To explain all of the aspects of the problem we need 2,568,985 pages and a lifetime to write them all therefore this is a brief resume of the complete story.
Before you go in details and ask for an offer, you need to understand two things very well:
First is you need to state the quality level of the flakes you must have at the end.
Second, only by buy, may be the known fact you ought to be prepared to spend lots of money.
And this is what this means:
For instance a flake, very best for fibres application, can contain 20 PPM of glue and, if this is the quantity, your client will be very happy.
The same double screw extruder material with 10 PPM of glue may also be good, after pelletizing and SSP, for bottles application.
Therefore, the difference is 10 PPM equal to 0,001% - Got the point ?
This is not the only real difference because actually, again, the matter is a bit more complicated, but gives you a concept of what we're discussing.
At the end, the big difference stays in the price to get one quality versus another also.
If you ask for a good bottle to bottle quality washing line, the number you'll read within the last page will never have less than six zeros, and you're lucky if primary number is a 1, while for less quality the real number could be shorter, not forgetting the difference in operating costs.
This "small" difference may also effects the composition of the line in other sections.
Sorting, that is the very first area of the line, needs to be perfect, meaning zero PVC, PS, PA or perhaps other plastics cannot reach the granulator because following this true point these plastics cannot be recognized and removed. (yes, it can but is much too expensive)
Then, flakes go to air-separators to eliminate detached labels and most of the dirt, pre-washing, separation by sink-float tanks, the cleaning process, rinsing that's is usually another very important step of the procedure and final drying.
When you got all of this, you're half of the way to complete the setup.
In fact you have flakes clean to the bone with caustic soda solution, detergents and each one of these good stuff, that's actually pretty an easy task to feed to the line and, as a consequence, you need to eliminate it.
Water filtration is really as important as the washing line itself therefore.
A good filtration system(s) is why is the line to perform well, and contain costs, because in cases like this also, we are discussing hot water consequently energy costs are involved as well.
Next step is to transform your flakes into very clear pellets upgrading the product quality to the very best.
To know more about this, go to SSP page where is writeen likewise how to avoid the traditional SSP and get the same or better quality without losing weight and get it FDA approved.
