WORLD CLASS PINBARS
Designed for Demanding Capsule Production
Capsule manufacturing places exceptional demands on pinbar performance, particularly as processes move toward clear and transparent (CT) shells, tighter tolerances, and more challenging formulations such as HPMC. To meet these evolving requirements, our Special hardened pinbars offer a refined working surface engineered for consistency, durability, and long-term reliability.
Advanced Surface Engineering
The Special pinbars are manufactured from hardened stainless steel and finished with a precision plating layer of 2-3 microns. This engineered surface achieves a working hardness in the range of 65–70 HRC, compared to the 32–38 HRC typically seen in work-hardened SS304 pinbars.
The result is a surface that retains dimensional integrity over extended operating cycles, even under continuous stripping and high-speed production conditions.to multiple Industries.
Low Friction for Cleaner
De-Moulding
The hardened & plated surface exhibits an extremely low coefficient of friction, significantly reducing interaction forces during de-moulding. This minimizes surface scratches caused by metal strippers and supports smoother capsule release.
This characteristic is particularly beneficial for:
- Clear and transparent capsules (CT)
- HPMC capsules, which are inherently more adhesive during stripping
Extended Scratch Free Life
Usable pinbar life is defined by surface wear, measured through Ra (surface roughness) values, where a range of < 0.1 Ra is critical for consistent capsule quality.
Field performance shows that Special hardened pinbars maintain acceptable Ra levels for up to 7X longer than standard pinbars, resulting in:
- Reduced replacement frequency
- Stable capsule quality over extended production periods
- Lower long-term operational interruptions
Consistency that Supports Precision Fit
Sustained surface smoothness and dimensional stability directly contribute to:
- Uniform shell formation
- Reliable cap–body fitment
- Consistent performance over years of operation
This is especially valuable where precision fit, aesthetics, and repeatability are critical to brand and process integrity.
Designed for Performance,
Built for Longevity
While standard SS304 pinbars remain a proven and widely used solution, Special hardened pinbars provide an enhanced performance for manufacturers seeking uncompromising durability, improved de-moulding behavior, and long-term consistency—particularly in advanced and demanding capsule applications.
