What are the key technical parameters of injection molding machines?

An injection molding parts technical parameters

(1) screw diameter: the outer diameter of the screw size

(2) effective length of the screw: the length of the screw with threads (MM) is often expressed in L

(3) screw L/D ratio: the effective length of the screw and the diameter of the ratio

(4) screw compression ratio V2/V1: screw filling section of the first groove volume V2 and metering section of the last groove volume V1 ratio

(5) injection 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 head pre-melt material during injection MPa

(9) Injection speed: the maximum speed of the screw movement during injection (mm/s)

(10) Injection time: the shortest time for the screw to complete the injection stroke during injection

(11) injection rate: the theoretical volume injected per unit of time; screw JIE area × to the maximum speed

(12) screw speed: when the material is plasticized, the minimum and maximum speed range of the screw

(13) plasticizing capacity: in unit time, the maximum weight of plasticized material

(14) screw torque: when the material is plasticized, the maximum torque of the screw drive (N / m)

(15) nozzle elongation: the nozzle extends out of the front template, the length of the mold mounting plate

Second, the technical parameters of the mold-closing components

(1) Clamping force: to overcome the melt expansion mold, the maximum clamping force to lock the mold

(2) Molding area: the maximum projection area of clamping force under a certain cavity pressure

(3) Mold opening force: the maximum force to open the mold to take out the product

(4) Mold opening stroke: the maximum distance the mold plate can be moved to take out the product

(5) Mold plate size: the front and rear fixed mold and dynamic mold plate mold installation flat size

(6) mold capacity: the maximum and minimum thickness of the mold that can be installed on the injection molding machine

(7) Mold plate opening distance: the maximum and minimum distance between the fixed and dynamic mold plates of the injection molding machine

(8) Tie rod spacing: the spacing between the horizontal and vertical inner side of the tie rod of the injection molding machine (mm)

Third, the machine performance parameters

(1) Maximum motor drive power: the power of the motor driving the oil pump (KW)

(2) Oil tank capacity: the rated capacity of the hydraulic system oil tank

(3) Machine volume: the maximum length × height × width of the machine shape

(4) Weight: the total weight of the machine
