2 GM, the multipurpose machine from BILLION Production at the lowest cost, tending towards zero defect, perfect suitability to every type of application or cycle, the tremendous versatility of the GM range of injection moulding machines meets your needs for a wide scope of moulding processes. Generous platen dimensions allow use of voluminous moulds. DIXIT II control system with tactile colour screen : user-friendliness and security. 2 stage hydraulic clamping unit : simple, robust and rapid. Precise hydraulic locking controlled by pressure sensor. Modularity : choice from 3, 4, or 5 injection units for each clamping unit. 3 screw diameters per injection unit. Excellent cleanliness of the mould area is assured by the use of lubrication free fixed bearers under the tiebars to support the moving mass. Totally simultaneous machine movements and very high injection speeds thanks to the accumulator based hydraulic system.

3 Clamping unit principle Two small diameter cylinders displace the moving platen and the 4 locking columns to the fully closed position. The chock plate is driven behind the ends of the 4 locking columns and blocks the passage. (Position closed).the clamping cylinder transmits the clamping force to the mould via the chock plate bearing on the four locking columns. Rapid operation is assured by a particularly low oil volume requirement. Rear view of the chock plate Decompression of the clamping cylinder, followed by a minimal retraction stroke, allows the chock plate to disengage. (Position opened). The two cylinders pull the moving platen open to the desired opening stroke.the locking columns are displaced inside the clamping cylinder. Mould height adjustment The clamping cylinder stroke is used as the means for rapid and precise adjustment of mould height.the large cylinder can also be used to increase the initial opening force, for moulds that are difficult to open. Clamping cylinder and Mould height adjustment. Position OPENED Minimum mould height Position CLOSED Clamping cylinder Opening/Closing cylinders Locking columns Moving platen Fixed platen Maximum mould height Mould environment Rapid production changeover Large ejection box with simple access. Billion BC 500 Quick Mould Change. (Option) A wide opening stroke of the operator guard and the absence of an upper rail simplify mould change operations. Hydraulic and water connections can be distributed on the platens, with a robust caterpillar chain support for the moving platen (on request).

4 Hydraulic system and injection unit DIXIT II control system Hydraulic system Productivity and High performance :The hydraulic system with fixed displacement pump(s) and accumulators promotes high speed simultaneous machine movements.the energy stored in the accumulators satisfies peaks of oil demand, reducing the installed power requirement and energy consumption. Opening Closing Ejection return and forward Locking Unlocking Injection unit forward and return Injection Holding pressure Decompression Back pressure Screw rotation speed DP DP RP DP SD DP The GM range is equipped with the new DIXIT II control system : the well-reputed graphic concept of the DIXIT 500 has been reproduced and improved with this new version of DIXIT. More userfriendliness The colour screen is tactile on the complete surface. This enhances the ease of use of DIXIT. M Injection unit Precision and repeatability of the injection parameters are guaranteed by the closed loop regulation of pressures and speeds through a high performance servo-distributor. Efficiency Graphic or numerical representation; DIXIT II is able to adapt itself to everyone s working habits. Security SMART cards with user ID tags determine the access levels. The programming mode for such cards is integrated in the DIXIT II. Liberated core sequence programming DIXIT II responds to your needs for any imaginable core function sequence. Maintenance access to the nozzle and check ring assembly is simplified by the injection unit being mounted on a swivel base. Standard screws ranging from 20 to 25 LD are able to satisfy numerous applications. Specific screw profiles are available according to customer needs. Transfer of parameters The machine settings stored on a 3 1/2 floppy disk can be transferred to any other GM machine. The recalculation of parameters is effected according to the targeted machine characteristics.
