Standard Operation Procedure (SOP)

The Proofing Process shown above is also defined as "colour matching"  in which it helps to generate colour cards that are identical to client's sample or that meet our customers' specific requirements based on a given formula.  Sophsticated skills and  technology enables us to precisely select the right colour, delivering the best outcome for your application.

Our full array of lab resources includes:

• Colour spectrometers

• High pressure liquid chromatography (HPLC)

• Fourier transform infer red spectrometers (FTIR)

• Film and sheet extrusion line

• QUV accelerated weathering tester

• Filter pressure equipments

• Densitometer and volume resistivity meter

• Moisture tester

• Melt flow indexers.

Production Procedure includes:

Step 1:  Pouring the  required raw materials (such as polymer, pigment and dispersion additives) into the extruder with the right dosage, then, feeding the bath-oid Premixs into the Premixing contain mixer, and finally mixing them into the perfect status .

Step 2: Feeding the finished  Premix  into the melting machine, melting at perfect temperature and stranding  finished  Premix through strand  granulation system.

Step 3: Extruding and drawing the strand, MFI: 35g/10min. 

Step 4: Cooling the strand.

Step 5: Cutting the strand into granules/ Pelletization .

Step 6: Discharging.

Step 7: Screening the 2.5mm granules by the strainer.

Step 8: Weighting 25kg/bag.

Step 9: Packing into Water-proof and vacuum bags.
