What is bulk material? Coil processing plant - Elsmar Cove

We are a coil processing plant that does work for suppliers of the big 3. Our coils range anywhere from 8,000 to 60,000 lbs. when shipped. My question is this. Are we considered a "bulk material" subcontractor and need to follow the criteria in the new 3rd edition of PPAP for bulk material (Which seems slightly easier and closer to what we do)? One last thing. The coils are given a production number from the customer. Does this automaticly make it production material and the standard PPAP needs to be performed?
Please help. Dewie's right. You are NOT a bulk supplier. You MAY BE and most likely are a raw material supplier. Yes, you are subject to PPAP if you are gearing toward QS-. After all, you are responsible for ensuring consistent chemical, metallurgical, and physical properties from coil-to-coil and shipment-to-shipment. The purpose of this is so that the users of the steel can be assured that their product will come out the same time and time again. I'm sure we all know what variations in our raw materials can do to us. If you have selected a registrar already, ask your registrar. And of course, you can always ask your customer to determine their expectations. For, no matter what any of us write here, if your customer wants "it" a certain way, that's the way! Re: What is bulk material?

I am referring to 4th edition of PPAP manual. It does not say that coil is an example of a bulk material.

Per the manual these are the examples of bulk material.

Examples of bulk material include, but are not limited to: adhesives and sealants (solders, elastomers); chemicals (rinses, polishes, additives, treatments, colors/pigments, solvents); coatings (top coats, undercoats, primers, phosphates, surface treatments); engine coolants (antifreeze); fabrics; film and film laminates; ferrous and non-ferrous metals (bulk steel, aluminum, coils, ingots); foundry (sand/silica, alloying materials, other minerals/ores); fuels and fuel components; glass and glass components; lubricants (oils, greases, etc.); monomers, pre-polymers and polymers (rubbers, plastics, resins and their precursors); and performance fluids (transmission, power steering, brake, refrigerant).

Hope it helps to all fellow coves !

Emphasis added. It always pays to read what you're quoting. Re: What is bulk material?

As an auditor, I would accept that this phrase - fabrics; film and film laminates; ferrous and non-ferrous metals (bulk steel, aluminum, coils, ingots); - could apply to bulk, master coils. I would not apply it to slit final coils, without some further discussion and review. Re: What is bulk material?

As an auditor, I hope you would honor what the standard clearly says, and not your own interpretation of it. I think that coiled metal is an appropriate member of the bulk material population, because there's usually no way to sample anything other than the ends until it's too late, whether the material has been slit or not.

Coil processing has a long list of advantages that make this kind of supply much more convenient than the traditional sheet metal processing, specifically from two main standpoints: higher saving of raw material and higher production speed.

What is coil processing?

Coil processing machines allow cutting on raw material, optimizing its use: thanks to the nesting of the figures on coils without a length limit, we can produce a higher number of pieces than if we were working with previously cut metal sheets, reducing waste by 20-30%. Less waste and more pieces produced: with the same surface area, the coil nesting allows to make better use of the raw material available.

This implies two great advantages:

• The first is to be intended in terms oftime saved, considering that you don’t need any extra time to cut the metal coil into sheets;
• The second one is in regard tohow much money is saved, considering that coils have a lower cost than metal sheets.

Therefore, coil processing allows to reduce waste material and purchase costs, while increasing productivity in terms of the number of pieces produced.
 

Coil processing

Thanks to the automatic feeding system, coil processing allows a highly increased production speed. Coil processing doesn’t require constant loading and unloading operations of metal sheets into the machine, which causes a great cut in regards to the time needed to load and unload raw material.

Besides being extremely more effective, coil processing is also more sustainable than the traditional sheet metal processing, because it allows to use less raw material and it requires to change wearable pieces with a lower frequency, thanks to direct-drive engines.
 

How are steel coils processed?

Steel coils must undergo a multi-step procedure to ensure the quality and polyvalence of their intended applications. 

• Firstly, raw steel is purified, melted, and alloyed to achieve the desired properties. 
• Then, is the turn of thehot rolling processwhere molten steel is formed into a continuous slab and rolled into thin sheets exposed at high temperatures. 
• Theserolled sheets can undergo further processing, such as cold-rollingto achieve tighter tolerances and better finishes. In order to shield the sheets and enhance their corrosion resistance, it is possible tocoatthem with zinc.
• After rolling and finishing, thesheets are coiled up. 

Throughout the entire coil processing procedure, quality checks are carried outto ensure the steel meets specific industry standards.
 

Coil processing lines

Produtech’s coil processing lines work automatically on the entire productive cycle, from raw material to the finished piece, without the constant supervision of an operator or the need to manually reposition the pieces from a machine to another.

This implies a higher level of automation and performance of the productive processes, with less need for either economic or manpower resources in order to carry on with production.

Also, coil processing implies a reduction in terms of hazardous emissions: Produtech’s coil processing lines do not emit CO2 and operate in almost complete absence of fumes generated by liquid lubricants.
