TechnicalDrawings

Technical Drawings are my specialty.  That is what I went to college for.  My Degree is in "Mechanical Drafting Technology"....aka creating technical drawings.  I have been creating technical drawings since I was in high school and know my way around them.  Sure, 3D Models are great, but for manufacturing, drawings are still king.  Drawings will communicate the size, shape, layout, color, material and overall specifications of your parts.  The drawing also serves as a legal document for when parts are not manufactured "to specification".

Technical drawings can consist of drawings for:

Depending on the type of part drawing needed from above will determine how the drawing will look.  Drawings will contain information that is pertinent to that application.  Drawings will contain up-to-date title blocks populated with titles, dates, materials, company information, descriptions, etc..  They will adhere to the latest drafting standards according to ASME; or follow your company's standards.  I can create new drawings or use legacy data from your old CAD programs files.  There usually is not a part that I cannot model and create drawings for.

Machined Parts

Machined Part drawings which are probably the most popular of drawings needed.  Machining drawings will contain all proper dimensions, notes, tolerances, and anything else needed to properly machine the part.  I try to be consistent in Datum references to minimize confusion and make the part easier to make.

Casting Prints

Cast Part drawings or Casting Prints are another popular type of print.  Casting Prints will communicate to a metal caster as to how a part needs to be cast using molten metal.  Casting prints differ in machine prints as there are certain industry specific standards that need to apply.  Castings for instance need to have draft angles; meaning that all sides that are perpendicular to the mold face need to be angled inward to allow for the part to be released from the mold.  Also most castings do not have sharp corners on its edges as molten metal does not flow well around corners.  Casting prints also have instructions for how injection pins are to be placed and used.

Forging Prints

Forged Parts drawings or Forging Prints are very similar to casting prints, however, the process for forged parts is what differs.  Draft angles and rounded edges are still needed.  Forged parts are are made using solid billets or ingots and then put under extreme pressure.  Forged parts are much stronger than cast parts due to the tighter grain structure of the metal.

Injection Molding Prints

Injection Molding Prints are a piece of work in themselves.  They differ so much from other types of parts because they have so many requirements.  Injection Molded parts tell a molder how a part is to be molded out of plastic.  Injection Molded drawings have to have the following requirements:

  • Draft angles

  • Parting line location

  • Ejection Pin sizes and locations

  • minimum wall thickness

There are strict guidelines as to how molded parts are to be designed to ensure proper strength and structural integrity of the part once molded.  Let me hook you up today with some properly drawn molding prints!

Assembly Prints

I pride myself in all of my prints, but assembly prints are my pride and joy---I love making these type of drawings.  Assembly prints relay to assemblers how a product is to be assembled.  They usually consist of an exploded view, bill of materials (parts list), cut list, section views, and any relevant information to make an assembly easy to put together.  Assembly Prints usually do not contain dimensions unless they are critical.

Assembly Instruction Manuals

I can create stunning, easy to follow manuals for your product as well.  These can be created in any custom size that you want and provide any information that you see fit to allow the end consumer to assembly your product.

Shop Drawings

In a previous job, I worked for a granite company creating shop drawings for application of granite to buildings and homes.  This is where I honed my skill for creating complete shop drawings.  I do not focus on these much anymore as most of my clients are mechanical, but I still do them!  I can generate all views that you need such as plan, elevations, section vies, detail vies, etc...
