Molded plastic Soft plastic (polyvinyl chloride, polyethylene)
Hard plastic (acrylic, polycarbonate, ABS, etc.)
Other applications Check materials, applications and work.
(Bending, caulking, punching, robotic hand, and scissors.)

Check How big is the "size of the cut portion"?

dimensions Metal Angle (mm mm) [select model by cross-section area]
Round ( mm)
Plastic Angle (mm mm) [select model by cross-section area]
Other applications Check materials, applications and work.

Usage What is the "state/environment of the work"?

Used mounted on automated machinery and robots.
Used for manual work.
Used mounted on a jig. And so forth

Select model Choose a model suitable for the purpose.

Choose based on "usage and cut dimensions" for the main unit, and "material and dimensions/shape" for the blades.
Refer to "product specications" for the main unit/blade characteristics/usage, respectively. Also when
selecting the machine, refer to "capability selection chart".
The shape/material of the workpiece may not be compatible with standard products.
