Why use injection molding for mass production?

Plastic injection molding is one of the most common methods for mass production of plastic products. Examples include chairs, disposable tableware, crates, toys, consumer electronics housings, Lego blocks, etc.


The injection molding machine consists of three main parts-injection unit, plastic injection mold and fixture. The barrel heats the plastic particles. These molten plastics will move forward in the barrel through the screw system. Once completely melted, it will be "injected" into the mold cavity and formed. It will cool and harden to form a plastic part.

Injection molding automates the mass production process. One injection may result in the production of many parts, depending on your mold design. There are many types of molds that can further increase the productivity of a single injection of molten plastic, such as laminated molds, tandem molds, and multiple cavitation molds.

When we choose mass production, we will definitely support predictability, efficiency and less troubleshooting. Plastic injection molding is undoubtedly an established manufacturing method. High-precision engineering plastic materials can be bought on the market to advanced injection molding machines to meet different manufacturing requirements.

Mass production using injection molds is very useful for achieving higher efficiency. Once the design is designed for a specific purpose according to the customer's choice, the molding process will not take long. This makes it more effective in mass production and also more effective in terms of yield.

It has enhanced strength.

It is very common to use additives such as glass fibers in plastic materials. These highly engineered composite plastic materials have the durability of their raw materials. And, there are thousands of different types of materials on the market to meet different needs.

Most importantly, the density of the plastic when it is just molded makes it stronger. There is a great need for durable parts in the market, and plastic injection molding provides you with a lot of flexibility that other molding processes cannot provide.
