From Start-Up to Stable Output: On-Site Lessons from Two Pharma Plants
Share
Introduction: After equipment lands on the shop floor, most teams go through “ramp-up → stabilize → optimize.” The common goal: reach stable, compliant throughput with minimal trial cost.

Frequently Asked Questions
Q: How does laser drilling create controlled-release tablets?
A: Laser drilling creates a precise aperture in the tablet coating, forming the drug delivery orifice for osmotic pump tablet systems (OROS technology). The osmotic pressure differential between the tablet core and gastrointestinal fluids drives API release through this aperture at a controlled rate. Hole diameter, depth (blind vs. through-hole), and position are critical parameters. The Olando K3-2 offers ±0.1 mm accuracy and up to 120,000 tablets/hour (based on a 15 mm tablet), with closed-loop vision inspection.
Q: Can the Olando K3-2 drill blind holes and through-holes?
A: Yes — the Olando K3-2 offers 0.9 mm blind/through-hole precision with ±0.05 mm hole depth consistency.
Q: What tablet shapes and sizes can the Olando K3-2 process?
A: The Olando K3-2 handles bilayer round tablets. Supported tablet diameters range from 6 mm to 20 mm. The system processes up to 120,000 tablets/hour (based on a 15 mm tablet).
Q: Is the laser drilling system designed to support FDA 21 CFR Part 11 requirements?
A: The Olando K3-2 Laser Drilling System is designed for cGMP environments, uses a Siemens PLC, and is designed to support 21 CFR Part 11 compliance (audit trail, electronic records, access control). For a full Part 11 workflow (final compliance is established by the end user's own validation), integrate the system's data outputs into a validated manufacturing execution system (MES). Reference customers include Shanghai Modern Pharmaceutical (12 installed units for Nifedipine CR) and Shanghai Xinyi Pharmaceutical (3 units for Doxazosin Mesylate).

Q: What are the ongoing maintenance requirements for laser drilling equipment?
A: Key maintenance items for the Olando K3-2: Preventive maintenance should be incorporated into your equipment qualification protocol (IQ/OQ/PQ). Request our service agreement terms.
