EMMKAY INDUSTRIES manufactures specialized tablet dies and punches for ayurvedic and herbal tablet production. Since 1983, we have worked with ayurvedic manufacturers across India to develop tooling solutions that handle the unique challenges of herbal formulations.
Ayurvedic tablet manufacturing is fundamentally different from pharmaceutical production. Herbal formulations contain plant extracts, gums, resins, and natural binders that are stickier, more abrasive, and more corrosive than synthetic pharmaceutical ingredients. Our tooling is specifically designed to overcome these challenges.
Challenges of Ayurvedic Tablet Manufacturing
Sticking and Picking
Herbal extracts contain natural sugars, gums, and resins that stick to punch faces. Standard chrome-plated punches often fail within days with sticky ayurvedic formulations.
Corrosion
Many ayurvedic ingredients are acidic or contain moisture-attracting compounds. Amla (Indian gooseberry) is highly acidic and corrodes standard tool steel rapidly.
Abrasion
Herbal powders often contain silica, calcium, and mineral compounds that are highly abrasive, wearing down punch tips and die bores faster than typical pharmaceutical excipients.
Inconsistent Granulation
Ayurvedic granules tend to be less uniform than pharmaceutical granules, leading to weight variation, capping, and lamination problems.

| HCHC + CrN Coating | Mildly corrosive formulations | Wear resistance + corrosion protection |
| Shallow concave tips | All sticky ayurvedic formulations | Reduces sticking vs. deep concave designs |
| Tapered die bores | Sticky formulations | Improves tablet ejection |
Frequently Asked Questions
Why do my ayurvedic tablets stick to the punches?
Sticking in ayurvedic tablets is caused by natural sugars, gums, and resins in herbal extracts. Solutions include DLC-coated punches, mirror-polished punch tips, shallow concave punch geometry, and optimizing your formulation's moisture content and lubricant levels.
Which coating is best for ayurvedic tablet tooling?
DLC (Diamond-Like Carbon) coating is the best option for sticky ayurvedic formulations. It provides the lowest friction surface and dramatically reduces sticking. For moderately sticky formulations, chrome plating with mirror polish is a cost-effective alternative.
How long does ayurvedic tablet tooling last?
Standard OHNS tooling may last 1–3 million tablets with herbal formulations. DLC-coated HCHC tooling can extend this to 3–5 million tablets. Proper cleaning after every batch is essential.
Can you make tooling for large ayurvedic vati tablets?
Yes. We manufacture tooling for ayurvedic vati tablets up to 25mm diameter. Large flat-faced round punches are our most common ayurvedic tooling configuration.
