Slitting machine quality appraisal

slitting machine is mainly composed of a blanking part, a transmission system, a cutter part and a rewinding part. When working, the control transmission system drives the unloading part to send the large-format material to the cutter. The cutter cuts it into the required size and then sends it to the rewinding part for coiling.

slitting machine is widely used in paper products, tapes, electronic materials, plastic products, medical equipment and other fields. It can greatly improve the efficiency and accuracy of material slitting and is widely used in digital printing, label manufacturing, advertising packaging and other fields.
In the case of slitting machine quality appraisal, Zhongke Testing can provide slitting machine quality appraisal services.

Among buyers and sellers, there are cases of disputes caused by slitting machine failures. Zhongke Testing compiled slitting machine quality appraisal cases and summarized common slitting machine failures.
1. The slitting machine cannot rotate normally, mainly because the equipment is overloaded and the frequency converter will cause an overcurrent alarm.
2. The unwinding head of the slitting machine cannot open or contract, which is often related to the equipment's hydraulic tension solenoid valve output line roadblock, causing the solenoid to not operate normally.

Party A and Party B signed a "Product Purchase and Sales Contract" to purchase two slitting machines of a certain model. During use, Party A found quality problems with the slitting machine and sent a letter to Party B to negotiate. Party B also arranged for engineers to go to Party A for debugging but failed. Because the two parties could not reach an agreement through negotiation, Party A filed a lawsuit in court.
was entrusted by the court to conduct an appraisal and analysis on "whether there are quality problems" with the slitting machine involved in the case.
identification and analysis results: The
identification and analysis expert group discussed the relevant information and on-site investigation of the slitting machine involved in the case and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions: HTMLTAGTOKEN The 7.8um capacitive film roll sample extracted from the 7.8um capacitive film sample cut by the slitting machine involved in the case on site had a basin-shaped end face of one batch of film rolls and a film layer displacement of one batch of film rolls, which did not meet the requirements of the "Technical Specification of a Certain Model of High-Precision Metalized Film Slitting Machine" stipulated in the contract.
