The Quickparts Injection Molding Process: From Prototype to Production

01

Initial meeting with injection molding experts

Every project starts with a conversation about your part design, production goals, and performance requirements. Our team helps define the best approach before tooling begins.

02

Robust manufacturing analysis

We review your design files for manufacturability, tolerances, material selection, and moldability to help identify potential production issues early.

03

Complete program review

Before production starts, we review project scope, lead times, technical requirements, and tooling details so expectations stay aligned from the start.

04

First Article Inspection and Quality Review

Our quality team inspects the first article against your specifications to verify dimensional accuracy, appearance, and functional performance before full production.

05

Production and delivery

Once approved, we move into production with dedicated project oversight, production updates, and coordinated delivery scheduling throughout the process.

06

A complete partnership

Quickparts supports ongoing design revisions, production scaling, and material adjustments long after the initial production run is complete.

Materials

Quickparts offers most commercially available thermoplastics, each with its own performance characteristics. We help you choose the right material based on factors like strength, flexibility, temperature resistance, and cosmetic appearance so your parts meet all functional requirements.

Common materials include:

  • Acrylonitrile Butadiene Styrene (ABS)
  • High-Density Polyethylene (HDPE)
  • Low-Density Polyethylene (LDPE)
  • Polycarbonate/ABS blend (PC/ABS)
  • Polyethylene Terephthalate (PET)
  • Polymethyl Methacrylate / Acrylic (PMMA)
  • Polyoxymethylene / Acetal (POM)
  • Polycarbonate (PC)
  • Polypropylene (PP)
  • Polystyrene (PS)
  • Nylon 66 (PA 66)
  • Glass-Filled Nylon 66 (PA 66 GF)
  • Polyether Ether Ketone (PEEK)
  • Polyetherimide / ULTEM™ (PEI)
  • Thermoplastic Elastomer (TPE)
  • Thermoplastic Polyurethane (TPU)

Finishes

Quickparts supports all standard production-grade surface finishes to match the look and performance your parts require. Options include polishing, texturing, and matte or gloss finishes, depending on your material and mold design. If you’re unsure which finish you need, we’ll guide you to the right option for your application.

What is Plastic Injection Molding?

CNC milling services in Italy

Plastic injection molding is a manufacturing process that produces high volumes of consistent plastic parts by injecting molten material into a custom mold. The process supports complex geometries, tight tolerances, and repeatable production across automotive, medical, industrial, consumer, and other high-performance applications.

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.
