As the conclusion of my training is coming closer and closer still, I found out there is actually a process that I neglected to elaborate which is the reason I am going to bring it out now. The process is know as annealing and for those who are versed in material properties and its manufacturing processes should grasp what I am going to explain later. It is only used on futa with edges and in this case there are 2 type which is currently under production, a 2 edge futa and a 3 edge futa. For your information, the sole reason that brought upon annealing is due t the fact that these futa has the tendency to crack after undergoing ultrasonic welding, unable to withstand the force of the downward horn. The working principle behind annealing is that the structure of a material is strengthen when it is heated up and rapidly cooled down to room temperature. Besides that, I also spent a lot of my hours hanging around the assembly machine solely responsible for the production of the 3 edge futa because of a unique problem of its own. As it moved along the conveyor belt, the futa tends to spin and got stuck on one of its edges. Then when an operator comes along move it back into position, there is a possibility that the edge will be dented unintentionally resulting in a NG product. However, since the root of the problem is the nature of the design, there is nothing much one can do about it unless there is a specifically design conveyor belt for it which is uneconomical in terms of flexibility.
