Excellent Material Selection
You need a dependable drain system. ZL101A aluminium alloy provides excellent strength to weight ratio.
This material is very resistant to corrosion in humid situations. With a weight of 0.56kg, it allows for quick installation and structural integrity.
Advanced Manufacturing Process
Sand casting is capable to produce intricate geometries that other technologies can't. The method provides complex internal channels needed for optimal water movement.
Our method results in smooth inner surfaces which minimise turbulence. Less noise, better drainage performance.
CNC Machining
Each component is CNC machined for necessary dimensions after casting. This stage ensures total alignment with connected pipes and fittings.
Tight tolerances enable leak free installations. All the connection points in your projects are done professionally.
Advanced Surface Treatment
Shot blasting removes all contaminants and results in a homogeneous surface structure. If you need some extra layers of protection, this procedure will boost the coating's adhesion.
This technique also increases fatigue resistance for long term durability. Your installation is engineered for long service life under environmental stress.

Q: Can you modify the elbow angle for specific drainage requirements?
A: Yes, our ODM service accommodates custom angle specifications. Provide your preferred angle with technical drawings, and we'll develop suitable molds for your project.
Q: What tolerance levels do you maintain for CNC machined surfaces?
A: We maintain tolerances within ±0.1mm for critical dimensions. This precision ensures proper sealing and alignment in your drainage assemblies.
Q: How does sand casting compare to die casting for elbow pipes?
A: Sand casting excels for complex internal geometries and lower volume production. It offers design flexibility that die casting cannot achieve for intricate water channel shapes.
Q: What is your typical lead time for custom mold development?
A: Mold manufacturing requires approximately 15-25 days. Batch production follows within 7-20 days, totaling 20-30 working days for complete orders.
Q: Do you provide material certificates for the ZL101A aluminum alloy?
A: Absolutely. We supply material certificates and test reports with each shipment. These documents support your quality verification and compliance requirements.
