Corrugated Knife Basics
What Is a Corrugated Knife
A corrugated knife is a special tool for cutting cardboard. It has a special edge that helps it cut through thick paper and cardboard. Factories use this blade to make neat lines and shapes in packaging. The blade needs to stay sharp to cut tough cardboard fibers. Workers in factories use the corrugated knife to keep things running well. The right blade helps cut faster and makes better cuts.
Role in Packaging
Packaging companies use the corrugated knife for many jobs. Workers cut, score, and shape cardboard sheets with this blade. The blade must cut thin and thick cardboard. Good blades help save material and keep boxes strong. Clean cuts mean smooth edges on the cardboard. This keeps items inside safe. The corrugated knife also makes folding lines for easy box assembly. Every cut is important in making packaging. A sharp blade helps each piece fit just right.
Tip: Picking the right blade for each kind of cardboard and paper can make packaging better and help machines work longer.
Slotter Blades Overview
Slotter blades are important in making corrugated packaging. These blades, also called slotting knives, cut slots and lines in cardboard. Slotter blades must be fast and accurate for quick machines.
Fitur Desain

The way a corrugated knife is made is very important for factories. Every part, like the blade’s material, shape, and how it is heated, changes how well it cuts and how long it lasts. These things also affect how good the cardboard packaging looks in the end.
Bahan Pisau
Picking the best blade material helps the knife cut better and last longer. Each material has its own good points for cutting cardboard and paper.
Bahan Pisau | Keuntungan | Kekurangan |
---|---|---|
Baja Kecepatan Tinggi (HSS) | Durable, excellent edge retention | More expensive |
Baja Karbon | Excellent edge retention, sharp edge achievable | Prone to rust, requires regular maintenance |
Besi tahan karat | Good corrosion resistance | May not hold edge as well as carbon steel |
Keramik | Excellent sharpness and edge retention | Fragile, prone to chipping and breaking |
Titanium-Coated | Enhanced durability and corrosion resistance | Coating can wear off over time |
Karbida Wolfram | Very durable, maintains sharpness for long time | Expensive, prone to chipping |
Perkakas Baja
Tool steel is a common choice for cutting blades in packaging. It is hard and tough, so it works well for fast cutting. Tool steel blades do not wear out quickly and keep their sharp edge. This helps factories make neat cuts and stop machines less often.
Baja Berkecepatan Tinggi
High-speed steel blades are even stronger and stay sharp longer. These blades are good for busy factories that cut a lot of cardboard. They do not need to be changed as often, so workers save time and money.
Geometri Bilah
The shape of a corrugated knife changes how it cuts cardboard and paper. The right shape makes smooth, clean cuts and keeps the packaging strong.
Corrugated Edge
A corrugated edge has a wavy line that matches the shape of corrugated cardboard. This shape stops the blade from shaking and makes the edges cleaner. It also keeps the cardboard from getting crushed. Corrugated edge blades are best for new and high-quality packaging. They help keep the edges smooth and the boxes looking nice. Factories use these blades to make boxes that pass tough tests.
Corrugated edge blades are best for making neat, strong boxes that need perfect cuts and strong sides.
Serration Patterns
Serration patterns have small teeth close together to help the blade cut better. These teeth move bits of cardboard away and stop the blade from getting stuck. Serrated blades are great for cutting recycled or thick cardboard. They work well when the cardboard has different layers or dirt inside. These blades also cut thick materials where it is hard to keep the blade clean.
- Serrated blades cut recycled and thick cardboard easily.
- The special teeth make cutting easier and protect the blade.
- Factories use these blades to cut tough materials quickly and neatly.
Perawatan panas
Heating the blade the right way is very important. It makes the blade hard, tough, and last longer. Nanjing Metal uses special heating steps to make sure every blade is strong and works well.
Perawatan panas Teknologi | Key Features & Benefits | Impact on Blade Performance & Industry Standards |

Special heat treatment helps blades last longer, need less fixing, and is better for the planet.
Cutting of Corrugated Cardboard

Pemotongan Presisi
It is very important to cut corrugated cardboard accurately. Many things affect this, like the type and thickness of the cardboard. The cutting machine must be steady. The person using the machine needs skill. Good corrugated knives and slotter blades help make cuts that are exact. These blades stay sharp and do not wear out fast.
Some cutting machines use special motion control systems. Oscillating knife CNC cutters are one example. These machines pick the best tools and settings by themselves. Keeping machines clean and oiled helps them work well. This also keeps the cuts the same every time.
The blade material also matters for making good cuts. The table below shows how each material works when cutting corrugated cardboard:
Bahan Pisau | Properti Utama | Application in Corrugated Cardboard Cutting |
---|---|---|
Baja Karbon Tinggi | Hardness 58-60 HRC; cost-effective but corrodes | Pemotongan serbaguna |
Besi tahan karat | High corrosion resistance (90% under saline) | Food and medical packaging requiring rust resistance |
Baja Perkakas D2 | High wear resistance (600-650 MPa under load) | Pemotongan volume tinggi di lingkungan abrasif |
Baja Kecepatan Tinggi M2 | Retains sharpness up to 600°C | Pemotongan kecepatan tinggi untuk pembungkus industri |
Karbida Wolfram | Very high hardness (up to 90 HRC), excellent wear resistance | Abrasive materials, extends blade life significantly |
Keramik | Chemically inert, lightweight, brittle under impact | Precision cutting in delicate applications |

Tungsten carbide blades last much longer than high-carbon steel blades. They can last three times longer in tough cutting tests. This means better cuts and less time fixing machines.
Clean Cuts and Scoring
Good packaging needs clean cuts and straight scoring lines. Corrugated knives and slotter blades do this with sharp edges and special blade shapes. Some blades have coatings like Teflon. Teflon can make cutting easier by up to 80%. Zr-based coatings can lower friction by 51%. These coatings help blades stay sharp and make smoother cuts.
The table below shows what makes a blade cut well:
Fitur | Pisau Berkualitas Tinggi | Pisau Standar |
---|---|---|
Kualitas Bahan | Engineered for sharpness and durability | Lower durability |
Pemotongan Presisi | ±0.01 mm, minimal waste | ±0.03 to ±0.05 mm, less precise |
Daya tahan | Up to 300,000 cuts | 150,000 to 200,000 cuts |
The tip of the blade is important too. A lamella edge is thin and makes very clean cuts. A bevel edge is strong and good for tough jobs. Rounded and straight edges are not as exact but work for simple cuts. Changing how the blade is set and moved can make cuts better and safer.
- Lamella edge: Makes clean, even cuts.
- Bevel edge: Cuts tough stuff and stops mistakes.
- Rounded edge: Good for easy scoring jobs.
Slotter blades from Nanjing Metal use these designs. Their blades help factories waste less and make boxes look better.
Preserving Material Strength
It is important to keep corrugated cardboard strong when cutting. The right way to cut stops the board from getting crushed. Oscillating knife-cutting machines help keep the cardboard’s shape and strength. These machines also help make better box designs and stop damage.
Different perforation patterns help balance easy tearing and strength. Some examples are:
- Speedi Tear: Keeps boxes strong but easy to open.
- Cascade: Easy to tear but may change how the box looks.
- Zipper: Lets people open boxes fast, used in online shopping.
Special knives, like the 5/5 standard knife, are made for these patterns. The way the holes are made and the cutting method should not make the box weak. Crush cutting with a circular knife helps keep the board strong and makes neat cuts.
Packaging Applications

Corrugated Box Production
Making corrugated boxes needs careful cutting of cardboard and paper. Pisau slotter putar are very important for this job. These blades cut, slot, score, crease, and punch holes in cardboard sheets. This lets factories make boxes in the right shapes and sizes. Each blade shape, like straight, curved, or wavy, does a special job. Some make straight cuts, while others make round slots. High-speed rotary slotter machines move cardboard sheets through spinning shafts. This helps factories make lots of boxes that all look the same. The sharp blades make neat crease lines and slots. These lines help fold and put boxes together. Factories waste less material and make stronger boxes. Custom rotary slotter blades fit certain machines and packaging styles. They help factories work faster and stop less often. Keeping machines clean and changing blades on time keeps everything working well. This makes sure every box is good quality.
Specialty Packaging
Specialty packaging needs special shapes and features. Cutting cardboard for displays or fancy packaging must be very exact. Slotter blades with special angles and teeth stop damage to the cardboard’s flute. This keeps the box strong and looking nice. Factories use these blades to make packaging that looks good in stores and keeps products safe. Custom blades can cut different thicknesses and flute types. This means they work for many packaging styles. Nanjing Metal makes sure each blade is high quality and fits what the customer needs. Their blades help with easy folding, putting together, and even opening, like tear lines or holes.
Note: Custom slotter blades help specialty packaging by matching each project’s needs.
Internal Partitions and Inserts
Cardboard partitions and inserts protect things inside boxes. Factories use die-cut machines with many blades to make these parts. They cut out shapes, slots, and holes to fit each product. These inserts keep items away from the box walls and give them a cushion. This stops things from moving and getting broken. Using strong cardboard, like Kraft or white finishes, makes the inserts last longer and look better. Custom inserts are easy to put together without tools. This helps factories pack things quickly. Customers like how these cutting methods make packing fast and neat.

Speed and Output
Corrugated knife design helps factories cut faster and work better. The wavy edge lets the blade move through cardboard with less push. This makes cutting and creasing easier and quicker. When factories use new cutting methods, they make more boxes in less time. For example, one box plant changed from regular slitter knives to custom micro-tooth blades. After the change, their downtime each month dropped from 14 hours to less than 5 hours. They also did not have to change blades as often. This gave them more time to cut boxes and less time fixing things.
Jenis Pisau | Penggantian Bulanan | Waktu henti (jam) | Total Biaya Bulanan |
---|---|---|---|
Standard Slitter | 12 | 14 | Tinggi |
Custom Micro-Tooth | 3 | 4 | Rendah |
The table shows how better cutting can help factories do more work. Good cutting methods let workers finish big jobs faster and with less effort.
Mengurangi Sampah
Cutting and creasing well does more than make things faster. It also helps factories waste less material. Clean cuts mean less cardboard gets ruined or thrown away. Factories using special slotter blades from Nanjing Metal see smoother edges and fewer mistakes. This means less scrap and better use of materials. Good cutting also keeps the cardboard strong, so boxes meet quality rules. Workers can trust these cutting ways to keep waste low and make more boxes.
Tip: Using the right cutting ways and sharp blades helps factories save money and care for the planet.
Lower Downtime
Less downtime is a big plus of new die-cutting systems. Custom blades made from tough materials like tungsten carbide or hardened steel last up to 50% longer than regular blades. This means workers do not have to change blades as much. Less time is spent fixing and cleaning. Cleaning, storing, and sharpening blades the right way makes them last even longer. Factories that check blades often can find problems early and stop sudden breakdowns.

Better corrugated knife design helps factories make more boxes. It also helps make boxes stronger and faster. Sharp, tough blades cut neatly and waste less material.
