Duraclamp Cost Comparison
Duraclamp Assembly vs. Aluminum "C" Block with Aluminum Bolt
A. Material savings for typical anodizer* using Duraclamps®:
- Save over 5 cents per connection
- Save over $2,000.00 per month
B. Labor Savings for typical anodizer* using Duraclamps:
- Save 11 seconds per connection
- Save 117 hours per month
SPECIAL NOTES
- Cost comparison does not include costs to anodize (chemicals & power) aluminum “C” block & bolt on each run. Duraclamps are plastic and do not thieve any electricity or absorb any chemicals.
- Cost comparison does not include expense involved with the removal (or extra sewer charges) of additional aluminum generated from etching of “C” block and bolt. Duraclamps are plastic and leave no residuals that must be removed from the finishing tanks.
- Cost comparison is calculated for 1 shift only. If you work 2 shifts you should double the material and labor savings by utilizing Duraclamps®.
CALCULATIONS
A. Aluminum “C” Block with Aluminum Bolt- Material
“C” Block = $0.75¹/15 cycles = $0.05/connection¹ Bolt = $0.25²/03 cycles = $0.08/connection² Total = $0.13/connection - Labor
23 sec. – Fabricate aluminum “C” Includes: - Extrude “C” Block
- Initially tap and then re-tap for larger bolt
- Remove bolts from “C” blocks after they are no longer functional
- Melt aluminum “C” blocks after they are no longer functional
- General rack repair & maintenance
2 sec. – Tighten bolt each cycle 2 sec. – Disassemble bolt each cycle ———— 27 sec. Total
- Material
Clamp $3.57¹/100 cycle Clamp $3.57¹/100 cycle Stripping Workbar = $0.04/connection Total = $0.075/connection - Labor
8 sec. – Install 8 sec. – Remove —— 16 sec. Total
*Estimated usage (connections per month) for typical anodizer calculated as follows:
- Assume 20 pcs./rack = 40 connections for one complete rack
- 10 min. to rack (including down time – lunch, etc.)
- 8 hr./day x 20 days/mo. X 240 connections/hr. = 38,400 connections/month.
