5 Injection Molding Mistakes That Can Kill a New Product

Taking a product from idea → prototype → mass production is exciting—but in injection molding, small decisions early on can create big costs later.

Here are 5 common mistakes we see in new product development:

1️⃣ Ignoring DFM in the early stage

Designs that look good on screen may be impossible—or very expensive—to mold.

2️⃣ Inconsistent or excessive wall thickness

This often leads to sink marks, warpage, longer cycle times, and higher part costs.

3️⃣ Choosing material based on price only

A cheaper resin can result in poor strength, surface defects, or long-term failures.

4️⃣ Underestimating mold structure & tooling quality

Poor gate design, venting, or cooling layout directly impacts part quality and production stability.

5️⃣ No plan for scale-up

A design that works for prototypes may fail when moving to tens or hundreds of thousands of units.

💡 The key takeaway:

Injection molding success is not just about making parts—it’s about engineering the product for manufacturability from day one.

If you’re developing a new plastic product and want to avoid costly rework, early collaboration with an experienced molding partner makes all the difference.
