Polymer injection molding involves injecting moltenplastic to create a desired shape throughcooling. The continuous process allows companies to create identicalplastic
parts in high volume at a lower price. Various industries apply this process and formula to mold different shapes of plastics.
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.
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, severalpolymer injection moldingcycles 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 tinyparts ineach large mold.
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.
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.
