Project Submission Requirements

Slide background

QUALITY METAL FABRICATION AND CERTIFIED WELDING.

Each part being submitted for quotation or fabrication should conform to the requirements on this page.

Please note:    Parts will be fabricated to specifications contained on fabrication drawings, but in most instances are programmed from solid model files provided by the customer.  Customers are responsible for providing us with accurate fabrication drawings and solid part files.  Wilkins Design and Manufacturing does not accept responsibility for inaccurate or inconsistent data provided by the customer.  Parts created from inaccurate solid model data or flat pattern files that was supplied by the customer will be billed to the customer.

Request For Quotation:

All requests for quotation should be accompanied by a fabrication drawing of the part that is in the electronic form of a Portable Document Format (PDF) file.   Providing a solid model in Initial Graphics Interchange Specification (IGES), STEP-file or PARASOLID file is encouraged.  Files, along with other information can be emailed to Service@Wilkinsmfg.com.

Placing Orders:

It is important that we receive appropriate and accurate information along with electronic files for each part that is ordered.  Orders that do not conform to our requirements may be subject to delays beyond the delivery time quoted and additional costs relating to programming.   Files, along with other information can be emailed to Service@Wilkinsmfg.com.

Electronic file types:

All orders should be accompanied by a fabrication drawing of the part that is in electronic form of a Portable Document Format (PDF), as well a solid model of the part in an appropriate file type.

Appropriate File Types and Configuration:

CNC milled or turned parts solid model should be provided in Initial Graphics Interchange Specification (IGES), STEP-file or PARASOLID file.  Models should be in wireframe configuration.

Sheet Metal Parts:

Files for both a flat pattern and solid model should be provided.  Solid models can be provided in Solidworks part file format (SLDPRT), IGES, STEP-file, or PARASOLID file type that is a wireframe configuration.  All solid model parts should be created with bend radii that meet our air die bending capabilities, as described below.  Generally, all parts will be formed using air dies.  Coining of bends can still be done, but is considered an exception and done only in special circumstances.  K-factor settings may need to be adjusted by us or the customer, but a good starting point is to enter a factor of .415.  Flat patterns should be submitted that conform to our bend capabilities in either a Drawing Exchange Format (DXF) or IGES file.

Air-die Bending Capabilities:

Gauge              Min. Inside Bend Radius        Max. Bend Length

26-20                  .039 in.                                       10 ft

18 to 16              .066 in.                                       10 ft.

14                        .105                                             8 ft

12, 11, 10           .157                                             8 ft

3/16 – ¼             .328                                             8 ft

Parts designed with bend radii that do not conform to the foregoing requirement may be rejected and returned to the customer to have fabrication drawings and solid models revised or may be subject to additional programming charges.  Special bends will be evaluated for capability and cost.

Please contact us for part and file requirements for any parts that are to be formed with coining or special form tooling.
