Comprehensive Plastic Injection Molding Services
To meet a wide range of customer needs, API offers plastic injection molding services with press tonnage from 220 to 1,000 tons. This gives you flexibility for both low- and high-volume production—while keeping quality and lead times under control.
Engineering & Design Support
First, our engineers work with you to refine your part for efficient production, long-term durability, and cost control. We can convert designs from metal, wood, or other materials into high-performance injection-molded components. In addition, 3D printing allows us to create prototypes quickly and make improvements faster before full production begins.
Over Molding
We use two-shot injection molding to combine multiple materials or colors into one finished part. This process creates strong, durable components that meet your exact design requirements.
Insert Molding
Insert molding allows us to mold plastic around metal or other materials to create one solid, finished part. Our controlled processes ensure each insert is securely placed and built for long-term performance.
Precision Trimming
After molding, CNC trimming helps ensure clean edges, consistent dimensions, and a finished part that’s ready for assembly or shipment
Assembly
To simplify your supply chain, we provide assembly options including sonic welding and other value-added services.
Shipping
Finally, we offer drop shipping for customers without extensive warehousing—helping you deliver product where it needs to go, on schedule.
