The plaintiff *** Machinery Co., Ltd. and the defendant *** Co., Ltd. brought a case to a people's court due to a sales contract dispute. The applicant and defendant disputed the following issues: whether the
plate rolling machine complies with the contract requirements; whether the products produced meet the requirements; whether the required dimensions and positioning accuracy of the products rolled by the plate rolling machine meet the requirements; whether the rolling shapes are the same based on the same parameter settings;
was entrusted by the court, and our company accepted the appraisal and analysis of "whether there are quality problems" of the plate rolling machine involved in the case.
appraisal analysis results: The
appraisal analysis expert group discussed the relevant information and on-site investigation of the plate bending machine involved and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions: The
plate bending machine does not meet the requirements of the standard GB/T 30463-2013 CNC plate bending machine. The plates rolled by
plate rolling machine do not meet the quality requirements of the attachment of the "Industrial Products Sales Contract", that is:
(1) The shape of the rolled plate is different from the drawing;
(2) The positioning accuracy tolerance of the plate rolling machine, that is, the tolerance of the starting and tail spacing of the rolled plate is not within ±5mm;
(3) The tolerance of the curling degree of the rolled plate is not within 3 degrees.
