When you come across a foam-lined customer return and think you can “copy and paste” the perfect product by calling the same engraving program, the answer may surprise you – something will go wrong!

From a theoretical point of view, the CNC machine is like a rigorous executor, it only recognizes the program instructions, as if as long as the program remains unchanged, the processed product should be “twin”, exactly the same. However, the actual production scenario is far more complex than the theory, and many external factors are like lurking “troublemakers”, which may affect the quality of products at any time.

1. First of all, the discharging link, even if it is a millimeter-level position deviation, it will cause the foam to “move” during processing, and the size and shape of the final product do not match the expectations;
2. If the fixing glue is not pasted properly, the foam will shake during processing, just like the paper keeps moving when painting, and the carving accuracy is naturally difficult to guarantee;
3. In addition, the machining tool will gradually wear out after long-term use, like dull scissors, and no matter how delicate the program is, it will be difficult to exert the original effect, and the engraving edge may become rough and uneven.

It can be seen that the factors that affect the quality of foam lining products are intertwined, and it is by no means “the same process” can be fixed once and for all. In addition to the program, every detail in the processing process, from unwinding, fixing to the state of the tool, needs to be strictly controlled to ensure the stable quality of the returned products.
The above details the potential problems in machining. If you would like to add a specific scenario or highlight certain factors, please feel free to contact us.
