Investigation of Manufacturing Method for Odd-holed Plates for Gasketed Plate Heat Exchangers
(2023) MMTM01 20231Production and Materials Engineering
- Abstract (Swedish)
- Den här rapporten undersöker samt jämför det möjliga användandet av olika tillverkningsmetoder i produktionen av varianthålade plattor vid Alfa Lavals produktion i Lund. De tre metoderna är stansning med excenterpressar, abrasiv vattenskärning och laserskärning, där de två förstnämnda används i Alfa Lavals produktion i dagsläget. Syftet med projektet är att förkorta ledtider, genom att hitta en metod som är effektiv och flexibel. Information, både teoretisk och praktisk, har samlats genom litteratur- och fältstudier, vilket inkluderar intervjuer med externa experter, för att få djupare insikt i de tre metodernas lämplighet för den aktuella processen. Under projektet undersöktes ett antal parametrar, så som effektivitet, arbetsmiljö, både i... (More)

Syftet med projektet är att förkorta ledtider, genom att hitta en metod som är effektiv och flexibel. Information, både teoretisk och praktisk, har samlats genom litteratur- och fältstudier, vilket inkluderar intervjuer med externa experter, för att få djupare insikt i de tre metodernas lämplighet för den aktuella processen. Under projektet undersöktes ett antal parametrar, så som effektivitet, arbetsmiljö, både i form av säkerhet och renlighet, kostnad, kvalité och miljömässig hållbarhet. En analys, baserad på den insamlade informationen och dessa parametrar, genomfördes, vilket resulterade i ett poäng för varje tidigare nämnd metod. Baserat på intern värdering hos Alfa Laval viktades dessa parametrar på en skala av 1-5, beroende på hur viktiga Alfa Laval anser dem vara, där 1 innebar minst viktig och 5 innebar mest viktig. I och med analysen framkom laserskärning som den mest lovande tillverkningsmetoden, främst tack vare dess flexibilitet, säkerhet och låga underhållsbehov, trots vissa problem med kvalité, vilket skulle kräva vidare tester. Abrasiv vattenskärning bedömdes som den näst mest lovande metoden, vilken var metoden med den lägsta totalkostnaden, men där det höga underhållsbehovet, mängden efterarbetet samt dåliga ergonomiska förutsättningar minskades dess poäng. Stansning med excenterpressar fick den lägsta poängen, där höga kostnader på grund av verktyg och verktygsunderhåll samt längre omställnings- och ledtider var stora faktorer, trots att kvalitén som fås med metoden generellt är mycket hög.

- Abstract
- This report investigates and compares the possible use of different manufacturing methods in production of odd-holed plates at Alfa Laval’s site in Lund. The three methods are punching with eccentric presses, abrasive water jet cutting and laser cutting, with the first two being used currently at Alfa Laval. The aim of the project is to shorten the lead times, by finding a method that is efficient and flexible. Information, both theoretical and practical, was gathered through literature and field studies, including interviews with external experts, to obtain further insight into the three methods’ suitability for this process.

Information, both theoretical and practical, was gathered through literature and field studies, including interviews with external experts, to obtain further insight into the three methods’ suitability for this process. During the project, a number of parameters were investigated such as efficiency, work environment, both in terms of safety and cleanliness, cost, quality and environmental sustainability. An analysis, based on the gathered information and the important parameters, was conducted, resulting in a score for each mentioned method. Based on internal valuing at Alfa Laval, the parameters were weighed on a scale of 1-5, depending on how important Alfa Laval considered them to be, with 1 being the least important and 5 being the most important. The analysis found laser cutting to be the most promising option, mostly thanks to its flexibility, safety, and low need for maintenance, despite some issues regarding quality, which would require further testing. Abrasive water jet cutting was deemed the second most promising, which was the option with the lowest cost, where the high need for maintenance and post-processing as well as poor ergonomic conditions decreased its score. Punching with eccentric presses received the lowest score, with high costs connected to tools and tool maintenance as well as longer set-up and lead times being major factors, even though the quality that comes with the method is generally very high.
