PA6 and PA66 Selection
Sorun Belirtisi
Short shots after switching to PA66 with the same mold, or complaints about PA6 parts softening and deforming in high-temperature environments
Neden Analizi
PA66's melting point of 260°C is 40°C higher than PA6, requiring a melt temperature of 270-300°C and a higher mold temperature; directly processing PA66 with the PA6 process inevitably results in poor plasticization, and the reverse results in degradation
Çözüm
①Set process windows separately according to the melting point difference; ②select PA66 for long-term working environments above 120°C; ③select PA6 for cost-sensitive scenarios where the temperature does not exceed 80°C
Temel Çıkarım
PA6 and PA66 processes cannot be borrowed from each other; temperature rating and cost are the two dimensions of selection, and changing material must change the entire set of process parameters; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence
