Compression Molding
Kumangirira ndi njira yopangira momwe polima yotenthetsera imayikidwa pamalo otseguka, otentha. Chikombolecho chimatsekedwa ndi pulagi yapamwamba ndi kukakamizidwa kuti zinthuzo zigwirizane ndi madera onse a nkhungu.
Njira imeneyi imatha kupanga zigawo zautali, makulidwe, ndi zovuta zambiri. Zinthu zomwe zimapanga zimakhalanso zamphamvu kwambiri, zomwe zimapangitsa kuti zikhale zokopa m'mafakitale osiyanasiyana.
Ma composites a Thermoset ndiye mtundu wodziwika bwino wazinthu zomwe zimagwiritsidwa ntchito pomanga.
Njira Zinayi Zazikulu
Pali njira zinayi zazikuluzikulu zopangira ma thermoset composite compression process:
- A mkulu mphamvu, awiri mbali zitsulo chida analengedwa kuti ndendende zikugwirizana miyeso zofunika kutulutsa ankafuna gawo. Chidacho chimayikidwa mu makina osindikizira ndikutenthedwa.
- Chophatikizika chomwe chimafunidwa chimapangidwa kale mu mawonekedwe a chida. Pre-forming ndi gawo lofunikira lomwe limathandizira kukonza magwiridwe antchito a gawo lomaliza.
- Gawo lopangidwa kale limalowetsedwa mu nkhungu yotentha. Chidacho chimakanikizidwa pansi kwambiri, nthawi zambiri kuyambira 800psi mpaka 2000psi (malingana ndi makulidwe a gawolo ndi mtundu wa zinthu zomwe zimagwiritsidwa ntchito).
- Gawolo limachotsedwa ku chida pambuyo pa kukakamizidwa kumasulidwa. Kuwala kulikonse kwa utomoni kuzungulira m'mphepete kumachotsedwanso panthawiyi.
Ubwino wa Compression Molding
Kupaka compress ndi njira yotchuka pazifukwa zingapo. Chimodzi mwa kutchuka kwake kumachokera ku kugwiritsa ntchito zida zapamwamba. Zidazi zimakhala zamphamvu, zolimba, zopepuka, komanso zosagwirizana ndi dzimbiri kuposa zitsulo, zomwe zimapangitsa kuti zikhale zapamwamba kwambiri. Opanga omwe amazolowera kugwira ntchito ndi zitsulo amapeza kuti ndizosavuta kutembenuza chinthu chopangidwa ndichitsulo kukhala gawo lopangira psinjika. Chifukwa ndizotheka kufananiza gawo lachitsulo la geometry ndi njira iyi, nthawi zambiri munthu amatha kungotsitsa ndikulowetsa gawo lachitsulo palimodzi.
