6 TOP ADVANTAGES OF PLASTIC INJECTION MOLDING

Manufacturers prefer plastic injection molding to other forms of plastic molding due to its versatility when creating different plastic parts and products. Plastic injection molding is particularly handy during the mass production of plastic parts or toys. This method is not only simple and reliable but also quite efficient.

To better understand why plastic injection molding is the go-to solution for manufacturing various plastic parts, here is a dive into 6 of its major advantages.

1. Efficiency

The plastic injection molding process is quite fast and produces a greater quantity of molds in a very short time than most other processes, which makes it a cost-effective and efficient method. The result is an increase in revenue and profit margins for the manufacturer.

Unlike the traditional methods, plastic injection molding allows for the mass production of parts and components without compromising quality.

2. Accuracy

Plastic injection molding is a highly accurate process that produces detailed and complex parts without any deviation. Since the process subjects injection molds to extremely high pressure, manufacturers can easily include many intricate details into the design of the plastic part or component.

Plastic injection molding allows for the design and manufacture of complex plastic parts that other conventional molding methods can't achieve. However, the manufacturer must uphold fundamental design elements to produce the desired results. Talk to your plastic manufacturer to learn about their design restrictions.

Despite any restrictions, since the injection molding process is fully automated, even the most complex designs are relatively inexpensive to manufacture.

3. Strength

Plastic has evolved, with sturdy plastic now featuring in rugged applications on par with their metal counterparts. Unlike the conventional process, you can use fillers in plastic injection molding. The fillers comprise strength-imparting materials such as calcium carbonate, mica, silica, glass, alumina trihydrate, clay, etc.

The fillers make the plastic less dense during the molding process and add strength to the plastic part after the process. Industries such as the auto industry require small plastic parts that need to be sturdy and durable, which is now possible thanks to plastic injection molding.

4. Eco-Friendliness

Manufacturers must take into account the environmental impact of their operations. Since plastic is a non-biodegradable material, any way to reduce plastic waste is highly welcome. Fortunately, plastic injection molding uses just the right amount of plastic needed to produce parts. This process, therefore, produces less waste than the conventional molding methods.

Manufacturers recycle the little plastic waste generated during the molding process using modern machinery, which significantly reduces the environmental impact of the injection molding process.

5. Labor

The automation of the plastic injection molding process greatly lowers manufacturing costs. The process costs less in labor, with only one operator required to control the machines and robotics. Less labor means a low cost of manufacturing plastic parts and, ultimately, a low-end product price.

Also, because plastic injection molding can produce more molds in less time than other processes can, the process is cost-effective.

6. Cost

The low-cost factor of the injection process goes beyond reducing labor costs. Since the process utilizes computer-aided designs (CAD) and computer-aided manufacturing (CAM), highly accurate injection molds are created the first time. You incur no further costs recreating those parts.

The lack of inaccuracies and high production output adds to the cost efficiency of the plastic injection molding process. While the initial mold creation can be costly, the cost reduces in the long run because you can produce a large volume of plastic parts using the initial mold. This feature makes plastic injection molding more affordable than traditional machines.
