Custom Injection Molding Technology Inc
From injection molding to 3D printing, there are a number of innovative plastic injection technologies that could be used to produce your prototypes. These six technologies are helping injection companies produce better and faster parts. Knowing these will help you when it comes time to select the right injection partner.
The 6 Main Type of Injection Molding Technology
1. Thin Wall Custom Injection Molding
Thin wall molding is an injection technique that creates a thin wall for a plastic part. This type of molding is commonly used for test apparatuses and other enclosed items. When it comes to thin wall molding, the operators have to consider various aspects of the part design and processing to ensure that the geometry holds up. Here at TEAM MFG, we use a sophisticated vision system to examine each completed part to ensure that no cracks have appeared.
2. Gas-assisted Custom Injection Molding
One of the most challenging parts of plastic injection is that it gets distorted as it cools. This can be avoided by shooting gas into a plastic injection mold, which allows the plastic to remain smooth and porous. This technique prevents the plastic parts from getting distorted as they cool down. It also helps minimize the cost of the part. This not only keeps the part from deforming during the cooling stage, but also lessens the cost of the part (as you’re using less material).
3. Metal Custom Injection Molding
Metal injection is a more expensive type of plastic injection that can be used for various applications. For instance, it is used to protect the cellular phone components from microwave radiation. The cell phone market, for example, sometimes uses metal injection molding to shield the cellular electronics from radio or microwaves.
4. Liquid Silicone Injection Molding
Thermoset plastic injection molding is commonly used for creating parts that can withstand extremely hot conditions. However, if you need a part that can also withstand chemicals, you may need to use thermoplastic injection.
5. 3D Printing
3D printing is also a notable technology that plays a crucial role in the creation of an injection molded part. Companies typically use this technology to create a 3D-printed prototype of their client's part before they proceed with manufacturing the finished product. This technology allows engineers to thoroughly inspect a part's potential improvement before it's printed. Currently, 3D printing technology can't produce parts with the tolerances required for an injection mold.
6. Unique Material Formulations
Aside from traditional plastic injection technologies, companies also use different materials for their molded parts. For instance, some companies may use a mineral filler or a blowing agent to add properties to a part. These additives and fillers can also be used to improve a part's electrical conductivity. For instance, a mineral filler or a blowing agent can improve a part's electrical conductivity. For instance, at TEAM MFG, we use a carbon-filled ABS to produce a high-quality electrical conductivity component. The temperature of the plastic material and the additives that are used in the process are also important factors to consider when selecting the right materials for your part.
