Bending
Steel dies bend metal to shape materials for your small business or industrial shop. JT&M manufactures durable press dies for any metal forming, including thin metals and metal bars.
Cutting
Steel die sets apply slow, steady pressure for clean cuts. Die sets can be used in leatherworking, jewelry, industrial manufacturing or any application requiring consistent cuts on sheet metal, leather and other materials.
Forming
Press dies form sheet metal, metal rods or plastic using even pressure. JT&M die sets deliver consistent results for any forming application.
Punching
Die sets for a punch press are made of steel to deliver consistent results over the life of your press to punch sheet metal or leather.
Riveting
Setting rivets with an arbor press results in the highest accuracy and repeatable results. Steel die sets are made for a variety of materials, including sheet metal and leather.
Thread Cutting
Thread cutting dies allow manufacturers to cut threads cleanly without long chips clogging the die. Precision die manufacturing by JT&M produces finished threads that are sharper and less likely to deform under use.
