Spr\u00f8jtest\u00f8bning af plast<\/h2>\n<\/div>\n<\/div>\n

Vi er meget professionelle\u00a0plastspr\u00f8jtest\u00f8bningsvirksomhed i Kina<\/a>S\u00e5 jeg vil meget gerne introducere dig til processen med plastspr\u00f8jtest\u00f8bning.<\/p>\n

Alt dette harpiksmateriale startede generelt som plastpiller. Pillerne f\u00f8res ind i en af de store spr\u00f8jtest\u00f8bemaskiner, som ofte vejer omkring 25 tons. Maskinen opvarmer plasten, indtil den er flydende. Denne v\u00e6ske presses derefter gennem injektorer ind i spr\u00f8jtest\u00f8beforme.<\/p>\n

Disse spr\u00f8jtest\u00f8beforme kan laves i n\u00e6sten enhver form eller st\u00f8rrelse. For at sige det enkelt er spr\u00f8jtest\u00f8bning en proces, hvor smeltet plast presses ind i et formhulrum. N\u00e5r plasten er afk\u00f8let, kan emnet spr\u00f8jtes ud. Det er nyttigt, n\u00e5r delene er for komplekse eller for dyre at bearbejde. Med denne proces kan der laves mange dele p\u00e5 samme tid ud af den samme plastspr\u00f8jtest\u00f8bning.<\/p>\n

Processen best\u00e5r normalt af seks trin:<\/p>\n

1. Fastsp\u00e6nding: Indspr\u00f8jtningsmaskinen har tre dele. Indspr\u00f8jtningsformen, klemmen og indspr\u00f8jtningsenheden. Fastsp\u00e6ndingsenheden holder formen ved et bestemt tryk, hvilket sikrer ensartethed i de enheder, der udsendes.<\/p>\n

St\u00f8beforme best\u00e5r normalt af to dele.<\/p>\n

2. Indspr\u00f8jtningsenhed: Det er her, plastpillerne fyldes i en tragt i toppen af indspr\u00f8jtningsenheden. Pillerne f\u00f8res ind i hovedcylinderen, hvor de opvarmes, indtil de er blevet flydende. Inde i indspr\u00f8jtningsenheden er der en skrue, som drejer og blander plasten. N\u00e5r den flydende plast har n\u00e5et det optimale niveau for dette produkt, starter indspr\u00f8jtningsprocessen. Plasten presses gennem en gran, og trykket og hastigheden styres af skruen eller nogle gange af en stempel, afh\u00e6ngigt af maskintypen.<\/p>\n

3. Dwelling: Dette er en pause i processen, mens der l\u00e6gges et vist pres for at sikre, at alle formhulrummene er fyldt helt ud. Dette er meget vigtigt i processen, da det vil resultere i skrotning af enheder, hvis formen ikke er fyldt korrekt.<\/p>\n

4. Afk\u00f8ling: Denne del af processen lader formen k\u00f8le af i den n\u00f8dvendige periode. Hvis det sker for hurtigt, kan enhederne kl\u00e6be eller blive deforme, n\u00e5r de er ude af maskinen.<\/p>\n

5. Formen \u00e5bnes: Sp\u00e6ndeenheden \u00e5bnes for at adskille formen. St\u00f8beforme bruges igen og igen; de er ofte den vigtigste enkeltdel i hele processen. V\u00e6rkt\u00f8jet til formen kan v\u00e6re meget dyrt.<\/p>\n

6. Udst\u00f8dning: Det f\u00e6rdige produkt skubbes ud af spr\u00f8jtest\u00f8bemaskinen. Ofte vil det f\u00e6rdige produkt forts\u00e6tte p\u00e5 en produktionslinje eller blive stablet for at g\u00e5 til en produktionslinje som dele til st\u00f8rre produkter, f.eks. et bilrat.<\/p>\n

De produkter, der bruger spr\u00f8jtest\u00f8bning, bruges hver dag af os alle sammen. Mange biler ville ikke v\u00e6re s\u00e5 billige, hvis det ikke var for spr\u00f8jtest\u00f8bning, men der er nogle ulemper ved processen. Maskinerne er meget dyre og indeb\u00e6rer en stor kapitalinvestering, designet af delene skal tage h\u00f8jde for produktionsprocessen, og processen er ikke \u00f8konomisk for sm\u00e5 serier af produkter.<\/p>\n

Men ulemperne opvejes af de store fordele: den hastighed, hvormed emnerne kan fremstilles, lave arbejdsomkostninger, minimalt materialespild, og de f\u00e6rdige emner beh\u00f8ver ofte ikke mere efterbehandling.<\/p>\n
