Abstract

This paper is concerned with the practical application of the adaptive model following control (AMFC) theory on the cavity pressure control of the mold filling process in an injection molding machine. The experimental results indicate that the AMFC technique based on the modified Popov‐Landau method is very useful for the cavity pressure control. Two kinds of control algorithms are implemented on a 16 bit microcomputer to control the cavity pressure. The results also show that the AMFC algorithm is superior to the classical PI control in this system when the acrylonitrile‐butadiene‐stryrene (ABS) is injected into a test specimen mold which is designed according to the ASTM code.

## Abstract The numerical simulation of mass and heat transfer model for the curing stage of the resin transfer molding (RTM) process is known as a useful method to analyze the process before the mold is actually built.

This paper is concerned with the practical application of closed-loop control on the gas pressure during the gas-assisted injection molding process. In principle, the gas-injection process can be treated as a valve-controlled tank charging. One of the critical factors for the successful application
