Ndeupi hukama pakati pepurasitiki jekiseni mold uye shrinkage rate?

Hukama pakati pepurasitiki jekiseni mold uye shrinkage rate yakaoma uye inopesvedzerwa nezvakati wandei zvinhu, zvinosanganisira:

1.Rudzi rwezvinhu:Mapurasitiki akasiyana ane shrinkage rates dzakasiyana, iyo inogona kubva ku0.5% kusvika 2% iyo ine mhedzisiro yakakosha pakurongeka kwedimensional uye kunaka kwezvikamu zvekupedzisira.Heino mienzaniso mishoma yemidziyo yepurasitiki ine yakajairika shrinkage rates:

2.Polyethylene (PE):PE ine yakaderera shrinkage mwero we0.5% kusvika 1%.Izvi zvinoita kuti ive yakanyatsokodzera zvikumbiro uko kugadzikana kwedimensional kwakakosha, sekurongedza uye zvinhu zvevatengi.

Polypropylene (PP):PP ine mwero wepakati wekuderera we 0.8% kusvika 1.5%.Ichi chinyorwa chinoshandiswa zvakanyanya kune akasiyana maapplication, zvinosanganisira zvinhu zvemumba, kurongedza, uye zvikamu zvemotokari.

Acrylonitrile-Butadiene-Styrene (ABS):ABS ine mwero wepakati shrinkage we1% kusvika 1.5%.Ichi chinyorwa chinowanzo shandiswa mumashandisirwo uko kunofanirwa kuramba, kuoma, uye kugadzikana kwedimensional, senge matoyi, zvemagetsi, uye zvikamu zvemotokari.

Nylon (PA):Nylon ine mwero wakanyanya kuderera we 1.5% kusvika 2%.Ichi chinyorwa chinowanzo shandiswa mukunyanya-kushushikana kunyorera, senge magiya nemabhengi, uye mumashandisirwo uko kugadzikana kwedimensional hakusi chinhu chakakosha.

2, Ukobvu hwemadziro:
Wall ukobvu ndechimwe chezvinhu zvakakosha zvinogona kukanganisa shrinkage mupurasitiki jekiseni kuumba.Heino maitiro:

Madziro akakora anowanzo kuve neakakwira shrinkage rates,sezvo zvimwe zvinhu zvinodiwa kuzadza mold, zvichiita kuti pave nehupamhi hwepamusoro.Iyo yakakora chikamu chemadziro, iyo nguva yakawanda inotora kuti kupisa kuparare, izvo zvinogona kuguma neinononoka kutonhora mwero uye yakakwirira shrinkage.

Ukobvu hwemadziro husina kuenzana hunogona kuguma nekuderera kwekusaenzana, sezvo zvikamu zvakasiyana-siyana zvechikamu zvichatonhora uye kusimba pamitengo yakasiyana.Izvi zvinogona kukonzera kurwisana, kukanganisa, uye zvimwe zvisizvo zvisina kunaka muchikamu chekupedzisira.

Kuti uderedze shrinkage uye uwane zvinowirirana, zvemhando yepamusoro zvikamu, zvinowanzodikanwa kukwidziridza kugova kwemadziro uye kushandisa maitiro ekudzora maitiro senge tembiricha yekudzora, inononoka jekiseni kumhanya, uye kuzadza kwakaringana kwemagodhi.Pamusoro pezvo, maturusi ekuenzanisa, senge finite element analysis (FEA), anogona kushandiswa kufanotaura shrinkage uye kukwenenzvera dhizaini yekudzikisira kukanganisa kwayo pachikamu chemhando.

3, Chikamu geometry:
Iyo geometry yechikamu chepurasitiki inogona kuve nemhedzisiro yakakosha pakuderera nekuti inokanganisa nzira iyo ipurasitiki inoyerera, inotonhora, uye inoomesa mukati memukuvhute.

Complex geometries: Zvikamu zvine ma geometries akaoma, senge undercuts, homwe dzakadzika, uye macurves, zvinogona kuguma munzvimbo idzo purasitiki yakavharirwa uye haigone kuderera zvakaenzana.Izvi zvinogona kukonzera kuderera kwemazinga munzvimbo idzi uye zvinogona kukonzera kurwisana, kukanganisa, uye zvimwe zvisizvo zvisina kunaka muchikamu chekupedzisira.

Kuyerera kwezvinhu: Nzira iyo purasitiki inoyerera ichipinda uye inozadza mold inogona zvakare kukanganiswa nechikamu geometry.Kana iyo plastiki isingayerere zvakaenzana munzvimbo dzese dze mold, inogona kukonzera yakakwirira shrinkage mazinga mune dzimwe nzvimbo.
Chiyero chekutonhora: Mwero wekutonhora wepurasitiki unokanganiswawo nechikamu chejometri.Munzvimbo dzine ma geometries akaoma, mapurasitiki anogona kutora nguva yakareba kuti atonhodze uye agadzikane, izvo zvinogona kuguma nepamusoro shrinkage rates.

4, Mold tembiricha:

Kupisa kwechiumbwa kunokanganisa chiyero icho plastiki inotonhora uye inoomesa.Kupisa kwepamusoro kwe mold kunogona kukonzera kunonoka kutonhora, izvo zvinogona kuwedzera shrinkage.Sezvineiwo, tembiricha yakaderera mold inogona kukonzera kukurumidza kutonhora mitengo, iyo inogona kuderedza shrinkage asi inogona kuguma nekuwedzera warping uye kumwe kusarongeka kwedimensional muchikamu chekupedzisira.

Xiamen Ruicheng ane akapfuma ane ruzivo mainjiniya timu pane jekiseni mold matekinikiizvo zvinosanganisira kushandisa maitiro ekudzora maitiro, senge tembiricha yekudzora masisitimu uye mold tembiricha sensors, pamwe nekugadzirisa mold dhizaini uye kugadzirisa mamiriro kuti ive nechokwadi chekutonhodza yunifomu uye inowirirana chikamu chemhando.

Xiamen Ruicheng chiziviso: kungwarira prototyping uye kuyedzwa kunogona kubatsira kuona zvingangoitika uye kukwenenzvera dhizaini ye mold yezvikamu zvinowirirana, zvemhando yepamusoro.
