Different process has been used to produce micro needles such as Deep Reactive Ion (DRI) etching, micro injection molding , Droplet born Air blowing (DAB) and Stereolithography. I want to know about the cost of producing these needles from different process.
Thanks.
To do a reasonable job of estimating manufacturing costs for different processes used to produce a product I would suggest you develop a manufacturing cost model for each process type. To start, you will need to be able to define the finished product design and tolerances required, critical to quality attributes, and final product configuration. (Different process types can have dramatically different tolerance capabilities and can require dramatically different downstream processing.) Then for each process type create a theoretical process flow to go from raw materials to finished part. Once the model(s) are created you can start to change variables (material type/cost, rates, etc) and develop a reasonable estimate of manufacturing cost. Using the models you can then develop a statistically based mfg cost answer and also do sensitivity analysis.
If you look only at the cost of producing a pound, square inch, etc of needles you may find that does not estimate the total manufacturing cost because other process step costs dwarf the cost of producing the needles themselves.
