Equipment \ raw materials, test methods, scheme formulation, etc. Required for "plastic surgery". Please give me your advice. I appreciate it.

Production: weighing (weighing how much each additive is added), dryer (drying raw materials), mixer (mixing raw materials and various additives evenly), twin-screw granulator (main processing equipment, generally buy a screw machine, as well as granulator, blower, hopper, etc. ).

Testing: injection molding machine (making test pieces), universal tensile testing machine (strength, elongation, etc. ), solute test, toughness test, flame retardant test, color matching and so on.
