Aerated Block Strapping Line – Gansu Project

Minxian County, Gansu, sits at the junction of the Longnan mountain area and the Loess Plateau. Building materials produced here often have to travel over winding mountain roads to reach surrounding towns and villages. For aerated block manufacturers, whether the strapping is secure before shipment directly affects transport safety and customer satisfaction.

Recently, a Aerated Block Strapping Line supplied by Qingzhou Shuangfengda Mechanical Engineering Co., Ltd. completed installation and commissioning at an aerated block production facility in Minxian County and officially entered operation. The equipment uses a strap-through method to fully automatically strap stacked aerated blocks. The entire process requires no manual assistance and eliminates the use of wooden pallets.

Why choose pallet-free strapping?

Traditional aerated block packaging relies heavily on wooden pallets. This not only requires continuous pallet purchases and takes up storage space, but pallets themselves are prone to damage, leading to considerable long-term expenses. Shuangfengda‘s pallet-free solution uses high-strength PET strapping to directly secure the block stacks. The stack itself becomes a stable unit without needing pallet support. After strapping, the stacks can be moved by forklift, stacked for storage, and conveniently loaded onto vehicles.

For this customer in Minxian County, local road conditions are less than ideal. Aerated blocks must be delivered to construction sites in multiple directions. Whether the stack is tightly strapped directly affects whether the blocks arrive intact. The strap-through method passes the strap through the interior of the stack, and after tensioning, the strap fits snugly against the block surfaces, providing even force distribution and significantly reducing the risk of loosening.

Stable operation and positive customer feedback

After the equipment went into operation, the customer reported that the strapping pace keeps up with the production line speed, the block stacks are neat and uniform, and forklift operators find them easier to handle during loading. The worker responsible for strapping noted that they used to have to bend down many times each day, but now they simply press a few buttons on the control panel to get the job done.

During commissioning, Shuangfengda‘s technicians adjusted the strap travel distance and tension settings to match the production specifications of aerated blocks in the Minxian area. They also provided simple operational training for the customer’s personnel, covering routine inspections and handling common machine prompts.

Securing the final checkpoint for Minxian‘s aerated blocks

This pallet-free strapping line is not large and accounts for only a small section of the entire production process. But for this company in Minxian County, the final checkpoint before its products leave the factory is now firmly in place. The customer noted that with this equipment, they feel more confident when shipping goods, and customer complaints have noticeably decreased.

Shuangfengda will continue to provide reliable strapping equipment and technical support for the building materials industry, helping more companies improve quality and efficiency in their packaging operations.
