Why choose Senturi for Rapid Tooling?

Prototype and Short-Run Injection Moldings
Exact plastic material as final design

  • Molding quantity started from 100 pieces
  • Much lower cost than production mold
  • Fast delivery 

Fast Mold Making

Machined aluminum or soft steel mold cavities is the key to get injection molds done fast for low-volume moldings. Simplify the mold design, use stock mold components & mold bases is extra acceleration.

Rapid Injection Molding

Besides of regular production molding, we have over 10 injection molding machines ready for prototype or small quantities molding. The molds will be loaded to the machines right away without delay.

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


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 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.
