Dear teacher,
Please correct and suggest the better ones.

1)Because of some wrongs on line, so I couldn’t send this email to you earlier.
2)About 2:00 P.M on Tuesday 21 Sept, we downloaded one lot (of goods) of AP 8 with the amount of 9600 pcs according to the invoice.
3)According to the production plan, the workers in the second line should have to produce this goods in this morning, but the machines didn’t work. (break-down)
4)At 3:00 P.M yesterday, we started to producte this goods as soon as the machine was repaired. But this machine has been broken-down again since last night.
5)We need some time to buy and replace accessories. While waiting for it, the workers in No.2 line are still continuing to work at the other machines, before the brokendown machine. (That is a prodution line)
6)We finished P12. There are three of machines running P10.
For a material, we only have P10.

Thanks a lot

1)Because of some wrongs on line, so I couldn’t send this email to you earlier. (Suggestion: Something was wrong on line, so I couldn't send this email to you earlier. Because of some problem on line, I couldn't send this email to you earlier).
2)About 2:00 P.M on Tuesday 21 Sept, we downloaded one lot (of goods) of AP 8 with the amount of 9600 pcs according to the invoice. (Download means to transfer data from one computer to another. If AP 8 is a type of goods, you could use the verb "unloaded." Suggestion: About 2:00 PM Tuesday, 21 September, we unloaded one lot of AP 8, invoiced as 9600 pcs).
3)According to the production plan, the workers in the second line should have to produce this goods in this morning, but the machines didn’t work. (break-down) (If this is past tense (the machines didn't work this morning), rephrase as: According to the production plan, the workers in the second line should have produced these goods this morning, but the machines broke down).
4)At 3:00 P.M yesterday, we started to producte this goods as soon as the machine was repaired. But this machine has been broken-down again since last night. (Suggestion: At 3:00 PM yesterday, when the machine was repaired, we started to produce these goods. But the machine broke down again last night and /has not been repaired yet/has remained broken down since then).
5)We need some time to buy and replace accessories (Suggestion: repair parts). While waiting for them, the workers in No.2 line are still continuing to work at the other machines, (before the brokendown machine.--- I don't understand this part). (That is a prodution line)
6)We finished P12. There are three <strike>of</strike> machines running P10.
For a material, we only have P10. (I am not sure what you mean by "for a material").
