Our Injection Molding Capabilities
At XTJ, our experienced team produces injection molded products of the highest quality. We use injection molding in tandem with our rapid tooling capabilities, allowing us to create detailed custom parts quickly and efficiently. Our injection molding technology allows us to use a wide range of materials and finishes to suit the needs of any industry or application.
Here are some of the options you can choose from:
Plastic Injection Molding
The most popular process for plastics, thermoplastic injection molding is suitable for consumer products, automotive components, and everything in between.
Liquid Silicone Rubber Molding
Liquid silicone injection molding is ideal for creating detailed, temperature-resistant parts from thermosets liquid silicone, either alone or with overmolding.
Metal Injection Molding
Suitable for small and detailed metal parts, metal injection molding is cost-effective in large volumes and wastes less material than CNC machining.
Addition Injection Molding Options
Besides the basic injection molding services, we also offer two variants on the process – overmolding and insert molding. Both of these can be useful in specific situations.
Overmolding uses injection molding to create a part from multiple materials. This process adds an injection-molded layer of material over an existing injection-molded workpiece. The overmolding process produces chemically bonded parts made using multiple materials.
The overmolding method is often cheaper and more effective than other manufacturing approaches that require creating and assembling component material parts separately. The process can also be used to build layered parts from scratch or to add a resistant outer layer to existing plastic parts and tools, providing a more rugged exterior. Toothbrushes consisting of a solid plastic body and rubberized grip are a common example of an overmolded product.
Insert molding is similar to overmolding, but the substrate is not necessarily plastic and does not have to be produced via injection molding. For example, insert molding can be used to add a plastic coating to a pre-fabricated metal part.
Common parts made by insert molding include sharp handheld tools, such as scalpels, which consist of a metal blade partially housed within a plastic handle. Insert molding is also frequently used to create products that incorporate bushings, clips, and fasteners
Injection molding is used to manufacture parts for a number of industries, including:
What is injection molding?
Plastic injection molding is the process of making plastic parts via the injection of molten plastic — typically a thermoplastic — into a metal mold, which is usually made from steel or aluminum.
The machine feeds raw material into the mold itself, the geometry of which is effectively a negative impression of the final part and which usually consists of two sections: an injection (A) mold and an ejector (B) mold.
The space between the two sections is the mold cavity, into which material is injected.
Although capable of producing a very wide range of parts, injection molding has some design constraints. Parts must have fairly narrow walls, should generally avoid overhanging features, and must have some degree of draft (tapered sides) so the part can be ejected from the mold.
Injection molding is principally used with plastics, and thermoplastics in particular. Thermoplastics are polymers that soften at an elevated temperature (at which point they can be freely injected into a mold) then return to a solid state after cooling. Injection molding also works with thermosets, which can be cured to make a solid but cannot then be melted back into a liquid state. Less common are elastomers.
