After mixing, the compounding agents and raw rubber are fully integrated, giving rubber products excellent properties such as wear resistance, aging resistance, and high strength. Rubber mixing machines output rubber sheets after completing mixing. To meet the production specifications of different rubber products, cutting equipment is usually used to cut the sheets. The cutting equipment can ensure size accuracy and cutting efficiency, ensuring product quality. However, in some special scenarios, such as small-batch custom production, equipment maintenance, or handling irregular sheets, it is more flexible and convenient for workers to use cutting tools by hand.
