What are the key technical parameters of injection molding machine
1、 Technical parameters of injection molded parts
(1) Screw diameter: the outer diameter of the screw
(2) Effective length of screw: the length of screw thread (mm) is often expressed in L
(3) Screw length diameter ratio L / D: the ratio of effective length to diameter of screw
(4) Screw compression ratio V2 / V1: ratio of screw groove volume V2 in screw feeding section to screw groove volume V1 in metering section
(5) Injection stroke: the moving distance of the screw and the retreating distance of the screw
(6) Theoretical injection volume: the product of the cross-sectional area of the screw head and the injection stroke
(7) Injection volume: weight of PS injected by screw at one time (g)
(8) Injection pressure: pressure of head pre melt during injection, MPa
(9) Injection speed: the speed at which the screw moves during injection (mm / s)
(10) Injection time: the short time for the screw to complete the injection stroke during injection molding
(11) Injection rate: theoretical volume of injection per unit time; Screw Jie area × At speed
(12) Screw speed: the speed range of the screw when the material is plasticized
(13) Plasticizing capacity: the weight of plasticized materials per unit time
(14) Screw torque: the torque driven by the screw when the material is plasticized (n / M)
(15)Nozzle elongation: the length of the nozzle extending out of the front formwork and the mold installation plane
2、 Technical parameters of clamping parts
(1) Clamping force: the locking force to lock the mold in order to overcome the expansion of molten material
(2) Forming area: refers to the projected area of clamping force under certain mold cavity pressure
(3) Mold opening force: the force to take out the product and open the mold
(4) Mold opening stroke: refers to the distance to move the template when taking out the product
(5) Template size: the installation plane size of front and rear fixed molds and moving molds
(6) Volume modulus: the thickness and small thickness of the mold that can be installed on the injection molding machine
(7) Template opening distance: the opening distance between the fixed template and the moving template of the injection molding machine is small
(8) Tie rod spacing: the spacing between the horizontal and vertical inner sides of the tie rod of the injection molding machine (mm)
3、 Overall performance parameters
(1) Motor driving power: power of driving oil pump motor (kw)
(2) Oil tank capacity: rated capacity of oil tank of hydraulic system
(3) Machine volume: the length× high × wide of the shape of the machine
(4) Weight: the total weight of the machine
