ABS/PC Water Filter Injection Mold
Custom injection mold for ABS/PC water filter housings with multi-cavity layout, balanced filling and stable production cycle.

Project Notes
- Water filter housing molds require pressure-resistant structure, sealing surface control and stable thread forming.
- Engineering review covers material selection (ABS or PC), gate position, parting line, cooling layout and cavity quantity.
- Suitable for household water filter, industrial filter and water purification product mold development.
Basic Information
- Application: water filter housing
- Process: injection molding
- Material: ABS / PC
- Cavity: multi-cavity option
What this mold project needs to solve
Water filter housings need to withstand internal water pressure while maintaining dimensional accuracy for assembly. The mold must produce consistent parts with reliable thread quality, sealing surfaces and structural integrity.
Shengqi reviews the filter housing drawing, including inlet/outlet positions, thread specifications, wall thickness, transparent or opaque material requirements, and expected production volume before mold design.
For multi-cavity water filter molds, filling balance and cooling uniformity across all cavities are critical to maintaining part consistency and reducing scrap rate during production.
Key points reviewed before tooling
Sealing Surface Control
Water filter housings have critical sealing areas. Mold precision at parting lines, O-ring grooves and thread interfaces directly affects product performance and leak prevention.
Thread Forming Design
Internal and external threads require careful unscrewing mechanism or slide design. Thread quality, release reliability and mold maintenance are reviewed before tooling.
Pressure Resistance Structure
Filter housing wall thickness, rib layout and material selection are reviewed to support product pressure requirements and molding stability.
Multi-Cavity Balance
For multiple cavities, runner balance, gate sizing, cooling layout and filling analysis help ensure consistent part quality across the production run.
