Introducing fiber processing methods such as cutting, drilling, and punching! 【Plastic-free】
"Vulcanized fiber" is a natural material made from cotton pulp and wood pulp, suitable for the ecological era. In addition to cutting processes using rotary slitters and saws, it can be processed through punching with a punch press, threading with dies or lathes, and other methods, totaling eight processing techniques. 【Processing Methods】 ■ Cutting processing ■ Punching processing ■ Lathe flat cutting processing ■ Adhesive processing ■ Drilling processing ■ Threading processing ■ Bending processing ■ Drawing processing *For more details, please refer to the PDF document or feel free to contact us.

Detailed information
-
Cutting Process Fiberboard with a thickness of 5mm or less is cut using a metal shear or rotary slitter. For boards thicker than 5mm, a circular saw or band saw is used. Additionally, a jigsaw can also be used in a manner similar to woodworking.
-
Punching processing Fiber boards can be freely punched with a regular punch press. Boards thicker than 3mm can be easily punched if preheated (to around 80°C). Use a die that fits perfectly and align the guide well with the punch.
-
Flat machining on a lathe. The speed and feed for lathe machining are similar to those for brass, and the cutting edge of the tool has a larger rake angle (20° to 30°) to facilitate chip removal. In mass production, using carbide is more economical. Flat machining is similar to brass machining.
-
Subsequent processing After roughening the surface of the fiber with materials like emery cloth and removing the grease, bonding is performed. Adhesives such as melamine and epoxy are preferred, and heating during bonding provides greater adhesive strength and stability compared to room temperature bonding.
-
Drilling process A standard 60° drill is used for drilling. High-speed steel drills are preferable, and a faster drilling speed than metal results in a cleaner finish. Additionally, when the thickness of the fiber is 6mm or more, using a small amount of oil will yield a smoother finish.
-
Thread cutting can be done similarly to metal using a die or lathe. When tapping, the hole should be drilled 0.1 to 0.2 mm larger than for metal, and it is acceptable to use a medium tap or finishing tap from the beginning.
-
Bending processing Since the fiber tries to return to its original shape even when bent in a normal state, if you soak the bending part in water or warm water beforehand and then heat that part while bending it, you can bend it sharply, straight, or purely as desired.
-
Dyeing process Similar to bending processing, moisture is absorbed by the fiber in advance to make it flexible, and then heat and pressure are applied to shape it into a dyeing mold. Depending on the thickness and shape of the material, rough and final dyeing molds may be used for shaping, just like in the case of metals.

Company information
Hokuyou Oriental Fiber produces eco-friendly vulcanized fiber in a rich natural environment at the foot of Mount Fuji. Vulcanized fiber (nicknamed "fiber") is made from natural paper materials (cellulose), which allows it to possess the characteristics of paper while exhibiting far greater strength than paper. It also excels in final disposal, as it can return to the soil within the natural environmental cycle. As a top leader capable of balancing industrial development with next-generation environmental protection, we aim to continue providing the earth-friendly material "vulcanized fiber" to contribute to your daily life.
