What is your material thickness handling range?

We can handle all metals and some types of plastic in thicknesses ranging from 0.001" thru 0.375" depending on material type.

What material types can you work with?

Over the past 65 years we have worked with just about every kind of "cold punchable" material. (Cold punchable means that it doesn't need to be heated before forming.) Some of the more common materials we work with include:

All carbon steels Stainless steel Aluminum Copper Beryllium Copper	Phosphor Bronze Berylco Nickel Silver Brass Most types of cold punchable plastics
All in a wide range of finishes and tempers.

Can you use our raw material?

Absolutely! We gladly accept customer supplied material. HPL can receive sheet stock up to 60" x 144", coils up to 500 lbs., and sheared strips.

How large of a part can you manufacture?

HPL's blank size capacity is 36" x 36". However, we often perform secondary stamping operations on larger customer furnished parts.

What dimensional tolerances can you hold?

As a mater of standard operation, HPL works to +/- .005". If tighter tolerances are required, we are able to hold +/- .001" when needed.

How long will the tooling last?

Indefinitely! HPL maintains all tools and engineering fixtures forever. If a tool wears out, gets dull or breaks, we fix or replace it at absolutely NO COST to the customer.

Can changes be made after tooling is done?

Yes. Because our unique short-run process uses a separate engineering fixture and set-up for each operation, changes can be made with relative ease at very little cost or schedule disruption.

Can you plate, heat treat or paint my parts?

You bet! And not only that, we offer in-house assembly operations that include: spot welding, pem nuts, stand-offs, clips, springs, custom labeling and packaging and much more. Combine all that with our high quality local vendor network and operations like heat treating , plating and silk screening can be done in days not weeks or months.

Will you accept blanket orders?

Yes. We're here to meet your needs.

Can you do split shipments?

Sure. We only ask that all parts be shipped within 30 days of completion.

Can you accept my drawings electronically?

Yes, we now have SolidWorks 3D CAD design software. Feel free to send us virtually any type of eDrawing files.
