V-Slot Aluminium Extrusion Profiles

V-Slot and T-Slot aluminium extrusions are both versatile modular framing systems widely used in industries like automation, 3D printing, robotics, and CNC machines. While they look similar, there are key differences in their design, applications, and functionality.

1. Groove Design

• V-Slot:
  V-Slot features a V-shaped groove in the inner corners of the slot. The unique V-groove allows linear motion bearings or wheels to glide smoothly along the profile, enabling both structural support and guided motion in one system.

• T-Slot:
  T-Slot has a T-shaped groove, designed primarily for fastening and assembly. T-Nuts and bolts slide into the groove to attach brackets, panels, or other accessories, but it is not intended for linear motion systems.

2. Functionality

• V-Slot:
  V-Slot profiles are designed for linear motion applications. The V-groove works as a built-in rail system, eliminating the need for additional guide rails. This makes it ideal for applications like 3D printers, laser cutters, and CNC machines where smooth, precise movement is required.

• T-Slot:
  T-Slot profiles are primarily used as modular framing systems. They are excellent for building structures like workbenches, machine frames, enclosures, and shelving. T-Slot is not designed for motion applications but excels in flexibility and rigidity for structural projects.

3. Applications

• V-Slot:
  Suitable for systems requiring motion and flexibility, such as:

  • 3D Printers
  • Laser Engraving Machines
  • CNC Machines
  • Robot Arms
  • Camera Sliders

• T-Slot:
  Ideal for modular structures and heavy-duty applications, such as:

  • Industrial Framing
  • Machine Enclosures
  • Workstations
  • Shelving and Display Systems
  • Custom DIY Projects

4. Compatibility

• V-Slot:
  V-Slot is compatible with special accessories like V-wheels, linear bearings, and motion kits, as well as standard connectors and T-nuts for structural assembly.

• T-Slot:
  T-Slot relies heavily on T-nuts, bolts, brackets, and panels for assembly. It is less versatile for motion integration compared to V-Slot.

5. Material and Finish

• Both V-Slot and T-Slot:
  Typically made from 6063-T5 aluminium alloy for excellent strength, corrosion resistance, and anodizing compatibility. Both are available in natural silver anodized and black finishes.

Summary Comparison Table

The following aluminum alloys are commonly used in manufacturing V-Slot Aluminium Extrusions due to their excellent mechanical properties, durability, and machinability:

1. 6063-T5 Aluminium Alloy

   • Features: 6063-T5 is the most common alloy used for V-Slot profiles. It offers a great balance of strength, corrosion resistance, and surface finish quality, making it ideal for extrusion and anodizing.
   • Applications: Used widely for frameworks like CNC machines, 3D printers, and other structural applications.
   • Surface Treatment: Good for both natural silver anodizing and black dyed finishes.

2. 6061-T6 Aluminium Alloy

   • Features: 6061-T6 provides higher strength and hardness compared to 6063-T5. While not as easy to extrude as 6063, it is excellent for projects requiring more robust structural integrity.
   • Applications: Suitable for heavy-duty projects, industrial automation, and robust mechanical frameworks.

3. 6005-T6 Aluminium Alloy

   • Features: This alloy offers better strength and toughness than 6063 but slightly less corrosion resistance. It’s an excellent alternative for medium-duty applications where strength and stability are critical.
   • Applications: Used in applications requiring more rigidity while maintaining good extrusion and anodizing properties.

4. 6082-T6 Aluminium Alloy

   • Features: Known for its structural strength, this alloy has excellent corrosion resistance and is weldable. Its toughness makes it a good choice for heavy-load applications.
   • Applications: Frequently employed in industrial fabrications and custom-built machine structures.

5. 1050 and 1070 Aluminium (Occasionally Used)

   • Features: These pure aluminum alloys are sometimes used for lightweight, non-structural purposes in V-Slot projects. They have excellent corrosion resistance but lower strength compared to 6xxx series alloys.
   • Applications: Ideal for decorative or non-load-bearing parts.

Why Commonly 6xxx Series Aluminum?

The 6xxx series aluminum alloys, such as 6063, 6061, and 6005, are ideal for V-Slot applications due to their:

• High extrudability.
• Great anodizing properties for surface finishes.
• Balanced strength and corrosion resistance.
• Cost-effectiveness for large-scale production.

In conclusion, 6063-T5 is the most popular choice for its versatility and surface finish capabilities, while stronger alloys like 6061-T6 or 6082-T6 are chosen for applications demanding higher durability and strength.

For custom aluminum extrusion projects, we accept a variety of drawing formats, including CAD files, STEP files, and PDF files. However, for extrusions that require additional machining processes, it’s recommended to provide STEP files, as they ensure precise 3D modeling for machining accuracy.

While PDF files are acceptable, converting them into CAD drawings may result in the loss of certain details, requiring us to manually redraw the design, which could increase lead time. For the fastest and most accurate quotation, we recommend providing CAD files (e.g., DWG/DXF) and STEP files to ensure efficient design evaluation and pricing.

Mold fees are an essential part of the custom aluminum extrusion process. Since every order requires a uniquely designed mold tailored to specific requirements, these molds cannot be used for other products. Therefore, the mold fee is necessary and non-negotiable.

We require 100% upfront payment of the mold fee before mold development begins to ensure timely production. However, as a token of appreciation for your support, we offer a refund of the mold fee or equivalent discounts once the order reaches a certain production volume. Specific policies can be discussed based on your order volume and collaboration details.

Our minimum order quantity (MOQ) varies depending on the size of the product. For smaller-sized products, the MOQ is typically 500kg, while for larger-sized products, it is 2 tons.

We will specify the exact MOQ requirements during the quotation process. If your order quantity does not meet the MOQ, we can still arrange production, but an additional fee will be applied to cover mold preheating and production setup time. Rest assured, this extra fee will be reasonable, and we aim to keep it as minimal as possible to ensure smooth cooperation.

Packaging can be customized according to your needs. Options include using protective film or paper to separate and protect the surface, or foam film for additional surface protection. Products can be palletized or packed into cartons, and the quantity per pallet or carton can be specified by the customer.

The standard packaging involves bundling several pieces together with plastic wrap and then securing them onto pallets. Any packaging requirements beyond the standard will be accommodated, and the associated costs will be clearly provided to the customer.

Mold production typically takes 7 days. After the sample is confirmed, producing a full container load of 26 tons generally requires 14 days for extrusion alone. If surface treatment is required, an additional 3 days will be needed. For machining, extra time will be required depending on the complexity and volume of the machining work. The exact additional time for machining will be determined based on the specific processing requirements.

Aluminum profiles are naturally corrosion-resistant due to the formation of a thin, protective oxide layer when exposed to air or water. This oxide layer is stable and self-repairing, meaning that even if the surface is scratched or cut (such as at exposed ends or during processing), the aluminum will not rust or corrode like iron or steel. Instead, the exposed areas will quickly form a new oxide layer, providing continuous protection against further oxidation.

With proper design, installation, and maintenance, aluminum profiles can last for decades, even in challenging environments. For example, untreated aluminum can easily withstand 20-30 years in outdoor applications, while profiles with surface treatments like anodizing or powder coating can last even longer, often exceeding 50 years. This makes aluminum an excellent choice for applications where durability and long-term performance are essential.

The price of aluminum profiles consists of several components: raw material costs, extrusion processing fees, surface treatment fees, machining costs, and additional packaging fees. Among these, the cost of aluminum as a raw material tends to fluctuate frequently, while other fees remain relatively stable. Due to these fluctuations, our quotations are typically valid for 7 days.

Pricing can be structured in different ways depending on the product and requirements. It can be calculated by weight (e.g., cost per ton), by length (e.g., cost per meter), or by piece (e.g., cost per unit). For products involving extensive machining, such as heat sinks, pricing is generally calculated on a per-piece basis to accurately reflect the additional processing costs. This flexible pricing approach ensures the quote is tailored to the specific needs of the customer.

Our production equipment is designed for the metric system. If the drawings provided are in the imperial system, we will convert them into metric units for production to ensure accuracy.

It is important to note that while we can machine imperial-threaded holes for fasteners, if you require us to supply matching imperial fasteners, they may not always be available in stock. Custom orders for imperial fasteners typically require a large volume for production. Please consider this when planning your project.
