WAFU
Leak Testing for Hardware Die-Casting Parts
Wafu Brothers plays a vital role in leak testing within the hardware die-casting industry, providing high-precision testing equipment. Their technology is widely applied in leak testing of hardware die-cast parts, ensuring the leak of various metal housings and structural components; used for leak detection of valve bodies and pump bodies, guaranteeing operational safety; and also supports automotive housing leak testing and power tool housing testing, enhancing product reliability and service life. Wafu Brothers offers reliable assurance to the hardware die-casting industry with advanced technology, becoming an important partner for die-cast manufacturers.
AC Component Cover
Complies with environmental standards: Excessive refrigerant leakage violates the Kigali Amendment and local environmental regulations, resulting in heavy fines.
Ensures cooling performance: Every 10% refrigerant loss reduces cooling efficiency by 15%–20%, leading to poor cooling performance.
Prevents air and moisture ingress: Moisture can freeze at the expansion valve, causing blockages and frequent system shutdowns.
Maintains stable system pressure: Even tiny gaps or micro-leaks can cause high-pressure side leakage, reducing discharge pressure and condensation performance.
Mold Die Casting Parts
Process-related defects: During high-temperature and high-speed filling, internal defects such as porosity, shrinkage cavities, and micro-cracks may occur.
High sealing requirements: As molds in real applications, these parts often operate under pressure media and alternating vacuum/positive pressure environments.
Ensures service life: Sealing issues may not appear immediately but worsen over time, eventually causing mold failure or production downtime.
Ensures forming accuracy: Leakage affects pressure distribution in the mold cavity, leading to product defects.
Stern Cover Die Casting Parts
Key structural component: Critical metal structure at the stern, made of aluminum or magnesium alloy die casting.
Multiple functions: Protects propellers, rudders, and shafts, providing flow guidance, corrosion resistance, and vibration reduction.
High sealing requirement: Long-term underwater operation requires excellent airtightness; leakage may cause water ingress and failure.
Impact on vessel safety: Leakage can lead to water entering motors, transmission systems, and bearings, posing safety risks.
Automotive Die Casting Parts
1. Test area: Sealing performance of the entire cavity of the die casting part.
2. Function: Prevent engine abnormalities caused by poor sealing, reduce complaints and rework, and improve customer satisfaction.
3. High sealing requirement: High-pressure working environment requires excellent airtightness; even slight leakage reduces performance.
4. Safety impact: Leakage may cause oil/gas leakage in the engine compartment, reduced performance, increased fuel consumption, and potential safety hazards.
LED Light Base Die Casting Parts
1. Test area: Sealing performance of the entire die casting part.
2. Function: Prevent reduced waterproof performance of LED lights caused by poor sealing, avoiding moisture ingress.
3. High sealing requirement: Outdoor environments require proper sealing to prevent water ingress, oxidation, and corrosion.
4. Safety impact: Water ingress may cause circuit dampness, leading to leakage, short circuits, or even fire hazards.
