Hot Cut Knife Blades

Carolina Knife & Manufacturing, Inc., manufactures and distributes several different hot cut knife assemblies that have many uses in industry and textile manufacture. While these blades are extremely useful, if they are used by untrained, careless hands, serious injury could occur. We’d like to take this opportunity to give our customers some helpful tips for using our hot cut knife products safely, ensuring that you and those you work with continue to go home at the end of the day with all of their extremities intact. 

How Hot Cut Knives Work

For those unfamiliar with hot cut knives, or need to use one and have had no experience with them, here is a brief overview of how they function and are operated. Hot cut knifes use electricity to heat a blade to a hot enough temperature to cut, shape, and seal different synthetic materials. These materials include textiles like acrylic fabrics, polyester, and nylon, as well as foam, styrofoam, webbing, sailcloth, and rope. Natural materials are typically not cut using a hot knife, since they have a tendency to react poorly to high temperatures. The same is true for the synthetic material called vinyl, which melts easily due to its plastic content. 

Hot knives can cut through most synthetic materials to create a seamless edge. Its uses are not limited to industrial work, either. Hot cut knives have practical applications in laboratories, kitchens, and hobby and craft stores. The main advantage of using a hot knife foam cutter is that it seals while it cuts, creating an edge that is much less likely to fray or unravel over time. The same cannot be said for other cutting tools, like razors or scissors. The heat from the hot knife cutter melts and binds filaments together, making the edge more or less permanent. Check out one of our most popular hot cut knife assemblies, the Zetz-24 Hot Knife Thermocutter for a great example of this type of tool.

Safely Operating a Hot Cut Blade

The size and primary function of hot cut blades can vary depending on the application, but the same general rules apply for safe operation. Once there is power going to the heating element, the blade will become very hot in a matter of seconds. The utmost care should be taken to not let any part of your body come into contact with the hot blade. Heat-resistant gloves are recommended in the event that your hand slips and contacts the blade. You should have a firm, secure grip on the handle of the hot blade handle. Always be aware of your surroundings and any other person that may be working near you. 

As you prepare to cut, take note of the surface that you’re cutting on. You should strive to cut on a flat surface that will not be damaged by exposure to high heat. Most manufacturers use a workspace covered by a sheet of glass. Any material that you are cutting is much less likely to accidentally stick to glass while it is heated. 

You should always use a hot cut blade in a ventilated area. While not all materials are harmful, it is always better to protect yourself from potentially toxic fumes. Inhaling fumes from heated materials may not poison you, but they certainly could nauseate you. Save yourself the trouble and work with proper ventilation. 

Once the hot cut blade is suitably heated, you will be surprised at how easily it cuts through most synthetic materials. While your blade glides along, avoid pausing. Doing so could cause the material to melt too much and build up, resulting in an uneven cut. When you are finished cutting, make sure that the blade is placed in a proper safety holder, the power is turned off, and that the blade has enough time to cool before being stored or touched for sharpening.

Industrial blades are much different from the knives you would find in your kitchen drawer. Industrial blades are generally used to cut or shred an incredible variety of materials. From food and plastics to the toughest steels and non-ferrous materials, industrial knives and cutting edges are used to reduce the size and process of all kinds of materials.  However, one thing that industrial knives have in common with the knives you typically would find in the kitchen is that they will last longer if they are properly cared for.

Quick and Easy Care Tips For Industrial Blades

If you are like most people, you may not know where to start when it comes to proper care for industrial blades, let alone regular blades in general. Luckily, in this blog, we are going to share three quick tips to provide your industrial knives with better care.

1. Properly Store the Industrial Knife

When you are not using your knives, it is important to keep them packed in a box or package that allows the industrial knife blade or the cutting edge to remain protected. Falling, bumping, or hitting the blade can damage it. It is best to keep the blade in a container that will keep the knife from moving around. You’ll also want to ensure that the container will not nick the cutting edge in anyway.

2. Cover the Cutting Edge

It is important that an industrial knife’s cutting edge is protected at all times. There are some easy ways to ensure the cutting edge of your industrial knife remains protected: some people choose to dip the edge in melted plastic. Others prefer to put a wooden or rubber scabbard around the outside of the edge. Covering the cutting edge with protective material will ensure that nothing can nick the blade of your industrial knife when it isn’t being used.

3. Prevent Rusting

Most industrial knives are made of steel, making them susceptible to rusting. To avoid this, it is wise to put a rust preventative on the knife. Rust preventative typically needs to be applied once, and most industrial knife manufacturers will apply it to their products before sending them out. If the knives are stored in a moist or damp area, it may be best to apply an additional coat of rust preventive down the road.

By following these quick and simple tips, you can better care for your industrial knives. Keep an eye out for future posts, as we will be sure to cover more helpful care and maintenance tips. Remember, if your knives are taken care of they will generally last longer.

Despite innovation of automation, tire production still requires a lot of demanding work. And, due to the unique physical characteristics of rubber, cutting processes require a blade that is specially designed for seamless and consistent cutting of this tough material. Those in the tire and rubber industry look to the industrial blades and knives from Carolina Knife & Manufacturing, Inc. As one of the leading industrial knife manufacturers in the U.S., we manufacture a full line of tire manufacturing and rubber converting blades.

Tire Cutters and Rubber Cutting Blades

Whether your manufacturing processes involve the slitting and rewinding rubber, sheeting rubber, or any tire cutting processes involved in manufacturing tires, you can find the right blades and accessories from Carolina Knife & Manufacturing, Inc. We only use the highest quality grades of carbon steel and tungsten carbide in our tire cutting knives and rubber conversion cutters for the best results. Plus, with custom knife manufacturing available, we are able to meet the needs of your manufacturing processes. Some of the industrial blades and knives for the tire and rubber industry that  we manufacture include:

Score Slitter Blades

Carolina Knife & Manufacturing, Inc., manufactures blades and a wide range of accessories for machines utilizing the score or crush cutting process in the tire and rubber industry. Score slitting parts the rubber material through a crushing action, therefore, the cutting edges of these blades cannot be sharpened. They typically have a radius along the cutting edge. No manufacturer can compete to the attention to detail of the cutting edge on our blades.

Rotary Slitter Blades

Rotary shear slitting is the tire and rubber industry equivalent to the cutting process used by a pair of scissors. In rotary shear slitting there are two cutting surfaces, the top and bottom blades. These rotary slitter knives spin in opposite directions allowing the tough rubber material to pass smoothly through the blades. Carolina Knife supplies a wide range of rotary cutting blade designs in all popular materials.

Burst Slitting Razors

You can find a wide range of thin, extra-sharp razor slitter blades to meet the needs of the tire and rubber converting industry. Industrial razor slitting, also called burst slitting, is a single knife cutting process in which an ultra-thin, extremely sharp blade, either circular or straight, is held in position while a sheet of material is drawn over the blade. The sharp blade passes smoothly through the rubber material to cut it into two pieces and enable faster cutting speeds.

Mill Knives

Mill knives are most commonly used in the manufacturing of rubber sheets, which are used in the final assembly of products such as rubber tires and hoses. Typically, mill knife blades are very sharp and made of higher grade tool steel which enables a long run life.We make sure that the mill knives we manufacture have cutting edges that are very sharp and have long cutting life in the converting of these rubber materials.

Sheeter Knives

Sheeter knives are used in a rotary motion to affect the cutting of sheets of material to certain desired lengths. The wide range of materials that we use to manufacture sheeter knives means that we have the right blade and the right material for tire and rubber converting applications.

Straight Shear Blades

Straight shear knives have evolved into many uses in the tire and rubber industry. The process of shearing is a proven technique effective at cutting the rigorous material in this industry. At Carolina Knife Co., we can manufacture any shear from various high quality materials to improve the performance of your cutting processes.

Hot Cut Knives

Carolina Knife & Manufacturing, Inc. manufactures hot cut knives, pneumatic hot cut knives, and hot cut assemblies for tire and rubber converting. The hot cut knife consists of a holder and an element or blade that operates at up to 1500 degrees Fahrenheit. This enables industry materials to be cut and sealed in one operation. Hot cut knife converting can be more cost effective than Ultrasonic slitting when edge fraying or unraveling is a primary concern.

When it comes to the plastics processing industry, granulator blades endure some of the most grueling materials and conditions. Granulating hard plastics can cause the blades to dull, leading to frequent blade replacements. To get the blade functionality and cut quality back to an optimal condition, professional and precise sharpening is required. This will significantly help increase the life of the blade and will improve the output of the granulator. Sharp blades will allow machines to operate more efficiently, which will help increase the overall output of the machine will creating more consistency with output at the same time.

The Best Way to Sharpen Industrial Knife Sharpening Equipment

Professional industrial knife sharpeners utilize state-of-the-art sharpening equipment and methods specifically developed for the care and maintenance of granulator blades. After sending your dull and worn granulator blades for sharpening, they will be returned in a like-new condition. This better ensures that the gap between each granulator rotary blade and bed knife is maintained through more hours of operation.

Selecting an Industrial Knife Sharpening Service

Before sending your granulator blade to be sharpened, it is important to choose a sharpening service that will have an understanding of the blades’ tolerance requirements. Every granulator machine that has a set of blade tolerances that must be implemented when sharpening. These tolerances state the allocated measurements for the width of both new and sharpened blades and knives.

For instance, knives with holes that are typically found in fixed blade granulators cannot be adjusted. That said, these knives must meet the straightness and width requirements established by the industrial knife manufacturer.

How Exactly Are Industrial Blades Sharpened?

Proper blade sharpening is a process that involves various steps. Precise blade sharpening typically begins with cleaning the blade to remove any residue and facilitate a high-quality sharpening. Then, the blades are carefully measured and sorted to make sure that the least amount of blade material is removed while ensuring the tightest tolerances throughout the set of blades.

To properly sharpen granulator blades, the knife is held in place and precisely rotated to match the exact angle requirements needed to meet the tolerances of the granulator machine. Most granulator blades can be sharpened at least 10 times before reaching the end of its life. Proper and professional sharpening will dramatically reduce the overall costs of maintaining your granulator.

What to Do Before Sending Your Blades for Sharpening

When granulator blades are due for sharpening, they should be sent as a complete set. This helps ensure that the blade tolerances required by the granulator manufacturer are maintained. It is also important that the sharpener understand what type of material will be granulated with the blades, as thinner materials often require tight blade tolerances and should only be sharpened by knife sharpening services that can maintain the specified tolerance throughout the blade set.

Lastly, to measure the effectiveness of your current sharpener, maintain a log of sharpening and blade conditions. Before shipping the blades out, make note of the condition and width of each blade and do the same when the blade is returned. If the sharpener is removing too much material, the life expectancy of the blade is unnecessarily reduced.

Maintaining the quality and sharpness of granulator blades will help ensure the optimal performance of granulator machines, resulting in more effective throughput and higher-quality output. While maintaining the condition of industrial knives may seem like a burden, teaming up with an experienced industrial knife sharpener who understands and complies with the strict tolerances set by your granulator equipment manufacturer can help reduce the overall costs.
