How much time does product engineering take?

Not every product design is immediately suitable for injection molding. When you approach us, it's certainly not necessary to have already made the design injection-molding ready.

That’s why we like to be involved from the very first idea, so we can think along with you. In doing so, we consider technical feasibility, the available budget, and material selection. This process depends entirely on various factors, which can differ from project to project. As a result, it's difficult to estimate the time in advance — it can range from a few weeks to, in some cases, up to a year.

How much time does the entire process from idea to product take?
"
The time varies greatly depending on the complexity of the project, optimizations, and guidance during the product design and engineering phase, prototyping, and production. On average, the process can take anywhere from a few weeks to several months. Read more about the entire process from idea to product on our injection molding process page!

Injection Molding or 3D Printing?
"
The choice between plastic injection molding and 3D printing as a production method depends on the desired material properties, production volume, and lead time. Injection molding is a good option for larger volumes, while 3D printing offers flexibility for small batches and prototyping.

What are common design mistakes in injection molding?
"
Common design mistakes in injection molding often occur when manufacturability is not properly considered during the design phase.
One of the most common issues is non-uniform wall thickness. This leads to uneven cooling and shrinkage, which can cause warping or sink marks. Maintaining a consistent wall thickness is essential for a stable and high-quality part.
Another mistake is the use of sharp corners. These create stress concentrations and increase the risk of cracks or failure. Adding proper radii improves both strength and material flow.
Draft angles are also often overlooked. Without sufficient draft, parts can be difficult or impossible to eject from the mold, which can result in damage or production issues.
A common misconception is that a design is always technically feasible just because it looks correct on a drawing. In reality, not every design is suitable for injection molding without adjustments.
In short, good design for injection molding requires uniform wall thickness, rounded corners, sufficient draft angles, and a strong focus on manufacturability from the start.
