⚠️ 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.
Due to the abrasiveness of carbon fiber, DOMO recommends using steel with high carbon content, purified for polishing, to avoid or limit abrasion. For example: X38CrMoV5-1 (EN Norm) – 1.2367/1.2343 (DIN Norm) or X160CrMoV12 – 1.2601/1.2379 (DIN Norm). For high surface quality requirements, mold temperature up to 120°C can be considered.
