We do accept transfer tooling.  Upon receipt, we will inspect and confirm the suitability of it to be used at our facility.  Some tools require minor modifications to work on our equipment, others require more moderate work to be utilized.  At times it is more economical to start with new tooling as opposed to utilizing existing.  Evaluating existing tooling is handled on a case by case basis and we do our best to save our customers money with tooling expenses as long as the opportunity is mutually beneficial.
