Stainless steel is hard and does not rust easily. Martensitic stainless steel is best for wet or rough places. Ferritic stainless steel is good for food or medical shredders.

Initial Inspection

You must check the steel before shaping it. Look for cracks or bad spots. Make sure the surface is even. Only the best steel goes to the next step. Skipping this check can make weak blades. Weak blades do not last long.

Preparation Steps

You must get the steel ready before making blades. The table below shows steps that help blades last longer:

Follow these steps to help your blades:

• Rough grinding helps the blade have the right size. This step makes the blade work better and last longer.
• You must control heating and cooling during annealing. This stops uneven hardness and stress inside the blade. It also makes the blade stronger.

Note: Picking the right material and preparing it well helps make strong shredder blades.

Shredder Blade Processing

Blanking and Forging

Process Overview

First, workers shape raw steel into blade blanks. They use blanking to cut steel sheets into rough shapes. Heavy presses push down on the steel. This forms the basic outline of each blade. Workers watch the temperature closely. High heat makes the steel soft. Soft steel is easier to shape. They must check pressure and heat to stop cracks or weak spots. The goal is to make a blank that fits the design and size needed.

Nanjing Metal’s Advanced Forging Techniques

Nanjing Metal uses special forging machines. Sensors watch temperature and pressure all the time. This keeps each blade blank strong and the same. Custom dies let you pick different blade shapes. You can choose single-shaft, double-shaft, four-shaft, or claw designs. Each die matches the blade type you want. This way, blades are strong and last long. You get blades that work well for shredding.

Cắt Laser

Process Overview

After forging, laser cutting shapes the blade blanks. Powerful lasers cut steel with great accuracy. Computers control the cutting path. This step saves material and reduces waste. Blade blanks have exact sizes. The process is quick and clean. No chemicals or extra cleaning are needed. You save time and keep the area safe.

Here is a table showing how laser cutting helps:

Nanjing Metal uses modern laser machines. You can ask for special blade shapes and tight sizes. The automated process keeps blade blanks the same every time. Blades fit your shredder just right. This technology lets you pick custom designs for different jobs.

Stamping Techniques

Process Overview

Stamping adds features to blade blanks. Machines punch holes and notches in the steel. You set the machines to repeat the same action. This step gives blades the right holes and edges. Results are always the same. Stamping is fast and uses steel well.

The table below shows the main advantages of stamping:

Nanjing Metal’s Stamping Innovations

Nanjing Metal uses very accurate stamping dies. Automated checks find mistakes early. You get blades with the same features and fewer errors. This helps you get blades that work well in shredders. You can pick different blade types and sizes for your needs.

Forming Blade Blanks

Process Overview

You reach a key step when you form blade blanks. This step shapes the steel into the basic form of a shredder blade. Workers use machines to trim the edges and smooth the surfaces. They check the size and thickness to match the design. You see the blade start to look like its final shape. Edge profiling gives the blade its cutting angle. Surface smoothing removes rough spots. These steps help the blade fit well in the shredder and work with less friction. You get a blank that is ready for more finishing.

Tip: Careful shaping and smoothing at this stage help your shredder blade last longer and cut better.

• You decide on the number of teeth or claws.
• You can request special holes or notches.

This process gives you more control over your shredding results.

Differences in Processing for Various Blade Types

Not all shredder blades are the same. Each type needs a different process. You see this in the way single-shaft, double-shaft, and claw-type blades are made. The table below shows some main differences:

You notice that single-shaft shredders use square blades. These blades need strong steel and careful shaping for soft materials. Double-shaft shredders use claw knives. These need a different forging die and special edge work. Claw-type blades handle bulky waste. They need extra shaping and sometimes more teeth. Each type of blade blank goes through a unique process to match its job. This ensures your shredder works well for your material.

Xử lý nhiệt

Heat treatment is very important for shredder blades. It makes blades strong and tough. This process changes steel so it can handle hard jobs. There are three main steps: hardening, tempering, and stress relief. Each step helps the blade last longer and work better.

Làm cứng

Purpose and Process

Hardening is the first step. Workers heat the blade to very high temperatures. The steel changes inside and forms austenite. Then, they cool the blade quickly. This makes martensite, which is very hard.

Temperature Control and Quenching Methods

Workers must watch the temperature and cooling speed. The table below shows how different cooling methods change the blade:

Workers pick the best cooling method for each blade. Oil quenching gives a good mix of hard and tough. This helps blades last longer.

Impact on Blade Strength and Wear Resistance

Heat treatment makes blades harder and stronger. Blades keep their sharp edges longer. You do not need to sharpen them often. They can cut tough things like metal scraps and stones.

Nanjing Metal’s Advanced Hardening Techniques

Nanjing Metal uses special heat treatment steps. You get blades with high hardness (HRC 58-62). Workers control the temperature carefully. They use the right cooling method for each job. These steps help blades work well in tough places.

ủ

Purpose and Process

Tempering comes after hardening. Workers heat the blade again at a lower temperature. This step makes the blade less brittle and more bendable.

Temperature and Duration Optimization

Workers must choose the right temperature and time. If they temper too long, the blade gets soft. If they temper too short, the blade stays brittle. They use careful controls to get the best result.

Balancing Hardness and Toughness

Tempering helps blades be hard but not easy to break. This balance is needed for shredding many materials.

Nanjing Metal’s Tempering Innovations

Nanjing Metal uses modern ovens for tempering. You get blades with the right mix of hard and tough. Workers check each blade to make sure it is just right.

Stress Relief

Purpose and Process

Stress relief removes hidden stress inside the blade. This step stops the blade from bending or warping when used.

Methods for Reducing Internal Stresses

Workers use two main ways:

• Indirect aging: They machine the blade, then let it rest.
• Direct aging: They use heat or other methods to relax stress.

These ways help the blade keep its shape.

Enhancing Blade Stability and Longevity

Stress relief makes blades stable and long-lasting. Blades keep their size and work well in shredders.

Nanjing Metal’s Stress Relief Procedures

Nanjing Metal uses advanced stress relief steps. You get blades that meet design standards and work reliably.

Tip: Heat treatment is the secret to strong shredder blades. You get blades that last longer and work better for every shredding job.

Precision Machining

Precision machining shapes each shredder blade into its final form. The blade must have the right size and be very sharp. If there is a small mistake, shredding can go wrong. Nanjing Metal uses advanced machines to keep sizes almost the same. This makes sure every blade fits well and cuts quickly.

mài

Grinding is the first step in precision machining. Grinding makes the blade smooth and flat. It removes rough spots from earlier steps.

Surface Grinding

Surface grinding makes the blade flat and even. You put the blade blank on a magnetic table. The grinding wheel moves over the blade and takes off thin steel layers. This makes the blade the right thickness and smooth. A flat blade fits tightly in the shredder.

Edge Sharpening

Edge sharpening works on the blade’s cutting edge. Special grinding wheels make the edge sharp and exact. A sharp edge helps the blade cut tough things easily. It also lowers the chance of jams or bad cuts. Workers look at the edge with magnifiers to check if it is good.

Milling

Milling shapes the blade more. Computer machines cut grooves, slots, or special parts in the blade. Milling also makes the right angle for the cutting edge. This step is important for custom blade shapes. You can ask for special shapes or features for your job.

Note: Grinding and milling keep the blade size very close to the plan. This means every blade works the same way each time.

Here is a table showing typical tolerances for shredder blades in different industries:

Small tolerances help the blade fit and work better. High precision means less shaking and smoother shredding.

hoàn thiện

Finishing is the last step in precision machining. You polish the blade to remove tiny burrs or sharp edges. This step also makes the blade look better and stops rust. Workers check each blade for size, shape, and sharpness. Only good blades go to the next stage.

• You get blades with almost no size mistakes.
• You receive blades that are sharp and ready for hard jobs.

Tip: Precision machining helps your shredder blades last longer and work better.

Shredder Blade Manufacturing Process Quality Control

Quality control is very important when making shredder blades. It helps make sure every blade is safe and lasts long. Nanjing Metal checks each blade many times. These checks help stop problems before they start. They also keep your shredder working well.

First, workers look at each blade closely. They search for cracks or rough spots. They use calipers and gauges to measure size. Workers check if the blade is sharp and straight. If a blade is not right, it does not move on. This step finds mistakes early and saves time later.

• Looking at the blade finds surface problems.
• Measuring tools check the blade’s size and shape.
• Checking the edge makes sure it can cut well.

Tip: Checking early helps you save money and keeps your shredder safe.

Kiểm tra hiệu suất

You need to know if a blade works well before using it. Workers test how strong and sharp the blade is. They use the blade to cut different things. They see how long the blade stays sharp. They also check how much force is needed to cut.

Testing follows rules from around the world. These rules help keep people and the environment safe. You see rules from ISO, CE, and REACH in Europe. North America and Asia have their own safety rules. Following these rules takes more time and money. But it helps stop fires or injuries.

• Safety and environmental rules are important.
• Tests use plastics, metals, and rubber.
• Results show if the blade meets world standards.

Note: Following these rules keeps you and your team safe from blade problems.

Defect Checks

After testing, workers check for defects again. They use machines and their eyes to find hidden cracks. They look for problems like warping or uneven hardness. If they find a problem, they take out the blade.

You want blades that pass all the checks. This helps you get blades you can trust for your shredder.

Tip: Careful checks help you avoid stopping work and keep your shredder running well.

Final Assembly

Blade Assembly

You reach the final stage when you assemble the shredder blade. Workers fit each blade into its mounting position. They use special tools to make sure the blade sits tight and straight.
