Selleks, et välja selgitada millised plastitootmismeetoteid on võimalik töös olevate detailide puhul kasutada, uuriti lähemalt plastdetailide tootmise erinevusi ja nende iseärasusi. Sobivate vormi valikute tegemiseks tuli lähtuda algdetailist, mis oli toodetud just survevalu meetodil, kuid, et jääda võimalikult madalate kulude juurde ja luua detaile nii tööstuslikes kui ka mitte tööstuslikes tingimustes, siis uuriti lähemalt surevaluvormi, silikoon vormi ja 3D prinditud vormi loomist. Reaalselt valmis silikoon vorm ja 3D prinditud vorm, mille mõlemaga on võimalik kuni 100 detaili luua, kui tingimused on piisavalt head. Silikoon vormi on võimalik luua ilma arvuti ja masinate abita, kuid 3D prinditud vormiks tuli mudel valmis teha CAD programmis, et seda oleks võimalik hiljem printida, sellele lisaks kasutati 3D skänneri abi. Samuti selgitati välja toote omahind, et neid tulevikus suurema huvi korral toota suurem kogus. Kasutatud materjalide omadused on paremad, kui originaal detailil ja neist valminud detailide eluiga võiks olla vähemalt 5 kuni 10 aastat. Katsete tulemusena jõuti järeldusele, et toodetud epoksiidvaigust detail sobib antud sõidukisse, sest on üks-ühele koopia originaal detailiga ja süsinikkiust detail ei valminud tehniliste viperuste tõttu. Epoksiidvaigust detail sobib välimuselt sõidukisse paremini, sest näeb välimuselt ja katsudes saranane välja originaalile. Oletuste põhjal süsinikkiust detaili välimus ei sobi nii hästi antud sõidukisse, sest tegu on retrosõidukiga, mis on pigem vanamoodne ja aeglane, kuid originaal detaili asendamisega tuleks see toime, sest avade ja vormi mõõtude poolest sobib see originaal sõidukisseIn the course of the thesis, was made two different types of moulds which are possible to produce ZAZ 968 steering column cover. To sort out which plastic production methods was possible to use with these details, was examined in detail some plastic production differences and features. In the making of suitable mould the original detail had to be examined and draw conclusions that it was made with injection moulding method, but the moulds had to be cost efficient so we could examine the process of making plastic detail in industrial and non-industrial conditions. In this thesis the injection, silicone and 3D printed moulds were examined closely. Two mould types silicone and 3D printed mould was made, which both could be capable to produce upto 100 details if the conditions are near perfect. The silicone mould could be made without using any machinery nor computers, but 3D printed mould there had to be made CAD model which could be used to make mould in CAD program and for this 3D scanner help was used. Also every type of detail netcost was examined so they could be reproduced in the future if there would be more intrest. Used materials had better properties than original detail material and the lifespan of these details could be atleast 5 to 10 years. Experiments concluded the reproduced epoxy resin detail would fit the vehicle because, it is exact copy of the original detail and carbon fiber detail unfortunately was not produced. Epoxy resin detail would fit the vehicle better thanks to its looks and feel, because the material looks similar to original. Assumptions the carbon fiber detail looks won’t fit so well into the vehicle because it is retro vehicle which looks old-fashioned, but the carbon fiber looks are more like futuristic. To replace the original detail with the carbon fiber detail it would fit, because the holes and mold parameters are right.etVormidSalongi detailidAutotehnikalõputöö
