Which is Better: Plastic Injection Molding or Die Casting?
This is a very good question to start with. Before we can start to formulate our own conclusions, let’s go ahead and find out what plastic injection molding and die casting is first. These are the difference between mould and die.
What is Injection Molding?
It is considered to be one of the most popular manufacturing processes today. It is widely used by custom belt buckle manufacturers. Depending on what is needed, raw materials can be made of metal, glass, confections, or elastomers. But the most popular raw material is plastic.
How Are Products Made with Injection Molding?
First, design and plans must be finalized. After everything is ready, raw material like duraflex material will be melted in a big barrel. After melting, it is injected into a mold that is usually made of strong metal. After taking the shape of the mold, it is allowed to cool and ejected from the machine. These are the injection moulding process parameters.
Some products manufactured under this method are automotive parts, toys, kitchen utensils, combs, bottles, appliances, educational supplies, strap buckles, and a whole lot more.
This manufacturing process has a lot of advantages. First, it is very cost effective because little or no waste is produced. Second, it is very eco-friendly due to the first reason. And third, it produces high quality products. With all of this in mind, can you even imagine a life without injection molded plastic?
What is Die Casting?
Now that you are already familiar with injection molding, it will be easy for you to understand what die casting is. Unlike injection molding, die casting only engineers various metal parts or products made of metal.
How Are Products Made with Die Casting?
The process is also similar to injection molding. Raw materials made of metal is melted under extreme but exact temperature, forced into durable steel molds and allowed to cool before taken off the machines.
Are you a toy car collector? Your toys probably are made through the die cast system. Steel pipes, car parts, electronics, golf equipment, and faucets are just some of the products made through it as well.
The Die Casting Advantages
It has numerous advantages. First, the system can be done in an automatic fashion. Second, the molds can be used over and over again due to its durability. Third, the products made through this are more durable and has a longer service life. And fourth, it is economical too!
So Which is Better?
There may be a difference between mould and pattern in casting but the answer totally depends on what you need. If you need products that are very durable and can withstand extreme temperature and has magnificent electrical properties, die casting should be your choice but if you need plastic products with highly complex designs but are durable for everyday life, then injection molding maybe it.
You may also consider the types of moulding available for each system before you can finally choose the right one for you.
