Material selection checklist for plastic injection molding

The right choice of material determines whether your plastic product will really do what it’s supposed to do – technically, aesthetically, and in terms of cost. With this Material Selection Checklist, you get an at-a-glance overview of the most important points to make well-founded choices and prevent surprises in the injection molding phase.

What will you find in this checklist?

Strength, stiffness, impact resistance, temperature, chemical exposure, environment – conveniently listed together.

✅ Overview of commonly used plastics
With typical applications, pros and cons, and when you’d be better off not choosing a material.

✅ Pitfalls from practice
Such as underestimated shrinkage, wall thicknesses that are too thin, or materials chosen incorrectly for series production.

✅ Sustainability options listed
Bio-based, recyclate, energy-efficient production, and what this means for design and cost price.

✅ Checkpoints for consultation with your supplier
So you enter the conversation with the right questions and expectations.

Who is this checklist for?

✅ Product engineers and product managers in manufacturing
✅ R&D teams developing a new plastic product
✅ Technical directors who want to control risks and costs

Are you working on a new product or optimizing existing parts? Then this checklist will help you get to a manufacturable, scalable, and affordable design faster.
