ALLPACK INDONESIA 2025 is over

We are back from the 24th International Exhibition on Processing, Packaging, Automation, Handling for Food & Beverage, Pharmaceutical and Cosmetic

ALLPACK INDONESIA 2025 is one of Southeast Asia’s leading international exhibitions focused on processing, packaging, automation, and handling technologies for the food & beverage, pharmaceutical, cosmetic, and personal care industries.

Throughout the event, our team held numerous valuable meetings with customers and partners, strengthening existing relationships and exploring new opportunities for collaboration.

We were delighted to join forces with our trusted partner Rieckermann Indonesia, who ensured a perfectly prepared booth and seamless organisation of the event. Their professionalism and attention to detail created the ideal setting for productive discussions and meaningful connections.

Thank you to everyone who visited us during AllPack — we look forward to continuing our conversations and building on the momentum from this successful exhibition.

Ejection Forces – Among the Most Important Tablet Press Parameters

Ejection force is a critical factor in tablet compression, directly affecting product quality, tooling wear, and the risk of other defects. It represents the resistance when the lower punch pushes the tablet out of the die, influenced by friction, lubrication, geometry, compaction pressure, and speed.

• When forces rise? High compaction pressure, fast press speed, poor lubrication, worn tooling, or large tablet diameter.
• How to reduce them? Optimise lubrication, use tapered/polished dies, maintain tooling sharpness, and monitor die bore wear.

ADAMUS SA supports customers with proper force calculations and provides specialised punches and dies — including advanced coatings — to effectively reduce ejection forces and extend tooling longevity.

Case Study – Tablet Compression Optimisation with Adamus S.A.

Client’s problem

• The pharmaceutical manufacturer was producing oval tablets with deep engravings.
• Tablets often showed defects such as capping, edge chipping, and breakage.
• To reduce rejects, the press had to run at a slower speed, which lowered productivity.
• Frequent sticking of powder to punches caused downtime for cleaning.

Adamus SA analysis

Adamus SA engineers carried out a full process and tooling audit:

• Found that the engraving geometry was too sharp, creating stress points in the tablets.
• Identified that the punch surface finish was not optimised, which increased friction and sticking.
• Compression parameters were tuned for speed, but not for quality balance.

Implemented Solution

1. Tablet and Tooling Redesign

• Modified engraving depth and radii to distribute compression forces more evenly.
• Adjusted die geometry to improve air release and reduce lamination risk.

2. Protective Coatings

Applied DLC (diamond-like carbon) coating to punches, which:

• Reduced friction,
• Minimised sticking,
• Increased wear and corrosion resistance.

3. Process Optimisation

• Adjusted compression force and dwell time for more stable compaction.
• Introduced a preventive maintenance and cleaning schedule for tooling.

Results

• Reject rate reduced by over 70%.
• Line productivity increased by 20%, as the press could run faster without quality loss.
• Downtime decreased significantly thanks to reduced sticking and longer punch life.
• Improved tablet quality – engravings were sharper and edges more consistent.

Key Takeaways

• Even small changes in tablet geometry and tooling design can dramatically improve process stability.
• Advanced coatings (DLC, TiN, CrN) are essential in combating sticking and extending tool life.
• Adamus acts not just as a tooling supplier but as a technology partner, combining CAD design, material science, and process consulting to optimise pharmaceutical production.
