Did you know that plastic injection molding is one of the most commonly used processes in production?
Plastic injection molded parts are used in various industries, but they are especially prevalent in the automotive industry. That’s because parts are incredibly strong and durable. Used to making dashboards and other car parts, which proves their strength.
They are often stronger than metal parts. But what is the reason for their durability? If you want to find out, you’ll want to keep reading. Here’s everything you need to know about the strength of plastic injection molded parts.
Types of Plastic Used in Injection Molding
The most common types of plastic used in injection molding are polyethylene terephthalate (PET), polypropylene (PP), acrylonitrile butadiene styrene (ABS), and polycarbonate (PC). Each type of plastic has unique properties that make it more or less suitable for use in a particular application.
PET is one of the most widely used plastics in the world. It is strong and lightweight, making it ideal for various applications, from food packaging to medical devices.
However, PET is not well suited for high-temperature environments due to its low melting point. Another common type of plastic used in injection molding is PP. It is similar to PET in terms of its strength and lightweight properties.
However, PP has a higher melting point than PET, making it a better choice for high-temperature environments. Due to its high impact resistance and durability, ABS is an engineering plastic frequently used in the automotive industry. PC, clear plastic, is used within applications where transparency is required, such as in medical devices or safety goggles.
What is the Tensile Strength?
The tensile strength of a material is the maximum amount of stress it can withstand before it breaks. The tensile strength of plastic injection molding is typically between 3,500 and 10,000 psi. This is significantly higher than metals’ tensile strength, typically between 1,000 and 4,000 psi.
In addition to being robust, plastic injection molded parts are also very durable. They resist chemicals and environmental factors like humidity and temperature changes. This makes them ideal for use in various industries, including the automotive industry.
What Are the Benefits?
There are many benefits to using plastic injection molded parts. In addition to being solid and durable, they are also lightweight. This makes it possible to reduce shipping costs when transporting them.
They are also inexpensive to produce, which helps to keep costs down for consumers. They are an excellent way to make custom parts. Plastic injection molded parts are a great way to save money and increase efficiency.
