Product Description Product DescriptionPlastic pelletizer bladesplastic pelletizer blades are the components of a plastic pelletizer machine. They are used to cut and shred plastic material into small pieces or pellets. These blades are made of high-strength steel or tungsten carbide, and are designed to be sharp and durable for efficient processing of plastic materials. The quality of plastic pelletizer blades is an important factor affecting the performance and lifespan of the pelletizer machine. Therefore, when choosing plastic pelletizer blades, it is necessary to consider factors such as blade material, hardness, sharpness, and geometry to ensure that the blades can effectively cut and shred plastic materials and have a long service life.Click here to contact meDetailed PhotosProduct ParametersModel/SizeCustomized according to demandEach model of machine configuration tool size is differentApplicable materialPE,PP,PVC,ABS,PS,PET,etc capacity100-3000kg/hAccording to the machinematerial45# steel inlaid alloys, other tool steels, etcCan be customizedhardness55-81HRCDepending on the material, it affects the wear resistanceCertificationsPackaging & ShippingCompany ProfileFAQQ1: Beyond hardness, what steel properties are critical for long-term performance?True performance lies in the balance of hardness, toughness, and corrosion resistance. Premium steels are heat-treated to achieve an optimal microstructure that resists micro-chipping-the primary cause of edge degradation-while maintaining flexibility to withstand impact, ensuring consistent cuts and extended service life.Q2: How does a "precision-ground" profile directly impact my final product quality?A non-uniform blade profile creates friction and pressure variations, causing cell structure damage. This leads to excessive purge (moisture loss), bruising, and irregularly shaped pieces. A precision-ground edge ensures a clean, instantaneous cut that seals the product's surface, preserving integrity, weight, and appearance.Q3: Our blades wear out quickly. Is the issue sharpening frequency or the sharpening technique?Often, it's the technique. Aggressive or incorrect sharpening generates excess heat, altering the steel's temper and creating a soft, weak edge that fails rapidly. Proper sharpening removes minimal material with controlled temperatures to preserve the hardened edge, making each sharpening cycle more effective and sustainable.Q4: Why is a "balanced set" of blades more important than replacing individual knives?A balanced set guarantees uniform cutting force across the entire product stream. A single new blade in an old set creates a high point, bearing disproportionate load and causing premature failure of both the new and old blades. A matched set ensures synchronized performance, maximizing the lifespan of all components
