CNC Fabrication in Fresno CA by Purl's Sheet Metal & Air Conditioning

Purl's Sheet Metal & Air Conditioning was started in 1952, before there were computerized machine tools. But at Purl's Sheet Metal & Air Conditioning, we’re not stuck in the past. We recognize that new technology has allowed us to produce high quality work faster and more accurately. We use some of the most advanced CNC machines to fabricate our customers’ projects.

All of our technicians are highly trained and have years of experience working on a wide variety of projects for businesses and customers of all types. We are committed to two things: our customers’ satisfaction and to the quality of our workmanship. We want you to be completely happy with the product that you get from us. Call us today to see how we can work together on whatever project that you have for us.

How Do CNC Machines Work?

If you have a printer attached to your home computer then you have a type of CNC machine. Printers only operate on the X axis which is how they move the ink carriage back and forth across the paper as they print out the letters. The CNC machines that we use at Purl's Sheet Metal & Air Conditioning are obviously much more complex but the principle is the same. We use a computer program to design our customers’ project. We load the design and the fabrication instructions into the CNC machine. From there, we let the machine do the rest of the work as it cuts out the customers’ design in the metal.

Types of Projects That Use CNC Machines

You can use CNC machines to design virtually any type of item imaginable. At Purl's Sheet Metal & Air Conditioning we offer a wide range of sheet metal fabrication services from ventilation to racing. Here are a few of the services that we offer.

  • All types of roof and chimney flashings
  • Spiral ductwork
  • Irrigation and agricultural products (custom hydrants, agriculture process ventilation and more)
  • Industrial piping
  • Custom ductwork
  • Rain gutters
  • Custom designed metal products
  • Copper and stainless steel range hoods
  • Stainless steel countertops and backsplashes
  • Clean room filtering systems

Benefits of Custom CNC Products

Not all homes and businesses are the same. While standard equipment may exist for a wide range of applications, having a piece of equipment specifically designed for your particular application is almost always better. For example, residential and commercial ductwork comes in a few standard sizes. But those sizes don’t always fit through the attic or basement spaces of every home. Without custom ductwork it can result in unnecessary bends or pitches in the ductwork. The same is true for irrigation products, gutters, piping and a host of other products. Additionally, custom designed products that are highly visible, like range hoods, counter tops and rain gutters, typically look better when they have been carefully made by a skilled professional.
