Medical and pharmaceutical parts demand precision, repeatability and clean, low-contamination production — small tolerances and consistent quality matter more than in almost any other application.
The absence of hydraulic oil is key: no aerosols, no leaks, no risk of oil contaminating the mold or part. That is why JSW all-electric machines are routinely installed in ISO Class 7 and 8 cleanrooms. Each axis is servo-driven with an absolute encoder, holding 0.01 mm repeatability at CNC level — essential for connectors, syringe plungers and multi-cavity diagnostic parts where shot-to-shot consistency is critical. We cover precision in more detail in Why JSW machines are the standard for automotive and medical molding.
Beyond a clean drive, quality depends on stable melt temperature and process control. Tool-Temp units provide the precise control pharmaceutical and chemical production requires, while S.I.S.E. hot runner controllers manage zones on precision medical tooling. Star Automation cartesian robots enable clean, repeatable part handling with no human contact with the part. On material changes, purging compounds reduce the risk of black specks and contamination.

An all-electric drive has no hydraulic oil, so there are no aerosols or leaks to contaminate the part or environment. That is why JSW machines are routinely installed in ISO Class 7 and 8 cleanrooms, with the 0.01 mm precision that medical and diagnostic components require.
Through a combination of clean oil-free drive, controlled melt temperature and regular barrel cleaning. On material or color changes, purging compounds remove residual material and degraded deposits before they reach the part.
