Artificial Intelligence Mold Temperature Controller
(Fuzzy Logic Controller System)

This system directly and precisely controls the temperature of the mold by applying the fuzzy logic theory in response to environmental changes of the mold. The logic controller is an artificial intelligence system that maintains mold temperature within ±0.5°C from preset values. Its build-in a perfect turbulence flow generator (Reynold’s number 8,500 or higher) can cool down resin in the mold very quickly, shorten production cycle time, and save energy and extend equipments’ life span.

Features

1. High-speed production (Reduce production cycle time)

a)      Enhanced operating ratio by instantaneous preheating.

(Approximately 10-minute to raise 60°C)

b)      Reduce resin cooling time by controlling water directly to the mold and automatically controlling temperature.

c)      Partial temperature control makes it possible to produce sophisticated products;

fast cooling/heating reduces product cycle time.

d)      Can manage top and bottom part temperatures separately so it can produce high quality products.

2. More precise temperature control

a)      Actual mold temperature controlled by sensors inside the mold, on movable and fixed parts in the mold.

b)      It is possible to get defect-free products from the first injection after restarting the machine due to rapid temperature recovery.

c)      It is unnecessary to readjust the molding condition of the machine since constant mold temperature is maintained.

d)      No matter what surrounding temperatures are and the scale gathered, the flow of cooling water is automatically controlled; therefore keeping mold temperature within ±0.5°C.

e)      Direct measurement of mold temperature enables easy diagnosis of troubles of mold, materials, injection molding machines, and others.

3. It is necessary to maintain consistent injection pressure to reduce raw material usage (Reduction rate 8 – 12 %).

4. Save electrical energy and extends system’s life

a) It saves more than 90% of energy by running the heater and the pump during initial preheating stage only, and operating the solenoid valve during production.

b) With much reduced operating of electrical devices and parts, malfunctions occur less often and life span improves.

c) Since constant mold temperature is maintained, the injection molding machine is also managed under good condition, enhancing its own life span.

5. Uniform quality products are possible because it can maintain mold’s consistent temperature.

6. Short cycle time and low defect rate, reduced raw materials usage and electricity consumption. Therefore it is possible to recover capital investment in one or two months.
