Hawen Solves 2-Hole Brick Stacking Challenge with Customized Offline Cuber System in Vietnam

In May 2026, a customized Hawen Automatic Offline Cuber System arrived at the production facility of a long-term customer in Vietnam. In early June, Hawen engineers were dispatched to the site to carry out installation, commissioning, and operational testing. Following successful integration with the existing production line, the system was officially put into operation and has been performing reliably ever since.

The customer had previously invested in a Hawen QT12-15 Automatic Block Making Machine and had achieved stable production with satisfactory output. However, as production volumes continued to increase, a bottleneck gradually emerged at the downstream handling stage.

The challenge originated from a specific type of locally produced two-hole concrete brick. Due to its geometry and production orientation, the bricks exited the block making machine in an upright position. While this configuration was suitable for molding, it created significant difficulties during the collection and stacking process. Conventional stacking systems struggled to arrange the bricks efficiently, leading to unstable stacks, frequent manual intervention, and reduced overall production efficiency.

Recognizing that standard equipment alone could not fully address the customer's operational requirements, Hawen's engineering team conducted a detailed analysis of the production process and collection line layout. Rather than applying a generic solution, the team developed a customized servo-controlled brick tilting device specifically tailored to the characteristics of the two-hole brick.

Integrated seamlessly into the collection line, the device automatically adjusts the orientation of each brick before it enters the offline cuber system. Powered by a high-precision servo control system, the mechanism ensures accurate positioning, synchronized movement, and consistent operation even under continuous production conditions. By transforming the brick orientation at a critical stage of the handling process, the system effectively eliminates the stacking instability that had previously constrained production efficiency.

Following installation and commissioning, the upgraded collection line demonstrated a remarkable improvement in automation performance. Bricks are now transferred smoothly from production to cubing without manual adjustment. The offline cuber system is capable of forming neat, stable, and uniform stacks, significantly reducing labor intensity while enhancing operational efficiency.

This project once again highlights Hawen Machinery's capability to deliver not merely equipment, but comprehensive production solutions. As a professional manufacturer of block machines, brick making machines, concrete moulds, and complete block production systems, Hawen understands that every market presents unique production challenges. Through continuous innovation and customer-oriented engineering, the company remains committed to transforming complex manufacturing obstacles into practical and efficient solutions.

The successful operation of this project in Vietnam represents far more than the commissioning of a new automation system. It demonstrates how targeted engineering expertise can unlock hidden production potential, optimize resource utilization, and elevate factory competitiveness. For modern concrete product manufacturers, sustainable growth is no longer determined solely by production capacity; it is increasingly defined by the ability to eliminate inefficiencies throughout the entire manufacturing process. By resolving a long-standing stacking challenge through intelligent automation, Hawen has once again proven that the most valuable solutions are those that convert operational constraints into opportunities for long-term advancement. This philosophy continues to drive Hawen's mission of empowering customers worldwide to build smarter, more efficient, and more competitive production facilities for the future.
