Important note ..I have provided this reference information in good faith
that it is only used in initial design assessments. Material costs for
detail design must be obtained by contacting suppliers.
These costs are all based on Dec 2005 prices. I will modify this information in the first month of 2009
This page is includes information on the costs of different plastics used in mechanical
engineering. The costs are obtained by reference to links found on the internet (links 1,2 below).
I have converted the costs to english units although the costs are based on american costs in dollars and
imperial units. The costs are really only useful in as relative indicators. Real costs
depend on country of supply and market conditions.
Note: I am in the process of updating this information for early 2009. Typical adjustments are Nylon 66 is now about 50% higher than the table and ABS is about 30% higher based on minimum range prices. However current prices are all falling due to the world recession.
In order to try to arrive a reasonably practical costs for plastic components I have
obtained the cost of a representative plastic stock (a rod 50mm dia x 0.3m long).
This stock has an approximate volume of 0,0006m3.
This size has been selected because the stockist which are conveniently accessible on the internet,
generally provide costs in dollars /foot length with diameters in inches and the above size approximates to 2" dia x 1 foot long.
I have calculated the volume and weight and used these results together with the raw
material prices above to obtain the theoretical basic material costs.
These have been tabled below against the prices obtain from the internet (link 3 below) for rod prices.
