Our Quick Turn Prototyping Services

Integrated design, prototyping, machining, molding, casting, and finishing services for plastic product development.

CAD Modeling

Convert concepts, drawings, scans, or existing designs into manufacturable digital models. Design refinement and geometry modifications help prepare plastic parts for prototyping or production.

3D Printing

Produce complex components, design iterations, patterns, fixtures, models, and low-volume applications quickly, allowing teams to evaluate designs before committing to tooling.

Urethane Casting

Create production-representative plastic components for prototypes and low-volume production. Urethane casting bridges the gap between 3D printing and injection molding.

CNC Machining

Develop precision prototype and low-volume components for functional testing, tooling, fixtures, and production-quality applications requiring engineering-grade performance.

Injection Molding

Support the transition from prototype development into repeatable plastic-part production while evaluating tooling and manufacturing strategies against product requirements.

Production Painting

Add color matching, surface preparation, cosmetic finishing, and presentation-quality paint finishes to customer-facing products, sales models, and high-fidelity prototypes.

Integrated Product Support

Accelerate Plastic Product Development

Quick turn prototyping helps product teams test form, fit, function, and presentation before moving into larger production decisions. Finine Design and Manufacturing combines CAD modeling, 3D printing, urethane casting, CNC machining, injection molding, and finishing under one partner. Its San Diego facility supports demanding automotive, military, consumer electronics, dental, and orthopedic product development needs.
