塑料工业制粒机的刀片是由铁基碳化钛复合材料制成。据说它的寿命比普通工具钢的刀片高出30多倍。刀片嵌入制粒模相对旋转,并把树脂挤压成大小均匀的颗粒。MMC是由非常硬的碳化钛质点弥散在合金钢的基体中构成的,具有高的韧性、良好的抗热冲击性和高的耐磨性及抗腐蚀性。当加工韧性的聚丙烯或玻璃增强塑料时, Plastic industry pelletizing blade is made of iron-based titanium carbide composite material. It is said that its life expectancy than ordinary tool steel blade 30 times higher. The inserts are inserted into the granulation die to rotate relatively and extrude the resin into uniformly sized particles. MMC is composed of very hard titanium carbide particles dispersed in the matrix of alloy steel, with high toughness, good thermal shock resistance and high wear resistance and corrosion resistance. When working with tough polypropylene or glass-reinforced plastics,
