Requirements
The assembly holds a jigsaw blade while the pusher Tube is moved up and down by the jigsaw’s motor. Potential production methods were machining of steel, Al- and Zn-die casting, steel precision casting and MIM.
Benefits
While machined steel gave the required precision and strength but was too costly. With Zn- and Al-die casting cost was favourable but strength and/or precision was inadequate. Precision casting was able to meet the strength and cost requirements but could not meet the precision requirement. In the end only MIM met all the requirements.
