Polymer injection molding involves injecting molten plastic to create a desired shape through cooling. The continuous process allows companies to create identical plastic parts in high volume at a lower price. Various industries apply this process and formula to mold different shapes of plastics. Since the process does not work well with every project, you must understand the pros and cons of the system. The following are some advantages of polymer injection molding and why you, as a manufacturer, should turn to injection molding.
Provides Complex Geometries with Tight Tolerances.
Polymer injection molding can produce large volumes of uniform products and complex parts. As a manufacturer, you must focus on the vent and gate placements, the weld lines, the thickness of the walls, and the major designs. All the mentioned emphasized factors help ease ejection and achieve a precise part.
The Process Can Be Used with A Wide Range of Materials and Colors.
There are more than twenty-five thousand engineered materials compatible with polymer injection molding, for instance, thermoplastics, thermosets, silicones, and resins. It means that the available options will give you a chance to choose the one that has the right balance in terms of physical, mechanical, and chemical properties. At the same time, polymer injection molding also provides a variety of options where you can decide on the colors you want to work with according to your desire and tastes.
It Is Efficient Compared to Other Methods.
On most occasions, it takes several minutes or hours when you want to 3D print or CNC machine a single part. However, several polymer injection molding cycles take 10 to 60 seconds. There are instances when you have complex geometry that can take around 120 seconds to mold. Still, you can incorporate various tiny parts in each large mold. This will help you maximize efficiency and get the most out of every mold. In turn, it will allow you to create several identical parts per hour at a given low cost.
Enhanced Strength
When it comes to polymer injection molding gives a chance to use fillers in the injection molds. The fillers can lower the density of the plastic during the molding process. At the same time, it helps in adding greater strength to the part after the molding process. When operating in areas where parts are required to be strong and long-lasting, polymer injection molding is the best option.
Saves Manufacturing Costs.
Polymer injection molding is an automated process that helps reduce the cost of manufacturing, because the overheads are reduced significantly. On top of that, reducing the labor force will help lower the entire manufacturing cost of the parts, and the cost saving will then be passed to the customers.
In general, polymer injection molding is a process that ensures that the manufactured parts do not need any further work after production. The reason is that after the production, the parts will have either more or less finished appearances after the ejection from the injection molds. The reality is that polymer injection molding has a lot to offer to you as a manufacturer.
