What are the key technical parameters of injection molding machines?
- Aug 31, 2018 -

1. Technical parameters of injection parts

(1) screw diameter: outer diameter of screw

(2) effective length of screw: the length of thread on screw (MM) is often expressed in L.

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

(4) Screw compression ratio V2/V1: ratio of the first groove volume V2 of the screw feeding section to the last groove volume V1 of the metering section

(5) injection stroke: maximum distance of screw movement, maximum distance of screw back.

(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 once per screw (g).

(8) injection pressure: the maximum pressure of the head premelted during injection is MPa

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

(10) injection time: when injection, the shortest time for the screw to finish the injection stroke.

(11) injection rate: theoretical volume injected in unit time; screw JIE area * at maximum speed.

(12) screw speed: the minimum maximum speed range of screw when plasticized.

(13) plasticizing capacity: maximum weight of plasticized material within unit time.

(14) screw torque: the maximum torque (N/m) driven by screw during plasticizing.

(15) nozzle elongation: the length of the front mold and the length of the mold installation plane.

Two. Technical parameters of mold closing parts

(1) clamping force: in order to overcome the maximum locking force of the mold, the mold is locked to avoid the expansion.

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

(3) mold opening force: the maximum force for the mold to be opened for taking out the product.

(4) opening stroke: to remove the product and maximize the movement of the template.

(5) template size: the front and back fixed die and the movable template mold are installed flat size.

(6) modulus of accommodation: maximum thickness and minimum thickness of mold installed on injection molding machine.

(7) template opening distance: the maximum and minimum distance between the fixed and the movable formwork of the injection molding machine.

(8) pull rod spacing: the distance between the horizontal and vertical directions of the drawbar of the injection molding machine (mm)

Three, the whole machine performance parameters

(1) maximum driving power of motor: power of driving oil pump motor (KW)

(2) tank capacity: rated capacity of hydraulic system tank.

(3) machine volume: the maximum length, width and width of a machine.

(4) weight: the total weight of the machine.
