Metal Fabrication is the heart of old 91

Old 91 was created as part of a manufacturing company and grew to hold it’s own. Spray Force International was created in 1968 and Old 91 Steel is the metal fabrication arm.

Because we were created as a part of a manufacturing company – we understand all the moving parts and how they effects everything that you want to do.

Metal fabrication is our foundation but we also enjoy helping companies to make better manufacturing decisions.  Tell us how we can help your company grow.

Professional engineering and technical services

There is no one accepted model of the engineering design process.

Each model varies in complexity from 3 step loops to very complicated interwoven steps that are made to monitor the overall progress towards a completed and ready for production product.

The three step loop contains the elements ideate, implement, test.

More complete systems have the steps: establishment of objectives and criteria, synthesis, analysis, construction…(click the learn more for the full article)

Press Brake and Bending Services

A press brake is a tool to bend sheet and plate materials.  

Two C-frames form the sides of the press brake along with a table at the bottom and a movable beam at the top.

The tool has two pieces one mounted on the table, and the other tool mounted on the upper beam.

Press Brakes are typically defined by their force, tonnage and maximum…(click learn more for the full article)

Mig, Tig, and Stick welding Services

There is no one-size-fits-all option for welding services.

Your results are highly dependent on applying the right welding process to the task at hand.

For example if you use a high-powered method or the highest settings on your machine you run the risk of melting the surface you need welded, ruining your work.

Or if you need to weld a large area, choos…(click learn more to read the full article)

Paint and Coating Services

 Plastic coatings accommodate a number of sizes and shapes, the most common plastic coating is Teflon.

Paint was a short-term solution in the past, as it would often flake and fall off the surface of metals.

Now high heat paint, like the paint used on…(click learn more to read the entire article)

Metal Rolling and Shaping

Deforming a workpiece through mechanical deformation, and changing the shape of the piece without altering its mass is the process of metal shaping.

It can be done by hand with a form, or an object that has the shape of the finished piece, and a hammer.

The most common form is a…(click learn more to read the entire article)

Laser Cutting

Laser cutting uses a focused laser to cut materials and is commonly used industrially with sheet metal parts and products.

It can also be used to cut diamond, glass, silicon, wood, and plastics.

Older laser cutting machines used mirrors, but modern machines increasingly use…(click learn more to read the entire article)

CNC Services

Using a computer to aid in transforming a stock piece of material to a finished product is CNC.

CNC stands for computer numerical control, and started in the 1940’s and 50’s using punched tape or perforated paper tape.

It quickly transitioned to analog and then digital mediums, and now uses CAM or CAD files to give the instructions for the finished…(click learn more to see the whole article)

Milling Services

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece.

It requires a milling machine, workpiece, fixture, and cutter.

The workpiece is a pre-formed block of material that the milling process will turn into the finished…(click learn more to see the whole article)

Lathe and Turning Services

 The first major innovations in lathes happened in 1751 when Jacques de Vaucanson invented a all-metal slide lathe, and when mechanized power was available to drive the shaft of the lathe and allow for faster, more accurate work.  

In the 1950’s CNC or computerized numerical control was added to lathe machines to allow for even more…(click learn more to see the full article)

Metal Cutting

 Cutting is the collection of processes where material is formed into a desired shape by removing excess material.

This uses various tools and results in two products, the waste or excess material and the finished part.

There are three major categories;  chip producing processes…(click learn more to see the full article)
