At the beginning, I really don’t know what good advice for my sister, because of his small factories have started operations, but I always feel is not quite right, seemingly saw all the normal procedure, but I always do not trust, so I put my sister to the office to ask they bought him some information, my sister told me that this is the part which they now produce particularly anxious, so the workers are working overtime, after listening to my sister said to let him go to buy the linear actuator machine back, so that workers do not work overtime, but also to advance the customer satisfied product, after my sister listened to me quickly sent to buy linear actuator.
