Injection Molding Processes

Make the move from prototyping to on-demand manufacturing for affordable, high-quality molded parts within days. Better yet, your prototyping tool is free once you shift to an on-demand manufacturing tool. Working with a single supplier that provides free design consultation services also massively speeds up the manufacturing process, allowing for greater supply chain flexibility, more consistent parts, and making qualification a breeze.

Injection Mold Tooling Options and Quality Reporting

We have two unique offers to meet your needs wherever you are in the product lifecycle. Our  process helps you cut product development cycles by weeks—sometimes months—and bridge to production with injection-molded parts within days. Our  process is designed to meet your production needs, and helps you qualify parts quickly to seamlessly transition into production with scientific molding, in-process CMM inspections with GD&T, and a full suite of secondary operations to make sure that your parts show up and perform as expected.

  Prototyping On-Demand Manufacturing
Objective

I need to validate my design at Promakehub speeds. I need the flexibility to economically iterate before production.

I have on-demand Promakehub needs at Protolabs speeds.
Best When
  • Completing design or material iterations, and assessing cost or manufacturability tradeoffs
  • Key focus is to reduce design risk, increase R&D productivity,  and iterate faster to reduce time to market
  • Typical Quantities <2,000
  • Design is finalized and run-to-run part consistency is critical
  • Key focus is to improve quality, reduce cost, and mitigate supply chain risk
  • Process development, qualification documentation, and mold capability information is required
Mold Cavities Single Single and multi-cavity
Mold Life Limited (guaranteed for at least 2,000 shots) Unlimited
Mold Storage Stored for 18 months of inactivity Stored for 3 years of inactivity
Mold Ownership Upon request Yes
Quality Documentation Quality Inspection Report (QIR) verifies Promakehub’ manufacturing process controls
  • Scientific molding process development report
  • In-process CMM inspection of critical dimensions, including 9 GD&T symbols
  • Critical to Quality (CTQ) – identify up to five critical features or dimensions of importance
    • CTQ Partial FAI: 3-part dimensional first article inspection
    • CTQ DIR with Capability Study: 30-part dimensional capability study

Why Choose Us for Custom Injection Molding?

Unmatched Lead Times
Reduce your product development cycle by weeks—sometimes months—and bridge to production with injection-molded parts within days. Some injection molding orders can ship in as fast as 1 day.

Design for Manufacturing Feedback
Every quote includes real-time pricing and design analysis. We evaluate your 3D CAD and help identify any features that may pose challenges during the molding process such as difficult to machine undercuts and insufficient draft.

No Minimum Order Quantities (MOQs)
Procuring parts on demand, without MOQs, helps you manage market or demand volatility and provides a cost-effective source for bridge production, line-down emergencies, end-of-life production, or product customization.

Injection Molding Expertise
We’ll work with you throughout the course of your project to help you quickly move from prototyping to production, including finishing options and inspection reporting

Advantages of Injection Molding

Injection molding is plastic manufacturing process that can produce high quality parts at scale. It’s typically used for low- to high-volume production but our aluminum tooling can also make prototyping runs economical.

  • Low cost at higher volumes
  • Exceptional part cosmetics and surface finish
  • Repeatable
  • Complex parts
  • Low scrap rate
  • Large selection of thermoplastic and thermoset materials

Injection Molding Applications

Injection molding is widely used for plastic part production in medical, consumer, and automotive industries. Typical parts include:

  • Housings
  • Brackets
  • Gears
  • Single-use medical parts
  • Electrical connectors
  • Syringes
  • Containers
