This thesis deals with the surface of kitchen worktops. There are evaluated the physic-mechanical properties, chemical properties, ecological properties and also utility and visual properties of some selected worktop materials and decors. There are also analysed the requirements to worktop surfaces. In this thesis are verified these physic-mechanical and chemical properties and utility - resistance to cold liquids, resistance to wet heat, resistance to dry heat, resistance to falling ball and determine the surface hardness, surface gloss and colour shade of surface. Appropriate test were applied on these worktop materials - laminated worktop, compact laminate, Solid Surface (Technistone), Quartz Surface (Avonite) and granite.

This thesis is aimed at a very detailed process of a transparent plexiglass used for manufacturing an upstand of a gramophone. The diploma work is mainly focused on various types of the plexiglass, its attributes and the gramophone’s upstand production. Several manufacturing technologies of a plexiglass such as division of a board-type semi product, precise milling, grinding, polishing and thermal treatment are provided in this diploma work through a very detailed description of a production process of a gramophone’s deck. The outcome of this thesis is a description of individual technologies and the economic evaluation within the real business environment of AZ Plastik company.
