Injection Molding Processes
Transition seamlessly from prototyping to on-demand manufacturing for affordable, high-quality molded parts in just a few days. Even better, your prototyping tool becomes free when you switch to an on-demand manufacturing tool. Partnering with a single supplier that offers free design consultation significantly accelerates the production process, enhancing supply chain flexibility, ensuring more consistent parts, and simplifying the qualification process.
Insert Molding is a manufacturing process in which resin is heated in a barrel until it reaches a molten state, then injected into a mold to create a final, production-grade thermoplastic part.
Liquid silicone rubber (LSR) molding is a thermoset process where a two-component compound is mixed and then heat-cured in the mold using a platinum catalyst to produce the final part.
Overmolding and insert molding are two-part injection molding processes in which one material is applied over a second substrate or metal insert, forming a single integrated component.
Micro molding produces minute, intricate plastic components through injection molding, serving industries like electronics, medical devices, and micro-mechanics.

Surface Finish Options
We offer a variety of high-level surface finishes and only some common finishing options are listed as below. There are more finish options for custom injection molding parts.
Painting
Applying a protective or functional coating to surfaces. It involves the application of liquid paint and then undergoes a curing process to solidify the paint film.
Silk Screen
Applying images, patterns, or text to surfaces.
Laser Marking
Labeling, engraving, or adding information to materials. It involves using a laser beam to alter the surface of the workpiece, creating visible marks without physical contact.
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 FAQs
Yes, we offer a production tooling option called on-demand manufacturing. This tooling option provides several benefits: lower piece part price, multi-cavity capabilities, guaranteed tooling for the life of the project (we will cut a new tool if it wears out), and first article inspections.
In most cases, we can maintain a machining tolerance of +/- 0.003 in. (0.08mm) with an included resin tolerance that can be greater than but no less than +/- 0.002 in./in. (0.002mm/mm).
