What are the functions and working case requirements of pouring runner?
Functions and roles of gating system, mainly from the nozzle injection liquid. Use the shortest possible time, faster velocity, smooth transmission, full of everywhere in the cavity, at the same time slots to cavity with molten material equilibrium pressure parts, to ensure the smooth plastic products
To shape.
The working conditions of the pouring channel are as follows.
The discharge distance of each channel in the pouring system should be shortened as far as possible.
The circulating channel is unobstructed, which has little resistance to the flux flow and less temperature loss.
Torque is favorable to the discharge of air in the cavity.
Residue marks at the gate do not affect the appearance of the product.
Rinsing blocks at the front of the melt do not enter the human cavity to avoid affecting product quality
Each port must have certain taper (generally for 2 ° ~ 4 °), with convenient products will handle when stripping away.
