Case Erector Machine: Something You Need To Know About

01 Apr 2024

In the world of manufacturing and packaging, efficiency is paramount. One essential piece of equipment that contributes to streamlined packaging processes is the case erector machine. A case erector machine is sometimes ignored but vital in the packing sector since it automates the process of building cardboard boxes, saving time and labor expenses. In this article, we delve into more about case erector machines.

What Is The Case Erector Machine?

A case erector machine, also known as a box erector or carton erector, is a mechanical device designed to erect corrugated cardboard boxes or cases automatically. These machines are frequently employed in industries that require high packing efficiency, including food and beverage, pharmaceuticals, cosmetics, e-commerce, and logistics.

Functions Of A Case Erector Machine

The primary function of a case erector machine is to streamline the process of erecting cardboard boxes. Here are the main processes of a case erector machine:
Pick and Feed: The initial function of a case erector machine is to pick up flat cardboard blanks from a magazine or stack and feed them into the erecting mechanism. This procedure is often automated, with sensors ensuring that each blank is precisely positioned for maximum efficiency.

Forming and Folding: Once the cardboard blanks are fed into the machine, the erecting mechanism engages to form the boxes. To make the base of the box, fold the bottom flaps of the cardboard blank following pre-scored lines. The machine employs mechanical arms, suction cups, or other gripping mechanisms to manipulate the cardboard and ensure accurate folding precisely. Box Sizing and Adjustment: Case erector machines are designed to accommodate a wide range of box sizes and styles. Advanced variants include automatic size modification capabilities, which allow the machine to adapt to various box dimensions without the need for manual reconfiguration. This versatility allows manufacturers to switch between product lines with ease and minimize downtime.

Sealing: Once the box is formed, the case erector machine seals the bottom flaps to secure the contents inside. Depending on the machine type, sealing can be done with pressure-sensitive adhesive tape or hot melt glue.  Tape case erectors apply adhesive tape along the bottom seam of the box, while glue case erectors use heated glue to bond the flaps together. Both methods ensure a strong and tamper-evident seal. Output Conveyor: After sealing, the built boxes are transferred from the machine to an output belt, where they continue to the next stage of the packaging process. The conveyor system can be integrated with other packaging machinery, such as case packers or labeling machines, to create a seamless production line.

Maintenance and Troubleshooting: Regular maintenance is essential to keep case erector machines operating at peak efficiency. Maintenance tasks may include lubrication, cleaning, and inspection of mechanical components to prevent breakdowns and extend machine lifespan. In the event of a malfunction or downtime, troubleshooting procedures are available to quickly diagnose and rectify issues, reducing production disruptions.


In conclusion, a case erector machine is an important part of modern packing operations since it automates and streamlines the process of assembling cardboard boxes.  If you are looking for a trusted food packing machine supplier, Soontrue is ideal for you.
