Have you ever picked up an injection molded part and seen what appear to be faint lines in the part, or maybe they were cracks? Most likely they were just knit lines caused by the molding process. If you’re unfamiliar with what causes them, and ways to avoid them, we’ll dive into the subject of…
When you start on a new project, and more specifically are looking for a new injection molding partner, your design team will need to understand how large of a machine will be required to make your new product. The calculation to determine the right press tonnage size isn’t complicated, but it does require a few…
If you’ve ever picked up an injection molded part, you can find a line around the circumference of the part. Why is it there, and how is it created as the part is molded? It’s a simple answer, but it can be quite complicated to explain. Let us give it a try… What is the…
Time is money in the global economy. Finding every way to save investment money and reduce project time is one way to stay ahead in business. There are many ways to reduce costs, and often the lure of sending your business overseas to China looks very tempting. If you’ve thought of sending your injection molding…
Starting on a new project is always an exciting time. One of the earliest discussions with your design and manufacturing teams needs to be on the cavities required for the injection molds. Which is going to be the best for your new project? Choosing between one or the other isn’t a decision that should be…
When discussing topics within the realm of Material Science, invariably the term ‘strength’ always comes up. How strong is a material? How does it compare to another material? Strength can be subjective as it has many different properties within the term. Tensile strength and compressive strength are two areas that are discussed with plastic injection…
Plastic injection molding is one of the frequently chosen manufacturing methods for new products. With thousands of resins available today, and more being created every year, it’s no mistake that injection molding should be a consideration for your next new or updated product idea. The plastic resin typically gets all the credit, but there is…
Several critical elements must be considered while manufacturing a high-quality molded part, including part design, fabrication, material selection, and production. Designing elements based on practical requirements is vital while preserving the design objective or end-use. Before all of the components get finally documented and sent to a molder for production, the injection-molded product design goes…
Plastics are everywhere. In your home, your automobile, and definitely in your electronics. Plastics are used in almost every industry around the world due to their low investment cost, environmental advantages, and their durability. The electrical industry uses many different plastics to keep you safe, provide durable solutions to transmit power, and often times house…
There are many steps on the road to producing a plastic injection molded part. Most would think the biggest step of the process would be the execution of the design. The ability to make a quality part true to the design intent isn’t solely reliant on the production end. The engineering can dictate if the…
