EMMKAY INDUSTRIES manufactures precision pharmaceutical tablet dies and punches for rotary tablet press machines used in pharmaceutical production. Since 1983, we have supplied high-quality tooling with full material traceability to pharmaceutical companies across India and internationally.
Pharmaceutical tablet manufacturing demands the highest standards of precision, material quality, and regulatory compliance. Every tablet die and punch we produce meets strict dimensional tolerances, surface finish requirements, and material traceability standards required by pharmaceutical regulatory bodies.

Tooling for Common Pharmaceutical Formulation Challenges
Different drug formulations place different demands on tablet tooling. India's pharmaceutical industry produces over 60,000 generic drug formulations, each with unique compression characteristics. Here is how we address the most common challenges:
Sticking and Picking
Common in: Ibuprofen, acetaminophen, aspirin, and hygroscopic APIs
DLC-coated punch tips (friction coefficient 0.05-0.1) combined with mirror-polished surfaces (Ra below 0.1 μm). DLC coating reduces sticking by up to 90% compared to uncoated tooling. Learn more →
Abrasive Wear
Common in: Calcium carbonate, iron supplements, mineral-based excipients
HCHC (D3) steel dies and punches (62-64 HRC) with TiN coating. HCHC tooling lasts 3-5x longer than OHNS in abrasive formulations, and TiN coating adds another 2-3x life extension. Learn more →
Capping and Lamination
Common in: High-dose tablets, poorly compressible APIs, low-moisture granulations
Tapered dies with polished bores to reduce ejection stress. Pre-compression on the press combined with optimized punch tip geometry (shallow concave with beveled edge) reduces air entrapment. Learn more →
Corrosion
Common in: Effervescent tablets, acidic APIs, chloride-containing excipients
EMMKAY Special Steel or S7 steel with CrN coating. For effervescent tablets, we recommend stainless steel dies with CrN-coated punches to resist citric and tartaric acid attack. Learn more →
Quality and Compliance
Pharmaceutical tablet manufacturing in India is regulated by CDSCO and must comply with Schedule M of the Drugs and Cosmetics Act. While tooling itself is not directly regulated, the quality of your tooling directly impacts tablet quality attributes that are tested during batch release — weight uniformity, hardness, friability, disintegration, and dissolution.
Material Traceability
We provide material test certificates for every steel grade used. Each batch of tooling can be traced back to the raw material lot — supporting your facility's documentation requirements for WHO GMP, Schedule M, and FDA audits.
Dimensional Inspection
Every tooling set is inspected for critical dimensions: punch length uniformity (±0.005mm), die bore diameter (±0.01mm), tip diameter, cup depth, and head flat thickness. Inspection reports are available on request.
Surface Finish Verification
Punch tip surfaces are polished to Ra 0.05-0.2 μm depending on the application. Surface roughness is verified using calibrated profilometers. Smoother surfaces reduce sticking and produce better-looking tablets.
Hardness Testing
Every punch and die is hardness-tested after heat treatment. OHNS: 58-62 HRC, HCHC: 62-64 HRC, S7: 54-58 HRC. Hardness reports are included with pharmaceutical orders on request.
