Abstract
Minimizing changeover times are considered critical by manufacturing industries to
decrease non value adding processes, while at the same time being able to respond
to changing customer requirements quickly. It is a hard task to manage but in this
case a critical part was identified within a package manufacturing machine. The
goal was then to find out if this specific part could be redesigned to satisfy said two
needs, reducing changeover times and allowing new package designs quicker.
It was also an importance to know what manufacturing techniques are to prefer
when designing to shorten lead times. There are many conventional methods available
as well as upcoming ones when manufacturing parts. Different methods are investigated

Minimizing changeover times are considered critical by manufacturing industries to

needs, reducing changeover times and allowing new package designs quicker.
It was also an importance to know what manufacturing techniques are to prefer
when designing to shorten lead times. There are many conventional methods available
as well as upcoming ones when manufacturing parts. Different methods are investigated
in a literature study regarding manufacturing techniques and changeover.
The problem in this thesis was to identify and redesign the critical time consuming
changeover parts within a manufacturing machine. This thesis mainly used the well
known product development approach presented by Ulrich & Eppinger in order to
reach two among 25 generated design concepts. After said screening the two designs
were improved in several iterations and finally manufactured in a plastic material
called ULTEM1010 to be used when confirming the proof of concept.
Two tests were conducted, the first to determine if plastic parts was sufficient to replace
original metal parts since plastic parts can be manufactured much faster with
new techniques. The second test was performed to see if completely new products
could be produced with equivalent quality as the existing ones.
A completely new design of the machine part made it possible to use a modular
design were a "base-unit" is permanently installed in the machine. Each time a new
design is to be used a second part is attached to the base unit and secured with two
screws. The results clearly indicates that the plastic material ULTEM1010 could
be a replacement of the conventional metal in terms of its capability to form and
shape the package design. Although further investigation regarding wear, tear and
fatigue is needed before a definite answer can be made. A live test of the redesign
confirmed the proof of concept and that the solution is plausible, although some
further iterations might be needed for a enough satisfying result. (Less)
