Strip feeding thermal break
aluminium profile and injection thermal break aluminium profile difference
Strip feeding thermal break aluminium profile
assembly machine from Brightstar Aluminum
Machinery, your wise and reasonable choice.
Injection process heat insulation technology is
originated from the United States, whose main function is injecting the mixture
that is similar sealing wax into the aluminium extrusion of window and door for
the heating insulation.
Strip feeding process is make two parts of inside
aluminium extrusion profile and outside aluminium extrusion profile fit
together, so that prevent heat conduction to achiever energy saving purpose.
Injection process and strip feeding process of
aluminium profile are featured with light weight, high strength, good rigidity,
sealed waterproof and sound insulation, long using life etc, can significantly
reduce the heat exchange, have a good insulation performance and get energy
saving insulation and good environmental protection effects, which is the
development trend of energy saving and green building aluminium extrusion
profiles.
Here are some differences between injection thermal
break aluminium profile and strip feeding thermal break aluminium profiles.
1. Injection process and strip feeding process
comparison
Injection process means making
the surface finished aluminium extrusion profile linear movement by running
gear. When the heat insulating groove of aluminium profile passed by lower of
the injection machine head, the liquid insulating materials will flow into heat
insulating grooves, after some times solidification, then cut the bridge.
Strip feeding process
Strip feeding thermal break
aluminium profile in general has teeth forming, strip feeding and rolling three
processes.
The teeth forming: to knurl the
notch of aluminum extrusion profile by hard rolling gear, making teeth in both
aluminum profiles
Strip feeding: feed strip into
aluminium profiles, make the outside and inside aluminium profiles fit together
for the following rolling process. One set of strip feeder is ok
Rolling: Have guide and
pre-clamping, clamping and strengthening (vertical and horizontal directions)
processes, rolling forming machine make the aluminum profiles with thermal
barrier rolled, having the compound function. The rolling is the key factor
whether the products is up to standard, setting high pressure alarm and low
pressure alarm.
2 Different heat insulating materials
Injection process’s heat
insulating material is based on polyurethane insulating glue. For the
composition, in general, it is made up of resin component and isocyanate. It is
classified for domestic and foreign categories. The representative
foreign injection material is US Azon, the material is from US or Korea.
The typical domestic injection material is Dali.
Strip feeding process’s heat
insulating material is insulating barrier. Now the standard heat
insulating strip is polyamide66 (commonly known as NYLON66). In order to get
surface appearance and precision, it is common feature for foreign insulating
strip that is produced with PA66 nylon and fine glass fiber. Since the
super fine glass fiber is used in the production, so the tensile strength is
only 60N/mm and the price is very expensive.
3. Production equipment
Injection process is one
technology that machine and insulating glue are inextricable, so that equipment
supplier and insulating glue supplier is the same. The typical imported
equipment is US Azon, the equipment cost is more expensive. For the
domestic-made equipment, make the major changes based on the same function and
the cost is more competitive in the market.
Strip feeding equipment can be
imported equipment and domestic-made equipment, the imported equipment are from
Germany or Switzerland, the domestic-made machine can be offered many
manufacturers and there are many choices for the customers. The whole
machine includes teeth forming machine, strip feeder, rolling machine and
tester.
4 Thermal barrier aluminum extrusion profiles
Injection process thermal break
aluminium profile, as it is extruded one time, minimum the process defects, inject
polyurethane into insulation groove of aluminium profiles once, cured to form a
polyurethane insulating bridge. As polyurethane high adhesiveness, the thermal
bridge and aluminium profiles will be completely whole, so aluminum profile can
get high strength.
Strip feeding thermal break
aluminium profile, two pieces aluminium extrusion profiles, feed the insulating
strip into the groove of aluminium profiles, then rolling process. The profile
need to be knurling, strip feeding and rolling and testing. After that, the
whole process is completed and the strip feeding thermal break aluminum profile
is widely used in window and door, curtain wall project.
5 Thermal break aluminum profile cost
As aluminum profile price is the
same, PVC insulation strip and PA66 insulation strip are different price, the
injection polyurethane glue is different too.
So Injection process thermal
break aluminum profile and strip feeding thermal break aluminum profile cost
will be a little bit different and we can analyses the cost based on the
specific profiles.
