Injection moulding
Heralt, Aleš ; Balej, Zdeněk (referee) ; Žák, Ladislav (advisor)
This Bachelor´s thesis is focused on construction forms for injection of thermoplastic matters. The technology for plastic products production is technology that participate more and more in production of all sorts of products - from technical components over kitchenware after as much as toys. Main part of this thesis is focused on description of the injection valve, ejector, annealing and ventilation system forms for injection with the main structural principles.

Design of 3 axis manipulator
Štol, Michal ; Sýkora, Jan (referee) ; Holub, Michal (advisor)
This thesis deals with design of 3 axis manipulator which manipulate wit ball bearing and moulding of pulley. Moulding of pulley is product of injection press. Part of this work is also technical-economics valuation of manipulating possibilities with ball bearing and pulley and is determinate the most useful option. Next is work out a conception of conveyor for ball bearings and pulleys.

Production technology of plastic threaded adapters
Turek, Tomáš ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
The Master thesis deals with the possible production of the plastic unit with thread. As the most suitable material was chosen the polyformaldehyde (POM), its production label is Delrin 500P NC010 by Du Pont. The thesis consists of a part with the information about the technology of injection molding of plastics and a part where processing parameters for the production of the plastic unit are designed. Part of the solution was to create an assembly design of injection mold. Since the plastic unit with thread is very specificly shaped the form is handled as a slide mold. The mold is pieced together from normalized parts by the Hasco and DME company. The serie of 100 000 pieces would be delivered in 5 months. Because of the cost savings a solution of the cold-runner system was suggested. A suitable injection molding machine was chosen from the calculated values from Arburgfroms – Type 370s Allrounder 500-170.At the end of the thesis costs were evalueted for acquire per one piece of adapter.

Production technology of plastic carrier information
Krejčí, Radek ; Kebrle, Ondřej (referee) ; Kandus, Bohumil (advisor)
This bachelor's diploma thesis presents a proposal for the production technology of plastic carrier information, which is produced using injection molding technology. In the general literary study, plastic materials and injection molding technologies are analyzed. In the practical part of the thesis, the material of the plastic carrier information is selected. From the calculated technological parameters, the design of the injection mold is created and a suitable injection-molding machine is selected. Finally, a technical-economic evaluation is carried out, in which the cost of producing one piece of plastic carrier information is calculated.

Manufacturing process optimalization of high-volume plastic molded parts production
Grycz, Radek ; Dvořák, Milan (referee) ; Štroner, Marek (advisor)
This thesis deals with optimization of manufacturing process of plastic molded parts production. The first part focuses of describing current workplace, thanks to that was found out amount of transported materials. In second part there are two possibilities of solving problem with target to decrease amount of manipulations and transports. On base of this evaluation this these variants, the optimal variant is choosen. This variation improve molding process, decrease number of manipulation equipments and number of operators.

Design and assessment of a new paint line arrangement at Automotive Lighting
Bouček, Filip ; Hrbáček, Jan (referee) ; Píška, Miroslav (advisor)
The thesis deals with the design and arrangement of a new paint line at company Automotive Ligting s.r.o in Jihlava. It deals with design of several possible options of arrangement of machines that are required for the processing of polycarbonate granules and their conversion into acrylic glass using two-component injection molding. The glass is then coated with the coating line which is part of the arrangement included in this project. Design of the individual sites and their organization is based on both the company's requirements and the principles of technological design. The best of the three options is analyzed in detail and evaluated from the economic point of view.
