Custom Injection Molding for Any Application
At the core of Metro Custom Plastics' offerings is its custom injection molding service. The company specializes in producing parts tailored to exact customer specifications, whether for a low-volume prototype or a high-volume production run. Utilizing a wide range of thermoplastics and engineered resins, Metro delivers durable, accurate, and consistent components every time.

Prototype and Low-Volume Runs
For customers in the early stages of product development, Metro Custom Plastics provides prototype molding solutions. These short-run services are ideal for testing, evaluation, and design validation before committing to full-scale production, helping clients save time and costs during the development process.

High-Volume Production with Consistency
When it comes to large-scale manufacturing, Metro Custom Plastics excels at delivering high-volume injection molded parts with efficiency and repeatability. Automated production capabilities ensure consistent quality across every part, regardless of order size.

Overmolding and Insert Molding
Metro also offers overmolding and insert molding services to accommodate more complex part designs. Overmolding enables the production of components with multiple materials—such as soft-touch grips over rigid plastic parts—while insert molding allows for the integration of metal components, such as threaded fasteners or electrical contacts, during the molding process.

Assembly and Post-Processing Services
Beyond molding, Metro provides value-added services like part assembly, ultrasonic welding, adhesive bonding, and surface finishing. Whether customers require branded parts through pad printing or functional components with precision trimming, Metro ensures each finished product meets exact requirements.

Metro Custom Plastics provides expert guidance on resin selection, taking into account factors like strength, flexibility, UV resistance, and chemical compatibility. The company also offers design-for-manufacturing (DFM) consultations to help streamline production and reduce potential issues.
