When most engineers and product designers think of ABS (Acrylonitrile Butadiene Styrene), they picture a tough, reliable, and cost-effective engineering plastic. It's the go-to material for automotive interior parts, household appliance housings, keyboard keycaps, and countless other durable goods. But ABS has one consistent limitation: it's opaque.

Enter MABS (Methyl Methacrylate Acrylonitrile Butadiene Styrene) – commonly known as transparent ABS. At first glance, it shares the same tough genes as its cousin, but it adds a critical dimension: optical clarity.

In this post, we'll break down the science behind their differences, compare their performance side-by-side, and explore when you should choose one over the other. Read More

When molding thick-wall polycarbonate (PC) parts, two of the most common—and frustrating—defects often appear together:





Sink marks on the surface



Burn marks or short shots caused by trapped air

Many process technicians instinctively try to solve both by tweaking the same parameter. That’s where things go wrong.

The truth is: sink marks and venting issues stem from different stages of the injection cycle and require separate, targeted adjustments. In this post, I’ll walk through a practical strategy to tackle both without falling into the trap of overcomplicating your process setup. Read More

When it comes to injection molding, size changes everything. The design principles that work perfectly for small consumer parts often fail spectacularly when you scale up to large structural components like automotive bumpers, television housings, or industrial pallets.

So, what is the fundamental shift? For small parts, strength is the priority. For large parts, stiffness—resistance to elastic deformation—takes precedence. The mold must not bend or deflect under the enormous clamping forces, or you will lose dimensional accuracy and dramatically shorten mold life.

But designing the mold is only half the battle. For many large parts, even the best traditional molding process struggles with warp, sink marks, and excessive weight. That is where Gas-Assisted Injection Molding (GAIM) comes into play.

Let us break down the critical considerations for manufacturing large injection-molded parts, with a deep dive into gas-assist technology. Read More
