What is the Expected Life of Fourslide Tooling?

Fourslide tooling is a truly Non-Recurring Expense.
Fourslide tooling is a truly Non-Recurring Expense.

We’re often asked this question after prospective customers receive a quotation. The answer is quite simple: your Fourslide tool’s life is the same as the life expectancy of the part it’s making.

Tooling built by Fourslide Spring & Stamping is truly a Non-Recurring Expense. All maintenance, repair, and even replacement of the tooling are free of charge. So long as the design of the part remains the same, the customer never pays another nickel in tooling charges.

Choosing a Material for Your Flat Spring, Spring Clip, Contact or Other Metal Part

Selecting a material for your custom metal part

We are often asked to recommend a material for a customer’s flat spring, spring clip, battery contact, or other custom part. The standard response is that we do not make material recommendation, because the application requirements (e.g., spring force, conductivity, range of motion and corrosion resistance) are so critical to material selection. Our expertise lies in the manufacture of springs and stampings, not the design of the part for its intended function.

Rather, we suggest the materials that are viable alternatives relative to the manufacturability of a part. Many part geometries can be accomplished utilizing spring-tempered materials such as stainless steel, spring brass or phosphor bronze. When possible, these are preferable because they do not require heat treatment subsequent to forming, a process that can cause part distortion.

Considerations for Prototyping Metal Parts

Complex parts benefit greatly from the prototype process
Complex parts like this one benefit greatly from the prototype process in determining final feature geometry.

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.

Contact Us Early in Your Design Process

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 →
