Rapid Tooling

STAMOD can support in Rapid Tooling which is a process that is the combination of Rapid Prototyping techniques with conventional tooling practices to produce a mould in less time or parts of a functional model from CAD data in less time and at a lower cost relative to traditional machining methods. Rapid Tooling can act as a bridge to production injection molded parts.

 

Rapid Tooling is distinguished from conventional tooling in that:

  • Tooling time is much less than for a conventional tool.
  • Tool life is considerably less than for a conventional tool.
  • Tolerances are wider than for a conventional tool.

Advantages to rapid tooling is, it lowers the time and cost of the product. Rapid tooling is used for specific need such as prototyping and trouble shooting existing problems.

Rapid Prototyping is not often used for large scale and operations of a part for long term. Nevertheless, since the time lag is so short between start to finish and only CAD file is needed for the design stage rapid tooling have started to be used to create moulds for commercial operations.

Rapid Prototyping allows companies to quickly make commercial products with the advancement of rapid prototyping reason being the alternate methods require precious time and resources, Rapid tooling provide moulds for the required products in less time.

RT also provides customization necessary for personal applications. RP processes allow scientists and doctors the ability to scan and digitize the item or patient instead of trial and error then by putting it through a CAD program, a personal custom mold can be created to fix the problem.

 

In Rapid Tooling there are two categories:

  • Soft Tooling.
  • Bridge Tooling.

Soft Tooling is made out of Silicon Rubber Resin and is called Soft Tooling due to its flexibility(also called Silicon Rubber Mould). Silicon Rubber Mould is used to produce plastic prototype components (out of Polyurethane Resin) and in some cases wax patterns for further Investment Casting.

Bridge Tooling is intermediate between Soft Tooling and Hard Tooling, both on count of strength and production. Here the die is produced by spraying low melting alloys over the RP Master and by providing back up materials like Epoxy Resin around it. In comparison to Soft Tooling, this is a longer process and more durable, which can with stand limited injection pressure. Dies produced through this route die can be used for production of components of commercial plastics and wax patterns for investment casting. This process may also be used for prototype sheet metal forming.
