Custom Molded & Machined Cell Housings for OEM Brands
In the highly specialized field of water electrolysis, the performance of a titanium electrode stack is heavily dependent on the structural integrity and hydraulic design of its enclosure. Century operates as a dedicated OEM electrolytic cell manufacturer, bridging the gap between internal electrode engineering and external pressure vessel fabrication.
Whether your engineering team is launching a new line of high-volume residential chlorinators or developing a bespoke, low-volume skid for industrial chlor-alkali production, we possess the comprehensive manufacturing infrastructure to realize your design. By offering both high-tonnage plastic injection molding and precision CNC machining under one roof, we eliminate the need to fragment your supply chain across multiple vendors. Bring us your CAD files, and we will deliver pressure-tested, assembly-ready vessels that strictly adhere to your proprietary specifications.

Dual Manufacturing Capabilities: Molding vs. Machining
Understanding the commercial lifecycle of your product is critical to selecting the right fabrication method. We guide our OEM partners through this process to optimize both Non-Recurring Engineering (NRE) costs and unit economics.
- High-Volume Injection Molding: For standardized pool equipment and high-turnover commercial systems, economy of scale is paramount. We cut custom steel molds in-house to produce heavy-wall Polycarbonate (PC) and Acrylic (PMMA) vessels. Once the initial tooling investment is amortized, this method delivers flawlessly consistent, high-pressure-rated housings at a drastically reduced per-unit cost.
- Low-Volume CNC Machining: When designing large-scale industrial systems, or during the early-stage prototyping of a new cell, investing in a steel mold is financially impractical. For these applications, we produce a CNC Machined Plastic Housing. Starting with solid UPVC billets and heavy-wall extruded acrylic tubes, our multi-axis CNC routers carve out Custom Machined Housings to exact tolerances. This process requires zero tooling investment, allowing for rapid iterations, extreme size scalability, and highly specific flange or threading configurations.
The Century Advantage for Contract Manufacturing
Why entrust your proprietary designs to Century? Because sourcing Machined Cell Housings (Custom) or custom molds from generic plastic shops often results in disastrous fitment issues when the titanium plates are finally installed.
As a fully integrated factory, we manufacture both the internal titanium MMO electrodes and the external plastic housings. We deeply understand the thermal expansion, gas venting requirements, and precise dimensional clearances required between the active plates and the vessel walls. By vertically integrating your supply chain with us, you guarantee that your electrode stacks will slide perfectly into their enclosures every single time. Furthermore, we operate under strict Non-Disclosure Agreements (NDAs), ensuring your intellectual property and custom CAD designs remain completely protected.
It depends on your scale and pressure requirements. Molding is ideal for high-volume, high-pressure residential parts where unit cost is critical. Machining is required for large-scale, custom industrial chambers or early-stage prototyping where flexibility and zero tooling costs are prioritized.
Absolutely. For injection-molded projects, we can design mold inserts to permanently emboss your corporate logo into the plastic. For machined vessels, we offer custom laser engraving and industrial-grade labeling on the UPVC end-caps.
Depending on the complexity of the geometry and the size of the housing, designing, cutting, and sampling a new steel injection mold typically requires 35 to 45 days before full production runs can commence. CNC machined prototypes can often be turned around in less than 14 days.
