Common questions from international buyers, engineers, architects, contractors and industrial equipment manufacturers.
What does an aluminum extrusion manufacturer do?
An aluminum extrusion manufacturer produces aluminum profiles by forcing heated aluminum billet through a specially designed die. Depending on the project, the manufacturer may also provide tooling, cutting, machining, surface finishing, inspection and packaging.
Can MK Aluminum manufacture custom aluminum profiles?
Yes. Custom aluminum extrusion projects can be developed according to customer drawings, CAD files, samples, dimensions, alloy requirements, tolerances, surface finishes and application requirements.
What information should I provide for an aluminum extrusion quotation?
Ideally, provide the profile drawing or CAD file, aluminum alloy and temper, required length, estimated quantity, surface finish, dimensional tolerances and any machining or fabrication requirements. The more complete the specification, the more accurate the quotation can be.
What aluminum alloys are commonly used for extrusion?
Aluminum extrusion projects commonly use alloys from the 6000 series, including 6063 for applications where extrudability and surface appearance are important and 6061 for applications requiring higher structural strength. The appropriate alloy depends on the final application and engineering requirements.
Can aluminum profiles be used for windows and doors?
Yes. Aluminum extrusions are widely used to manufacture window and door frames, tracks, glazing components, structural sections and architectural systems. Profile geometry, alloy, wall thickness and surface finish should be selected according to the specific building application.
What are aluminum extrusion profiles used for?
Aluminum extrusion profiles are used for industrial automation, machine frames, conveyor systems, workstations, architectural windows and doors, curtain walls, solar mounting systems, equipment frames, structural components and many customized applications.
What surface finishes are available for aluminum profiles?
Common options include mill finish, anodizing and powder coating. The most suitable finish depends on the desired appearance, environmental exposure, corrosion-resistance requirements and application.
How long can aluminum extrusion profiles be supplied?
Standard profile lengths depend on the product and transportation requirements. Custom cutting can also be discussed when a project requires specific finished lengths. Customers should confirm the required length before quotation.
How do I choose an aluminum extrusion supplier?
Buyers should evaluate manufacturing experience, production capability, engineering support, material control, dimensional inspection, finishing quality, communication, packaging and international delivery capability, rather than comparing price alone.
Can I request a sample before mass production?
Sample and prototype arrangements can be discussed for custom aluminum extrusion projects. The exact process depends on the profile design, tooling requirements, quantity and project specifications.
