Hardness Auditing
Hardened H13 cores undergo Rockwell hardness tests to confirm 48-52 HRC levels, ensuring maximum friction resistance.

About
Over two decades of excellence in toolroom engineering and packaging mould designs.
Established Toolroom
Precision Toolroom Engineering Since 2005
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.
Our Commitment to Quality & Tolerances
Every mould block goes through detailed inspections to confirm dimensions, alignment, and water flow.
Pressure Tested Leak Checks
Cooling tracks are pressure checked at 8 bar for 12 hours to verify leak-free cooling operations.
Micrometer Calibrations
We inspect core concentricity using digital dial indicators to verify wall thickness consistency.
Our Core Toolroom Strengths
BISHNU MOULDS delivers engineering precision and prompt trial responses to maintain long-term production client relations.
1
In-House SolidWorks Modeling
Tool designers work directly with machining heads to ensure parting lines match lathe and VMC coordinates perfectly.
2
VMC Milling Accuracy
High-speed vertical milling machining centers run PowerMill paths to cut steel cavities down to 10 microns.
Client Relations
Long-Term Support & Digital Spare Parts Archiving
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.
