Manufacture
The three traditional honeycomb production techniques: expansion, corrugation and moulding were all developed by 1901 for non-sandwich applications. For decorative applications the expanded honeycomb production reached a remarkable degree of automation in the first decade of the 20th century.
Today honeycomb cores are manufactured via the expansion process and the corrugation process from composite materials such as glass-reinforced plastic (also known as fiberglass), carbon fiber reinforced plastic, Nomex aramide paper reinforced plastic, or from a metal (usually aluminum).
Thermoplastic honeycomb cores (usually from polypropylene) are usually made by extrusion processed via a block of extruded profiles or extruded tubes from which the honeycomb sheets are sliced.
Recently a new process to produce thermoplastic honeycombs has been implemented, allowing a continuous in-line production with direct lamination of skin to cost efficient sandwich panel production. Continuous in-line production of metal honeycomb can be done from metal rolls by cutting and bending.
Today, a wide variety of materials can be formed into a honeycomb composite. For example paperboard honeycomb is used in paper pallets and package cushioning, blocking and bracing.

Famous quotes containing the word manufacture:
“Yes, that’s what I needed. Living flesh from humans for my experiments. What difference did it make if a few people had to die? Their flesh taught me how to manufacture arms, legs, faces that are human. I’ll make a crippled world whole again.”
—Robert Tusker, and Michael Curtiz. Wells (Preston Foster)
“The profession of magician, is one of the most perilous and arduous specialisations of the imagination. On the one hand there is the hostility of God and the police to be guarded against; on the other it is as difficult as music, as deep as poetry, as ingenious as stage-craft, as nervous as the manufacture of high explosives, and as delicate as the trade in narcotics.”
—William Bolitho (1890–1930)
“Culture is an instrument wielded by teachers to manufacture teachers, who, in their turn, will manufacture still more teachers.”
—Simone Weil (1909–1943)
