Formioo Injection Molding Service FAQs

We collect a lot of FAQs from our real clients, and please check out our FAQ page. For more information about Formioo Company, you can also download our company E-catalogue brochure.

What is the minimum order quantity for injection molding?

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

Can you provide a no-obligations estimate for my injection molding project?

Absolutely. As long as you can provide project requirements and part specifications, Formioo is happy to offer a no-obligation quotation.

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

Of course! Formioo will maintain your mold for 2 years after your most recent order, allowing you to reorder parts throughout the mold’s life.

Does Formioo charge an inventory fee on my molds?

No, Formioo doesn’t charge inventory fees for molds as long as they’re used within 2 years. After 2 years of inactivity, we’ll ship or destroy the mold as per your instructions.

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

Yes, we do! You can access your DFM and 3D visualizations on the Formioo platform, comment, annotate, and discuss with a technical project lead before placing your order.

Does Formioo charge for DFM feedback?

At Formioo, we believe in delivering the best possible parts on the first try. That’s why we provide DFM feedback at no cost, ensuring you have all the information you need before placing your injection molding order.

What DFM analyses does Formioo provide?

Injection molding may be involved, and we help our customers keep it simple. We offer draft, thickness, and sink analysis with every quotation. Advanced DFM services, such as parting line visualization, side action analysis, and mold-flow analysis, are available upon request.

How long does it take to make molded parts?

Once the material and mold are prepared, the injection molding process can produce several hundred molded parts in a day, depending on the needs of production and part complexity. Initial configuration to set the molds and get the material may require a couple of days, but once the production is in progress, it can be quite efficient with regular throughput. For mass production runs, schedules will vary based on part size, features, and finishing or post-process steps required. Formioo works with you to provide precise schedules and meet deadlines.
