What is innovation? No, seriously…

Engineers in the medical space are solving complex problems and a company calling itself “innovative” doesn’t matter to them in the slightest. While working on a new project FA last week, the OEM team wanted to test challenging resins for a mold we knew likely wouldn’t work. We surprised them, and even ourselves. The new…

Molding glass optical components into larger structures at high temperature

After a webinar, I was asked by an engineer if a micro molder is able to mold, or overmold, glass optical components into a larger structure, simultaneously, withstanding wide temperature ranges. The temperature range this engineer specified ranged from -40° to 105° Celsius. In the wide majority of cases, this answer is a crystal clear…

Understanding micro molded part inspection.

Creating a precision microscopic component is an achievement, but measuring to ensure its accuracy is an achievement in itself. This is why so many engineers want to know the process behind micro mold part inspection. How are micro mold parts inspected? Micro mold parts are inspected automatically or by hand. There are three main categories of inspection in the…

What is the lead time for micro molding?

It’s a question we get quite a bit from OEMs and engineers, what is the lead time for micro molding? Generally speaking, the lead time for micro mold tooling is 4-7 weeks, but depending on the project, the time frame can change. Factors that determine micro mold lead time Depending on internal work load, our…

Micro Molding: The toolroom perspective & DfMM

There is a world of difference between how a product looks on a computer screen and reality. At the beginning of the design stage of product development, it is vital to give due consideration to the scale of micro molded part — especially the scale of some of its internal features. Put simply: parts may…

Micro flaws can be a big deal: the DfMM process

Standard deviation exists in every single project. The two by fours framing out your new kitchen all vary in length to a small degree. It is minuscule (hopefully) but it is present. The same is true in manufacturing. Producing the highest quality part requires understanding any potential flaws that could affect their application, major or…

High-Flow Resin Challenges For Injection Molding

When designing a new device, component, or complex injection-molded part, world-class OEM engineers and rookies alike come to the same choke point when selecting the perfect micro mold material. Your instinct may be to opt for a familiar or even high-flow resin but dealing with microscopic tolerances completely re-writes material selection.  Every OEM designer and…

As parts go micro, gate placement becomes a challenge.

Scott Byal As technology miniaturizes, traditional design engineering aspects of injection molded parts are now causing problems. When looking at the micro mold gate, where polymer enters the mold cavity, only a small percentage of part geometry and surface area is affected. In micro molding however, the gate becomes a part feature. This poses problems…
