    System for managing construction part specifications

    Thank you all for your input. We indeed have a documentation system folder based but and with a seperate userinterface for accessing those documents. What I was looking for is more what 3DDave said, requirement management. For that we have the option sharepoint, team center from siemens but...

    System for managing construction part specifications

    Hi 3DDave, always happy with critical thinking :) Managing them for what purpose? - According to ISO9001:2015 the organisation should determine and control the requirements of delivered products (in line with the determined risk they pose if uncontrolled. That said, the specs for these critical...

    System for managing construction part specifications

    Hello, I'm want to know if anyone knows of a system for managing construction part specifications. I know that these parts for construction are designed in a CAD environment and that deminsions f.e. are stored in this environment. However in practice there is more to an part than only it's...

    Solution needed for sieving of small but long plastic material

    Thanks for the input, most helpful!

    Solution needed for sieving of small but long plastic material

    Yes that is used allso but after the grinding. PET and HDPE are grinded together. We need a way to sieve off everything smaller than 12,5mm (those long pieces not included) before it goes in the floatation tanks.

    Solution needed for sieving of small but long plastic material

    Hello, I'm in search of a solution for a sieving problem I have. In our process we sieve our material to be <12mm after grinding. The material is a plastic bottle (with cap). The as we all know just under the cap of a plastic bottle is a strip to secure the cap when the bottle is not used yet...

    Inline contaminant analysis on bulky product stream

    Thanks

    Inline contaminant analysis on bulky product stream

    The problem is that ppm based on counts does not equal the ppm based on mass because than the assumption is made that the contaminant has the same mass as the main product, which is not the case.

    Inline contaminant analysis on bulky product stream

    Maybe more easily said: I have the total product mass of the run. I have the ppm based on surface contamination count. I have the particle mass distribution of the contaminant. From these known facts I want to calculate the ppm of the contaminant based on mass for the total product run.

    Inline contaminant analysis on bulky product stream

    Hi all, I have a kinda headache exercize at hand here. I hope someone can look into it with me to find a posibble solution. Case is: I want to analyze contaminant ppmage mass based inline. We have a bulky product stream that goes over a weighing belt with a know speed and the weight that...

    Online analysis of colored plastic chips

    Hi all, I'm in search of a supplier in the range of the vision technology, online camera inspection, which can provide me a camera based system that will measure the number of different colors that comes by. The companies that I know of either have sorting devices or have handheld devices, but...

    Unclear points in ASTM D 1895 û 96 (2003) apparent density

    Dear all, Does anyone have experience with the standard in the title. The next points are not clear to me. Perhaps someone who implemented the standard already can clearify this for me. Test method C section 13.1 - It states “level the material”. Is there a standard way of levelling the...

    Determination of PE coating

    Hi all, Thanks for the support. We are going to try it first with a clear wash solution just above 70 degrees, to check as the supplier said if the laminate will turn loose. We wil check for floating material and if we can't see that, we will filter the wash solution to check for any PE...

    Determination of PE coating

    Thanks for your input Demon3, I see I didn't clearify it's about PET flakes. We wash it in a lye/detergent solution with a certain particle load that will rub the flakes. We tested the PE laminated (i got the info that it's a laminate instead of a coat) PET flakes on lab scale in this...

    Determination of PE coating

    Hello, At our plant we tried to wash PET with a PE coating (+/-10mu). With an oven test (melts) we tried to prove that the PE was removed or not, since the PET will melt and the PE will degrade in a brownisch colour. The oven test however showed some inconsistent results. We want a better...

    Define right model and test design approach for colour measurements of plastic flakes

    Hi all, I am looking for the right model and right test desing to use for the following case: I want to measure the colour of a flake material on a colour measuring device. There can be x (to be defined) different colours in the material. Standard material is blank. Each colour I can measure...

    Automated polymer identification on laboratory samples

    Hi Pat, I know of IR spectrophotometers but they can only handle a small quantity, like the size of a KBr tablet. I have talked with a supplier of Perkin Elmer during my internship at DOW benelux and they had an FTIR device that could show different color scales on a sample and each color...

    Automated polymer identification on laboratory samples

    Pat & Pad, Thank you for your posts. We have these systems in our factory however I want to know of small scale equipment specific for in a laboratory. At this moment we are inspecting the samples visually and we want to automate that. We want the QC inspection time down to a minimum and are...

    Automated polymer identification on laboratory samples

    Hi all, I'm in search of a piece of equipment which is able to identify different polymers between a bulk of PET flakes. I've been told such equipment exists but I don't know how and what and where to look. If possible, the idea is to have a sample of lets say 50g and spread is out on a...
