What Is L/D ratio in injection moulding machine
WebbThe injection molding operation is usually carried out by a single machine. There are three major types of injection machines in the rubber industry (Figure 1): the ram type, the in-line reciprocating screw type and the out-line non-reciprocating screw type. 5–9 At the present time, ram-type machines are not widely used due to difficulties in achieving homogeneity … WebbInjection speed mm/s 200 - 270 - 350 Screw Range Ø (mm) Ø 32 – up to Ø 52 Shot capacity (cm3) 121 – up to 442 Screw Geometries Various to suit your process requirements Machine Dimensions (L x W x H) (m) 5.5 x 1.4 x 1.7 Wide range of FANUC Roboshot standard features university of wisconsin physics museum
