Product introduction
The rod
rods are manufactured from state-of-the-artwork supplies formulated to offer the high performance & sturdiness demanded by our prospects.The core of the rod is manufactured by the pultrusion process. This entails impregnating excessive power continuous glass fiber filaments with a liquefied resin. The fibers are drawn in to a heated die where the resin matrix is cured, bonding the fibers collectively and allowing mechanical loads to be transmitted by way of the matrix and distributed amongst the fibers.The resulting pultruded rod combines both the high stiffness required to push the rod by way of lengthy distances of ducting, with the pliability to handle tight bends without harm. This interior core is then coated with a highly durable, scratch resistant polypropylene sheath which protects the core from mechanical injury. 

The frames
Frames are additionally a characteristic of the Hunter programs. a larger footprint for stability; steel brake handles that can final ceaselessly; twin rod out-feeding positions and wheels contained in the frame width. The 2 smallest sizes function frames with the feedout constructed into the handle. All frames will be laid down on both aspect. These are simply among the design features that will make each unit more usable and friendly for the tip person.
Rod choice Which is the right rod diameter for any given application? The rod choice is normally governed by several elements including:
The size of ducting it’s to be pushed by means of
The gap the rod is to be pushed
The number and tightness of bends in the ducting
If the ducting is already occupied by cable
When being pushed via the duct, any rod will tend to form “sine waves hitting the wall of the duct at certain intervals.
Each time the rod comes in touch with the wall of the duct, it causes friction. The friction will build and eventually forestall the rod from being pushed any further. Small rod in giant duct will make more frequent contact with the ducting; the identical rod in smaller duct will make much less frequent contact and due to this fact much less friction so it may be pushed additional. Giant rod in small ducting is an effective situation, however decreased flexibility of the rod might trigger increased friction in the tighter bends.
