- Die cutting (copying cutting)type: high-end version of Die cutting type, which can be cut with lace or straight edges. Which also will save materials, low failure rate, and not be easy to stick with the cutter.
Long Pitch≥350mm: the front section has reached the cutter before pressing, which is easy to deform.
Short Pitch≤:160mm, the distance between the step form device and the cutter is too small, and the two sides are easy to become warped and bent like a boat.
Press depth: The Press depth of the roof tile machine is between 10 mm and 25 mm.
For a 10mm shallow depth, which will save material, the stereoscopic impression is not strong, and the strength is not high.
