1. Detailed features and complex geometry

The injection mold is subjected to extremely high pressures. Therefore, the plastic in the mold exerts more pressure on the mold than other molding processes. Due to the excessive pressure, a large amount of detail can be added to the design of the part.

In addition, due to the high pressure during the forming process, complex and    intricate shapes can be easily designed and manufactured, otherwise it would be too complicated and expensive to manufacture.

  1. High efficiency

Once the injection mold is designed to the customer’s requirements and is pre-programmed, the actual molding process is very fast compared to other molding methods. The plastic injection molding process takes almost no time, which allows more parts to be manufactured from one mold. High production efficiency makes injection molding more cost effective and efficient. Typically, the hot runner exits the mold system to produce parts that are more consistent in quality and faster in cycle times, but it is not easy to change color, and the hot runners cannot accommodate some thermosensitive polymers. Learn more about the key differences between hot runners and cold runner systems.

  1. Enhance strength

In injection molding, a filler can be used in an injection mold. These fillers reduce the density of the plastic during molding and also help to increase the strength after molding. In areas where parts need to be rugged, injection molding has options that are not available in other molding processes.

  1. Ability to use multiple plastics at the same time

One of the main advantages of using plastic injection molding to make parts is the ability to use different types of plastics simultaneously. This can be done with the help of co-injection, which eliminates the concern of using certain types of plastics.

  1. Automation to save manufacturing costs

Plastic injection molding is an automated process. Most injection molding processes are performed by machines and robots, and only one operator can control and manage them. Automation helps reduce manufacturing costs because management costs are greatly reduced. In addition, as the labor force decreases, the total cost of manufacturing parts is reduced, and this cost savings can be easily passed on to customers.

In addition, automation can produce accurate and accurate injection molds. Computer-aided design (CAD) and computer-aided manufacturing (CAM) allow close tolerances in the mold manufacturing process.

6.    Bottom line

Injection molding also ensures that the produced parts require little work after production. This is because after the parts are ejected from the injection mold, there is more or less the appearance of the finished product.

Today, plastic injection molding is an environmentally friendly process. The waste plastics produced during the production process must be reground and reused. Therefore, this process produces very little waste.
