After molding plastic parts some need a little more attention. There are parts that can be ultrasonic welded together. Parts also can be assembled together to make a function assembly. Depending on the application the parts will be used for depends on how many steps it takes to complete the part. The more steps used to complete the part the more the part will cost. Parts that take more than one step to complete are called value added. This means the cost of producing the final parts will cost more money.


 If it is a simple shoot and ship part (no secondary applications) then the part could cost as little as .02 cents to make. Think of a model car kit. When you open the box and take out the pieces they are all attached as one. You have to break these pieces off separately, this is due to no other assembly being done at the molder. A simple product molded and packed in a box then shipped out the door.

  


If the part involves assembly and ultrasonic welding with other added parts, then they could cost as much as $20 to make.
