Pultrusion Dies:
We manufacture and supply various pultrusion dies for rods,
tubes, beams and shapes. Our equipment&tooling factory
has full range of machinery&tooling including precision
machine tool, line-cutting machine, hammering machine, lathe,
planer, grinder, polisher, borer,
special system for gun-grilled die, etc. Combining excellent
equipment, strong R&D team, experienced workers, we always
try to offer quality, fast delivery, competitive price, perfect
service
Exclusive Advantages:
1. Outstanding staff and workers.
2. Competitive Price: Obtainable by our high-efficiency
and reasonable control of the cost.
3. Designing and manufacturing by machinery designers and
process/technique specialists jointly.
4. Special start-up services: Most of our staff have been
studying in pultrusion process for a long time. so we can
offer special help for both those who are in pultrusion for
the first time and those who have experience.
5. Quick action in response to any inquiry, custom design
and manufacture, and delivery.
6. Perfect services: for each order we'll study carefully
in all aspects and try our best to save customer's cost and
give best solution. we do not just sell products, we sell
a way to make profit and solve problems.

Gun dies:
 Gun
die is integrity die, there is no parting lines. We can supply
not only round gun dies, but also oval dies, flat beam
dies, square/rectangular dies, etc.
| Why Gun-drilled Die? |
1.Good surface
finish: No half-line
left on the rods/tubes surface.
2.Easy to clean and set:
It takes only 1/3-1/5 time
to clean and set gun dies.
3.Long life-time:
Avoid damage along parting
line. Generally, service time of gun die is
1.5-2.5 times that of parting die.
4.Avoid pultrusion failure:
Parting die is more likely to cause
pultrusion failure due to die error, un-proper die
setting, accumulating of resin pieces along parting
lines, etc.
5.More precise profiles:
In pultrusion of small rods, errors in die
manufacture and setting may cause large fluctuation
in rod diameters. Gun-dies decrease errors
greatly.

Preforming system:
Besides formulation and heating control, preforming system
is also criticle for successful and constancy pultrusion.
Before entering die, impregnated fiberglass rovings and mats
must be properly arranged and placed. un-proper preforming
system causes failure of pultrusion, bad quality, and other
problems.
Please note, preforming system is far from easy as most people
think of. Firstly, it must be designed based on profile design
to meet the physical requirements. Secondly, it must let all
reforcements running freely and smoothly, to avoid any
breaking of rovings, mats or cloth. Thirdly, for dies with
mandrels, the preforming system is the only device to keep
uniform thickness of pultruded profiles. Im-proper preforming
may cause eccetric and even breaking of pultrusion. Fourthly,
for complex profiles, preforming system is a large challenge.
UNICOMPOSITE design and manufacture successful preforming
system for every die. we always try every new die and its
preforming system out to make sure they are perfect.
