What are Advantages of Using Plastic Injection Molding for the Manufacturing of Parts?

Plastic injection molding toolmaking is extremely versatile method of producing standard parts and products. It is one of the preferred methods for manufacturing parts in large scale because it has multiple advantages over other methods of plastic molding. Not only is plastic injection molding simpler and more reliable, it is also extremely efficient. You should have no doubts about using this method to manufacture parts.

Here are 5 major advantages of using injection molding for manufacturing plastic parts and components.

1. Detailed Features and Complex Geometry

The China precision plastic injection mold are subjected to extremely high pressure. As a result the plastic within the molds is pressed harder against the mold compared to any other molding process. Due to this excessively high pressure, it is possible to add a large amount of details into the design of the part.

Furthermore, due to high pressure during the molding process, complex and intricate shapes can easily be designed and manufactured which otherwise would have been too complicated and expensive to manufacture.

2. High Efficiency

Once the plastic injection molds have been designed to the customer's specifications and the presses pre-programmed, the actual molding process is very quick compared to other methods of molding. Plastic injection molding process hardly takes times and this allows more parts to be manufactured from a single mold. The high production output rate makes plastic injection molding more cost effective and efficient.

3. Enhanced Strength

In plastic injection molding, it is possible to use fillers in the injection molds. These filler reduce the density of the plastic while it being molded and also help in adding greater strength to the part after it has been molded. In fields where parts need to be strong and durable, plastic injection has an option that other molding processes do not offer.

4. Ability to Use Multiple Plastic Types Simultaneously 

One of the major advantages of using plastic injection molding for manufacturing parts is the ability to use different types of plastic simultaneously. This can be done with the help of co-injection molding, which takes away the worry about using a specific type of plastic.

5. Automation to Save Manufacturing Costs

Plastic injection molding is an automated process. A majority of the injection molding process is performed by machines and robotics which a sole operator can control and manage. Automation helps to reduce manufacturing costs, as the overheads are significantly reduced. Furthermore, with reduced labor force the overall cost of manufacturing the parts is reduced and this cost saving can easily be passed on to the customer. Furthermore, automation allows for making precise and accurate injection molds. Computer aided design (CAD) and computer aided manufacturing (CAM) allow close tolerances during the making of the molds.

Above are the main advantages of plastic injection molding process, there are still other features not mentioned.
