Using a plastic crate mould, you can make different types of plastic crates. These crates are made from polyethylene and have good tensile resistance and compression strength. They are often used to store dairy products or organize eatables. These crates are easy to clean and make transportation of bulky items easier.
There are several types of plastic crates and each of them has a unique shape and design. There are also various kinds of fabrication methods used in making them. Some manufacturers prefer to use recycled materials instead of new materials. Plastic crates are used in the food and beverage industry as well as logistics industry.
For producing plastic crates, you need a high speed injection molding machine. A high speed machine is needed because it can increase both the melt and injection speed. Besides, it also improves the quality of the molded plastic. If you are using an injection molding machine, you need to make sure that the screw RPM is high enough to ensure good production.
To produce durable plastic crates, you need to choose a low MFI (metal filling index) HDPE (high density polyethylene) that is durable and strong. You can also add antioxidants or UV protectants to polyethylene to make it more resistant to UV degradation.
For producing plastic crates with open crates, injection molding is the best choice. The process involves loading the plastic resin powder into the mold and rotating it while it melts. Then, inert gas is introduced into the mold, which pushes the plastic onto the mold surface and partially fills it. After the plastic is cooled, it is removed.
Normally, a crate mould is used for producing large quantities of at least 500 000 parts. The mould is usually made of four side walls with lots of ribs perpendicular to the open direction. If there are openings on the sides of the mould, the plastic can flow out of the mold to form the desired shape.
Using the right steel is very important in making a plastic crate mould. For the base of the mould, it is best to use steel over 35 HRC. It can be easily machined and can be used for different shapes and designs. You can also use aluminum, which is light, ductile and has high tensile strength. The aluminum is very easy to handle and also has a high level of corrosion resistance.
You also need to ensure that the surface of the mould is smooth and free from imperfections. It should also be free from any cracks or joints that can damage the plastic if not taken care of. You need to make sure that you are using the right steel for the main steel, the handle and the mould base.
The other parts of the mould should also be made from durable materials that can withstand the wear and tear of the production process. The handle area and the openings should also be machined with precision. You also need to make sure that you are using a good guiding system.
