Bitumen cage welding

This machine automatically welds 5 horizontal and 16 vertical steel bars to form a reinforced grid structure. The precision MIG welding system creates strong, consistent welds at every intersection, producing durable cages for bitumen package transport.

 

 

 

 

Bitumen cage bending

This hydraulic bending machine forms welded steel grids into finished cage frames. It can create 90° L-shapes for corner brackets or complete rectangular frames in one operation.

 

 

 

Bitumen cage locking

After bending, the mesh frame ends feature interlocking brackets that securely snap together without welding. This creates a strong, self-locking rectangular frame for bitumen packaging.

Bitumen Cage Package Production Process

From Raw Material to Ready-to-Fill Asphalt Packaging: A Seamless 5-Step Process

Here is how our welding system transforms steel bars into secure, logistics-ready packaging for asphalt.

Step 1: Automated Mesh Welding

Our welding machine automatically positions 5 horizontal and 16 vertical steel bars.
It then performs high-strength MIG welds at every intersection, creating a single, rigid reinforced mesh panel.
Step 2: Bending & Forming

The welded mesh panel is automatically transferred to a hydraulic press brake.
In one motion, the four sides are precisely bent upwards and the ends are formed into interlocking locking brackets, creating a complete steel frame.
Step 3: Assembly with Wooden Pallet

The formed steel frame is placed onto a standard wooden pallet.
Workers use power tools to quickly fasten the frame to the pallet through pre-designed holes with high-tensile screws, ensuring a solid unit.
Step 4: Bag Insertion

A bulk bag (ton bag) is placed into the now-secured steel frame on the pallet, with its loops positioned over the frame’s edges.
Step 5: Asphalt Filling

The unit is ready for filling. Hot asphalt is poured into the bulk bag. The rigid steel frame contains and supports the bag, preventing deformation and enabling safe, stable transportation.

Application

Asphalt Production Plants: For packaging finished products like petroleum asphalt, modified asphalt, and colored asphalt.
Construction Material Logistics Centers: Provides high-volume frame production for third-party packaging services.
Major Infrastructure Projects: Supports large-scale asphalt mixing plants for highway, airport, and dam construction projects.
