Our Plastic Injection Molding Services

Integrated capabilities that support plastic parts from design refinement and prototypes through production and final finishing.

Injection Molding

Produce repeatable plastic parts for high-volume manufacturing needs. Our injection molding capability integrates with upstream design and prototyping work to help streamline the transition into scalable production.

CAD Modeling

Create and refine detailed 3D product models that prepare components for prototyping and manufacturing. CAD support helps establish a clear foundation before tooling and production decisions are made.

3D Printing

Turn digital designs into physical prototypes quickly for evaluation and iteration. This capability helps teams test form, fit, and product direction before progressing toward production manufacturing.

CNC Machining

Fabricate precise prototype and production-level components using CNC machining. This complementary capability supports product development alongside injection molding, casting, and other in-house manufacturing services.

Urethane Castings

Bridge prototype development and full-scale molding with low-to-medium-volume urethane castings. This option provides quality parts for testing, review, and production requirements where molding may not be the immediate fit.

Production Painting

Add professional-grade paint finishes to manufactured parts and products. Production painting supports aesthetic and functional finishing requirements for automotive, military, electronics, and medical applications.

Integrated Manufacturing Support

From Product Design to Production

Plastic injection molding works best when it is connected to the full product-development process. Finine Design and Manufacturing combines CAD modeling, rapid prototypes, CNC machining, urethane casting, molding, and finishing under one roof in San Diego. That integrated approach can reduce vendor coordination and help teams make informed design refinements before moving into repeatable production for demanding automotive, medical, defense, and electronics applications.

Frequently Asked Questions

What is plastic injection molding?

Plastic injection molding is a manufacturing process that injects molten plastic into a shaped mold cavity, where it cools into a repeatable part. It is commonly used when a product requires consistent components at higher production volumes. Part geometry, material requirements, anticipated quantity, finish needs, and design tolerances should be evaluated early to determine whether molding is the right production method.

When should I choose injection molding instead of 3D printing?

Can you help prepare my product design for molding?

What industries do you support with injection molding?

Do you offer prototyping before production molding?

Can you finish or add graphics to molded plastic parts?
