It is a dovetail groove that reprocesses the surface of the extruding plate so that it forms an equal size and uniform distribution.

After the cement mortar is solidified, a large head mortise is formed in the dovetail groove, which increases the mechanical connection on the basis of the original adhesion, enhances the stability of the system, and saves construction costs.
Product Advantages:
The energy saving and environmental protection type high-speed motor is used as power source.
The combination method is freely chosen. It can be used on the construction site on a stand-alone basis, or it can be combined with the extruding line to make the product form at one time.
The use of this device for slotting can not only save a large part of labor costs, but also greatly improve the efficiency of the finished product.
has applied for a national patent for this product, and it is necessary to counterfeit it
