| dc.description.abstract | Antud lõputöö eesmärk oli koostada kliendile toote, survevaluvormi ja stantsi hinnapakkumised ning võita pakkumine. Lisaks tuli välja töötada optimaalne tootmisprotsess Plastoteci masinapargile. Töö käigus arvutati vajaminevad survejõud, leiti parameetritele vastav survevalu masin, mis on seeriatootmise jaoks piisav ning arvutati tööde aja- ja kulunormid ning maksumus. Töö käigus selgus, et stantsi suurused ei ühti olemasolevate toodete suurustega ning seetõttu oli vajalik tellida uute näidiste järgi sobiva diameetriga stants. Vormile teostatud modifitseering raadiuselt täisnurkseks aitas kaasa toote tsentreerimise stantsi pesas, kuid ei parandanud üleüldist diameetri viga. Kvaliteedikontrolli käigus avastati, et sisse ostetud filterriide materjal muutus poole toodangu käigus. Materjali muutuse avastamine toimus tänu mõõteprotokolli teostamisele, mis ennetas saatmast praaktooteid kliendile. Suurimaks tagasilöögiks oli Hiina näidiste mitte ühildumine valmis olnud stantsi mõõtemetega. Seda viga oleks saanud ennetada, kui vorm ja stants oleks tellitud ühelt ja samalt tootjalt või kui stantsi valmistamist poleks alustatud enne, kui Hiina näidised on jõudnud Plastoteci. Kokkuvõtlikult saab öelda, et antud töös läbiviidud analüüsi ning arvutuste tulemusena oli võimalik saavutada püstitatud eesmärk. Hanke pakkumine võideti ning uus, stabiilne ja võimalikult efektiivne töökorraldus töödati välja ja rakendati. Hetkel Eestis puudub koolitusasutus, mis tegeleks plastikute edasiarendamise ja sellega seotud teadmiste õpetamisega. Plastoteci juhtkond väidab, et antud valdkonnas kompetentseid spetsialiste on Eestis väga raske leida ning seetõttu tuleb ettevõttesiseselt inimesi koolitada, et suurendada nende teadmisi plastiku valdkonnas. | |
| dc.description.abstract | The purpose of this thesis was to prepare product, injection mold and die price offers for the customer and win the offer. In addition, an optimal production process for Plastotec's machinery had to be developed. During the work, the required compression forces were calculated, an injection molding machine that matched the parameters was found, which is sufficient for series production, and the time and cost norms and cost of the works were calculated. During the work, it turned out that the sizes of the die did not match the sizes of the existing products, and therefore it was necessary to order a die with a suitable diameter according to new samples. Modifying the mold from a radius to a right angle helped to center the product in the die slot, but did not correct the overall diameter error. During the quality control, it was discovered that the purchased filter cloth material changed halfway through production. The discovery of the change in material took place thanks to the execution of the measurement protocol, which prevented sending scrap products to the customer. The biggest setback was that the Chinese samples did not match the dimensions of the finished die. This mistake could have been prevented if the mold and die had been ordered from the same manufacturer, or if the production of the die had not started before the Chinese samples reached Plastotec. In summary, it can be said that as a result of the analysis and calculations carried out in this work, it was possible to achieve the set goal. The tender was won and a new, stable and as efficient as possible work organization was worked out and implemented. At the moment, there is no training institution in Estonia that would deal with the further development of plastics and the teaching of related knowledge. The management of Plastotec claims that it is very difficult to find competent specialists in this field in Estonia, and therefore people must be trained within the company to increase their knowledge in the field of plastics. | |
