How Do You Manufacture Aluminum Profiles For Windows and Doors?

Notably, extrusion is the primary technique used for making these designs of aluminum profiles.

It is quite a detailed process, which starts with designing every profile.

The designing process involves documenting specific functions of the profiles, shapes, dimensions, and material specifications.

Machinability, finishing, and durability are also other crucial aspects considered during design process.

After completing the designing process using computer software, steel die for producing the design is also produced.

It involves using a hydraulic press to push the billet through the die to create the desired window or door aluminum profile.

The actual extrusion process involves the following details;

Extrusion Billets

A typical extrusion billet comes in form of a solid or hollow cylindrical shape.

In most instances, the billets are cast in an electric arc furnace with aluminum scraps. They are cut into ideal sizes to match the required profile length.

Preheating Billet

Preheating of the billet and extrusion die takes place before the actual extrusion process starts. The essence is to soften the billet to allow it to be forced through the die?

While at it, you should be careful not to overheat it to a melting point, often about 1200° F. An ideal heating point should be approximately 900° F.

Direct Extrusion

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.

Ideally, the more the pressure, the greater the extrusion it can produce. The machine applies the initial pressure crushing the billet against the die.

This die becomes shorter and wider until it can never expand anymore due to container wall restriction. That’s when the aluminum material starts forcing its way out through the die’s orifice and form a particular profile.

Length of an extruded profile is dependent on billet and die opening sizes. There is a runout conveyor, which supports the formed extrusion profile as it comes out of the extrusion press.

Extruded profile may be passed into a cooling bath as it comes out depending on the type of alloy. Cooling is a critical step since it retains adequate metallurgical properties in the metal.

After cooling, you can use the stretcher to stretch these profiles and straighten any twisted part.

Surface Treatment

These profiles are taken through a special surface treatment module to attain the ideal surface finishing. It varies based on user preference and actual setting of the windows and doors.

Cutting

After special finishing operations, you may cut the profiles into shorter lengths depending on the actual dimensions of the windows and doors. While at it, you may use special devices to clamp the profiles, cut and transfer them to a conveyor.

Aging

This process helps to strengthen the aluminum profiles for windows and doors. You can attain natural aging by exposing the profiles to room temperature.

Alternatively, you can go for artificial aging in an oven. Essentially, the aging process design is to ensure there is uniform precipitation of fine particles through the metal.

However, this technique requires sliding its entire length. As such, it may be unsuitable to use in somewhat confined spaces.

Normally, it is a perfect choice for sliding window aluminum frame.

Corner Cleat

It is the ideal method for connecting two identical extrusion profiles at a particular angle. The profile has a channel allowing the cleat often made of another aluminum profile or sheet steel.

This cleat may have a few barbs on each side, cutting into the aluminum to create a friction fit. Alternatively, you can add screws to fix the cleat in position.

Nut Track

This method features a channel designed to fit a nut or bolt head firmly between the flats.

The essence is to prevent nut or bolt head from spinning. You can use multiple fasteners in a single track and position freely.

Hinge

It is the ideal method to fix aluminum profiles while allowing movement. You can attain this in many ways by using two cylindrical features.

Do You Have MOQ When Purchasing Aluminum Profiles For Windows And Doors?

Yes, generally MOQ is often determined by several prevailing factors.

For customized aluminum profiles, we tag a relatively low MOQ since these require a somewhat detailed and intensive approach.

Thus, we offer low MOQ on our products enough to cover the overhead costs.

Moreover, custom designs require thorough quality checks, which eventually adds to the overall production cost.

Nevertheless, we are flexible regarding MOQ, and we can always negotiate and agree based on specific parameters.

First, if you choose custom aluminum profiles for windows and doors, there is a high likelihood they’ll take longer than standard designs.

Secondly, the number of pending orders also determines the specific lead time for manufacturing these components.

In many instances, the manufacturers often fulfill orders on a first-come-first-served basis.

Thus, the more the orders, the longer the lead time.

And importantly, the company policy also influences the actual lead time for making these components.

Some manufacturers adhere strictly to their lead time policies, whereas others tend to be relatively flexible depending on prevailing factors.

Nevertheless, our average lead time is about 15-20 days once you confirm the sample and place the order.
