The detailed technical specifications for the new Coating Capacity Project are developed from the Basic Information developed in Parts 1 & 2 of this column. These are used to specify the technical and economic characteristics needed to specify the appropriate coating capacity. Multiple concepts should be considered to ensure that all needs are understood so the final capacity increase meets identified requirements.
Technical specifications for any project should indicate the goal value, priority and degree of difficulty to obtain each specification. For example:
General specifications for the project
- A coater yearly volume of 700 million sq feet of
final product for customer in the initial year of
new-capacity installation and increasing by 5%
a year for 10 years
- This coater volume has to be calculated based on coater-yield losses and other potential downtime.
- Multilayer-coating head for four layers
- Increase drying capacity in existing coater by
500 lbs/hr of solvent
- Web-handling capability for 0.50- to 10-mil substrate
- Reduced cost of manufacturing by 7%
Preferred location for new capacity
The location of the new coating capacity is an important variable that should be considered when developing the technical specs. There could advantageous reasons for building it in a new location. The current site could be inadequate because of a lack of space, insufficient utilities, high site costs or being located very far from product users.
Understanding of external technology
An understanding of the current technology that is available from hardware vendors and also being used by competitors is essential. This is needed to ensure that new capacity is competitive or superior to competitors. The new coater should use current technology to be effective. Some of the web-coating technical sources include:
- Technical societies, meetings and publications
- Web-coating-related books & Journals
- University research programs
