What Are Injection Molding Machine Specifications

Injection Molding Machine`s Specifications mostly includes four units: Clamping Unit, Injection Unit, Hydraulic Unit, and Electric Unit. And there are many main index parameters in each unit.

What Are Injection Molding Machine Specifications

All brands of injection molding machines should list this index parameter for buyers’ information to select the right machine. No matter it is Husky, Toshiba, Nissei, Engel, JSW, Toyo, Haitian, Sumitomo, Mitsubishi, Arburg, Battenfeld, LG, CLF, Windsor or Demag injection molding machine.

While selecting an injection molding machine, you must understand and value of the specifications of plastic Injection Molding Machine:

Injection Molding Machine Specifications of Clamping Uint

CLAMPING UNIT	To understand the meanings of Injection Molding Machine Specifications
Clamping Unit	The task of the clamping unit of a rubber injection molding machine lies in its safe and powerful holding together of the tool whereby an even transfer of force over the entire area of the clamping plates is guaranteed.
Clamping force	Its dependance on cavity pressure and method to compute cavity pressure. The amount of pressure the machine can exert on the mould, to keep it closed, while mould (tool) is being filled with molten plastic under enormous pressure. Typically tonnage is the defining size of the machine.
Maximum daylight mm and Mold Opening Stroke	Opening Stroke. When the mold is placed on the mounting plates of the injection molding machine, it can be opened easily. The movable side of the mold is moved back from the fixed side with the help of the clamping unit. The distance between the two halves of the mold is called the opening stroke.
Minimum Mold Height	Its relationship with mold open stroke and daylight. Minimum Mold an injection machine can hold or work with. Adjust the moving platen forwarding as close as it can to the fixed platen. And then measure the minimum distance between the fixed platen and move platen of injection molding machine.
Maximum Mold Height	Its relationship with mold open stroke and daylight. Maximum Mold an injection machine can hold or work with. Adjust the moving platen retract as far as it can to the fixed platen. And then measure the maximum distance between the fixed platen and move platen of the injection molding machine.
Maximum Daylight	The maximum daylight has to accommodate the height of moving half of mold, the height of molded part, minimum and enough clearance for removal of molded part and height of fixed half of mold. With Hydraulic clamp machine, Maximum daylight = Minimum mold height + mold open stroke.
Clearance between Tiebars and platen size mm x mm	How it accomodates mould.
Ejector Stroke mm	Its significance for ejection of deep parts.

Injection Moulding Machine specifications for injection Unit

INJECTION UNIT	To understand the meanings of Injection Molding Machine Specifications
Screw L/D Ratio	The ratio calculation is calculated by dividing the flighted length of the screw by its nominal diameter. Although several injection molding machine manufacturers now offer a choice of injection units, most injection screws use a 20:1 L/D ratio
Maximum Injection Speed g/s or cc/s	How it ensures melt to spread throughout when in fluid condition- before it freezes. Its relationship with freezing time. After the required amount of molten plastic is accumulated, the injection process is stared. While molten plastic is flowing in a mold, the machine controls the moving speed of the screw or injection speed. On the other hand, it controls dwell pressure after molten plastic fills out cavities.
Maximum injection pressure Kg/cm2	How it overcomes resistance to flow during filling and; pressure phase on account of flowratio and; viscosity. Injection pressures must be high enough to fill the cavity, forcing material into the furthest reaches. Injection pressures commonly range between 70 and 112 MPa (10–16 kpsi).
Plasticizing Capacity g/s or Kg/hr	How it influences cycle time. The parameter that needs to be studied in a plasticizing unit is the plasticizing capacity. The plasticizing capacity is the volume of injectable molten plastic resin that can be prepared in unit time, and this affects the volume of the molded article that can be prepared.
Shot Capacity	Some injection molding machine manufacturers may marked as Shot Weight, Shot size. The maximum weight of molten resin that an accumulator can push out with one forward stroke of the ram during plastics forming operations.
Maximum metering stroke in mm.	Dependance of quality of melt for consistancy of moulding.
Maximum Injection Power.Kgcm/sec.	How it takes care of difficulty in filling for thiner walled and high flow ratio parts.
