Injection Molding Processes
Make the move from prototyping to on-demand manufacturing for affordable, high-quality molded parts within days. Better yet, your prototyping tool is free once you shift to an on-demand manufacturing tool. Working with a single supplier that provides free design consultation services also massively speeds up the manufacturing process, allowing for greater supply chain flexibility, more consistent parts, and making qualification a breeze.
Plastic Injection Molding
Plastic injection molding is a manufacturing process where resin in a barrel is heated to a molten state, then shot into a mold to form a final production-grade thermoplastic part.
Overmolding & Insert Molding
Overmolding and insert molding are two-part injection molding processes where one material is overlaid onto a second substrate part or metal insert to create a single component.
structural foaming molding
In the foam forming process or foam polymer material, the honeycomb or porous structure is formed through the addition and reaction of physical blowing agent or chemical blowing agent.
Gas-assisted injection molding
Gas-assisted injection molding is to inject high-pressure nitrogen directly into the plastic being plasticized in the mold cavity through the main and auxiliary controllers (segmented pressure control system), so that the plastic part expands internally and creates a hollow, but still keeps the product and shape intact.
Liquid Silicone Rubber Molding
Liquid silicone rubber molding is a thermoset process that mixes a two-component compound together, which is then heat cured in the mold with a platinum catalyst to produce a final part.
Coating technology
The plastic injection molding process refers to the injection molding process in which a silicone material is injected into the plastic products that have been injection molded to form two-color or multi-color products.
Consistency and Quality
We combine scientific (or decoupled) molding techniques, which optimize and lock in processing parameters to ensure part consistency—with extra attention paid to critical-to-quality dimensions using our proprietary automated CMM process. Plus, with every order you’ll get:
1.Comprehensive manufacturing analysis
2.Consultative design services
3.Quality reports like FAIs and process capability reports

Why Choose Us for Custom Injection Molding?
Unmatched Lead Times
Reduce your product development cycle by weeks—sometimes months—and bridge to production with injection-molded parts within days. Some injection molding orders can ship in as fast as 1 day.
Design for Manufacturing Feedback
Every quote includes real-time pricing and design analysis. We evaluate your 3D CAD and help identify any features that may pose challenges during the molding process such as difficult to machine undercuts and insufficient draft.
No Minimum Order Quantities (MOQs)
Procuring parts on demand, without MOQs, helps you manage market or demand volatility and provides a cost-effective source for bridge production, line-down emergencies, end-of-life production, or product customization.
Injection Molding Expertise
We’ll work with you throughout the course of your project to help you quickly move from prototyping to production, including finishing options and inspection reporting.
Advantages of Injection Molding
Injection molding is plastic manufacturing process that can produce high quality parts at scale. It’s typically used for low- to high-volume production but our aluminum tooling can also make prototyping runs economical.
- Low cost at higher volumes
- Exceptional part cosmetics and surface finish
- Repeatable
- Complex parts
- Low scrap rate
- Large selection of thermoplastic and thermoset materials
Injection Molding Applications
Injection molding is widely used for plastic part production in medical, consumer, aviation,and automotive industries. Typical parts include:
- Housings
- Brackets
- Gears
- Single-use medical parts
- Electrical connectors
- Syringes
- Containers
