Q

PA66 temperature resistance selection advantages

A

The watershed between PA6 and PA66 is temperature; choose 66 for high temperature, choose 6 to save cost at normal temperature, wrong selection cannot be remedied later; after confirming effectiveness, fix the parameters and practices into the work instructions to prevent recurrence

Q

PA66 melt temperature 270-300℃

A

PA66 temperature window is only 20-30℃ above the melting point, the narrowest among the four major nylons; 300℃ is an absolute red line, measured calibration cannot be omitted; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PA66 narrow processing temperature window

A

PA66='narrow window material': temperature control precision is the threshold; a 20~30℃ window means temperature control equipment and measured calibration must be in place; crude temperature adjustment does not work on PA66.

Q

PA12 Melt Temperature Graded Setting

A

PA12 temperature is set in grades according to whether it is reinforced or not, and the temperature card must be changed when changing grades; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect arc...
