If you want to understand the process of injection molding then you must contact a plastic mold manufacturer in China. Loxin is a professional China mould company that designs as well as manufactures plastic molds for various sectors including home appliances and automotive etc.
What is injection molding?
According to Loxin, the technique used for manufacturing products made from plastic is known as Injection Molding. To manufacture a finished plastic product you will have to follow several steps even if this process is very easy to follow.
How is the injection molding process used?
The process of injection molding is commonly used for manufacturing various types of materials and products made from plastic. In this process, an injection molding machine is used to insert the molten plastic into the cavity of the mold designed into the shape of the product to be manufactured.
What can be manufactured with the injection molding process?
The injection molding process can be used to manufacture a large number of items that are used in day-to-day life from electrical gadgets to plastic components as well as interiors of your car, bottles for drinks, and coverings for the appliances in your household that are made from plastic. In this way, this process of plastic molding can be used to manufacture almost anything and everything made from plastic, you can see around you.
What is an injection molding machine?
A machine that is used for injecting molten plastic into the mold is known as an injection molding machine or injection press. It includes two main parts – the clamping unit and the injection unit. The mold is fastened in the clamping unit of the injection molding machine in a horizontal or vertical position depending upon the type and size of the product required. While injecting plastic into the cavities of the mold you can choose between hot and cold systems to run the machine, depending upon the type and size of the product to be produced.
Types of injection molding machines
Various types of plastic molding machines are used for making plastic products. These machines can be classified based on the system of driving them like mechanical, hydraulic, hybrid, and electrical.
Process of using a plastic injection molding machine
Initially it seems easy to use an injection molding machine to produce products made from plastic as molten plastic is injected into the mold and the product is removed from the mold after the mold cools down. But to complete this process several complicated steps are taken. These steps include:
Fastening: The mold is clamped in the clamping unit of the machine containing plated made from metal. In this first step of injection molding, the mold is clamped under pressure to adjust its alignment during the process of injection and cooling
Inserting: In this step, molten material of plastic, obtained by melting the plastic pallets in the machine’s barrel, is inserted or injected into the cavity of the mold under pressure through a ramming or screw device.
Housing: After injecting the molten plastic into the mold by using mechanical or hydraulic pressure, it is ensured that all the cavities of the mold are filled by exerting more pressure.
Chilling: After inserting molten plastid into the mold, it is left aside to cool down and allow to plastic to become solid
Releasing: The clamp is then loosened by releasing the pressure on the movable plate and mold is removed from the machine.
Ejecting: A plate, rods, and the blast of air are used to eject the plastic product produced by this process from the mold.
Finding an injection molding company for you
Now when you know the process of plastic injection molding, it will be easier for you to find the best plastic injection molding company in China. You can know the type of finished products you can expect from the company you choose by knowing the process they are using. Most of the China mold companies will allow you to get useful information about their manufacturing process through the videos available on their website whereas some may allow you to visit their facility personally. However to be sure about the best results you should not hesitate to ask a few questions from the manufacturer about the process of injection molding used by them
