See why our customers love us

Every quarter, we order approximately 20 sets of plastic enclosures for our device from 3ERP. The enclosures were initially made by urethane casting, but Ronan came back to me with the idea of using an aluminum mold, which allowed me to get a few hundred moldings. We decided to move to this process. The T1 samples weren’t good enough, as we got some shrink marks, but this was quickly sorted out when we received the T2 samples.

Although we had to invest more for the mold, we now save 70% compared with urethane casting, and we can use UV-resistant ABS to keep the color stable. Overall, I am very happy with the solution.

Two months ago, I was super stressed by an urgent plastic molding project. Our customer desperately wanted 100 sets at very short notice in order to run testing with real materials, even though normal production would have taken more than six months. None of our preferred moldmaking suppliers could help us, given the deadline. Luckily, one of my friends recommended 3ERP to us by chance.

3ERP has a fantastic mold design team. They managed to finish the mold design within 10 days and started to fabricate the molds right after that. I was surprised that more than 60 items, including some big parts, were completed to a decent standard within two months. Our customers eventually received the moldings to run their testing. 3ERP saved our business!

What is Rapid Tooling

Rapid tooling, sometimes known as prototype tooling or bridge tooling, is a fast and cost-efficient way to carry out low-volume injection molding for a variety of types of plastic parts. Once the aluminum or steel mold has been created with the rapid tooling process, it can be utilized as part of a molding process to create multiple copies of a part. Rapid tooling is therefore used to create moldings for rapid prototyping needs in a shortened timeframe, or to bridge the gap before high-volume production.

The rapid tooling process involves the creation of a mold using aluminum or soft steel, a stocked mold base, and hand-load inserts. Rapid tooling is one of the best methods for fulfilling small batch orders meant for use in marketing samples, product evaluations, and process design.

Traditional tooling is often prohibitively expensive for small projects. Our custom rapid tooling service is a cost-effective, low-volume alternative in situations where large volumes of the part won’t be needed in the future. The rapid production tooling process is commonly used in industrial settings for prototyping solutions or for diagnosing design issues, providing an easy introduction to mold making.

At 3ERP, we typically create rapid molds by CNC machining and EDM, though we also sometimes use additive methods such as 3D printing technologies.

Rapid Tooling Materials

Aluminum Mold Tooling

Aluminum Mold Tooling

An ideal choice for prototyping, aluminum mold tooling provides a cost-effective way to produce molded parts. Since they are easy to cut, aluminum molds can reduce tooling costs by 15–25% compared to other mold materials and reduce cycle times by up to 40%. This translates to a faster turnaround for our customers.

Aluminum evenly dissipates heat, which provides dimensional stability in tooling. This significantly reduces deformation and produces less waste during the production process. It is important to note that aluminum is not as strong as steel, so it has a shorter life cycle and is less useful in high-volume processes.

Steel Mold Tooling

Steel Mold Tooling

Steel is a sturdy, solid, high-quality tooling material, though it is not suitable for all applications. Steel molds have a longer life cycle than aluminum and are therefore ideal for high-volume production. Steel can also be used to produce molds from engineering-grade plastics that are resistant to abrasion and corrosion.

Though it features multiple benefits, steel is a more expensive tooling material than aluminum and requires more turnaround time to produce molds and prototypes.

Benefits of Rapid Tooling

Fast processing
Fast processing

Prototype tooling provides quick results, so the transition between development and production is very short.

Economy of Scale
Economy of Scale

Economy of Scale In most cases, rapid tooling is the most cost-effective option for an order of 100–2,000 units: too many for 3D printing, CNC machining, or urethane casting, but not enough to justify mass production tooling.

Material Options
Material Options

Material Options Whatever material is available for injection molding can also be molded by rapid tooling. A wide range of material options is, therefore, one of the core benefits of the process.

Customizable Finishing
Customizable Finishing

With rapid injection molding, we can tailor molds to produce different finishes including smooth, glossy, and textured. Further finishing procedures such as painting, chroming, and silk-screening can then be applied to the moldings.

Proof of concept/testing
Proof of concept/testing

Rapid prototyping facilitates practical real-world design testing and troubleshooting solutions. It also enables quick and precise production of new tooling that implements design changes and improvements.

Speed to market

Rapid Tooling & Mold Making Projects

Rapid Tooling for Tail Light Project

Rapid Tooling for Tail Light Project

Can you imagine attempting to make prototype tools for over 30 components in just two months? Our customer desperately needed 200-300 sets of tail lights for testing, but mass production tools wouldn’t have been ready for eight months. They needed a solution to get good quality moldings by their deadline and at a much lower cost than production tools. 

For this tail light project, we needed to fabricate a housing, reflector, light guide, bezel, an outer lens, and other components in a short period of time. The overall assembly size was about 600 x 400 x 150 mm, which is relatively large and the customer wanted to test real materials. In this case, 3D printing, CNC machining, and vacuum casting were not suitable, so prototype molding was the only option. Click to view this case

Rapid Tooling FAQ

Why should I use rapid tooling?

Rapid tooling is a fast and cost-efficient way to create a few prototypes in a selected material for function and aspect testing, as well as for low-volume manufacturing to test out the market.

How fast can I get the moldings?

This depends on the size and geometry of the parts. For a common open and shut mold with regular size part such as 300 x 300 x 50 mm, fabrication of tools and moldings can be done within 10 days.

What materials can I choose from with rapid tooling?

There is no limit to material choice. Any plastics available for mass production, including common silicone and rubber materials, can also be used with the rapid tooling process.

What is the quality level of rapid tooling?

Moldings from rapid tooling are end-use-parts quality. They are very close to mass production parts.

How many moldings can I get from rapid tooling?

Normally, aluminum molds are good enough for +/- 1,000 shots, while Steel P20 molds can last for +/- 10,000 shots.
