What Types Of Materials Can The Automatic Grooving Machine Process?

Sep 28, 2026 Leave a message

Automatic slotting machine is mainly used in the production and processing of rigid packaging such as paper boxes, gift box, shoebox and electronic products. When choosing an automatic slot machine, suppliers check the material, board thickness and product structure of the device, not just the speed or price of the machine.

Different packaging materials are different in hardness, thickness, fiber structure, etc., which affects the final molding effect after slotting. Choosing a device that matches the material ensures consistent groove sizes and smooth folding, while also improving the efficiency of subsequent processes such as paper laminating and box assembly.

1. Industrial Paperboard

Industrial paperboard is a commonly used material made by automatic slotting machine. It is widely used in cardboard boxes and high grade packaging products.

This kind of cardboard has special hardness and hardness, requires the V-shaped grooving to form the wrinkle line, enables the cardboard to bend and form according to the design specification.

When configuring equipment, suppliers usually select appropriate cutting tools and slotting parameters based on the thickness, size of the cardboard and structure of the product.

Common applications include:

Gift boxes

Premium packaging boxes

Product display boxes

High-end paper packaging

Commercial packaging boxes

For mass production enterprises, automatic feed, positioning, feed and other functions help to reduce labor and improve overall production efficiency.

 

2. Greyboard

Grey board is another commonly used material in rigid box production. Because of its excellent rigidity and structural support, it is often used in packaging products that require a stable, three-dimensional shape.

Automatic slotting machines can cut continuous or intermittent V-shaped grooves in the surface of the grey board, laying the necessary foundation for subsequent folding, assembly and lamination.

In actual production, the thickness of the grey board directly affects the slotting effect. If the groove is too shallow, it is difficult to bend the plate; if the groove is too deep, it can affect the structural integrity of the box.

Therefore, when selecting equipment for customers, the supplier must adjust parameters according to the actual board thickness and product structure, rather than simply selecting the machine according to the product name.

 

3. MDF and High-Density Fiberboard

Some products with rigid packaging and special structures use MDF or high-density fiberboard as a base material. Compared with standard paperboard, these materials differ in density, hardness and processing characteristics.

When machining MDF with automatic slotting machine, key factors to be considered include board thickness, slotting depth, slotting angle and tool configuration.

For buyers dealing with multiple material types, it is advisable to provide the supplier with an actual sample to verify that the machine meets specific processing requirements before purchasing the equipment.

This allows for advance validation of groove profiles, edge quality and folding performance, thus minimizing compatibility risks when the device is acquired.

 

4. Other Rigid Boxes Composite Panels

In addition to industrial paperboard, gray cardboard and MDF, some cardboard packaging manufacturers utilize other cardboard that provides specific hardness and thickness.

These materials can be used in a variety of box structures, such as irregularly shaped boxes, folding boxes and premium packaging with multiple folding lines.

When dealing with this material, suppliers typically need to understand the following details:

Specific Material Type

Sheet thickness

Maximum and minimum processing dimensions

Number of grooves required

Spaces between grooves

Required groove angle

Subsequent folding and lamination processes

The more accurate the material information, the easier it is to select the right equipment and fine-tune the processing parameters.

 

 

5. Selection an Automatic Grooving Machine Based on Board Thickness

The thickness of plate is the key factor which influences the effect of automatic grooving. For rigid box grooving equipment, specific models are usually designed to handle specified material thickness ranges.

Take Koten Machinery's SW-A series automatic slotting machines, which support sheets about 0.6-4mm thick and are suitable for industrial cardboard, ash boards, MDF and more.

In the purchasing process, attention must not solely be paid to the machine's maximum processing thickness of the machine, but also to the specifications of materials used mainly for routine operations.

If over 80% of customer orders involve 1-2 mm of ash, the machine's ability to continuously process this particular range is far more important than simply pursuing larger theoretical processing power.

 

6. Material Dimensions and Groove Structure Must Also Be Considered When Selecting Equipment

Just because a material can be processed does not mean that the device is suitable for all of a company's products. In addition to the material itself, it is necessary to verify that the length, width and number of grooves of the plate are within the scope of the equipment.

For example, some rigid box products require multiple parallel slots, while complex box designs may involve different slot spacing and unique structural features.

When assisting with equipment selection, suppliers typically request product drawings, board dimensions, and actual samples to verify:

Compatibility with maximum processing dimensions

Compliance with minimum processing requirements

Sufficient number of grooves;

Applicability of tool configuration

groove angles aligned with product specifications

subsequent flatness of folding and shaping.

This approach is much more reliable than simply choosing a device based on the name of the product.

 

7. How do different materials affect the slotting process?

Different materials lead to different edge mass, bending properties and structural integrity behind the groove.

For paperboard materials, accurate control of the location and depth of the groove, to prevent the paper crackings, grooves uneven, poor folding performance and other issues.

For high density plates, emphasis is placed on tool performance and processing stability.

As suppliers, we generally advise our customers to test material before making a final purchase. Actual sample testing allows for a clearer assessment of the suitability of the equipment for the target material and helps to determine the best processing parameters.

 

8. What are the main products used in the production of automatic slotting machines?

Automatic slotting machine is mainly used in rigid packaging and premium box industry. The finished material is eventually used in various packaging products.

Common products include:

Packaging of mobile phones and electronic products

Shoe boxes

Clothing packaging

Jewellery boxes

Cosmetic packaging

Chocolate and food packaging

Gift boxes

High-end packaging

Automatic slotting machines are often considered preliminary processing equipment for packaging manufacturers. After slotting, the plate goes through further steps such as paper lamination, folding, bonding, and box assembly, which means the machine's processing precision directly affects downstream production.

 

9. Supplier Advice: confirm Verify Material Compatibility prior to purchase

From a supplier's perspective of view, the most important factor when buying an automatic slot machine is not merely comparing prices, but also verifying that the device matches your specific material and product.

The following information is recommended to be prepared before purchasing:

Samples of actual plates used

Plate thickness range

Maximum product dimensions

Minimum product dimensions

Number of slots per product

Slotted angle requirements

Monthly or daily production

If the company plans to introduce new packaging products in the future, it should notify suppliers in advance to select equipment with sufficient processing capacity and flexibility.

Only when the material, product structure and equipment parameters match can the automatic slotting machine truly realize the value of automatic production.
