Injection Molding FAQs

Is injection molding a good option for prototyping?

Injection molding could absolutely be used for prototyping, but it depends on the project requirements. Typically, for projects that require less than 10 prototypes, injection molding may not be the most cost-effective option. We are happy to meet with you to discuss your needs and help determine if injection molding is the correct process for you.

What is the minimum order quantity for injection molding?

Arapidtools is happy to offer you injection molding services with NO minimum order quantity.

Does Arapidtools provide a no-obligations estimate for my injection molding project?

Absolutely. As long as you are able to supply project requirements and part specifications, Arapidtools is happy to provide a no-obligation quotation.

Once I have a mold, can I reorder from it?

Of course! Fictiv will maintain your mold for 3 years after your most recent order and allow you to re-order parts for the duration of the mold life.

Does Arapidtools charge an inventory fee on my molds?

Arapidtools does not charge any inventory fees for holding your molds, as long as you order off of the mold within 3 years. After 3 years of inactivity, Fictiv will ship/destroy the mold at the customer’s direction.

Does Arapidtools provide DFM on my part design before I place an order?

We do! Not only are you able to access your DFM through the Fictiv platform, but you will receive 3D visualization of the DFM feedback and be able to comment on, annotate, and discuss this feedback with a Fictiv technical project lead. All of this happens before you place your order.

Does Arapidtools charge for DFM feedback?

We believe in getting our customers the best possible parts the first time. Therefore, Arapidtools does not charge for DFM and we ensure that you have all of the assurances you need before you place your injection molding order.

Does Arapidtools build quick turn Aluminum molds?

Arapidtools has the ability to build both aluminum and steel molds.

At what quantity is it worth it for me to move from 3D printing my parts to injection molding them?

A part manufactured through 3D printing is orders of magnitude more expensive than the same part manufactured through injection molding, assuming the design is a fit for injection molding. As long as you produce enough of that part to offset the mold cost, it would be worth it to pursue injection molding. Arapidtools provides you with DFM on your design and options for mold architecture to give you the best cost-benefit balance. Request an injection molding quote for your 3D-printed part design to get a no-obligation quotation and DFM and assess your options at no cost to you. It is recommended that you get an expert involved early on in the design process if you intend to use injection molding for production. Many customers invest significant time in creating 3D-printed prototypes and making revisions without taking into account the specific manufacturing constraints associated with injection molding. This oversight can lead to wasted resources, both in terms of money and time. By providing Design for Manufacturability (DFM) guidance tailored to injection molding, Arapidtools can help you avoid such pitfalls, resulting in significant savings in time and costs.

What DFM analyses does Arapidtools provide?

Injection molding is a tricky process, and one that we want to work through with our customers. This means that while we offer draft, thickness, and sink analysis on-platform for every quotation, we often provide advanced DFM in the forms of parting line visualization, side action analysis, and mold-flow analysis upon request.

Does Arapidtools perform mold flow analysis before building the molds?

Arapidtools does not conduct mold flow analysis as a standard DFM analysis for injection molding, however, it can be done as an additional service upon request.

How long will it take to make injection molding tooling?

The tooling lead time can vary depending on the complexity of the part. In some cases, it can be as quick as 10 days, while in a more complex design, it may extend to around 21 days (calendar days). For parts larger than 300mm, the lead time might be further extended due to the additional complexities involved in manufacturing larger components.

How long does it take to make molded parts?

Once the materials and molds are prepared and in place, the injection molding process allows for the production of several hundreds of molded parts per day.

How does Arapidtools protect my intellectual property?

At Arapidtools, we know how critical information security is, especially when working with high-value design IP. That’s why we designed our platform with elite-level security and confidentiality as a top priority. From log in to file upload to part fulfillment, you can rest easy knowing that your IP is safe within our secure Digital Manufacturing Ecosystem. Read More about it here.
