Small part injection molding is an efficient and economical manufacturing method used across many different industries and product categories.

When compared to traditional casting methods or 3D printing, plastic injection molding is quicker to set up and easier to scale. Furthermore, the injection molding process is highly automatable, making it ideal for today’s domestic customers in search of a more flexible and reliable supply chain solution.

You’ve designed your part, created the tooling, and are ready to begin the plastic injection molding process. But then, there is a change of plans. Rather than using ABS plastic, you will now be making the parts out of nylon. No problem. Just have some nylon shipped to the manufacturer and you’re good to go, right?

Plastic Injection Molding Gate Blush: Causes and Prevention

[fa icon="calendar'] Sep 19, 2017 9:48:00 AM / by Jon Gelston posted in Plastic Gate Design, Plastic Injection Molding Defects

[fa icon="comment"] 4 Comments

What’s known in the plastic injection molding business as “gate blush” or simply “blush” is a cloudy or hazy discoloration of the plastic on a finished part. It is most often found near gate locations, where material enters the part. Not only is the defect in color and gloss visually unappealing, the plastic in that area can be weaker than in the rest of the part. Needless to say, it’s an issue that needs to be corrected as soon as it is discovered.

In plastic injection molding, the “gate” is the opening in a mold through which the molten plastic is forced into the cavity, the tooling representation of your part. The type of gate (which I’ve blogged about previously) and its location are critical. In fact, it’s no exaggeration to say that gate location can make or break a part. The type and placement of the gate can affect many aspects of a project including:

Plastic Injection Molding: Gate Basics

In plastic injection molding, one of the most important aspects of the mold design is how and where it is gated. The “gate” is the opening in a mold through which the molten plastic is injected into the final part.  It is the boundary between part and scrap. The location, size, and shape of the gate can have a significant effect on everything from the structural integrity to the visual appearance of a finished piece.
