1. Technical parameters of injection molded parts
(1) Screw diameter: the outer diameter of the screw
(2) Effective length of the screw: The length of the thread on the screw (MM) is often expressed as L
(3) Screw length-to-diameter ratio L/D: the ratio of screw effective length to diameter
(4) Screw compression ratio V2/V1: the ratio of the volume V2 of the first screw groove in the screw feeding section to the volume V1 of the last screw groove in the metering section
(5) Injection molding stroke: the maximum distance the screw moves, the maximum distance the screw retreats
(6) Theoretical injection volume: the product of the JIE area of the screw head and the maximum injection stroke
(7) Injection volume: the maximum weight of PS injected by the screw at one time (g)
(8) Injection pressure: the maximum pressure of the pre-melted material on the head during injection MPa
(9) Injection speed: the maximum speed of screw movement during injection (mm/s)
(10) Injection time: During injection molding, the shortest time for the screw to complete the injection stroke
(11 Injection rate: theoretical volume injected per unit time; screw JIE area × at maximum speed
(12) Screw speed: when the material is plasticized, the lowest and highest speed range of the screw
(13) Plasticizing capacity: the maximum weight of plasticizable materials per unit time
(14) Screw torque: the maximum torque of the screw drive when the material is plasticized (N/m)
(15) Nozzle extension: the length of the nozzle extending out of the front template and the mold installation plane
2. Technical parameters of mold closing parts
(1) Mold clamping force: The maximum locking force to lock the mold to overcome the expansion of the molten material.
(2) Molding area: refers to the maximum projected area of the clamping force under a certain mold cavity pressure.
(3) Mold opening force: The maximum force required to open the mold to remove the product
(4) Mold opening stroke: the maximum distance the template can move to take out the product
(5) Formwork size: Flat dimensions for front and rear fixed and movable formwork mold installation
(6) Modulus capacity: the maximum and minimum thickness of the mold that can be installed on the injection molding machine
(7) Plate opening distance: the maximum and minimum distance between the fixed platen plate and the movable platen plate of the injection molding machine
(8) Tie rod spacing: The distance between the horizontal and vertical inner sides of the injection molding machine tie rods (mm)
