Definition of bullous. : resembling or characterized by bullae : vesicular bullous lesions.
Typical costs: Costs for complete installation of an encapsulation system start around $2,000-$4,000, average $5,000-$7,000 and can go as high as $8,000-$14,000 or more, depending on the size and condition of the crawlspace, local rates, and the materials used.
The costs would be computed as follows. Basic extrusion costs: A rectangle circumscribing the part would be 3â on a side, or 9 square inches in area. Hence, the die cost is $500 + 500(1) + 3(9) = $1027. Note that a blow molding die will always have a center cavity, and so H=1.The per unit cost in the basic extrusion model is just the material cost, which is the volume used costed out at the extrusion cost model.he volume of plastic in this part is 3.93 in^3 for the sides of the cone and .98 in^3 for the two ends. So the total volume of plastic is 4.91 in^3. Injection molding guideline gives us material cost of $0.9/kg (= $0.41/lb) and the specific gravity of .95.
