Sheet Metal Parts: It’s All About The Process
Cutting, punching, and forming sheet metal parts within tolerances of a few hairs’ width requires both experience and the right tools. Precision Machine Fabrication has been around for almost 40 years.
In addition, we have been lucky enough to keep many of our early employees with us as we grow. Of course, over that time, technology has changed a great deal and we strive to progress right along with it.
We’re constantly adding new equipment to our already extensive collection. As a result, we can guarantee the ultimate in quality for any job that our customers require.
Punching / CNC
The first step in manufacturing sheet metal parts is to punch out any interior holes, forms, and extrusions, as well as to cut the flat part out of the sheet. Precision at this stage is especially relevant because it ensures the quality of the finished product.
The heart of our Punching/CNC Department lies in four state-of-the-art Amada machines as well as our 4,000 watt Mitsubishi CO2 laser. Our Vipros, Apelio, and EM2510 are capable of punching out shapes and creating special forms in up to 1/8″ thick steel.
Furthermore, we can laser cut up to 1/4″ thick steel with our 1,500 watt Amada Pulsar laser or up to 1″ thick steel with our 4,000 watt Mitsubishi laser. Almost all of our CNC equipment can load and unload their own material automatically, therefore allowing efficient, operator free, lights-out operation.
After a sheet metal part is punched or laser cut it often then moves to the Press Brake Department to be formed and bent. PMF is fully stocked in this department as well, currently fielding 8 machines. Our wide array of brakes range from a small 17 ton Diacro for light duty work all the way up to a 125 ton Amada for large jobs.
In 2013 we added 3 new Amada HDS press brakes to our facility. Along with Amada programming software, these machines allow us to pre-program our bending operations through our engineering department, similar to our process for CNC punching and laser cutting. Doing this cuts our overall setup time by 70% and allows us to perfect and test the bending process in a CAD environment prior to a job even hitting the floor.
More important than the equipment in the press brake department, however, is the experience behind it. PMF is fortunate to employ some of the best operators in the business. Several of our top employees have been with us for over 15 years. While other process have become more automated over time, running a press brake remains, largely, a skill. You can rest assured that no one is more skilled at forming your sheet metal parts than the operators at PMF.
If a sheet metal part requires welding, PMF is more than capable of filling that need. We are equipped with 2 spot welding stations and we also employ traditional welders who are experienced in both MIG and TIG welding practices. In addition, in an effort to lessen the cost associated with welding large quantity orders, we utilize a robotic welder, capable of precision welding long runs.
Today many of our customers look to outsource more assembly work than ever. Therefore, quality welding is imperative, as it is typically the foundation of those more complex units. Consequently, we ensure that our welders have the best equipment and the experience needed to work within the close tolerances that our customers demand.
While PMF has built its reputation fabricating sheet metal parts , we have also expanded our focus to include CNC machining. Our machine shop has always included two manual milling machines and lathes, but years ago we added a Haas CNC mill to enhance our production capabilities.
The Haas VF-2SS high speed vertical machining center allows 3 axis automated milling of aluminum, stainless, and plastic. Sometimes customers’ assemblies require a combination of both fabricated and machined parts. Therefore, having the capability to provide both services in-house is a valuable resource to our customers.
Paint & Assembly
Since cosmetic parts often require finishing before final delivery to the customer, here at PMF we have our own in-house paint facility. We use a powder coat method of painting in which we spray statically-charged powder onto metal , then bake it in large ovens until cured. Powder paint is sold in almost any color and texture and the dry paint method is much cleaner than wet paint, eliminating problems like runs and drips.
Often our parts are shipped to the customer to be assembled into the final product. However, if a customer desires a more complete product when it arrives on their floor, we have the capability to perform electro-mechanical assembly at any level- from basic to complex. Finally, we can even perform product testing to ensure that the final assembly is working properly before it leaves our facility.
