Abstract
V zadnjih desetletjih se je na najrazličnejših področjih našega življenju uveljavila uporaba plastike. Razlog za to je predvsem v njenih lastnostih in cenovni dostopnosti. Zaradi kompleksnih oblik se je pojavila potreba po spojitvi posameznih delov. Homogeno spojitev lahko dosežemo le z postopkom varjenja. Diplomsko delo je vsebinsko razdeljeno na šest poglavij. Najprej predstavim spojino polipropilen in postopek pridobitve polizdelkov. V drugem delu so predstavljeni različni načini varjenja umetnih mas in njihova področja uporabe. Tematika tretjega dela je izgradnja prvega stroja za varjenje enega samega izdelka. Razložen je postopek izračuna moči grelnih teles in ustreznih pogonskih sklopov. Zaradi potrebe podjetja po novem stroju za varjenje več različnih izdelkov sem v četrtem poglavju opisal razvoj večjega in bolj izpopolnjenega stroja. Osredotočil sem se na gretje, servo pogone, uporabniški vmesnik, varnost in delovanje. V petem poglavju se nahaja primerjava med strojema in nato sledijo še ugotovitve.

Title:Development of plastic welding machine for mass production
Abstract:
Because of its low price and qualities, the use of plastics is a big part of different areas of our lives. The need for fusing different parts has surfaced due to complexity of shapes. Homogenous fusion can only be achieved by welding. This thesis is divided into six chapters. At first, we look at compound polypropylene and the process of obtaining semifinished products. In the second part, different ways of welding plastics and their scopes are presented. The theme of the third part is the building of the first machine, used for welding only one product. The process of calculating the power of heating elements and relevant drive trains is explained. Because of the company’s need of a new machine for welding different products, in the fourth chapter, we explain the development of a bigger, more advanced machine. We focus on heating, servo drive, user interface, safety and operation. In the fifth chapter, there is a comparison between both machines, followed by findings.

Keywords:plastics, welding, polypropylene, heating, servo drives, user interface
