Frequently Asked Questions

What is Metal Spinning?

Metal spinning, also known as metal turning, is a high-performance metalworking process that creates axially symmetric metal parts. Spin forming is unlike other metal forming processes that cut and remove material to produce the desired shape. The right metal spinning equipment and metal spinning tools transform a metal disc or tube into a quality spun finished piece.

What is the Advantage of Robotic Welding over Manual Welding?

Robotic technology delivers more precise, consistent results than traditional, manual welding methods. The process also tends to be much faster, delivering good quality results on a tight turnaround. The latest technology in the robotic welding process offers you maximum speed, flexibility, and efficiency compared to traditional welding techniques.

What diameter of blanks can be spun at Glenn Metalcraft Inc?

At Glenn Metalcraft, we have industry-leading metal spinning machine capabilities to suit a full range of design requirements. Our metal spinning machinery can handle parts ranging from the thinnest gauge up to a maximum diameter of 48″. All our products are assessed for quality-control inspection to guarantee a high-quality finish every time.

What shapes can be formed with metal spinning?

The metal spinning process can form all sorts of shapes, depending on your specific preferences and requirements. Hemispherical, venturi, cylindrical, conical, parabolic, and toroidal shapes are all possible with metal spinning or spin forming.

What is Powder Coating?

Powder coating is a unique type of coating that uses electrostatics to apply a powder to metals. It’s a high-quality, UV ray-resistant method that creates a glossy finish and works on nearly all types of metal.

How Does E-Coating Work?

E-coating is a highly innovative process that uses an electrical current to bind wet paint particles to a metal surface. This process occurs when an object is plunged into a water-based solution or what’s referred to as a bath. This bath usually contains 80% deionized water and 20% paint resin solids.

You can choose different coverage thicknesses, and the electric current is altered accordingly. When the part comes out of the bath, the extra residue is rinsed off and returned to the e-coating tank, reducing waste and saving money. As with powder paint, the part is then cured to harden the paint.

Is Powder Coating Better Than Liquid Paint?

Generally, powder coating is better than liquid paint because it’s three times stronger than solvent-based paints. Not only that, but it simultaneously covers larger areas for a better price. It creates a uniform and high-quality finish while remaining more resistant to corrosion, chemicals, and weather than liquid paint.

What is CNC machining?

CNC machining is a subtractive manufacturing process that typically employs computerized controls and machine tools to remove layers of material from a stock piece- known as the blank or workpiece- and produces a custom-designed part.

What is the difference between turning and milling?

Turning is a machining process where a lathe removes material from a rotating workpiece with a cutting tool. With turning, the workpiece moves while the cutting tool remains stationary.

Milling is a machining process where a machine removes material from a stationary workpiece with a rotating cutting tool.

What is fabrication?

Metal fabrication is the creation of metal structures by cutting, bending and assembling processes. It is a value-added[1] process involving the creation of machines, parts, and structures from various raw materials.

Typically, a fabrication shop bids on a job, usually based on engineering drawings, and if awarded the contract, builds the product. Large fab shops employ a multitude of value-added processes, including welding, cutting, forming, and machining.
