Hardness Auditing
Hardened H13 cores undergo Rockwell hardness tests to confirm 48-52 HRC levels, ensuring maximum friction resistance.
Over two decades of excellence in toolroom engineering and packaging mould designs.
Founded as a specialized packaging tool room in Vasai, Palghar, BISHNU MOULDS has earned a reputation for precision blow moulds and high-cavitation injection tooling. We specialize in engineering solutions for heavy-duty lubricants, agrochemicals, food jars, and cosmetics containers.
Our mission is to help packaging manufacturers reduce blow cycle times, extend mould lifespans, and eliminate container leakage by implementing high-tolerance tool shapes, quality steels, and flow simulation checks.
Every mould block goes through detailed inspections to confirm dimensions, alignment, and water flow.
Hardened H13 cores undergo Rockwell hardness tests to confirm 48-52 HRC levels, ensuring maximum friction resistance.
Cooling tracks are pressure checked at 8 bar for 12 hours to verify leak-free cooling operations.
We inspect core concentricity using digital dial indicators to verify wall thickness consistency.
BISHNU MOULDS delivers engineering precision and prompt trial responses to maintain long-term production client relations.
Tool designers work directly with machining heads to ensure parting lines match lathe and VMC coordinates perfectly.
High-speed vertical milling machining centers run PowerMill paths to cut steel cavities down to 10 microns.
A mould tool is a long-term production asset. We maintain a secure digital archive of all 3D CAD/CAM models. If you require replacement neck rings, blow pins, core sliders, or ejector elements, we can manufacture exact replacements within 48 hours.
Our engineers also assist with on-site trials and mould maintenance advice to ensure your packaging production lines run with minimal downtime.
