If you’ve determined that the rollers need to be replaced, locate the screws that hold them in place. Use the appropriate screwdriver to remove these screws and take out the damaged rollers. Insert the new rollers in the same position, securing them with screws. Ensure they are appropriately aligned and able to move freely without obstruction.
This stage entails actual extrusion process, which begins immediately after the ram starts exerting pressure on the billet. Extrusion machine features a hydraulic press, which can exert pressure of up to 15,000 tons on the billet and die.
Aluminum is ideal for contemporary windows and doors framing since the material is strong and bears a substantially large amount of weight.

The production of aluminum fences is scalable to huge numbers. An aluminum fence is typically made using a manufacturing process known as extrusion. This procedure entails nothing more than moving blocks of aluminum through a dying system.
If you prefer a more minimalist look, opt for simple cast iron wall art or decorative hooks to add a subtle touch of style to your home. These understated pieces can complement a range of interior design styles, from modern to rustic, and can be easily integrated into existing decor.

8. Regular Maintenance To prevent future issues, conduct regular maintenance on your sliding doors. Clean the tracks and rollers every few months and inspect for any signs of wear or damage.
Surface finish: This dramatically impacts the performance of doors and windows. If the surface finish is not good, the corrosion resistance, wear resistance, oxidation resistance and other properties of doors and windows may be reduced.
Size: There are two types of door and window profile sizes, one is standard size and the other is customized size. We can make custom sizes according to your project needs.
Quality standards: There are different quality standards for door and window profiles. According to your local requirements, you can refer to the standards of profiles and provide requirements to the manufacturer. Or you can take the profile's weight, appearance, hardness, strength, and oxide film.
thickness as a reference direction and coordinate with the aluminum material manufacturer.
Thickness: This is one of the important indicators of doors and windows, which is directly related to the safety performance of doors and windows. The wall thickness of the main stress-bearing rods of aluminum alloy doors and windows should be more than 1.4 mm. The wall thickness of the main stress-bearing rods of aluminum alloy doors should be more than 2.0 mm. The tensile strength should reach 157N/mm.
Type: There are many types of profiles now which can fully meet the needs of any project. Generally, different use environments will have specific profiles to choose from.
For example:
Standard aluminum door and window profiles
Thermally broken aluminum door and window profiles
Sliding aluminum windows and doors profiles
Casement aluminum windows and doors profiles
Folding aluminum windows and doors profiles
Soundproof aluminum alloy profile
Generally, the profile configuration should be selected according to the project requirements when choosing aluminum materials for doors and windows. If you have special requirements, you can communicate with the aluminum profile manufacturer. Now the technology from extrusion to processing door and window profiles is very mature. As a professional aluminum factory, we have produced aluminum for any project. We are fully confident in producing aluminum for any project.
With this in mind, manufacturers have ingeniously come up with numerous ways to create aluminum profiles. Their uses range from simple door kick plates and window frames to far more complex, larger-scale applications such as shipping containers and piping channels. Continue reading to learn more.



Selling old wrought iron fences to artists or crafters can be a fulfilling way to give new life to what might otherwise be discarded. Artists and crafters often look for unique materials that can be transformed into art pieces or functional items.
Despite their many advantages, aluminum window extrusion profiles do have some drawbacks. One of the main concerns with aluminum windows is their poor thermal performance. Aluminum is a highly conductive material, meaning that it can easily transfer heat and cold into and out of the home. This can lead to increased energy costs as the home's heating and cooling systems work harder to maintain a comfortable temperature.
How do you tell the difference between wrought and ornamental iron? Here are the main differences:
