Once your part is extruded and machined, VMT applies the finish your drawing calls for. Below is the surface treatment process we most commonly perform, custom aluminum extrusion anodizing, along with the other finishing options available.
Extrusion is the process of forcing semi-molten aluminum through a forming tool or die using hydraulic pressure. Dies are made from hardened tool steel and the complexity of the possible profiles can range from simple box sections to sophisticated automobile frame members or electrical heat sinks.
After extrusion, finished part lengths are cut off in sections and can be further processed with drilling, tapping, anodizing, and more. Extrusions are found in construction, architecture, industrial, automotive, transportation and electronics applications, among many others.
Extrusions offer several distinct advantages for product developers:
Are you looking for high-quality aluminum extrusion and CNC precision machining services? We provide aluminum extrusion and CNC machining services and have obtained ISO 9001 and IATF 16949 certification.
We use advanced technology to ensure that aluminum parts are dimensional accurate and structurally strong. Aluminum profiles of various shapes and sizes can be customized according to customer needs, including round, square bars and tubes. Choosing us means choosing reliable quality and service.
We have a 5,000-square-foot factory with 100 CNC machines, several dedicated work cells, and deburring and punching systems. These equipment focus on CNC machining and are dedicated to the manufacture and assembly of aluminum extrusions, ensuring the efficiency and quality of the production process.
We provide a quote overview within 2 hours of receiving the request and submit a manufacturing feasibility plan within 4 hours, which will contain practical suggestions and solutions to support your project decision and production arrangement.
VMT has passed ISO 9001:2015, IATF 16949, SGS On-site audit and 11 patents. Provide Thickness, Roughness, RoHS, and Material certification.There are 12 quality control points and 8 quality inspection procedures in the production process to ensure that the product qualification rate reaches more than 99.8%.
VMT specializes in providing customized extrusion + CNC machining services for multiple industries, covering a wide range of fields such as electronics, consumer products, aerospace and automotive. We select different grades of aluminum alloy materials according to the specific needs of each industry, which have excellent strength, corrosion resistance and formability.
During project execution, our design and programming team will carefully evaluate the cost, manufacturability and complexity of each project to ensure that the proposed solution not only meets customer requirements, but also optimizes budget, time and material usage. We are committed to providing customers with efficient, accurate and cost-effective machining services.
We follow the standard general NADCA tolerances. However, if your requirements are very precise, then the precision tolerances standard can be followed once we have confirmed your designs.
A standard profile is a stock shape a supplier already keeps in inventory. The cross section is fixed, and the buyer selects from what is already available rather than defining the shape themselves. Custom aluminum extrusions start from a customer drawing instead, with a die built specifically for the required cross section.
Because the die is built to the drawing, VMT can also add the cutting, drilling, tapping, or milling features called out in the drawing. This is what separates custom aluminum extrusion profiles from something pulled off a shelf, the part is built around the customer's specification from the start, not adapted after the fact.
Yes. VMT reviews the drawing first to confirm the cross section is feasible to extrude, then builds a die matched to that geometry rather than modifying an existing one. This is standard practice for custom fabricated aluminum extrusions, the die is the starting point, not a constraint the design has to fit around.
Once the profile is extruded, it moves into CNC machining for the features the drawing specifies, holes, slots, threads, or finished end faces. VMT handles both stages in house, so the part does not get handed off to a separate shop between extrusion and machining.
The right choice depends on what the part needs to do. A structural bracket, a heat sink, and an enclosure each put different demands on strength, weight, corrosion resistance, and how easily the alloy machines and takes a surface finish. VMT works across a range of custom aluminum alloy extrusions so the grade can be matched to the application rather than the application being forced to fit one grade.
For general purpose structural parts, custom 6061 aluminum extrusions are a common starting point, offering a balance of strength and machinability. 6063 is often chosen instead when surface finish and anodizing appearance matter more than peak strength.
Where higher strength is the priority, such as aerospace adjacent or high load applications, custom 7075 aluminum extrusions are typically considered. Send the drawing along with the load, environment, and finish requirements, and VMT will confirm the grade before quoting.
Minimum order quantity is tied to die size rather than being a fixed number across every project. Smaller extrusion machines run on a minimum of 0.5 ton of aluminum, while larger machines require a minimum of 1.0 ton of 6063 aluminum. Die size and part complexity are also two of the main factors behind custom aluminum extrusion cost, so a simpler profile on a smaller press will generally have a lower minimum than a large or complex one.
Tooling lead time depends on die size and complexity rather than being fixed across all projects. Small dies typically take about 2 weeks, while larger or more intricate dies take closer to 4 weeks. This covers the tooling stage only, the schedule for CNC machining aluminum extrusions afterward is confirmed separately once the profile itself is ready.
Catching a die design issue at this stage, before the tooling is cut, avoids rework that would otherwise extend the project timeline once production starts.
VMT follows standard NADCA tolerances as the baseline for extrusion work. Once the drawing and application requirements are confirmed, tighter precision tolerances can be held where the design calls for it, rather than applying the same standard tolerance to every feature regardless of function.
This is part of operating as an aluminum extrusion CNC supplier that machines in house rather than outsourcing the secondary operations, tolerance on a drilled hole or a machined face can be controlled directly instead of depending on a separate vendor's process.
