Posted by Metal Craft on | Comments Off on Aluminum vs. Steel
Steel and aluminum are materials found in virtually every industry for a variety of industrial and consumer products. While they look similar, there are considerable differences between the two. In this blog, we’ll discuss both materials and their differences to help you determine the best one for your application.
Strength and Malleability
Aluminum is more elastic and ductile, allowing it to be bent, extruded, or stretched without cracking or breaking. It increases strength in colder environments, although it is susceptible to dents and scratches. In contrast, steel is tough and resilient but has the added risks of rust and corrosion, as well as cracking or ripping during spinning due to reduced malleability and ductility. However, it is a much harder and more durable material than aluminum, making it resistant to bending or warping from heat, weight, or force, or heat.
Weight
Aluminum vs. steel weight is a significant determinant in which material is preferable for applications where every extra pound can decrease speed, aerodynamics, and fuel efficiency. In those applications, aluminum is clearly superior as it is lightweight, easy to handle, and less expensive to ship. When durability is the primary concern, the weight of steel makes it the optimal choice due to the high concentration of carbon that results in 5x the weight and density of aluminum. However, shape and structural rigidity are other significant factors in the strength of a material, making aluminum a viable option at half the weight of steel.
Corrosion Resistance
Aluminum reigns supreme for corrosion resistance without additional treatments for protection after being extruded due to a naturally occurring oxide film that is an inhibitor to rust. Various optional finishes can enhance aluminum’s aesthetic appeal, such as brushing, painting, powder coating, anodizing, painting, media blasting, polishing, or chemical washing. In contrast, steel must be treated or painted to get the same level of protection from rust and corrosion. If steel is required for applications exposed to moisture, humidity, or abrasion, it must be treated appropriately to keep it from degrading.
Cost
When comparing stainless steel vs. aluminum cost, steel is frequently less expensive per pound than aluminum. However, the price of metals fluctuates constantly depending on fuel costs, price and availability of bauxite ore and iron, and global supply and demand. The price of steel can also depend upon the type. Carbon steel and mild steel are generally less expensive, while the cost of stainless steel can exceed that of aluminum.

Posted by Metal Craft on | Comments Off on Venturi Valve: What You Need to Know
What Is a Venturi Valve?
A venturi valve is an hourglass-shaped tube, with either end of the valve having a wider diameter than the narrowed center. Inside the valve is a cone that moves parallel to the body of the valve. As pressure within the valve changes, the cone moves forward or backward to modify flow rates through the valve assembly.
Venturi valves are specifically designed to provide flow regulation in response to pressure changes. HVAC ducts use venturi valves as airflow control valves to regulate and maintain airflow through the system. Unlike other methods, the venturi valve independently regulates airflow in response to changes in static pressure, without the need for communication between system components. The independence and fine control offered by venturi valves makes them ideal for maintaining both constant and variable airflow based on external conditions.
Venturi Valve Options
Venturi valves are available in a variety of factory-programmed calibrations to meet the specific requirements of numerous applications. They can be composed of a wide range of materials, including aluminum and steel, and are often treated or coated to enhance strength, chemical resistance, and corrosion resistance. Thermal insulation can also be added to the valve to reduce thermal loss and increase energy savings. Numerous valve flow designs are available depending on the needs of your application.
Constant and actuated valves are the two most common venturi valve designs. Constant volume venturi valves are engineered to provide a steady flow of air or fluid through the valve, regardless of duct pressure fluctuations. They are best suited for outdoor airflow regulation, ventilated cabinets, and biological safety cabinets. Actuated valves are typically used in dynamic systems where quick valve operation is critical. They use a cone situated on top of a shaft to restrict the flow of air through the valve opening to ensure consistent control.
Advantages of Venturi Valves
Venturi valves offer a variety of benefits for a wide range of applications and industries, including hospitals, universities, biological safety cabinets, and laboratories. They are incorporated into ventilation and HVAC systems to provide consistent, accurate control of pressure, temperature, and airflow.
Venturi valves are highly sensitive and operate independently, making them quick to respond and reducing the need for extensive room pressurization testing. They react extremely quickly to signals, making them perfect for sensitive operations in labs and ventilated cabinets.
Some venturi valve designs incorporate full shutoffs, which will keep the valve closed when not in operation in order to save energy. This energy efficiency is compounded by thermal insulation, which reduces thermal loss.

Posted by Metal Craft on | Comments Off on Why Use Metal Spinning for Furniture Applications?
Metal furniture and fixtures offer stability and strength, especially for rounded bases and tubular structures. Metal spinning—also known as spin forming or metal turning—is a technique that shapes these parts by taking a flat piece of metal, usually in the form of a disc, and molding it to fit a form as that form and disc spin at high speed.
These spun-metal products have clean, sleek lines and smooth surfaces that are strong and durable. They are commonly used in many decorative items and commercial and industrial products, ranging from lamp bases to candlesticks to furniture and table legs. Metal spinning is a highly customizable process, allowing both artisans and automated lines to produce accurate forms.
Why the Furniture Industry Uses Metal Spinning
Metal spinning is a perfect match for the furniture industry, as there is little to no waste (cutting, grinding, etc) when metal is spun into a shape. The process of metal spinning for furniture is relatively swift, if automated, and produces durable items.
You can create almost any rounded shape with metal spinning as long as you find a suitable blank form. The spinning can be done by hand to form unique items or by mass production to create several identical forms of one shape. Either way, the process is very versatile and cost-effective. For the furniture industry in particular, metal spinning produces aesthetically pleasing pieces without breaking a company’s budget. This is essential for furniture manufacturers who want to mass-produce items.
How Metal Spinning Is Used in the Furniture World
Any time you see a rounded base or a tubular structure made of metal, especially steel, copper, brass, alloys, or aluminum, you’re likely looking at a piece that was formed through metal spinning. These include bases for:
Lamps
Flag Poles
Crowd barriers
Stools, chairs, and table legs
Display stands
Lids (e.g., metal trash can lids)
Metal spinning is also used for tubular lamp shapes, candlesticks, vases, and similar items.
Metal spinning using CNC machinery is another matter. This combination of metal spinning and computer-controlled tools produces nearly identical items with specifications that are all within a certain tolerance. This is the path you want to take if your company plans to mass-produce items for sale.
Metal Craft Spinning & Stamping for All Your Metal Spinning Needs
You can form round bases and tube-like forms for furniture and fixtures through a number of methods, but metal spinning offers the best value. It is efficient and allows individuals and companies to create products that are both attractive and practical.
Metal Craft Spinning & Stamping provides metalworking services in both the U.S. and Canada

Posted by Metal Craft on | Comments Off on Metal Spun Bases; What You Need to Know
Metal spinning is a technique for fabricating parts with a circular cross-section from a flat metal disc or cylinder. Metal spinning is also often referred to as spin forming or metal turning. Metal spinning is commonly used in the fabrication of various metallic bases for a wide variety of commercial and industrial goods.
Where Are Metal Spun Bases Used?
Metal spun bases are a natural fit for applications requiring a symmetrical, round component as a base or for finishing. They are widely used in the following applications:
Bases for mannequins and display stands in the clothing industry
Flag stands, pole bases, or fencing bases for construction projects
Bases for chairs, tables, bar stools, and various restaurant furniture
Display cases and stands in grocery and retail stores
Aluminum, brass, copper, steel and metallic alloys are all used to make spun bases. Metal spinning with computer numerical controlled (CNC) machines can produce various bases from any of these metals with strict tolerances.
Furniture manufacturing uses metal spun bases for their visual appeal as well as robustness. Steel is usually the metal of choice for furniture manufacturing due to its machinability and strength. Steel parts are also very durable even under fluctuating ambient conditions and high loads. Furthermore, steel parts have an appealing finish that can be maintained for a long time through simple and easy cleaning methods.
Aluminum and brass are used for products that need a high polish—aluminum is used for commercial products while brass is more suitable for decorative purposes. Copper is appropriate for light fixtures and roofing parts due to its high thermal conductivity.
Advantages of Metal Spinning
The main advantages of metal spinning are as follows:
Low waste. Spinning generates much less waste than other manufacturing methods and the generated scrap can be easily retained and recycled. This is true for manual spinning as well as precision spinning with CNC machines.
Reduced costs. Spinning tools cost a much less than the tools used in other manufacturing processes, giving metal spinning a cost advantage over competitive forming methods.
Durability. Spun parts are essentially a single piece with no seams which makes them very sturdy and durable.
Speed. The short turnaround time and flexibility of the spinning process makes it an attractive and economical process for volumes ranging from prototyping through high volume production.
Versatility. Though the process is simple, it can be used for fabricating a wide variety of shapes. Basic spun shapes such as dishes, domes, flanges, hemispheres, and whole spheres can be combined to make more complicated shapes. A virtually endless variety of products of differing shapes, sizes, and finishes can be fabricated when spinning is used in combination with welding.
Metal Craft Spinning & Stamping has been in the metal spinning business for more than 50 years. We are skilled at hand spinning, as well as spinning with modern CNC machines. We also have in-house hydraulic metal stamping presses, enabling us to meet a broad variety of metal forming needs. Metal Craft can be your one-stop shop for bases, stands, and other metal products.

Posted by Metal Craft on | Comments Off on 5 Tips to Optimize Your Metal Spinning Design
Similar to the way a potter fashions a bowl or vase from clay on a spinning pottery wheel, metal can be spun on manual or CNC lathe to produce a variety of parts and components. Metal spinning is an advantage when you need seamless items or particularly strong structural parts. The process is ideal for production volumes ranging from short-lead prototypes to mass production.
With metal spinning, pieces of flat circular metal are carefully shaped into disks that can be further modified to make common items such as:
Stainless steel bowls
Commercial lighting
Brass instruments
Gas cylinders
HVAC Parts
Roofing parts
Aerospace parts
Satellite dishes
Exact shaping of the metal is dependent on additional tools used with the lathe, such as the complex rollers that smooth the metal form over mandrels. Nearly any type of metal can be used for metal spinning, including brass, copper, aluminum, carbon steel, stainless steel, or titanium. When cold form manipulation doesn’t produce optimal results, heat can be applied to improve the workability of the metal as it is spun.
Best results may be achieved by carefully following the best practices for metal spinning planning and design.
1. Define Object Function
If you don’t know exactly what you’re designing, you’re more likely to waste time and materials during the spinning process. It’s important to note that metal can only be spun on both circular or semi-circular shapes, so the process can, in fact, work for designs that require sharp corners. Once the final goal is determined, a design can be created that will leverage metal spinning’s precision and customizability.
2. Pick Your Material
Metal spinning works with a variety of metals, but selecting the appropriate materials for your specific job will ensure the best results and minimize wasted metal. Different metals can have vastly different end results, depending on the thickness you wish to achieve.
Very small changes in diameter or thickness can make a part unusable for your engineering project. In addition, some metals are more likely to get rigid as they are spun. Knowing what metal is best for your application and using a material that’s well-suited to your needs will ensure optimal end results.
3. Consider Material Thickness
Depending on the type of metal you use and the height of the sidewalls, the sidewalls of your object will thin and could vary as much as 25%. You’ll need to carefully consider the amount of pressure you apply from the mandrel to the raw metal.
A larger corner radius will be easier to create and stronger than using tighter corners, so you’ll want to avoid sharp corners in your finished part. The formed radius of the end object should be at least 2–3 times the material thickness for best results. The radius in the corners can in some cases equal the metal thickness, but may vary as much as 30%. The thickness of the bottom will be of equal thickness to the original metal blank.
4. Specify Your Tolerances
Metal spun parts don’t necessarily need consistent thickness throughout. Designs should also note that part diameter can be impacted by roundness and flatness. In parts that are less than 1 foot in diameter, a tolerance of +/- 0.005 inches may be achieved. Less than that diameter, you can expect +/- 0.01 inches, while 2–4 feet requires +/- 0.02 inches and 4–8 feet must have a tolerance of +/- 0.03 inches.
Manufacturing your metal-spun part from a tolerance of +/- 0 .01 of an inch for every foot in diameter is an achievable goal.
5. Cost Factors
Many metal forming methods are not cost effective at low volumes, but you can save time and money by metal spinning prototypes or a short runs. A cost/benefit analysis can help you identify savings for your unique design, especially considering different tolerances or sizes. Creating parts is fast with metal spinning so lead times may be shorter, but it’s important to create a design that facilitates fast and accurate production.
Parts created through metal spinning can be made smaller if needed and are often stronger than those created through other processes. Spinning may improve the properties of the raw metal by aligning the grain structures of the metal more advantageously for your application. Depending on the exact use case, metal spinning can be a more cost-effective way to create one-off parts and prototypes than other metal forming methods.

Posted by Metal Craft on | Comments Off on Advantages of CNC Metal Spinning vs. 3D Printing
CNC metal spinning and 3D printing are two manufacturing techniques used to create identical custom parts. While the end products can often appear similar, the mechanisms behind the processes and the quality of the end products are vastly different. Before finalizing your next part design or production order, it is important to know and consider the differences between the speed and price of two processes so that your team can choose the right manufacturing method for your application.
Speed & Price
First and foremost, metal spinning outperforms any existing 3D printing methods in both turnover rate and unit cost for both long and short run orders.
CNC spinning operations can form a product according to the designs faster than 3D printers can build the parts from an existing blank. 3D printed parts have to be run through additional steps before they are ready for distribution. These additional steps include removing supports required during the creation process, washing and polishing the products, and a curing period (to ensure the product is solid and the layers bind together).
The additional processing required for 3D printed parts increases the turnaround time, making 3D printing less efficient and cost-effective than CNC metal spinning. When speed matters, CNC spinning is the better choice. With this process, operators can also control production time by prioritizing speed over accuracy and vice versa.
CNC metal spinning is also the ideal choice for mass production. 3D printed pieces cost the same per unit, which can offer some advantages for prototyping and small orders. However, it is not suitable for large production runs. CNC spinning, on the other hand, is a process that can quickly scale up for lower per unit prices on larger orders.
Size, Precision, and Purpose
CNC metal spinning is a forming process that takes a stock piece of material, or blank, and forms the material to reach the final design. 3D printing, on the other hand, is an additive process that builds the product layer by layer. Although the characteristics of each process make them suitable for particular applications, CNC Metal Spinning offers advantages over 3D printing in regards to size, precision, and purpose.
Size
Industrial and commercial equipment, engines, and machinery are large systems that require proportionally large components. While CNC metal spinning processes can quickly produce large and heavy parts, as an additive process, 3D printing is less suitable for producing large parts as the material layering process takes considerably more time than the material removal process used in CNC spinning. Although 3D printed products can be scaled up from small prototypes, they generally do not exceed the dimensions of a small refrigerator.
Precision
CNC machine tools produce smoother edges and surfaces compared to those produced by 3D printing processes, enabling the production of higher quality parts that do not require further processing operations.
Purpose
Due to their rougher finish and other limitations, 3D printed components work best as fit and finish parts. On the other hand, the smoothness of CNC spun parts’ surface enables them to be used with precision components and tools.

CNC metal spinning outperforms 3D printing when it comes to speed, precision, and smoothness. It is suitable for manufacturing large and heavy components and large production runs. Even with Selective Laser Melting (SLM) 3D printing technology, which allows for the creation of metal products, the results cannot match the accuracy and speed of CNC spinning.
Since 1964, Metal Craft Spinning & Stamping has provided CNC metal spinning capabilities for the manufacturing of metal components.
Posted by Metal Craft on | Comments Off on How Venturi Valves Can Optimize Your HVAC Air Flow Performance
Heating, ventilation, and air conditioning (HVAC) systems are essential components of commercial and industrial structures. However, more than just warming or cooling a designated space, HVAC systems are designed to improve air quality and ensure maximum comfort for anyone inside the building.
Variable air volume (VAV) systems or boxes are a common component installed for a commercial or industrial structure and perform a converse operation by supplying variable air flow to different spaces within the building at a constant temperature.
VAV boxes are an important component of any VAV system, as they have strategically placed calibrated dampers that control airflow to specific locations within a building. Although many commercial applications use VAV boxes, these systems often come with their fair share of problems. Some issues with VAV systems include:
Time delays between the VAV box airflow sensors and controls, causing frequent adjustments
Loss of efficiency within the structure’s VAV system and HVAC components.
Dirty airflow sensors result in efficiency loss, causing routine checking and cleaning
Adjustment delays between system components
Airborne risks in critical or hazardous applications
Manufacturing environments, laboratories, and other environments that rely on proper ventilation to safely remove harmful microorganisms or particulates from the air need a more thorough solution
The Venturi valve offers a more responsive solution for these critical applications, and are specifically engineered to facilitate superior regulation of air flow. Instead of relying on signals from the VAV system to adjust to changes in air pressure, Venturi valves measure pressure independently from the system and adjust without waiting for signal exchanges between system components, providing immediate airflow adjustments with ± 5% accuracy.
