Production single parts from thermoplastic
Enekeš, Lukáš ; Kandus, Bohumil (referee) ; Žák, Ladislav (advisor)
The project elaborated in frame of engeneering studies branch 2307. The project is submitting a design for production technology for a plastic part- bottom end of table leg made of polyamid Pa- 6. Pursuant to the literary pursuit of the problem production issues on the technical plastic segments by the technology of the injecting of a plastic into the mould (by injection mould technology). In the first part devision and identification of plastic materials are described. In the next part technological parameters and a design of the manufacturing machine and tool, including a drawing documentation, are determined. In the conclusion a simple calculation of the production costs is carried out.

It concerns with the proposal for production of specified plastic part made from material PA66-GF30FR using injection modling technology. In the introduction is summary of current production status and description of basic plastic properties, principles of injection molding, injection modling machine and injection mold. In practical part is solving of mold design. In conclusion is the simple economic assessment of costs and benefits.
Design of manufacturing technology for car carpet
Kavan, David ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
The main goal of this bachelor thesis is design of a manufacturing technology for car carpet made from a thermoplastic elastomer. Car carpet will be produced by injection molding with a hot runner system in a series of 42 000 units per year. At first there is an analysis of the current technologies, enclosed with a summary of reasons for the changes in manufacturing technology. Then following is a general review of the literature relating to plastic materials and injection molding technology. In the practical part a suitable material is chosen, injection molding machine is chosen according to calculated technological parameters and a conceptual design of an injection mold for car carpet is executed. The last part is a technical and economical evaluation comparing the current production technology with the newly proposed technology.
Production technology of plastic parts for automotive industry
Šobáň, Jakub ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
The diploma thesis presents a production technology design of an automotive industry component – a resonator holder. The initial production run of the part is 500 000 pcs. Injection production has been selected based on variant analysis of available technologies. Technological calculations have been performed. The selected material PP 56M10 will be used for operation in granules. A quadruple shaped cavity injection mold with a tunnel gate has been designed. Based on estimated technological properties an Arburg Allrounder 470 A machine has been selected. The break-even point (BEP) shows economic return at the production of 185 595 pcs.
Manufacture of AC / DC adapter housing
Vašíček, Lukáš ; Ohnišťová, Petra (referee) ; Žák, Ladislav (advisor)
The bachelor's thesis proposes an injection mold for the production of a plastic adapter. Based on the evaluation of the technological possibilities of the production of a plastic product, the technology of plastic injection was chosen. The first part of the work is devoted to a theoretical explanation of plastic materials, injection molds and machines. The practical part presents and develops a complete design of the injection mold, including the selection of a suitable material. The mold is designed four times with a cold inlet insert. At the end of the work is a technical - economic evaluation of production.
Production of joint folded out the rule
Šoukal, Hynek ; Podaný, Kamil (referee) ; Žák, Ladislav (advisor)
Project developed within the bachelor study presents a proposal production technology of joint folded out the rule from construction steel 12 060. Thick is 0,5 mm and the production ran is specify at 30 000 units a year. In accordance with literature studies and by calculations have been designed a combined roll forming tool, which consists of a rack with two pillars. This tool will be fix in on eccentric press LEN 10C by SMERAL, Trnava, with nominal press force 100 kN. Trimming punches, holding punch and bending puch are made of tool steel, grade 19 436.3. Lower functional part of the tool ass well.
Design of manufacturing technology for plastic terminal device
Adamiec, Pavel ; Žák, Ladislav (referee) ; Kandus, Bohumil (advisor)
The master thesis deals with design to produce terminal using the plastic injection molding. In the first part are theoretical information about injection molding and injection molding with inserts. The second part is a concrete design of production terminal which contains: injection mold design, calculation of the injection parameters, machine selection, technical and economic evaluation of production. Terminal is made of polyamide 66, inserts material is brass. Parts of injection mold assembly are selected from Hasco standards. The main parts of assembly are made of 1.2312 steel. Production cycle is placed on injection machine Allrounder 375 V from Arburg.
Design of Tool for Louvers Production
Hejna, Jaroslav ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
This thesis presents a tool design for production of embossments into the bottom part of the agricultural silo made of Dx51D material. The research analysis all technologies used for embossing, that is cutting and shallow drawing. This is followed by a chapter on simulation. The tool design itself is described. Its principle is based on tools for punching machines. The upper half of the tool is composed of a weldment to be clamped into pressing machine, into which are mounted functional parts in the form of inserts. The lower tool consists of several bolted plates, punches and a holding plate, which is located on the springs. In order to achieve correct design, necessary calculations were carried out and it was all confirmed by simulation in ANSYS. The two tool halfs are guided by pins attached at the edges of the lower tool. The technical - economical evaluation compares the work of the proposed tool with other possibilities of embossing.
Manufacturing of a Cable Holder
Šimka, Radek ; Žák, Ladislav (referee) ; Řiháček, Jan (advisor)
The bachelor’s thesis proposes a design for the production technology of the cabling holder, situated in the outdoor part of the air conditioner. This product is made of steel sheet DC01 with a thickness of 1 mm. The production of this holder is set to be 200 000 pieces per year. A progressive die tool was selected as the most suitable type of production technology, based on a literature study of various production technologies. This enables to combine cutting and bending of steel sheets with the use of one tool device. Manufacture will be performed using a mechanical eccentric press LEN 63 C. All the necessary requirements of this device are satisfactory for the production.
Forming Technology of Thin Sheets
