Questa è una email di un cliente di MP3 Srl, che descrive un problema:

Dear Paolo, and all, 
 
 I want to hereby provide preliminary information about quality defect on the foil 1009618 PP HOMO REP BLACK 20% TALC 435x0,6 MM # our PO 4500050915. 
 Please see the scan of your label attached. 
 
 We noticed on finished parts after the forming that there are strips on them. Please see the pictures attached. 
 We checked also the foil itself, visually by naked eye no defect is visible. 
 
 Nevertheless , as we did a very detailed control of tools as well as all the stations on the machine and didn´t find any problem we presume the defect is on the foil. 
 Moreover, it is appearing on the 2 types of the machines after the forming, on a different product (because it is also on the code 1007790 PP HOMO REP BLACK 20% TALC 610x0.6 MM). 
 
 To speed up the process of investigation, we kindly ask you for support and quick action, I want to ask for following and inform you about further steps we intend to do: 
 
 - Please see the picture attached # try to assess from them what can be the route cause 
 - We will send you samples of the foil as well as finished parts with defect (foil 1009618 # please see the copy of your label attached), 
 - The sample of the foil # despite of the fact defect is not visible on foil, please investigate (by maybe spectrometry or other method) the structure and composition of the foil if any potential cause can be revealed 
 - The sample of the finished part # please check the defect, and asses the cause of the problem based on your expertise and experience, it is true we haven´t encountered such before 
 - Please investigate with your specialists or with external laboratory and come with proposal what method can be used to detect to cause of the problem 
 
 
 I want to emphasise it is not and imprint from our tools, or something from the machine. During the forming there are parts which are perfectly ok, and parts which are affected by the problem (not very deep imprints # these parts are released for further production and finialising) and parts affected very strongly, these parts are stopped and thrown away like reject. 
 
 We are now monitoring the % of such scrap. 
 
 We are concerned on the phenomenon, we keep investigating with the material of more recent batches and we will see the evolution. 
 
 It is true that this phenomenon is appearing also on the foil code 1007790 (our highrunner). 
 
 
 My colleague from Quality department Simona Turianova will provide more details on the problem tomorrow, please communicate (Quality MP3) with her further. 
 
 
 I want to ask you , like a person responsible for Purchase and materials, to pay attention to this phenomenon, because we have quite significant problem and my concern is to have too much material affected and thus not usable. 
 We need to keep producing and not stopping the lines on our customer´s side. They do not accept parts with these strips. Please pay attention to this and start to work on this asap, as soon there will be a holiday period, you will be closed and we need to find the cause of the problem. 
 
 
 I hope this will not be that "large" problem and it will stop soon, but are noticing that this phenomenon has been appearing for the period of month +/- already. 
 
 
 Simona, 
 
 Please proceed with needed inputs and reports as well as samples to be sent asap. 
 
 
 Thank you all in advance.
