NOVELTY - The utility model claims a graphene polymer melt differential moulding device, the device comprises an injecting system, micro forming system, a mechanical arm system and mould system. In the utility model, the polymer material through the hopper into the injection system, by the melting of the injection screw rod and heating ring plasticizing, melting and then the front barrel is injected into microsphere moulding system; two spiral roller rotation of the microsphere forming system the front end conveying quantitative differential melting material into microspheres of uniform size and shape, and conveying, the forward end of the spiral roller by extrusion, and then the mechanical arm system clamped, placing the next mould cavity centre, then bottom die rotates clockwise one station. pressing head downwards pressing melt to obtain product. because of using differential ball compression, there is no gate material piece is to avoid double refraction defect; the microsphere by mechanical arm system clamped to the midpoint of each die cavity, ensures the size uniformity.
