Whether you need steel bulbs, gaskets or disposable pod cups for your e-cigarette business, you need to find a fabrication shop that specializes in deep drawn parts, such as Precision Stamping. Not every shop can generate large orders of these, as they require special machinery to stretch sheet metal into the cylindrical shapes you require. Consider using this list of questions to seek out the right experienced shop.
Which Materials Have You Worked With?
A shop's list of past clients and orders should help you know something about whether their work will stand up to use. If they're not used to filling orders for titanium inserts for medical devices, for instance, they might not understand what precisely you need in the way of durability, thickness and other features. Ask about work they've done for other fabrication projects so you're sure they will work easily with your requirements and ideas.
You also must ask about materials they're familiar with because you may not be completely confident about the materials necessary for your work. You might have conceptualized a shiny steel bulb for the interior of your product, but perhaps a lower-costing cold-rolled bulb would work fine. Being knowledgeable about your industry and metal pieces should permit shop techs to guide you instead of letting you guess about what's right. They could have some design and shape ideas which improve your overall work and make superior pieces.
Do You Offer Multiple Finishes?
You may require more than simple polishing on your deep drawn parts. For instance, if you're using the pieces for "smokeless" or e-cigarettes, you will likely need a finish that will deal well with smoke and residue. If you're having gaskets made for industrial use, blackening might be the best finishing choice because it will repel corrosion. A good shop that has a suite of finishing options is important; if you plan to order more pieces later for other uses, those multiple options are imperative.
Will You Check All Designs?
No matter how hard you and your staff work, there's a small chance that you've miscalculated thickness, size or ratios. For that reason, it's essential to have shop techs who will catch these errors even if you've mistakenly sent them through. Whether they will fabricate samples or contact you with questions, having more people who care about your finished product will give you a better feeling about placing large orders. You won't need to fear delivery of dozens of incorrect metal pieces.
With these questions, orders for deep drawn parts will turn out well. Have discussion meetings with multiple shops to find the best.
