Our Injection Molding Capabilities
In First Part, experienced team for plastic injection molding service. Our injection molding and rapid processing services perfectly match. We can efficiently and accurately complete custom parts.At the same time, our injection molding services can suit the application requirements of any industry.
Mold Making

Our competence and capabilities are centered around integrating digital manufacturing technologies with conventional manufacturing processes. This is why we can use high-quality 3D designs to rapidly manufacture high-precision mold tools in a matter of days.
We offer rapid tooling, mold making, and die manufacturing for both low-volume production, mass production, and prototyping. Our expertise includes steel, and aluminum tooling, and mold maintenance, redesign services.
Plastic Injection Molding

First Part uses high-quality thermoplastic materials to deliver top-grade plastic injection molded parts in as quick as 7 days. From our instant quoting service to design evaluation, toolmaking, die, and mold production, and finally injection molding, we stay true to our promise of quality.
Our entire injection molding capabilities include insert molding, mold making, rapid tooling, and overmolding.
Overmolding

Overmolding is an injection molding operation that is used to make a single part from multiple materials. At First Part, we can mold a thermoplastic material into a second material to leverage certain performance and characteristic attributes of the materials to complement functionality. An example is the solid plastic body and rubberized handles of toothbrushes. Overmolding is very effective for creating composite parts, costing lesser than other production techniques that require assembly of separate components.
Insert Molding

Insert molding is one of First Part’s injection molding capabilities, enabling us to create or integrate plastic fragments and components (inserts) to the pre-fabricated metal part. Through our expertise in cross-technology fabrication, we can use sheet metal and CNC machining to make units of your metal part and employ insert molding to introduce plastic parts. Insert molding can be used in making tools that are sharp and require a grip. Examples include scalpels, fasteners, bushings, or clips.
Injection Molding Applications
First Part Injection Molding Operations can be applied in:

· High-functional end-part production
Injection molding is widely used in making functional end-use parts that will replace metal parts in most components. Choose from materials to finishes to make high-quality parts that are of high strength and less weight than metal counterparts.

· Rapid tooling/Mold making
We can use our optimized injection molding process to manufacture molds, tooling (cores and cavities), and dies for use in making any range of budget, volume, and production times.

· Rapid Prototyping
Take advantage of low-cost tooling options to allow you to make highly-functional parts that are suitable for functionality testing. Even when tooling with aluminum molds, our injection molded parts are almost certain to outperform 3D printed or CNC machined parts from the same material. A low-cost mold can be made in a shorter window, and depending on size and geometry, it could be used in making many volumes. (up to thousands of prototypes)

FAQs – Plastic Injection Molding
What Injection molding capabilities does First Part have?
First Part’s Injection molding capabilities are reliable, precise, and scalable. Our robust manufacturing hubs make us one of the most trusted outlets for general metal and plastic fabrication. Here’s a summary of all our injection molding capabilities.
What are the advantages of Plastic Injection Molding?
Plastic injection molding is one of the cost-efficient methods of making thousands of finished parts quick and accurate. One tooling has been completed, the other parts can be fabricated in large volumes that any other manufacturing technique.
How long does mold tooling take?
Depending on the volume of parts, the need for heat treatment, design, and geometric complexities, a standard plastic injection molding tool can take anywhere between 7 – 10 days to manufacture.
