Injection notes
The material is supplied in airtight bags, ready for use. In case that the virgin material has absorbed moisture, it must be dried with a
dehumidified air drying equipment, dew point minimum -20°C. Recommended time 2-4h.
Injection advice
For reinforced polyamides, Domo recommends the use of steel with a high content of carbon, and purified for polishing, to avoid or limit
the abrasion. For example: X38CrMoV5-1 (EN Norm) - 1.2367 /1.2343 (DIN Norm) or X160CrMoV12 (EN Norm) - 1.2601 /1.2379 (DIN Norm).
In the case of high requirements on surface quality a mould temperature of up to 120°C can be considered. The processing parameters
like processing temperatures are a recommendation and can be adjusted in function of injection machine size, part geometry / design.
