Kostnadsbesparingar på EM7 : Omkonstruktioner för billigare tillverkning

This thesis describes how a cost reduction project was done on the Packsize ondemand packing machine EM7. The cost reduction was achieved by making minorredesigns of the EM7.The project began by studying the EM7´s structure and function by working on itsassembly line. A short literature study on the subject Design for Manufacturing wasalso done.By working on the assembly line and by speaking with staff from production anddevelopment departments, a number of ideas for reducing manufacturing costs arose.Estimations of the potential cost reduction size for each proposal were done incollaboration with vendors and the purchasing department. Based on the size of the cost reduction, technical risk, impact on the assembly lineand the development time the various proposals were ranked. The two highestranked proposals were selected for further development towards finished solutions.One of the ideas that were selected to develop in to a finished solution meant thatsome of the pneumatic valves were replaced with others.

Customer Relationship Management : Hur ser behovet av CRM ut för små och medelstora tillverkande företag i Sverige?

An increasingly globalized market is leading to hard competition among manufacturing companies, which means that they are forced to become more customer focused to survive in the market. A Customer Relationship Management system is a system that will be of assistance to help companies succeed in building long term relationships with their customers. Best of Breed and ERP-based are two types of CRM systems. The study has focused on analyzing and examine the need for CRM systems at manufacturing companies. Our question formulation has been:? What need do businesses want to satisfy with a Best of Breed-based and ERP-based CRM system?? Are there any differences in the use of Best of Breed-based and ERP-based CRM system?In this study, we have chosen to carry out interviews and quantitative surveys with manufacturing companies to get their view of CRM-systems.

The overall purpose isto increase performance of the sailing boat.The task for this thesis was to develop a concept of keel blade in composite material and investigateattachment to a sheet-shaped element.

Design for Manufacturing : för produktionsanpassad konstruktion på Volvo Aero

Målet med examensarbetet var att skapa ett verktyg för insamling av erfarenhetsdata för produktutvecklingsprocessen. Den skall vara användbar för att bidra till ett systematiskt arbetssätt för produktionsanpassad konstruktion på Volvo Aero Corporation. Det skapade verktyget för insamlande av erfarenhetsdata skall bidra till att produktivitet och producerbarhet kan förbättras på kommande koncept och konstruktioner. En förstudie har genomförts på företaget under hösten 2010 vilket ligger till grund för det beskrivna problemet i examensarbetet.Arbetet avgränsades till att utveckla en struktur för hur metod och erfarenhet skall struktureras och en testversion av verktyget togs fram för utvärdering. Efter samråd med den handledande Verksamhetsutvecklingsgruppen, VU-gruppen, från avdelning 9931 Projekt-, Koncept- och Tillverkningsledning, beslutades att examensarbetet skulle avgränsas ytterligare till insamling av diametermått på komponenten Diffuser Case på Volvo Aero.

Identifikation av produktionsstörningar och obalanser vid tillverkning av golvskenor

Our report procedure identification of instability and disturbance in an automatic manufacturing line of processing and assembling of chair sliding rails at Sapas manufacturing department in Vetlanda.To obtain a stabile ground we have mapped the material flow to receive a comprehensive view and to visualise connections.We have examined cycle times at different stations in purpose to identificate bottlenecks. The result of our examination showed that the bottleneck of the line was the brush station. This leads to that the expected bottlenecks identificated by Sapa gets a delay time and by that a longer cycle time.Interruptions has a clear negative influence at the line performance so we have also assemble data through the operators report list and compiled these in order to find out the interruptions effect on the line. The outcome during our assembled period was that the reported interruptions corresponded about 30 percent of the total available production time. This has a clear negative effect on the line productivity and efficiency as we have calculated in order to get the present status..

PLM-SYSTEM FÖR TILLVERKANDE MINDRE FÖRETAG : EN STUDIE OM LÄMPLIGHETEN AV PLM-SYSTEM OCH FÖRANKRING GENOM CHANGE MANAGEMENT

This study aims to investigate how small scale manufacturing companies reason around an implementation of a PLM-system, as well as the suitability of these systems compared to larger companies. The study is built on a qualitative method. Initially, secondary data was gathered through books, articles and reports. Primary data was gathered through four interviews. Two interviews were performed with PLM resellers, one interview was performed with a PLM developer, and one interview was performed with a small scale manufacturing company that opted to not implement a PLM-system.The results imply that overall differences between larger and smaller companies exist in regard to the need of PLM systems.

Metallersättning inom byggbranschen

In this paper the possibilities to replace metal with plastic in products for the building industry were looked into. The first part was a market examination where several suitable products were found. After evaluation the door latch for in-house doors was selected to be re-designed to better suit the properties of plastic.New types of mechanisms were designed with different functions that use the benefits of plastic materials. Models of these mechanisms were developed to evaluate their function. The components in the different mechanisms were adapted for manufacturing with injection moulding.To confirm that the plastic material could handle the appearing stresses calculations on the most vulnerable parts were carried out.

CE-ma?rkning av produkter under byggproduktfo?rordningen

The purpose of this study is to achieve an understanding of how a CE- marking process is conducted and to identify the relevant factors that must be considered in such a process. We have conducted our study at Lo?vhults Svets & Smide AB (Lo?vhults) in Skruv, Sma?land Sweden, which are manufacturing brackets for small covering constructions.To understand how a CE-marking process is conducted several documents and provisions have been reviewed to achieve a basic understanding and insight of the subject. It thus led to that guideline ETAG 015 were studied and the factors to be considered in the CE-marking of brackets were identified. Together with Jan-A?ke Johansson at Lo?vhults we agreed on four different brackets to investigate for a potential CE-marking.

Konstruktion rörklammer

This report describes the development process of a pipe clamp used on exhaust system for cars. It is made based on the manufacturers desire to improve and make the clamp easier to manufacture and to reduce its price to their customers. This should be done either by manufacturing the clamp in one piece without an expensive and work intensive welding process, or by generating ideas of how to develop a brand new type of clamp. Investigating the market for similar products was done to eliminate intrusion of other manufacturers? patents but also to generate ideas.

Outnyttjad kreativitet och kompetens inom produktion : - Ett arbete som fokuserar på att fånga upp och ta tillvara på medarbetares kreativitet och kompetens

AbstractResource efficient manufacturing is a term that has been increasingly applied within manufacturing, where one of the key points is to reduce waste of such forms that do not add value for the end customer. By the Lean principles, there are seven plus one types of waste, in which the definition of the eighth point varies among sources. In this study, the eighth type of waste has been interpreted as the untapped creativity and competence among employees that has not been put to use. From this, our question was incubated; How can you make the most of the employees? untapped creativity and potential within manufacturing? The case study will be developed with empirical data obtained from Dometic Group by conducting interviews.From the gathered literature, it was concluded that the communication between employees contributed to an increased understanding of one another as well as it allowed for improvement in work.

Design och konstruktion av Splitmaskin

During springterm 2010 Erik Persson and Magnus Hansson performed their ThesisWork with DIAB Laholm, in Hallands County for University of Halmstad.The project has been a product development project without exterior customers. Thusit had a great emphasis on functionality and less emphasis on marketing and such.This reflects the ambition to develop machinery to be used within the productionfacilities of DIAB Laholm, not to be sold to exterior customers.Main objective has been to create machinery which enables the production ofrotational symmetric work pieces within a NC-milling machine with 5 axles. Thework pieces milled will be made of DIAB?s material Divyncell with varyingdensities.The project has followed Fredy Olssons method involving Principal ? Primary ?Manufacturing constructions. However a complete manufacturing construction hasnot been made since DIAB just wanted a good Primary construction which will serveas a base for finishing touches at DIAB.By the end of the project material including calculations has been sent to DIAB andthey will finish the work and manufacture the machine if they find economic viabilityin this.The work method has been suited for this by several reasons, it was created withthese projects in mind and it?s also the method most familiar to us..
