Analysis of the Causes of Shock Pattern in Injection Moulding Products

Analysis of the Causes of Shock Pattern in Injection Moulding Products

The surface of a rigid plastic part such as PS near its gate is densely corrugated centered on the gate, sometimes referred to as a grooving pattern. The reason is that if the melt viscosity is too large and the mold is filled with stagnant flow, the material at the front end will quickly condense and shrink as soon as it comes into contact with the surface of the cavity, while the subsequent melt expands and expands the shrinkage of the cold material to continue the process. Alternately, the surface of the stream has been formed by alternating flow patterns.

Solution:

(1) Increase the temperature of the barrel, especially the nozzle temperature, and increase the mold temperature.

(2) increase the injection pressure and speed, make it quickly fill the mold cavity.

(3) Improve the flow path and gate size to prevent excessive resistance.

(4) The mold must be well vented, and a sufficiently large cold material well should be provided.

(5) Do not design the parts too thin.
