How to polish aluminum extrusion profile?  All you need is aluminum profile, aluminum profile polishing machine, and the polishing wax!


The basic is aluminum extrusion profile, it is easy to get them in the extrusion factory and it is mill finished profile and it should be aged in the furnace to get the hardness.  If the finished polishing aluminum profile quality request is very high level and you had better pay more attention to the billet chemical composition and extrusion moulds, otherwise, it is difficult to remove the deeper die line and heavy scratch and it will be harmful to the finished product rate.

Aluminum profile polishing machine is main role and now it get into act. 
Aluminum profile polishing machine is one kind of special machine for the surface treatment of aluminum profiles. There are always die line, scratch, marks on the surface of aluminum extrusion profiles after the extrusion in the aluminum extrusion factory, which affects the surface quality and market competition of aluminum profiles. Aluminum extrusion profile polishing machine can solve this problem effectively. The surface of aluminum profiles will be as the mirror after the mechanical polishing.

Aluminum extrusion profile polishing machine function
Aluminum polishing machine for mechanical polishing is to remove the die line, extruded line and other defects on aluminum extrusion profile surface.

Aluminium profile polishing machine working principle
The worktable drives aluminum profile to have reciprocating linear running; make the aluminum profile polished through the rotation of the motor drives the polishing wheel; polishing wax or agent is used on the surface of the cloth or flax wheel as a polishing media.

Aluminum extrusion profile polishing machine future

Such as three (two) acid aluminum polished profile, electrolytic polished profile, polished and oxidized bright profile, polished and electrophoresis profile as well as polished and nickel plated profile, All require mechanical polishing treatment on the surface for the purpose of removing such surface defects as naturally oxidized film, extruded lines etc. to get a bright mirror effect on the surface of aluminum profile.

what is the difference between strip feeding and injection thermal break aluminum profile?

What is the difference between strip feeding and injection thermal break aluminium profile

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.
