PA612 also polyamide (PA) 612 or nylon 6 12, formed separation is poly 十二烷二酰 hexamethylenediamine. PA612 remove tool has generally PA features outer, also tool has versus for wide degree small, more low water absorption and density, dimensional stability good advantages, has relatively high tensile strength and impact strong/high degree, transparent degree.
applications:
PA612 main/primary used for: made high grade and its it industrial use filament, can used for made as precision machine parts and electrical cable by coating, tube/pipe, oil resistant 绳索, belt/tape, bearings, and other, military industry upper can used for made 枪托, and use cable and other.
injection molding process:
drying 处理:
if processing front material is 密封, that 么就没 has necessary drying. however, if container by 打开, that 么建议 in 85℃ hot gas in drying 处理. if wet degree large 于0.2%, also need need 进行105℃,12 small true drying.
mold wet degree:
建议80℃. mold temperature degree will effect/influence crystallization degree,而 crystallization degree will effect/influence product material features. for/regarding thin parts, if use low 于40℃ mold temperature degree,则塑 parts crystallization degree will time 而变化, is maintain parts stability property, need 进行退火处理.
injection pressure:
usually in 750~1250bar,取决于材 material and new product design.
injection molding speed degree:
high speed (for/regarding reinforcement type material low 一). runner and gate: due to PA612r凝 solid time very short, therefore gate non important. gate 孔径不 need small 于0.5*t (this 里t is parts thick degree). if use hot runner, gate dimensions ratio use runner small 一,因 is hot runner can 够帮助 retardant material solid. if 潜入式 gate, gate most small 直径应当 is 0.75mm.
