The Quickparts Injection Molding Process: From Prototype to Production

01

Initial meeting with injection molding experts

Every project starts with a conversation. Our team takes time to understand your part design, performance goals, and production needs before making any recommendations. That early alignment helps avoid surprises and sets the foundation for a smooth process.

02

Robust manufacturing analysis

Once we receive your design files, we run a full manufacturability review. That includes checking tolerances, material suitability, and moldability to catch potential issues before tooling begins. You’ll get clear feedback on what works, what might need adjusting, and why.

03

Complete program review

Before any production starts, we meet with you to review the full scope of the project. That includes the quote, lead times, technical specs, and any special requirements. You’ll know exactly what to expect to plan all your other business decisions.

04

First Article Inspection and quality review

Before the full production run begins, we produce a first article for inspection and validation. Our quality team reviews the part against your specifications, including dimensional accuracy, cosmetic standards, and functional requirements. If adjustments are needed, we make them early so the final run meets or beats expectations.

05

Production and delivery

Once approved, we move into production with your dedicated team managing every step. You’ll get updates on progress, timelines, and any key milestones as your parts move through the line. Shipping is coordinated to meet your delivery window, with full visibility along the way.

06

A complete partnership

Quickparts supports your product far beyond the first run. If you need design revisions, want to scale to higher volumes, or are exploring new materials, we stay involved and ready to help. Think of us as an extension of your team.

Injection Molding FAQs

What is plastic injection molding?

Plastic injection molding is a process used to make large numbers of identical plastic parts. It works by injecting melted plastic into a custom-shaped mold, then cooling it until it hardens into the final shape. It’s commonly used for everything from medical components to car parts to consumer products.

How does plastic injection molding work?

First, a custom mold is created based on your part design. Then plastic pellets are melted, injected into the mold under pressure, and cooled until the part solidifies. Once the mold opens, the finished part is ejected and the process can repeat quickly for high-volume production.

What is the injection molding cycle?

The injection molding cycle refers to one full run of the process from closing the mold and injecting plastic, to cooling, opening the mold, and ejecting the part. Each cycle typically takes seconds to minutes depending on part size, material, and tooling. Fast cycles are what make injection molding ideal for producing thousands or even millions of consistent parts.

What are some injection molding design challenges to avoid?

Common molding design challenges include walls that are too thick or thin, sharp corners that can cause stress points, and parts that are hard to remove from the mold. It’s also important to consider how the plastic will flow through the mold to avoid defects like warping or sink marks.

That’s why Quickparts runs a design-for-manufacturing review with every client to catch these problems before you commit to tooling.

Where does Quickparts offer injection molding services?

Quickparts provides injection molding services across North America with fully owned manufacturing facilities that support fast turnaround and close collaboration for local projects. Internationally, we support customers across Europe with production sites in Italy, France, and the UK.

With global in-house production facilities and a network of vetted partners, we’re able to offer reliable, consistent service in multiple markets.
