheating during continuous, high-intensity production.

Why Important: A clean, stable, and well-dissipated hydraulic system is the fundamental guarantee for continuous, efficient equipment operation and the production of high-density bricks.

III. Vibrator Performance and Mounting Method: The "Heart" of Dense Forming

The vibrator is the core that liquefies concrete, and its performance determines the initial density of the bricks.

Key Considerations:

Vibrator Brand and Type: Is it a well-known brand (such as Italy's Oli or Germany's NET) or a product from an unknown manufacturer? Is it a high-performance external vibrator or a simple shaft-mounted model?

Vibrating Force and Mounting Method: Is the exciting force sufficient and adjustable? More importantly, is the base mounting the vibrator thick and heavy, and connected with high-strength shear bolts? Fragile mounting methods are the primary cause of vibrating table cracking and bolt breakage. Why it's important: Powerful and stable vibration is crucial for ensuring uniform and dense compaction of every corner of the bricks, especially hollow blocks, and avoiding honeycombing.

IV. Intelligent and Reliable Control System: The "Brain" of the Equipment

Modern brick-making machines are no longer simple machines. Their control systems determine ease of operation, intelligent production, and efficient fault diagnosis.

Key Points:

PLC (Programmable Logic Controller) and Human-Machine Interface: Using PLCs from internationally renowned brands such as Siemens, Mitsubishi, and Schneider, or domestic first-tier brands such as Delta and Inovance, their stability and reliability far surpass those of generic or counterfeit controllers.

Program Intelligence: Does it include advanced features such as parameter memory, production statistics, and fault self-diagnosis (with the ability to indicate specific fault points, such as "2# vibrator overload")? This significantly reduces reliance on operator experience and shortens repair time.

Why it's important: A reliable "brain" ensures accurate production processes and immediately directs you to the root cause when problems arise, minimizing downtime. 5. Mold Material and Heat Treatment: The Ultimate Tool That Determines Product Quality

Molds are the components that directly shape the product, and their quality is immediately apparent.

Key Points:

Material Selection: High-quality molds are typically made of alloy steel (such as 5CrMnMo and H13) rather than standard 45# steel. Alloy steel offers superior wear resistance and toughness.

Heat Treatment: This is the "soul" of the mold. Through specialized heat treatments such as quenching and tempering, a high-hardness, wear-resistant surface layer is created within the mold, while maintaining the toughness of the core to prevent brittle cracking. You can easily test the surface hardness with a portable hardness tester.

Machining Precision: Observe the mold cavity and weld seams. A well-made mold will have a mirror-like smooth interior, with straight lines and no burrs or blemishes.

Why It's Important: High-quality molds not only last a long time and produce bricks with precise dimensions and sharp corners, but also significantly reduce the rate of defective products and downtime for cleanup caused by sticking and poor demolding. Conclusion

When evaluating an Exmork brick-making machine, it's crucial to look beyond the marketing hype and glamorous exterior to its true essence. The next time you inspect a machine, take this guide with you and personally examine its "bone strength," "blood circulation," "heart power," "brain intelligence," and "ultimate tool." A thorough assessment of these five key metrics will be your most powerful tool for making a successful investment and avoiding potential pitfalls.
