Top 3 Challenges Facing Injection Moulding Businesses—And How to Fix Them

by

Injection moulding companies face daily frustrations that often stem from one core issue: a disconnect between design and manufacturing. When product designs aren’t created with real-world production in mind, the result is costly delays, rework, and disappointed customers.

In an industry where margins are tight and expectations high, here are the three biggest challenges that hold manufacturers back—and what you can do about them.

1. Poor Collaboration Between Design and Production Teams

One of the biggest obstacles is the lack of effective communication between designers and manufacturing teams. CAD files are often passed along with minimal context or collaboration, leading to confusion, delays, and costly errors on the shop floor.

With global supply chains and remote working now the norm, relying on email attachments or outdated file sharing only worsens the problem. Every misstep costs time, resources, and ultimately, trust.

Solution: A design-for-manufacture (DFM) process that involves production teams early—ensuring everyone is aligned before tooling begins.

2. Designs That Aren’t Fit for Manufacture

Looks aren’t everything. A CAD design may seem perfect—but if it ignores the realities of injection moulding, it can be expensive to fix. Common issues include missing draft angles, unworkable tolerances, or poor material flow—all of which can lead to tooling failures and production delays.

Solution: Designs should be created with tooling in mind from the start. At Convert Design, we use Siemens NX and combine engineering expertise with real toolmaking experience to produce CAD models that are production-ready.

3. Compromising on Quality for Speed or Style

When deadlines are tight or aesthetics are prioritised over performance, quality can suffer. Quick fixes might get a product out the door, but they often lead to costly warranty issues, rejected batches, or unhappy end users.

Solution: Balancing form and function is possible—with the right design partner. One who understands that good design supports both appearance and manufacturability.

In today’s world, if you’re serious about creating, inventing, or improving a product, you can’t avoid one crucial step: 3D design. Whether you’re developing a new product or refining an existing one, the first question any manufacturer will ask is: Do you have a 2D drawing or a 3D model? This is especially true for plastic injection moulding, where accuracy and manufacturability are everything.
