Metex copper
gauze is a proven, economical way to clean plastic extrusion
equipment and molds—in a fraction of the time required
by household cleaning products—while the machinery is still
hot. Metex copper gauze helps dramatically reduce downtime—with
as much as 120 hours of additional machine output achieved with
a typical low-compression, single-screw, 2 1/2" extruder.
This
versatile cleaning material has been used by many leading plastic
converters to clean extruders, dies, screws, and similar
machinery. It is especially economical where product purity
requires frequent maintenance—for example, when molding
material or color must be changed often, or thin films coated.
Among the many proven applications for Metex copper gauze are removal
of “drool” on sheeting extruders or tubing dies, cleaning vent holes in dies and
injection molds as well as extrusion screws and barrels. Copper gauze is:
- Safe
Soft copper will never scratch or damage costly machine parts. No metal splinters make it
safe for workmen, too.
- Rust-Free
Pure, solid copper will not rust or contaminate end product.
- Tough
Interlocked loops of heavy gauge copper wire make it impervious to disintegration.
- Effective
Knitted structure keeps flat wire on edge for excellent scraping action without scratching.
- Non-Flammable
Because Metex knitted copper gauze is 100% metal, it can’t burn or even smoke when used
directly on hot equipment.
- Low Cost
Costs less than currently used household-type metallic cleaners.
- Efficient
Compared to other methods (charring, wire brushes, metal sponges), Metex knitted copper
gauze cleans in less time—often less than one hour to clean a machine.
- Two Grades in One
You get two grades of cleaning power in one grade of Metex knitted copper gauze. Use as
supplied for normal cleaning, or turn insideout for heavy cleaning.
Cleans Without Scratching or Damaging Critical Working
Surfaces—While Costing Less than Other Cleaning Products
Metex copper gauze is knitted from flattened copper wire into a seamless, continuous,
flat stocking—giving it excellent scraping properties—while its softness eliminates the
danger of scratching or galling hard-metal surfaces. (Small amounts of industrial-grade
silicone grease as a release aid will enhance its cleaning properties.) Metex copper gauze
is also economical. In fact, when purchased in 400-foot rolls, Metex copper gauze may
actually cost less than common conventional cleaning materials. Most important are the
savings in eliminating equipment downtime. In fact, simply feeding a length of copper
gauze through the hopper and into the barrel of a single-stage extruder is often all that
is required to adequately clean this equipment without cooldown. Metex knitted copper gauze is
not only efficient and economical in cleaning screws and barrels on plastic extruders, but
extrusion dies as well as injectionmolding machines.
