In 2015, SAILI exclusively pioneered the automatic corner cutting and grooving machine, which innovatively combines the two processes of corner-cutting (die-cutting half-cut) and grooving in a single piece of equipment to complete the

process, facing the traditional pain points in the production of base and lid packaging boxes.

This invention revolutionally eliminates the die-cutting procedure before grooving, which significantly reduces the production cost for the manufacturers and greatly improves the production efficiency.

After years of technological innovation and market precipitation, we have developed a full range of automatic corner cutting and grooving machines with multiple models to meet the diversified choices of different customers, different production capacity and different process requirements. Here is the video of the simple model SLG-850S.

From 1996 to now, SAILI grooving machines have been gradually moving towards full automation and intelligence, and SLZ-928S shows its automation in the best way: servo numerical control adjustment of grooving knife , servo numerical control adjustment of edge correcting gauge, servo numerical control adjustment of large roller belt, and retention of historical data for one-button startup. It greatly shortens the preparation time and improves the responsiveness to small-lot and multi-variety orders. This grooving machine is suitable for grooving all kinds of grey boards and cardboards, the following video shows each servo CNC adjustmen t part.

SAILI automatic bi-directional slitting machine ranks first among all slitting machines in China in terms of slitting accuracy, which absolutely ensures that the four corners of the slitted grey boards are kept at a perfect 90 degrees. This is crucial for high-end boutique packaging boxes, because any small angular deviation will be magnified in the subsequent forming process, resulting in box shape incorrect, uneven seams, seriously affecting the product grade. Therefore, it is the right choice for boutique packaging box manufacturers.

The second slitting part of this slitter can also be fitted with a grooving knife, which is especially suitable for synchronous completion of the grooving operation when slitting grey boards for hardcover case making machine. The following video shows:
