Tips for judging the quality of shredder blades

As an integral part of the shredder, the quality of the shredder blade directly affects the processing cycle of the waste by the machine. Therefore, the shredder blade is one of the most important accessories on the shredder. So, how does the buyer judge the quality of the shredder blade?

1. Judging from the price of the shredder blade: under the same material and process conditions, the price of the shredder blade is almost the same. Customers can first understand the market price of raw materials used to produce shredder blades, and then compare the quotations of shredder blade manufacturers. If the quotation is slightly higher than the price of the material, then there is basically no problem. If the gap is large, then there is still a certain profit margin to discuss.

2. Judging from the accuracy of the shredder blade: the parallelism and thickness of the shredder blade cannot exceed the conventional size, and only a set of qualified shredder blades can be considered when such accuracy is achieved. After purchase, you can use a measuring tool, first compare the error at both ends of a single chip, and then measure whether the accuracy of the entire set of blades is consistent one by one, and then check whether there is a gap at the joint, and touch it with your hand to see if it is smooth and without tentacles.

3. Judging from the production process of the shredder blade: in addition to the material, it is the processing technology in the production process. In the production of shredder blades, every process is important, and more importantly, heat treatment. A set of qualified shredder blades must be quenched at least twice in the furnace to achieve consistent internal and external hardness, tough but not brittle edge, wear-resistant and durable.

4. Judging from the after-sales of shredder blades: under normal use, a set of qualified shredder blades can be used for less than one or two years, and more than three or five years. Therefore, when purchasing, be sure to ask for after-sales guarantee and sign an agreement. The shredder blade manufacturer promises to the user that if there is a quality problem, it can be returned and replaced unconditionally. Without such a commitment, the quality of the blade can hardly be guaranteed.

The above four points are the basic judgment methods and are for reference only.
