Plastic injection molding
Injection molding is the manufacturing process of injecting high-pressure thermoplastic into a mold. Ideal for high-volume production with consistent quality.
Insert molding
A manufacturing process in which a part is molded around a pre-installed insert in the tooling for enhanced functionality.
Overmolding
A manufacturing process in which one plastic material is molded over another to create a single component with multiple properties.
Liquid silicone rubber molding
A thermoset process that involves mixing a two-part solution together to produce flexible and durable parts.
Tooling options
Choose between prototyping and production tooling based on your volume requirements.
Prototyping
- Ideal for rapid prototyping and low-volume production
- Tool shot life – 1k to 100k units
- Fast turnaround and cost-efficient construction
- Aluminum or steel tooling
Production
- Longer-lasting tooling for larger volumes
- Tool shot life – 100k to 1M units
- Automated production for cost-efficiency at higher volumes
- Hardened steel for longer life and scalable unit price
Gallery of injection molded parts
Here's a small selection of the injection molded prototypes and end-use parts we've produced for our customers.
Injection molding materials
We can generate instant injection molding quotes for 15+ thermoplastics and thermosets.
Thermoplastics
ABS
Acrylonitrile Butadiene Styrene offers excellent impact resistance, good mechanical properties, and is easy to process. Ideal for consumer products and housings.
Polycarbonate
High impact strength, optical clarity, and heat resistance. Perfect for transparent parts, safety equipment, and electronic housings.
Nylon (PA)
Excellent wear resistance, low friction, and good chemical resistance. Commonly used for gears, bearings, and structural components.
Specialty Materials
We can source any other material on request, but quotes take up to 48 hours.
Secondary operations
We offer several secondary operations such as painting or heat tapping inserts. You can specify which secondary operations are needed in your quote request.
