At its inception, rapid tooling was the ability to generate core and cavity inserts as a product of a rapid prototyping technology. Rapid tooling was the result of an additive process driven by 3-D CAD – a process that requires little or no machining or EDMing. For some, rapid tooling continues to be described in this narrow scope.

Others, however, have embraced a description of rapid tooling that has expanded to a much broader scope. Perhaps the most important factor to this change was the use of the adjective “rapid.” Since the opposite of rapid is slow, a company that cannot claim to be a rapid tooler could be perceived as a “slow” tooler. A secondary driver is the attractiveness of the phrase “rapid tooling.” Inclusion of “rapid tooling” in advertising and literature attracts the attention of buyers and results in sales. Rapid tooling has become a loosely defined buzzword.

The resulting broad definition of rapid tooling has evolved to describe any method that delivers tools in substantially less time than would be expected from a historical perspective. Loosely, this translates to the delivery of a prototype tool and sample shots in three to six weeks.

Rapid Tooling – Narrow Definition
“New process delivers inserts in two weeks!” is a frequent statement in trade journals. What the provider of the advertised rapid tooling process does not state is that a two-week delivery is based on ideal circumstances such as no backlog, ideal part size, ideal part geometry and reasonable molding parameters.

When the requirements and the component’s definition match the capabilities of the rapid tooling technology, magic can happen. Leadtimes can be slashed. There are powerful rapid tooling solutions available today. Of the dozens of processes, each one can claim numerous success stories where their clients have dramatically reduced price and time. Rapid tooling is a powerful solution when it is selected as the right tool for the job.

However, today’s rapid tooling solutions are generally niche applications. They excel when all conditions are right and the buyer can accept the limitations of the process in order to gain a time advantage. It is this narrow breadth of application that prevents these technologies from becoming widely used and generally known.

In the near future, major advances will take place, and these advances will enable rapid tooling technologies to take hold and become standard methods in the product development and production process. With this knowledge, leading companies may not choose to employ a rapid tooling solution today, but they will keep abreast of the technologies to take advantage of the developments when the time is right.

Rapid Tooling – Broad Definition
Any company that cannot claim to be a rapid tooler, in the broad definition, must have a clear and deliberate strategic focus. Cutting time out of the process to meet and exceed customers’ delivery demands is, and will continue to be, a major force in the moldmaking industry.

Just 10 years ago, a typical leadtime for cut aluminum tooling would be six to 12 weeks. Today, these leadtimes are typically four to six weeks. In the next few years, it is foreseen that leadtimes for aluminum tools could fall to two to four weeks. With this increasing speed of delivery, these traditional methods must be considered to be rapid tooling solutions.

Technology plays a role in gaining an advantage through reduced leadtimes. The growing use of 3-D CAD systems combined with efficient CAM packages makes programming faster. The ability to transmit CAD data electronically over the Internet streamlines the process. Advances in machine tools and the growing use of high-speed machining, reduce the time required to cut the tool. These technologies enable moldmakers to respond quickly. Incorporating these advances is vital to long-term success. However, technology enables time reduction, but it does not guarantee it.

Advanced technology without the people and processes to make it efficient and quick, is of no benefit. Before or in conjunction with the addition of leading-edge technologies, a successful company will work on its business and production flow. If high-speed machining is available, but the backlog in polishing is extreme, the only result is creating more work in progress faster. Without overall efficiency, the buyer may not see a reduction in the delivery time and will not consider the service to be rapid.

In today’s market, the rapid tooling label can be applied to any company that has highly efficient processes, people and work flow. Being faster than the competition allows a company to rightfully claim to be a provider of rapid tooling solutions. Employing the narrowly defined rapid tooling and the latest moldmaking technologies is not a requirement, it is merely an enabler. The buyer does not care how the job gets done. They are concerned only with receiving their order quickly with the prescribed quality and value.
