Temperature Control System Design of Rapid Thermal Cycle Injection Moulds with Electric Heating

Abstract:

Rapid thermal cycle injection molding technology with electric heating is a kind of widely-used and high-end injection molding technology; it can raise quality of plastic parts without reducing injection molding production efficiency. In the key technology of rapid thermal cycle injection molding with electric heating, the temperature control is the core technology. In this paper, we mainly design the temperature control system of small and medium size rapid thermal cycle injection molding with electric heating. First, give the temperature control parameters of mold, design the temperature control scheme , select type of PLC and design software of human-computer interface; second, the hardware, software, temperature control algorithm and human-computer interface of temperature control system are designed detailed; last, the temperature control system is simulated.
