Injection Moulding Applications & Products

The Quickparts Injection Moulding Process

01

Initial meeting with injection moulding experts

It all starts with a conversation. We take the time to understand your part design, performance targets, and project goals before offering any guidance. That early alignment helps us shape the right solution and keeps your production process on track from the beginning.

02

Robust manufacturing analysis

Once we’ve received your CAD files, our engineers run a detailed manufacturability review. This includes checking dimensions, tolerances, materials, and mouldability to flag any potential issues. We’ll walk you through what’s working, what may need adjusting, and how to avoid setbacks later on.

03

Complete program review

Before production kicks off, we bring everything together for a full program review. That includes your quote, technical drawings, timeline, and any specific quality or regulatory requirements. This keeps the whole team aligned, and you’re able to move forward with full confidence.

04

First Article Inspection and quality review

Next, we produce an initial part for your approval. This first article undergoes a detailed inspection to confirm dimensional accuracy, part finish, and overall performance. If any tweaks are needed, we handle them quickly so the final production run meets your standards.

05

Production and delivery

Once we move into production, you’ll receive regular updates on tooling progress, run schedules, and shipping timelines. Delivery is coordinated to match your deadlines, with full visibility at each step.

06

A complete partnership

Quickparts supports you beyond the first order. If you need design iterations, larger production runs, or new material options, we’ll stay close to your project. Consider us a long-term extension of your team who cares just as much about your projects as you do.

Injection moulding FAQs

What is the injection moulding cycle?

The injection moulding cycle refers to the full process of creating a part in a mould. It starts with clamping the mould shut, then injecting molten plastic into the cavity. Once the plastic cools and solidifies, the mould opens and the part is ejected. Each cycle can take just seconds for small parts, or longer for more complex moulds.

What plastics are used in injection moulding?

Many thermoplastics can be used, depending on the part’s requirements. Common materials include ABS, polycarbonate, polypropylene, nylon, and polyethylene. Each plastic has different properties like strength, flexibility, or heat resistance, so we’ll help you choose the one that best fits your application.

Is injection moulding environmentally friendly?

It can be. Injection moulding produces very little waste per part since excess plastic can often be recycled or reground. Plus, once the mould is made, producing each part uses minimal energy. Using durable moulds and recyclable materials makes the process more sustainable over time.

How much does injection moulding cost?

Costs vary based on part complexity, material choice, and volume. The initial tooling (mould) is typically the largest upfront expense, but once that’s made, the cost per part is low, especially for higher volumes. We give every partner a detailed quote that breaks down tooling, material, and production costs.

What are the differences between prototype and production moulds?

Prototype moulds are typically made from softer, less expensive materials like aluminium and are designed for short runs, like testing part designs before full production. Production moulds use hardened steel, last much longer, and support high-volume output with tighter tolerances. Both help get your product to market, just at different stages of development.

How long does it take to produce injection moulding tools?

Lead times depend on part complexity and the type of mould. Quick-turn prototype tooling can be ready in as little as one week, while production-grade tools typically take 4–8 weeks after design approval.

What is the maximum part size for injection moulding?

At Quickparts, we can mould parts up to 1500 x 1000 x 350 mm depending on your project and tooling requirements. If your part pushes the size limit, we’ll advise on best-fit tooling or alternative approaches to meet your specs without compromising quality.
