SHD specializes in one-stop service of general and high-precision tooling from design, processing & fabrication, tooling trail, mass production to supply chain management.
Excellence Manufacturing Every Time
As the demand for clean water solutions escalates worldwide, injection mould manufacturers require tooling that can produce high-pressure resistant housings without compromising on cycle time.
Engineered to meet the rigorous demands of the global water purification industry, this SHD’s precision injection mould series sets a higher standard for durability, clarity, and structural integrity.

“Our goal was to create a mould that doesn’t just produce a part, but ensures the safety and reliability of the entire filtration system,” says the Head of Engineering at SHD. “By utilizing advanced flow analysis and precision CNC machining, we’ve eliminated common defects like weld lines and air traps that usually plague thick-walled filter housings.”
The injection water filter housing mould is compatible with various materials, including PP, PP+10–30GF, ABS, SAN and POM. This provides manufacturers with the flexibility to produce both opaque and transparent units for residential or industrial use.
Our injection molding capabilities ensure stable production of connectors, housings, valves and other functional parts. This is particularly true for parts with strict dimensions and sealing requirements.
As the water treatment industry continues to evolve, having a reliable precision injection mould partner is essential. It is the key to maintaining a competitive edge.
SHD remains dedicated to pushing the boundaries of what is possible in plastic injection molding. This ensures that our clients receive not just a mould, but a comprehensive solution for long-term production success.
Q1: What materials are best suited for SHD’s water filter housing moulds?
A: Our moulds are versatile and optimized for several high-performance resins. For transparent housings, we typically recommend AS (Acrylonitrile Styrene) or PC (Polycarbonate). For opaque, heavy-duty industrial housings, Reinforced Polypropylene (PP) is the preferred choice due to its excellent chemical resistance and cost-effectiveness.
Q2: How does SHD ensure the burst pressure resistance of the molded housing?
A: Safety is our priority. We utilize Moldflow Analysis during the design phase to optimize gate placement and wall thickness. This ensures uniform material distribution and eliminates structural weak points like knit lines, allowing the final product to pass rigorous high-pressure burst tests.
Q3: Can the mould design be customized for different filter cartridge sizes?
A: Yes. SHD provides fully customizable tooling solutions. Whether you require standard 10-inch or 20-inch lengths, or “Big Blue” style large-diameter housings, our engineering team can adapt the plastic injection water filter housing mould specifications to meet your unique dimensions and thread requirements (NPT/BSP).
