company news about What is the Importance of 100% Water Pressure Testing for Certain Printing Machine Components？

100% water pressure testing is vital for printing machine components that manage the flow of water, coolant, or hydraulic fluid. This non-destructive test verifies the integrity of a part by subjecting it to pressurized water to detect any leaks, cracks, or porosity in the casting that are not visible to the naked eye. It ensures the part will not fail under operational pressure.

The failure of a single, seemingly minor component like a water pump housing or a coolant line manifold can lead to major press stoppages and internal damage. Leaking water can mix with ink, ruin electronics, and cause corrosion. The pain point for buyers is that internal casting defects are impossible to detect without specialized testing. Many suppliers skip 100% pressure testing to save time and money, opting instead for random sampling, which carries a high risk of a defective part slipping through and causing a failure in the field.

FIRST Printing Machine Accessory Factory incorporates 100% water pressure testing as a non-negotiable step in our fourth inspection stage for all relevant components. After machining and ultrasonic cleaning, parts like manifolds and certain housings are tested to ensure they are completely sealed and free from internal flaws. This commitment to 100% testing, rather than sampling, is a core part of our quality promise. It eliminates the risk of field failure due to latent defects, giving our global clients absolute confidence in the reliability and safety of the parts they install on their Heidelberg, KBA, or Komori presses.

For critical fluid-handling components, "good enough" is not enough. A failure can be catastrophic. FIRST's policy of 100% water pressure testing provides the definitive quality assurance that professional printers need to run their operations with peace of mind.
