PROCESS FOR PREPARING INJECTION MOLDED PARTS WITH DECREASED GLASS FIBER READ OUT AND INJECTION MOLDED PART |
摘要 |
The present invention relates to a process for preparing an injection molded part, comprising the following steps: a preparing a glass fiber reinforced polyamide-6 composition with a relative viscosity of less than 2.4; b heating a such composition to obtain a viscous liquid; c filling a mold cavity with the viscous liquid with a filling time of at least 0.8 s; d leaving the viscous liquid in the mold under pressure until it cools to form a part; e opening the mold; f ejecting the part; wherein the polyamide-6 composition has a crystallization temperature under hyper DSC conditions of less than 168° C. The invention also relates to an injection molded part a having a maximum wall thickness of at least 2.5 mm; and/or b a part weight of at least 100 g per injection point; wherein the part consists of a glass fiber reinforced semi-crystalline polyamide-6 composition having a relative solution viscosity of less than 2.4, wherein the polyamide-6 composition has a crystallization temperature under hyper DSC conditions of less than 168° C. |
