What is the difference between metal stamping and sheet metal fabrication?
Metal stamping can refer to any of a number of metal forming operations—in addition to stamping, bending, pressing, folding, and stretching actions may be used to produce the final part. All metal stamping processes utilize punch presses with custom-made tooling and dies to produce a shape, pattern, or other characteristic a part requires. In general, the stamping process can provide tighter tolerances than sheet metal fabrication. It is a fast and cost-effective way to produce metal parts in large quantities.
Sheet Metal fabrication entails the manufacturing of three-dimensional metal parts via cutting, bending, and/or other assembly processes. Fabrication generally requires more specialized equipment, such as CNC laser cutters, CNC press brakes, CNC turret presses, and welding. Sheet metal fabrication is often the more economical way to produce parts in lower quantities, as the tooling associated with stamping can be costly. Fabrication also provides greater design flexibility than stamping, as there is no tooling to change should your part design require alteration.
What other information is needed besides prints when I submit the RFQ for sheet metal ?
When you submit your RFQ (Request For Quote) via email or fax, please let us know the following:
(1) 2D drawing in PDF, DWG, DXF format.
(2) 3D drawing in STEP, STP, IGS, X_T format.(For simple parts it is not a necessary, for complex parts, it is necessary to have 3D drawing)
(3) Material information
(4) Surface treatment/finishing information
(5) Batch quantity/ (Annual Usage if Available)
(6) Product application/industry ( this is helpful to consider the best solution for cost)
(7) Any special requirements if not annotated on print (Example: Specific Packaging Requirements)
What are your minmum order quantities(MOQ’S) for sheet metal parts ?
Due to our specialty in short run orders, we are very flexible in order quantities. Our quotes always to respect customer’s requirement.
What I should do if I don't have a PDF file or print?
If you don't have a PDF file or print , you can provide/send a tangible prototype, then come by our facility or send us the prototype and we will be more than happy to discuss your product.
What is considered a normal lead time?
This depends upon the complexity of the project, but in most cases you should allow for 3 to 4 weeks to complete your parts.
What is the difference between a medium and large run?
In general, a medium run of parts would be in the vicinity of 100-500 parts per order. Anything more than 1,000 would be considered a large run.
