Improving Capsule De-Molding and avoiding De-shaping

Smooth Release. Zero Rejection. Hallmark Pinbars in Action.

De-Molding: The Critical Last Step That Defines Quality

In capsule manufacturing, precision doesn’t end at shaping—it extends to the seamless release of each capsule shell from the tooling surface. As the MRFR reports outline, capsule rejections due to deformation, sticking, or tearing are an issue—especially with HPMC and other plant-based materials.

De-molding and de-shaping means more than wastage—it causes production slowdowns, increases operator intervention, and affects downstream filling and sealing.

That’s why Hallmark Pinbars are engineered to form perfectly shaped capsules and facilitate its release with equal precision.

The Hallmark Surface Engineering Advantage

We’ve redefined de-molding with advanced surface finishes and proprietary coatings that deliver superior release characteristics for both gelatin and HPMC capsules.

Here’s how we do it:

 

• Mirror-Finish Polishing: Achieved through ultra-fine grinding and micro-finishing techniques, it reduces surface friction and capsule sticking.
• Optimized Taper Geometry: Designed to customize raw material pick-up from dipping tanks for uniform wall thickness after drying and natural shrinkage, especially for HPMC shells prone to post-dry expansion.
• Anti-Adhesion Surface Treatment: Optional proprietary coatings applied to pinbar surfaces reduce adhesion without affecting capsule clarity or formulation compatibility.

 

The result? Capsules detach cleanly and retain their dimensional integrity—no cracks, no snags.

Benefits for Manufacturers

With Hallmark’s advance-release pinbars, manufacturers experience:

 

• Reduced Capsule Rejection Rates
• Higher Line Efficiency on De-Molding Stations
• Lower Cleaning Frequency Between Batches
• Improved Shell Consistency and Visual Appeal

 

This performance is critical for plants running multi-shift operations or producing premium capsules where aesthetics are non-negotiable.

Compatible with Modern & Legacy Equipment

Whether you’re using a legacy line with manual ejection or a fully automated capsule former, Hallmark Pinbars are designed to integrate smoothly. Our surface finishes and geometries are customized based on machine speed, capsule material, and drying method.

Our engineers collaborate directly with your operations team to ensure every pinbar is tailored to your production environment and process tolerances.

Final Thought

Pinbar is more than just forming capsules. At Hallmark, we invest and engineer in that precise craftsmanship, that performs noiselessly for years, as efficiently as on its first day at work.

Every clean release is a step toward flawless production.

Fewer stoppages. Fewer rejections. More productivity.
