            Plastic Extruder Tips 10: Color Masterbatch Formulation Research                           Color Masterbatch Formulation Research When you get an order from your customer for a new color masterbatch, if you have no experience, you need to research the approx. formulation first. So actually, the most important thing is you have a good color blending engineer. Now we example as PE-based red color masterbatch: Before we start the formulation, we should know the application of color masterbatch, like injection machine using or blowing machine using. Because of that the requirement of pigment dispersibility and moisture, blowing machine > injection machine, especial for high pigment filling masterbatch.  As we know, the color masterbatch is made by Carrier(PE) + Pigment (red color) + Additives (dispersant, lubricant, anti-UV etc.) + Filler material (som...

This formulas will come in handy if you are working in a plastic woven sacks manufacturing unit as production manager Formulas Picks per minute = cam RPM x Number of shuttles Weaving Ring I.D = 2 x fabric Dfl. (mm) OR = 2 x fabric Dfl. x 25.4/ 3.14 (inch) Elongation = Increase in length x 100 / Initial sample length Number of warp = 2 x fabric Dfl x Warp Mesh (Inches) = 2 x fabric Dfl x Warp Mesh /10 ( Fabric Dfl = centimeter, Warp Mesh= DM ) Fabric Production = 1.54 x pick/minute/Weft mesh (inches) = 6 x pick/minute/weft mesh (DM) Fabric GSM = Warp mesh x Warp Denier + Weft mesh x Weft Denier/228.6 Bags Weight = 50.8 x fabric Dfl x Cut length x Warp mesh x Warp Denier + Weft mesh x Weft Denier/ 90,00,000 = Fabric Dfl. x Cut length X GSM/ 5000 ( warp mesh and weft mesh in inches, fabric dfl and cut length in inches) » For PP Unlaminated Fabric For Example, If you want to Produce 60cm x 90cm single fold bottom stitch 90 gram bag. For Production you n...
