Curious to know about the materials and processes that are best for high-volume medical cart production? There are many cost-saving opportunities for high-volume production runs, and this article will cover with the pros and cons associated with each option.

Stamping

High-Volume Production

Pros:

• Stamping is a cost-effective option and great for high volumes.
• The shaping process is quick. It only takes one hit to form it.

Cons:

• High tooling costs.
• You have to trim the material hanging over the sides after you stamp.
  
  

Aluminum Extrusions

High-Volume Production

Pros:

• Aluminum extrusions are great for medium to high production runs.
• Good surface finish.
• For the most part, there are no limits on the shape of the design.
• Tooling is very cost-effective, even for larger parts.
• It’s a good substitute or replacement for sheet metal components.

Cons:

• The parts may require secondary machining.
  
  

Castings

High-Volume Production

Die-Castings: Best finishing and you need to run very high volumes (millions of parts).

Permanent Mold Castings: Need to run high volumes.

Sand Castings: Need to run medium to high volumes.

Pros:

• Castings are great for high volumes because the process is very repeatable.
• Undercuts are not a problem with di-castings.
• For the most part, there are no limits on the shape of the design.

Cons:

• Tooling is expensive.
• Undercuts are a problem with sand and permanent mold castings.
• Castings often require a secondary process to add finishing, threads, and any machining processes, because they don’t have in-mold inserts.

Injection Molding

High-Volume Production

Pros:

• Injection molding is cost-effective for high production runs.
• You can add color, texture, threaded inserts, and undercuts in the mold.
• You can run large quantities with one tool.
• Companies can use recycled materials to create the tool.
• They can also make parts out of recycled materials, if the part’s color does not matter.

Cons:

• Tooling is expensive.
• Long lead times on tooling.
• Any changes can be costly, because you will have to change the tool.
