Water Treatment Injection Molding

NSF-Compliant Plastic Components for Water Treatment Systems

NSF-Compliant. Pressure-Rated. Built for Continuous Service.

Texas Injection Molding produces injection molded valve bodies, filter housings, flow control components, and equipment enclosures for water treatment equipment manufacturers who require NSF-compliant materials, pressure-rated design review, and consistent quality across production runs.

Water Treatment Injection Molding Solutions

Water treatment equipment operates at a demanding intersection: continuous pressure exposure, contact with disinfection chemicals including chlorine and chloramine, UV sanitization environments, and for drinking water applications, strict NSF/ANSI 61 and FDA compliance requirements for materials in contact with potable water.

The plastic components in filtration systems, UV disinfection units, softening equipment, chemical dosing systems, and monitoring instruments must maintain dimensional stability, mechanical integrity, and chemical neutrality across service lives measured in years. Texas Injection Molding produces water treatment components to these requirements.

NSF/ANSI 61 materials with potable water documentation.

Core Water Treatment Capabilities

Plastic component manufacturing for residential, commercial, and municipal water filtration, disinfection, softening, and monitoring systems

Filter housing bodies and sumps — standard and custom sizes in NSF-compliant PP and engineering materials

Valve bodies and seats — ball, check, and backflow preventer components

UV disinfection system components — lamp housings, quartz sleeve holders, flow chamber bodies

Chemical dosing components — metering pump heads, injection quills, and chemical feed fittings

Flow meter and sensor housings for water quality monitoring equipment

Distribution manifolds, unions, and fittings in NSF-compliant materials

NSF Compliance & Water Treatment Standards

Potable water contact components require NSF/ANSI 61 compliance. Our material sourcing, documentation, and process control support compliance throughout the production lifetime of your water treatment components.

NSF/ANSI 61 compliant resin grades sourced with full compliance documentation

Chemical resistance validation against chlorine, chloramine, ozone, and pH adjustment agents

Pressure-rated wall thickness and weld line review for continuous-pressure applications

Tight-tolerance production for flow-critical orifices, valve seats, and filter housing threads

NSF/ANSI 61 Compliance Documentation

We source and document NSF-compliant resin grades for potable water contact applications, maintaining the material certification trail required for NSF listing submissions.

For programs requiring NSF 61 listing, we provide the process documentation and material traceability that the listing body requires.

Pressure-Rated Component Integrity

Water treatment components operate under continuous hydraulic pressure — filter housings, valve bodies, and manifold assemblies that must maintain integrity across years of service.

Our DFM review addresses wall thickness at all pressure-bearing surfaces, gate location, and weld line placement before tooling is cut.

Why Water Treatment OEMs Choose TXIM

A trusted manufacturing partner for OEMs seeking precision, reliability, and US-based production.

NSF Compliance Expertise

NSF/ANSI 61 compliant material sourcing and documentation — the full certification trail required for potable water contact applications and NSF listing submissions.

Chemical Resistance Validation

Resin selection validated against chlorine, chloramine, ozone, and pH adjustment agents at service concentrations — not generic chemical resistance tables.

Tight-Tolerance Flow-Critical Production

Filter housing threads, valve seat surfaces, and metering orifices require shot-to-shot dimensional consistency. Our scientifically controlled processes deliver it.

Made in Texas

Domestic manufacturing for US water treatment programs — shorter lead times and transparent supply chain for systems serving US municipalities and commercial customers.

Clean Water Demands Consistent Parts

A filter housing that leaks at pressure, a valve seat that allows bypass, or a metering orifice that drifts in dimension over a production run — these failures affect water quality and public health. Texas Injection Molding produces water treatment components to the dimensional standards and material compliance requirements that water treatment systems actually require.

Our engineering team works with water treatment equipment manufacturers from DFM review through production validation, because the stakes of a field failure in water treatment equipment — measured in system downtime, compliance risk, and public health consequences — are too high to leave to chance.
