Temp. deviation
|
3 ~ 28℃
|
0.1 ~ 0.5℃
|
Remarks
1) The above-mentioned deviation of temperature comes from difference between medium temperature and that of actual mold.
2) The results came from the comparative test with foreign companies that work in the local market here,
for example, "CONAIR" of U.S.A., "MASTUI" of JAPAN, "REGLOPLAS" of SWITZERLAND and "PIOVAN" of ITALY, etc.

Remark
1) Subject to change depending on working environment.
2) The resins of PP, PS and ABS, etc., are possible to recycle through crushing inferior prototypes. But the other resins are impossible because of the quality problem.
3) The inferior products of PC and ACRYL resins, etc., should be wasted due to the problems of strength.
--Value added advantage of AUTO MASTER (Based on 450ton)--

Productivity

1,451,810 won/12 hrs×24 days = 34,843,440 won/month (418,121,280 won/year)
2,903,620 won/24 hrs×24 days = 9,686,880 won/month (836,242,560 won/year)

Electric consumption without AUTO MASTER
(compared with AUTO MASTER)
|
Motor: 55 kw/hr Heater: 30 kw/hr (Operation rate 50% = 15 kw/hr)
[In working of 12hrs] 70 kw/hr×12 hrs×24 days/month×52 won/kw = 1,048,432 won/month×91% = 954,073 won/month = 11,448,876 won/year
[In working of 24hrs] 70 kw/hr×24 hrs×24 days/month×52 won/kw = 2,096,640 won/month×91% = 1,908,146 won/month = 22,897,752 won/year
|
Note: The heavy operation because of the cycle time delay and largely inferior rate.
3. The saving of injection molding machine.
The plastic products will be produced in time just by more reinvestment
because of the heavy operation of injection molding machine in the conventional method
112,000,000 won/unit
10 years (Machinery depreciation) = 11,120,000 won/year
4. The prolonged life of molds and injection molding machine
1) The injection molding operation with AUTO MASTER can prolong the service life of injection molding machine,
maintain the precise control and guarantee the quality products thanks to being controlled by standardized injection molding process.
- 112,000,000 won×30%×1/10 (Machinery depreciation of 10 years) = 3,360,000 won/year
2) The standardization of injection molding operation with AUTO MASTER can greatly prolong the service life of metal molds up to 50%
and maintain the precise control thanks to removing the overload.
- 15,000,000 won×50%×1/2 (mold depreciation of 2years) = 3,750,000 won/year
