Precision Injection
Molding for Building Systems and Construction
Job-Site Tough. Code-Compliant. Made in Texas.
Texas Injection Molding manufactures injection molded electrical fittings, plumbing components, HVAC parts, fastening hardware, equipment enclosures, and infrastructure components for OEM building product manufacturers that require consistent quality, code-compliant materials, and scalable U.S.-based production.
Injection Molded Building Systems Components
Plastic components used in building systems face demanding real-world conditions. They must withstand chemical exposure from concrete, solvents, water-treatment products, and cleaning agents. They must tolerate mechanical abuse during installation, shipping, storage, and job-site handling. Outdoor components must resist UV exposure, moisture, and temperature swings. Electrical, plumbing, HVAC, and fire-protection components may also need to meet strict code, listing, and material compliance requirements.
Texas Injection Molding produces injection molded components for OEMs and product manufacturers serving the building products, construction, infrastructure, electrical, plumbing, HVAC, and industrial equipment markets.
UL flame-rated conduit fittings and junction box components
Core Construction Injection Molding Capabilities
Plastic component manufacturing for electrical, plumbing, fastening, HVAC, and structural construction applications
Electrical Fittings: Conduit fittings, locknuts, bushings, and liquidtight connectors.
Weatherproof Enclosures: Junction boxes, enclosure bodies, covers, and knockouts.
Plumbing Components: Pipe and plumbing fittings in PP, CPVC, and NSF-compliant materials.
Fastening Hardware: Plastic anchors, cable clips, conduit straps, and related anchoring components.
Equipment Housings: Power tool and site equipment housings, component covers, and protective shells.
HVAC Components: Duct fittings, register boots, diffuser components, and mechanical covers.
Code Compliance & Quality Standards
Construction components must meet NEC, UL, NSF, and applicable building code requirements. Our material selection and process documentation support compliance from design through production.
UL 94 Flame-Rated Materials: NEC-compliant electrical conduit and junction components.
NSF-Compliant Materials: Potable water plumbing applications requiring approved resin grades.
Impact-Modified Resin Grades: Validated for job-site handling and installation loads.
Process Documentation: Supports UL and third-party listing submissions.
UL Flame Rating for Electrical Components
Electrical conduit fittings and junction box components near current-carrying assemblies require UL 94 V-0 or V-2 flame ratings. We select, validate, and document flame-rated materials at the actual production wall thickness — not just datasheet specifications.
Volume for Construction Program Scales
Construction programs often require large annual volumes with predictable seasonal demand patterns. Our multi-cavity tooling and press capacity scale to meet construction product volumes without compromising quality or lead time.
Why Building System & Construction OEMs Choose TXIM
A trusted manufacturing partner for OEMs seeking precision, reliability, and US-based production.
Flame Rating Expertise
UL 94 flame-rated conduit fittings, junction boxes, and electrical components — with process documentation that supports UL listing submission.
Code-Compliant Material Selection
NEC electrical, NSF plumbing, and applicable building code compliance starts with the right material. We specify and document compliant resins for each application.
High-Volume Capacity
Multi-cavity production tooling and press capacity for the large annual volumes that construction product programs require.
Made in Texas
Domestic manufacturing for construction product brands. No import lead times, no overseas quality risk, and US-origin documentation for government projects.
Built for the Job Site, Certified for the Code
Building System or construction plastic parts that fail a code inspection or an UL audit cost more than the parts themselves — they delay projects and damage supplier relationships. Texas Injection Molding produces construction components that arrive documented, compliant, and ready for installation.
Our flame rating expertise and code-compliance material knowledge means we catch compliance requirements at the design stage, before tooling is cut — not at the certification audit.
