3. Process improvement
Technological advances have been implemented in industrial settings to improve process control and the quality of injection-molded parts:
controlling foam expansion to achieve the highest possible expansion ratio without compromising the final properties of the product. To this end, a process involving the opening of the mold at the end of the filling cycle (core-back) has been introduced.
improving the surface finish of parts produced by pressurizing the cavity before filling.
3.1 Opening the mold (core-back)
The polymer is injected into a shallow cavity (Figure 10 , step...
