I’m loosing my hair on this insert mold. Designing and insert mold is usually not very difficult. But if the terminals were not punched correctly and and all of the mold fittings supporting that terminal were out of its dimensional tolerances, you’ll get yourself a headache.
Much more difficult when you design the molding die before you even got the final terminal samples’ actual dimensions. Adjusting the drawings can make you lose your hair in 5 days. I can prove that to you.
This is the insert mold that I designed for 1 of our local customers. It took me 3 weeks designing this plus maybe another 1 week for adjusting the terminal fittings.
This is the smallest image I can use so that you can imagine what I am talking about and at the same time respect our customer by hiding the details from you. 
cheers!
