The comparison of the front and back economic benefit of transformation
Economic and Efficiency Analysis before platen-press transformation：
1, in terms of yield
PP plates：It is 22 minutes the time required to every sheet fabrication, the plank quantity of per tour (8 hour/class) production is about 21
, every panel weight is 8.3kg, i.e. the yield of per tour is：21 × 8.3=174.3kg/ classes.
PA plates：It is 45 minutes the time required to every sheet fabrication, the plank quantity of per tour production is about 10, every plank
Weight is 8.5kg, i.e. the yield of per tour is：10 × 8.5=85.0kg/ classes.
2, cost of labor
PP plates：Yuanping City plate pressing machine operation employee is arranged two, and unit labour cost is 88 yuan/class；Class needed for plank per ton
Number is：1000/174.3=5.74 classes, then cost of labor per ton be：5.74 × 2 × 88=1010.24 yuan/ton.
PA plates：Same per tour only needs two employees, and class's number is needed for plank per ton：1000/85=11.76 class, then per ton
Cost of labor be：11.76 × 2 × 88=2069.76 yuan/ton.
3, in terms of energy consumption
PP plates：Per tour power consumption is about 670 degree, is calculated by 1.03 yuan/degree of peak-trough electricity average unit price, needed for per tour production
The electricity charge are：670 × 1.03=690.1 members, then producing the electricity charge that plank per ton is consumed is：690.1 × 5.74=3961.17
Yuan/ton.
PA plates：Per tour power consumption is roughly the same with production PP plates, so producing the electricity charge that plank per ton is consumed and being：
690.1 × 11.76=8115.58 yuan/ton.
Economic and Efficiency Analysis after platen-press transformation：
1, in terms of yield
PP plates：It is 9.6 minutes the time required to every sheet fabrication, the plank quantity of per tour (8 hour/class) production is about 50
, every panel weight is 8.3kg, i.e. the yield of per tour is：50 × 8.3=415.0kg/ classes.
PA plates：It is 13.5 minutes the time required to every sheet fabrication, the plank quantity of per tour production is about 35, every plate
Material weight is 8.5kg, i.e. the yield of per tour is：35 × 8.5=297.5kg/ classes.
2, cost of labor
PP plates：Improved platen-press operation employee need to be arranged four, and unit labour cost is 88 yuan/class；Plate per ton
Class's number needed for material is：1000/415.0=2.41 classes, then cost of labor per ton be：2.41 × 4 × 88=848.32 yuan/ton.
PA plates：Same per tour needs four employees, and class's number is needed for plank per ton：1000/297.5=3.36 class, then often
Ton cost of labor be：3.36 × 4 × 88=1182.72 yuan/ton.
3, in terms of energy consumption
PP plates：Per tour power consumption is about 600 degree, is calculated by 1.03 yuan/degree of peak-trough electricity average unit price, needed for per tour production
The electricity charge are：600 × 1.03=618.0 members, then producing the electricity charge that plank per ton is consumed is：618.0 × 2.41=1489.38
Yuan/ton.
PA plates：Per tour power consumption is roughly the same with production PP plates, so producing the electricity charge that plank per ton is consumed and being：
618.0 × 3.36=2076.48 yuan/ton.
From the foregoing, it will be observed that every sheet fabrication time reduces by more than half after transformation；PP plate overall output per manshifts improve
138%, PA plate improve 250%；PP plate costs of labor have saved 16%, PA plates and have saved 42.9%；PP plate grid electricity fee cost sections
About 62.4%, PA plates have saved 74.4%.I.e. PP plates production cost by original 4971.41 yuan/ton be down to 2337.70 yuan/
Ton, has saved 2633.71 yuan/ton；PA plates production cost is down to 3259.20 yuan/ton by original 10185.34 yuan/ton, saves
6926.14 yuan/ton.
