Posted by Metal Craft on | Comments Off on Metal Craft Chosen to Spin 2019 Good Deeds Cup
The Chevrolet Hockey program aims to inspire positive values in young Canadians through hard teamwork and sport and also encourages the participants to perform positive deeds in their communities. The program enables Chevrolet to donate to causes across Canada on behalf of Peewee hockey teams. Players have performed hundreds of good deeds since the 2016/2017 culmination. Good deeds encouraged by the program include voluntary work at food banks, visiting an animal shelter, or driveway shoveling in the community.
However, the activities involved are limitless, as players are free to come up with and implement any suggestions. Good Deeds Champions receive different prizes, including the coveted Chevrolet Good Deeds Cup with the team’s name engraved. But how exactly is such a celebrated championship cup designed and made?
The Good Deeds Cup Design
Hockey Canada approached Jimmy Rogers of 39 Design and Engineering Inc. to design the Chevrolet Good Deeds Cup. He then contacted Metal Craft Spinning and Stamping to spin the cup portion of the trophy itself. This unique project allowed us to showcase our manual metal spinning capabilities while supporting a worthwhile charitable program.
The client asked us to fabricate the Good Deeds Cup from brass. This metal comes as a flat sheet with excellent formability properties, allowing for a smooth transformation into a cup. While brass is already a ductile metal, for this project we put it through several annealing cycles to make it more malleable. The annealing process involves treating the metal with heat to increase its ductility, but multiple rounds of annealing were necessary as brass heats up rapidly and gets hard quickly.
To create a high-end, long-lasting cup, we turned to our senior metal spinner, whose 30 years of hand spinning experience was the perfect match for the project. Our senior metal spinner has handled a wide range of complex pieces over the years, which means he could handle any issues that may arise to produce an exquisite masterpiece.
Since the end product was only one piece, the operator chose a hand spinning lathe instead of a CNC machine. Aside from the low volume, a hand spinning lathe is also ideal when you need maximum control. Manually spinning the piece allowed our senior metal spinner to feel the flow of the material.
Crafting this sophisticated piece required significant preparation and time. The spinner took five hours to produce the Good Deeds Cup. It was then polished and shipped to our client.
About Manual Metal Spinning
A typical hand metal forming process takes the following steps:
The operator mounts the mandrel chuck to the headstock. He then fixes the blank in position by advancing the follower block attached to the tail’s headstock.
A combination of a tool rest and pin serve as a support system for the lever arms. This arrangement gives the lever arms enough leverage to apply sufficient pressure to the blank against a forming tool like a roller.
A pass in manual metal spinning refers to one movement of the roller across the blank’s surface. The operator needs to run multiple passes to form one complete part. This can be achieved by increasing the pressure on the blank using the lever arms gradually to reduce the blank into the desired form.
For mass production and repeatable precision in large volume metal forming, Metal Craft Spinning & Stamping uses our CNC metal spinning machine rather than a hand lathe. This technology automates the passes, transforming the blank disc into intricate pieces within minutes.

Posted by Metal Craft on | Comments Off on Bringing Metal Spinning to The Modern Age
Metal spinning has evolved significantly over the years. Though the concept remains the same, modern equipment and advanced technology have transformed the process into a more viable and affordable option for the manufacturing industry.
What Is Metal Spinning?
is known by many names, such as spin forming, spinning, and metal turning. Regardless of the name used, it is a metal forming process which rotates a tube or disc of metal at a high rate of speed to produce hollow objects or components. A common factor in these hollow objects is their typically circular cross section.
The best uses of metal spinning include creating prototypes and manufacturing parts which require high internal and external pressures.
Traditional Metal Spinning Process
The basic concepts of the metal spinning process have not changed a great deal since spinning was first introduced as a manufacturing tool. The essential steps include:
Mounting a mandrel chuck on the headstock of the lathe.
Mounting a follower block to the tailstock.
Clamping of a circular blank by advancing the follower.
Pressure is applied to the blank via a roller or other forming tool on the lever arms, using the tool rest and pin to provide scissor-like support and leverage to the lever arms.
The roller moves across the blank in a series of passes until it forms the completed part.
Modernization of Metal Spinning
Manual metal spinning, which came to North America in the early 1800s, has evolved into a more modern process. The technological advances of our modern age have combined to automate the process, making it faster and improving repeatability. As such, automation has made metal spinning an even more reliable and cost-effective manufacturing option.
Automated metal spinning makes use of computer numerical control (CNC) in place of hand spinning. CNC is a method of subtractive manufacturing technology, which follows a computer aided design (CAD) model along with a variety of cutting tools to remove material from a blank in order to produce the desired component. The major advantages of CNC spinning over hand spinning include:
Higher level of accuracy and consistency over an entire production run
The mitigation of human error risks through the autonomy of CNC machining and reduced touches.
The necessity of fewer personnel for high capacity production runs
24/7 operation using machines, which cuts back on manpower and operating costs.
Besides these advantages, CNC metal spinning allows for the turning of a broader range of materials than hand spinning, including less malleable materials. The materials formed using CNC spinning include:
This broad range of metals allows for a wider variety of manufacturing options and broadens the range of potential industrial applications which the process might serve. With CNC providing a more cost-effective option for producing parts, along with greater accuracy and consistency, it makes good business sense to incorporate it into your fabrication process when relevant to your design.

Posted by Metal Craft on | Comments Off on Spinning, Stamping, and Hydroforming: Which Works Best for Your Application?
Most manufacturers consider metal spinning, metal stamping, and hydroforming to be specialized and narrowly focused processes, but actually, these metal-forming methods are used in industries as varied as commercial construction, interior design, heating and climate control, and agriculture. Manufacturers use spinning, stamping, and hydroforming methods for products ranging from satellite dishes to funeral urns.
Understanding the benefits of each process as well as where they overlap will help you decide which metal forming technique best suits your application. Below, we’ve assembled an overview of the three main metal forming practices, and we also outline the ways they could benefit your production line.
Metal Spinning
Metal spinning, also known as metal turning or spin forming, is a fabrication process that uses a rotating spindle to form metal into axially symmetrical, hollow cylindrical products or components. The process can be automated using CNC technology, manual equipment, or hydraulic controls, and is used for shaping ductile, formable metals such as aluminum, copper, and brass.
The metal spinning process is highly efficient and inexpensive, which makes it particularly useful for large-scale production runs. Since the tooling can be easily modified, adjustments can be made during production with minimal expense and downtime. In addition, the process produces very little material waste, further reducing production overhead.
Metal spinning is used to create products with diameters as small as 1” and up to 8’, which allows manufacturers to create a variety of products, including musical instruments, mixing bowls, automotive components, lighting fixtures, roofing, and satellite dishes.
Metal Stamping
Metal stamping uses compressive force and pre-formed dies to create shapes from a flat metal sheet or blank. It is a highly efficient process that is easily automated and requires very little labor when compared to other fabrication methods. At its most basic, the metal stamping process involves feeding a sheet of metal between a press and the die tool. When the press is activated, it applies pressure to the metal, forcing it into the die to create the desired shape.
Although the overall stamping process is simple, it requires the use of highly specialized equipment, depending on the product. To facilitate efficient and accurate fabrication, manufacturers have developed a variety of stamping techniques, including progressive, deep-drawn, and fourslide stamping, among others. Each method is engineered to produce specific products and parts.
Metal presses can be used to create a variety of shapes and useful features through punching, bending, notching, and embossing. The versatility, accuracy, and repeatability of the metal stamping process make it ideal for manufacturing automotive components, farm equipment, fixtures, brackets, and ventilation system components.
Hydroforming
Hydroforming is a metal fabrication method that uses pressurized fluid to shape ductile metal into components using pre-shaped plates or dies. A tube or flat sheet of metal is placed inside the hydroforming chamber along with the die. The hydroforming press forces water into the chamber, pressing the tube or sheet against the die to create the intended shape.
The hydroforming process offers a variety of advantages over other methods, particularly for shaping highly complex, intricate, or asymmetrical components from tubes of ductile metal. By creating components from one solid piece of metal, hydroforming produces stronger, seamless shapes with exceptional stiffness and durability. In addition, hydroforming allows manufacturers to create components using a one-step process, thereby reducing production time and increasing the amount of material that can be processed at a time.
As a highly cost-effective and efficient manufacturing method, hydroforming is favored by manufacturers for lighting fixtures, satellite antennae, and a variety of automotive components.
