Here at Sweeney Metal Fabricators, we’re giving prototyping timelines an incredible boost! Our team has been crafting custom prototyping projects since our shop’s inception, but now we’ve raised the bar even higher. Sweeney’s acquisition by GTR Manufacturing is more than a merger; it’s an evolution—one that allows us to now proudly offer rapid prototyping services for sheet metal parts.

Since our acquisition by GTR Manufacturing, our already successful shop is thriving more than ever before—and the biggest winners are our customers. Now integrated with the GTR brand, Sweeney is a true one-stop shop for customers seeking a full range of precision metal fabrication services in the Northeastern US.

Thanks to Sweeney Metal Fabricator’s recent acquisition by GTR Manufacturing, customers now have access to an all-new range of in-house finishing capabilities. Keep reading to learn about the options available and the advantages of working with our New Hampshire metal fabrication shop.

Here are a few of the most common areas where we see customers over-engineering their parts and driving their costs through the roof.

Driven by our commitment to growth and innovation, Sweeney Metal Fabricators is excited to announce that our New Hampshire metal fabrication shop has joined the GTR Manufacturing family! Our acquisition by GTR radically expands our capabilities, empowering our customers with one-stop access to a comprehensive range of manufacturing solutions and providing our expert team with continued opportunities for success.

No one starts a new job expecting their insights to be ignored, their ideas dismissed, and their talents taken for granted. Yet, in so many workplaces, employees experience those very frustrations day after day.

How could anyone ever confuse one material with another? You may be surprised to learn that people make this mistake regularly, especially when ordering parts made from aluminum alloy. Customers most commonly mix up two popular aluminum alloys: 5052-H32 and 6061-T6.

When you need a fast quote for metal fabrication, New Hampshire shop Sweeney Metal Fabricators is here to deliver. Our team provides most quotes within 24 hours of receiving a request!

Chromate conversion coating, Alodine®, yellow Bonderite®, Iridite®, chem film, “chromating,” and chromate treatment all indicate the same thing–and that “thing” is the passivation of aluminum, cadmium, copper, magnesium, steel, tin alloys, and zinc.

If you order the same parts week after week or month after month, you’re probably a great candidate for our Vendor-Managed Inventory (VMI) program.

Does your part need 5-axis machining? Or can a 3-axis machine get the job done while ensuring the same level of quality? It’s wise to determine the answer to this question before spending extra money for a precision machine shop to use 5-axis technology.

“That’s the way we’ve always done it.” Processes and routines are healthy elements of an efficient business. But machine shops that cling too tightly to “the way we’ve always done it” risk falling behind, losing their edge, and failing their customers.

Sheet metal fabrication involves manufacturing parts out of metal. CNC machining involves manufacturing parts out of metal. So aren’t sheet metal fabrication and CNC machining the same thing?

You have a clear product concept, but you need help finalizing a design that’s cost-effective and efficient to manufacture at volume. Sweeney Metal Fabricators helps project managers and mechanical engineers bring important ideas to life by partnering with their teams to optimize designs, build prototypes, and manufacture high-quality parts and products with repeatability.

We want the precision metal fabrications we make for you to be as close to perfection as possible. To achieve this goal, however, we need a detailed RFQ—the easy, online Request for Quote form that initiates your estimating process.
