Kol rɔna mol dɛn simpul ɛn dɛn nid fɔ gɛt smɔl kɔmpɔnɛnt dɛn we yu kɔmpia to hot rɔna mol dɛn. Dis kin mek dɛn nɔ dia fɔ mek ɛn fɔ mek dɛn kɔntinyu fɔ de.
Kompatibiliti wit wan big rεnj כf mεtirial dεm .
Kol rana mold kin wok wit wan brayt spɛktrum fɔ matirial, inklud ɔt-sɛnsitiv polima. Dɛn nɔ de risk fɔ degrad ɔ bɔn di plastic lɛk aw hot rɔna sistɛm dɛn kin du.
I izi fɔ mek di kɔlɔ chenj .
Bikɔs di pɔsin we de rɔn kin solidify wit ɛni saykl, i izi fɔ pul di kɔlɔ we bin de bifo am kɔmplit wan we yu de mek chenj na di kɔlɔ. Dis kin mek dɛn chenj kwik kwik wan ɛn dɛn nɔ kin gɛt bɔku prɔblɛm fɔ mek di kɔlɔ kɔntamin.
Disadvantej dɛn fɔ kol rɔna mold dɛn .
Slower cycle taims kompare to hot runner molds .
Di solidification of di rana in each saikl ad to di ovala saykl taim. Dis mek kol rana mold slo pas hot runner molds.
Matirial west frɔm rɔna ɛn sprues .
Di solidified rana de eject wit ɛni pat, we de mek matirial west. Dis west fɔ risaykul ɔ trowe, ɛn ad to di kɔst fɔ prodyus.
Lɔwa pat kwaliti ɛn kɔnsistɛns we yu kɔmpia am wit hot rɔna mold dɛn .
Di difrɛns na di tɛmpracha as di plastic de flɔ tru di kol rɔna kin mek di pat dɛn we dɔn dɔn. Dis kin rilizɔt in lɔwa ɔvala pat kwaliti ɛn kɔnsistɛns kɔmpia to hot rɔna mol.
