⚠️ Injection Advice

The material is supplied in airtight bags, ready for use. If the virgin material has absorbed moisture, it must be dried with dehumidified air drying equipment (dew point minimum -20°C). Recommended drying time: 2-4 hours.

For unfilled polyamides, DOMO recommends the use of high alloy steel with a low chromium content. For example: X38CrMoV5-1 (EN Norm) – 1.2367/1.2343 (DIN Norm).
