Mechanical Design & Fabrication

RCAL can make prototype and production enclosures for your products.  We can create mechanical drawings for your concepts, and turn them into metal or SLA plastic prototype enclosures.   Plastic parts can be manufactured on shore at the neighboring plastic injection molding facility, or at our overseas partners.   In either case, we will monitor and ensure that the product is manufactured to our customer’s quality requirements.

Production Manufacturing & Rapid Prototyping

RCAL understands that quality is our customer's main concern. We work hard to find potential manufacturing pitfalls before they happen to ensure that quality products flow smoothly and consistently throughout the manufacturing process.


RCAL is equipped to support your manufacturing needs, from rapid-turn prototypes to full production-run quantities. We are currently placing Through Hole, Surface Mount, LGA, BGA and Micro-BGA components. RCAL can provide a project engineer for your prototype run to workout unexpected manufacturing issues and help refine your product for production. With our flexible manufacturing and design processes, you can count on faster time-to-market, minimized total outsourcing costs and suggestions for further improving products for manufacturability.  Count on RCAL to assure a quality product at a competitive price and superior support through all phases of design and manufacturing.
