Plastic Injection Molding: Definitions and Benefits of Using It 

To earn more money from the manufacturing industry, we have to know the main basics of advanced technology about molding and, more specifically – plastic injection molding. Most of the manufacturers are very interested in this technology to use an incredibly effective way to produce sophisticated plastic parts and components.


In fact, to create our daily essential plastic tools and components with accuracy, the plastic injection molding process is valuable for increasing production and saving your production time with a lot of profit.


But, what’s the plastic injection molding technology actually, and why should we consider this process in our plastic manufacturing industries?


Let’s sort it out.


About Plastic Injection Molding Process


Plastic Injection Molding is a well-known production process for creating expensive plastic tools and components on a large scale. It is basically considered for mass- manufacturing processes where similar products are made millions of times accurately.


The injection molding process cuts the original plastic in a considerable percentage with fewer scrap rates like CNC precision machining – the traditional manufacturing process. Firstly, with the help of 3D printing technology, the simplified injection molding production process creates some sample plastic parts heating plastics by a specific mold. These molds are also designed into the customers’ desire with maximum flexibility and finished sample products.


Until finished the certain perfect sample design, the process has to continue with the help of different metals and glasses. And, after ending this process, it is ready to go in the plastic injection molding process machine to make even millions of duplicates. It is a highly useful & effective injection molding method for customizing injection molded tools and components.


History Of Plastic Injection Molding


The history of Plastic injection molding started in 1868 with the hand of John W. Hyatt, who patented celluloid replacing ivory in billiard balls. And, after four years, he became fully successful inventor injecting heated celluloid into a mold.


After then, with the help of his brother Isaiah, he started to design the first plastic injection molding machine. That machine was a manual usually used plunger for injecting hot liquid plastic into the mold for certain shapes. Buttons and hair combs were the early injected molded products in around 1782.

In the mid-20th century, the emergency of the plastic injection molding process raised a huge necessity for inexpensive plastic products. A revolutionary change came to the manufacturing plastic industries due to the mass production of different types of plastic tools and components.


Let’s discuss how the plastic injection molding is beneficial for the plastic manufacturing industries.


Why Should We Prefer Plastic Injection Molding Machines for Manufacturing Plastic Tools?


Efficiently Faster Production: 


Like CNC Precision Machining, Plastic Injection Molding is itself faster than other processes. It is now considered as the most popular efficient type of molding with a speedy manufacturing output rate. It can produce thousands of tools per hour with perfect size and quality.


According to The Rodon Group, a plastic injection molding machine is able to run 24 hours, 7 days by creating an MRP (Material Requirement Planning)system. It needs a short time to complete all the cycles of components with a huge quantity of similar tools.


Thus, this process must help you to manufacture plastic parts within a little cost because of working with the fewest workforce to raise the profit levels.


Accurate Features:


According to Statista, statistics show that the demand for injection molding plastics in the U.S.A will rise approximately 11.5 million tons within 2025.


So, it is true that there is a great demand for sophisticated and accurate plastic tools and components in the market. And customers desire to get excellent flexible plastic products, but for a manufacturer, it is a very much complex process to create a perfect sample within a short time.


Therefore, if you can make and approve the sample to the customer, your plastic injection molding machine is ready to take the challenge for production accurately with extreme pressure for a long time.


Furthermore, because of having computerized technology, it is very easy to design and manufacture sophisticated and accurate shaped plastic tools during the injection molding process. For other traditional, methods it would be too difficult and expensive for producing plastic components.


Perfect Product Strength Enhancement:


Strength is the main factor for the plastic tools that must be considered designing and manufacturing in the plastic injection molding process. In this manufacturing process, some fillers are used for decreasing the density of the plastic in the time of the molding process, and after molding, also add sufficient strength to the plastic components.


We have to be more conscious about the product’s durability and flexibility so that the customers can fix the components at a specific position. 


Decreasing Manufacturing Costs:


If you want to earn more profit, of course, you have to reduce product manufacturing costs. Obviously, it is possible only in the plastic injection molding process for being an automated process. Most of the injection molding processes operate with computerized machines that the only person can control the manufacturing process.


As a result, the fewest man powers need to run the whole plastic injection molding process. That is why the manufacturing cost comes to the lowest level and creates an opportunity for the highest profit.


Furthermore, software-based automated technology allows for producing tools and perfect injection molds. The CAD ( Computer-Aided Design) and CAM ( Computer-Aided Manufacturing) consider fewer tolerances for creating the molds.


Fewer Waste Materials:


Plastic tools manufacturers need to set up eco-friendly production initiatives for massive injection molding productions. That is why you have to ensure minimal material waste and plastic recycling processes during the injection molding process.


As the tools are made with an injection-molded process with a high volume, there are fewer options in the plastic injection molding process to produce waste materials because of the opportunity to use it again and again. As a result, this ability will help you to reduce cost-efficiency and save money with high rate automatic output.


Using Different Types of Plastic


Instead of using a particular type of plastic, the plastic injection molding process can spontaneously use multiple types of plastic material. Because of having a co-injection molding system, there is nothing to be worried about pressing certain types of plastic.


Choosing Right Color


Selecting the right form of color is an important part of the tools and components of a project. Even, there are almost an endless variety of colors for different plastic parts in the plastic injection molding process. 


So, ensuring the right resin color approved by FDA, ROHS, REACH, and NSF is also necessary for injection molding manufacturers with the highest consideration.


Final Words


If you invest in a proper work field and take the patient, the wild money must come. For the first time, it might be a little expensive, creating a perfect mold. Because of cost reduction up to 25 times less than ordinary plastic industries for lower manpower costs with high rate output volume, you will get a lot of money at the end of the delivery.


That is why, at present, the environment-friendly plastic injection molding process is very much popular with the plastic tools manufacturers.
