Plastic is relevant to our businesses and to our daily lives. If you take a simple look around you you will most likely come across an item that is made of plastic. That item had to go through a manufacturing process to get its shape. It is ideal for businesses that want to pack their own products and manufacturing them to gain more knowledge on the different types of plastic manufacturing methods.
The manufacturing industry is gigantic and it is consistently growing as consumer demands expand. Manufacturing plastic, though, is a way businesses can mass produce their products in a simple and fast way. Not only does molding plastic open more doors for inventions and new ideas but it makes way for those who want to create a product of value.
Compression molding
Compression molding is the process that places heated plastic into a mold that is also heated and closing it to compress the plastic to a specific form or shape. It is then cooled and removed from the mold to reveal the finished product. A compression molding machine is usually used to complete the process of creating a range of applications, from automotive parts to body armor.
Compression molding is meant for high-strength materials like fiberglass and strengthened plastic. The goal of this manufacturing method is to create products that are stronger, sturdier, and resilient against wear and tear. This isn’t like other forms of plastic molding as it creates more durable products.
Extrusion molding
Various methods of manufacturing and
Extrusion molding machine works in a rather simple way. First, the plastic resin is fed into the feeder with a turning screw. Then the melted plastic is moved through the die to create the tube that is then cooled down and removed. The die helps the molten plastic move through the tube easily and gives it the needed shape. This is the best method for creating pipes, straws, and other long hollow applications. You have the capability of creating different shapes as well.
Heat staking
Heat staking is a plastic manufacturing method that involves using both hot air and hot stamp methods. It is a simple concept that combines two or more components for materials together. Usually at least one material is made of thermoplastic. A Heat staking machine, or hot riveting machine, uses heat and pressure to reform the plastic to various shapes and forms to join the two materials together. Pressure doesn’t release until the product has cooled to ensure that the parts are fixated properly.
Heat staking is commonly used for various low-cost applications like medical tools, IT and consumer appliance, and automotive parts. This method is the most efficient way to bond metal and plastic together successfully.
Injection molding
Injection molding is actually one of the most popular ways to mold plastic. It is commonly used in making daily items like:
- toys,
- household tools,
- phone accessories,
- Bottles
- and more.
The process is simple enough that an employee isn’t required to have much involvement.
An injection molding machine is ideal for those who need to manufacture large quantities at a time. The machine is designed to handle large volumes of work and comes in various sizes ranging from 5 tons to 6000 tons. This method is so versatile that it can create just about anything from large auto parts to smaller parts. There is plenty of room for customization due to the fact that various types of resin can be used during this process. Engineers can create complex or unusual products or simple devices meant for consumers.
Blow molding
Blow molding is exactly what it is called. This plastic molding method involves the same basic steps to glass blowing. This process combines both blowing mechanisms with heat so that the plastic can change shape through air pressure. The heated plastic is blown into the shape of a tube where the parison inflates the plastic until it fits the designated mold. This is a popular method for creating bottles or container style products.
You don’t get the smaller-scaled machine size like you would a heat staking machine due to the fact that there is space provided for a larger production. This method is used for manufacturing hollow items in large volumes because the machine can create thin-walled containers quickly which is great for forming small bottles and large storage containers.
