Da/Pro Rubber Inc

What Da/Pro Rubber Inc does

Da/Pro Rubber, Inc. is a privately held, founder-owned custom manufacturer of precision rubber, thermoplastic elastomer, and plastic molded components, founded in 1961 by Charles Daubenberger Sr. and headquartered in Broken Arrow, Oklahoma (Tulsa area). The company operates five manufacturing facilities across the United States (Broken Arrow HQ, Owasso, and historically Valencia, California and Newburyport, Massachusetts), Singapore, and Malaysia, and ships parts to customers in over 50 countries. Its core capabilities span compression molding, transfer molding, injection molding (including liquid silicone rubber / LIM-LSR), micro molding (down to 0.051 inch O-rings), two-shot molding, overmolding, and plastic injection molding, supported by in-house custom compounding with ingredient-level traceability, proprietary compression press engineering, in-house mold design and tooling, and a 5,000 sq ft Class 10,000 clean room.

The company sells primarily to enterprise OEMs across five verticals: medical devices, aerospace, oil & gas, electronics, and industrial manufacturing. GTM is sales-led via a network of regional territory managers across the U.S., Canada, Greenland, and Asia, with a European channel partner (MedNet GmbH) supplementing international reach. Pricing is quote-based and project-specific; revenue is generated from custom part production, custom compounding services, prototyping, and value-added services such as sub-assembly, special packaging, hot stamping, and silk screening. Differentiators cited by the company include proprietary molding presses and processes, custom compound development with full traceability, and regulated certifications (ISO 9001, ISO 13485, ITAR registration, WBENC certification).

Da/Pro remains privately held by the Daubenberger family with no institutional funding, parent company, or M&A history disclosed. The current CEO is Gretchen Brauninger. Operational scale sits at 251–500 employees, with active commercial investment reflected in a 2026 industry trade show schedule spanning MD&M West, multiple D2P regional events, and Space Tech.

Differentiator

Problem solved

Functional benefit

Products and services

• Compression Molding Proprietary rubber compression molding process using automatically controlled in-house machines, delivering high precision, tight tolerance, and virtually flash-free custom molded rubber components for OEMs.
• Transfer Molding Proprietary transfer molding process that monitors all variables and compensates for differences each cycle, producing consistent, tight tolerance, virtually flash-free custom rubber parts.
• Rubber Injection Molding (LIM/LSR) Liquid injection molding process using liquid silicone rubber (LSR) for faster cycle times, ability to make custom shapes with minimal flash, and suitability for high volume production of custom molded parts.
• Rubber Micro Molding High-precision micro molding process for manufacturing rubber O-rings as small as 0.051 inches, valves, and custom shapes with tight tolerances and minimal flash.
• Overmolding Rubber overmolding onto plastic or metal substrates, combining components into single molding operations to reduce secondary processes and costs for custom OEM parts.
• Plastic Micro Molding Micro molding process producing tight tolerance plastic parts for critical applications in medical, aerospace, industrial, and electronics industries.
• Plastic Injection Molding Plastic injection molding manufacturing plastic housings and custom components for medical, aerospace, industrial, and electronics industries from a 30,000 sq ft dedicated facility.
• Two-Shot Molding Two-shot plastic injection molding process for creating gaskets, seals, buttons, switches, knobs, caps, and enclosures, eliminating the need for secondary assembly operations.
• Custom Compounding In-house custom organic or silicone compound development and mixing with ingredient-level traceability, including custom color matching for branding and application-specific requirements.
• Prototyping Services Prototype development including tool prototype design, functionality testing, fused deposition models, machined prototypes, and single cavity prototype molds for OEM customers.
• Custom Molded Components Custom manufactured parts including O-rings, gaskets, seals, diaphragms, bellows, connectors, assorted parts, rubber shapes, rubber-to-metal components, umbrella valves, keypads, and assorted plastics for OEM customers.
