A very high percentage of the parts for which we receive requests for quotation have never been made before. Whether it’s a flat spring, a battery contact, a wire form or a spring clip, our customers are usually fully immersed in designing a part that will fit their product and function as required. The manufacturability of their part often takes a back seat, but this is our primary concern when reviewing a new design.
The most commonly considered factors for manufacturability include the tightness of bend radii, grain direction of the material, material temper, sufficient clearance for over-bending, and the distortion resulting from the heat treat process.
One particularly insidious potential problem that often goes overlooked is part tangling and nesting. Read More →
Here at Fourslide, we manufacture most parts from flat strip material. The costs of production tooling are typically justifiable for parts with an annual usage of as few as 5,000 pieces. Despite the low volume, there is often no better or more economical way to manufacture the part.
This is not the case for wire forms. When we receive an inquiry for wire forms with lower volume requirements (fewer than 20,000), we refer that customer to a CNC wire former. Because there is usually no tooling charge for CNC wire forming, it is a more economical process for manufacturing low volumes.
When volumes increase, however, the greater production speeds of the fourslide process – which result in lower per-piece prices – overcome the initial tooling investment. Read More →
Here at Fourslide, we have long offered prototyping services for our customers. A very high percentage of the jobs we quote are for flat springs, contacts, clips, and other metal parts that have never been previously made, to be used in brand-new devices and products. We pride ourselves on helping customers make informed decisions about part design that save them both time and money.
In 1979, the federal minimum wage was $2.65 per hour; the inflation rate was 13.3%. You could buy a new Toyota Corolla for $3500 and fill the gas tank with a $10 bill. Magic Johnson’s Michigan State Spartans defeated Larry Bird’s Indiana State Sycamores in the NCAA title game. Jimmy Carter, Margaret Thatcher and the Ayatollah Khomeini were all in power.
Meanwhile, in Bristol, Connecticut, two milestone events transpired: the Entertainment and Sports Network (ESPN) took to the airwaves for the first time, and young William King made his debut at Fourslide Spring Products.Read More →
At Fourslide, multiple consecutive record-breaking years have led to longstanding discussions about the best way to support the ongoing growth of our core business. This led to a lot being purchased for the construction of a brand-new, larger facility across the street from our current Bristol, CT headquarters. But sometimes the best-laid plans are the ones that don’t materialize at all.Read More →
We’re frequently contacted by customers seeking assistance with a custom spring, clip or battery contact for their new products. Often, it’s the last item on their shopping list. The designs of other components – be it PCBs or plastic injection-molded parts – have already been chiseled in stone.
Waiting until the tail end of the design process can have some undesirable consequences. Read More →
Many manufacturers have long employed the fourslide process to produce formed parts with multiple bends and forms. Fewer, however, consider the fourslide process when faced with flatter parts, such as those pictured here.
Bryan Funk is the new President of Fourslide Spring & Stamping, becoming just the third person to hold the position in the company’s 56 year history. He succeeds his father, Arthur Funk, Jr., who followed founder Arthur Funk, Sr.
