Manufacturing Methodology

  1. Insert the pipe in the hole of the die, draw it through to reduce the size and stretch it out.
  2. When drawing it through the hole, insert a plug (core) in the pipe to adjust the inner diameter and thickness for high dimensional accuracy products.
  3. This process is repeated to make thinner and smaller pipes.
