As representatives of a multimillion-dollar industry, it’s hard to admit it, but plastic injection molding services face endless challenges every day to avoid mistakes on their production runs. Quality issues are often some of the most frequent causes of a failed product, as you can imagine this can bring big-time loses to our clients if we don’t handle prep work properly.

Poor engineering also plays a big role, especially if a client plays hardball when it comes to expecting their products delivered following certain specs that are just not realistically achievable by any means. Putting the finger on each of these issues is meaningless if both parties are not able to reach a compromise that doesn’t affect the finished product.

In the next few lines will list some of the most common issues affecting plastic injection molding services and what causes them. This might give you some understanding of how our procedures work and why time, above everything else, it’s crucial to make everything work out for the best. Let’s take a look:

· Blistering

Blistering it’s probably one of the most common issues happening on any production run around the world. You can notice it when a layered space on the surface of the products rises above everything else. The main cause of blistering is when the mold doesn’t have the proper time to cool down or when the cooling system is not working properly. Both causes are usually attached to tight schedules on the client’s end, but it can also happen due to poor maintenance of the equipment handling the molding procedure.

· Burning Marks

A burning mark is a dark stain appearing on the finished product, usually where a gap or air gets trapped inside the mold. Burning happens because the mold it’s not properly vented or because the injection speeds are way too fast. These problems can be easily avoided with time adjustments and a revision of the casting mold.

· Burrs

A burr happens when excessive polymers are poured into the mold making a section of the finished product look thicker on one side, thus making it unbalanced and looking deformed. The issue also happens due to speedy injection processes, but it can also be caused due to faulty programming on the clamping procedure or by the mere presence of contamination in the tooling spaces.

· Degradation

Degradation is what happens when the polymers used to break down and the product delivered is of poor quality. It happens when excessive water it’s used in the cooling process, or when the temperatures of the casting mold are way too high to work with the materials provided. It can also happen due to excessive regrinding on the manufacturer’s end.

All these causes can be tracked to both ends. If the client asks for low-end materials while disregarding the recommendations of the manufacturer, this will surely happen. However, if the company working on the project tries to pull a fast one by using mixtures of materials to save costs, this will happen too, and it will be noticeable when the client begins to sell faulty products.
