Sterile Integrity & Cleanroom Compatibility

In the world of medical healthcare, microbial contamination is a non-negotiable failure. Our One-Step ISBM machines are designed specifically for Cleanroom Class 10,000 (ISO 7) or Class 100,000 (ISO 8) operations. Because the preform never leaves the machine and is immediately blown into its final shape using filtered high-pressure air, the risk of airborne particulates or human-borne bacteria entering the container is virtually eliminated. This is particularly vital for eye drop bottles where the interior must remain completely sterile before the aseptic filling process begins. The compact vertical design of our units ensures that you maximize your square footage, reducing the operational costs of maintaining large-scale sterile zones.

Unrivaled Neck and Thread Precision

Pharmaceutical containers rely heavily on the accuracy of the neck finish to ensure a perfect seal with child-resistant closures (CRC) and tamper-evident caps. Our injection-moulded neck technology ensures that dimensions are held to tolerances within 0.05mm. Unlike traditional extrusion blow moulding (EBM), the One-Step ISBM process creates a perfectly smooth, flash-free neck. This eliminates the need for post-production trimming or reaming, which often introduces plastic dust into the bottle. For liquid medications like syrups or volatile chemical reagents, this precision prevents leakage during shipping and ensures the integrity of the medication throughout its entire shelf life in UK pharmacies.

Superior Aesthetics and Wall Distribution

The biaxial orientation achieved in the stretch-blow phase significantly enhances the clarity and impact resistance of PET and PP materials. Pharmaceutical brands often require containers that allow patients to clearly see the dosage levels or the color of the medication. Our technology ensures uniform wall thickness distribution, which prevents weak spots in the corners of square or rectangular pill bottles. This structural uniformity allows for lightweighting of the container—reducing material usage by up to 15% without sacrificing strength. In the context of the UK’s Plastic Packaging Tax, this material efficiency translates directly into better profit margins for manufacturers.

Bespoke Solutions for Regional UK Manufacturers: Whether you are a boutique lab in Cambridge or a large-scale contract manufacturer in the Midlands, Ever Power provides localized support. We understand that UK regulations require strict validation (IQ/OQ/PQ), and our engineering team provides full documentation support to ensure your equipment is ready for MHRA inspections.

The Challenge: A major supplier of liquid nasal sprays in Hampshire was struggling with a 4% rejection rate due to inconsistent neck threading and flash issues from an aging EBM (Extrusion Blow Moulding) line. The manual trimming process was introducing micro-plastic particles into their Class 7 cleanroom, necessitating frequent shutdowns for cleaning.

The Solution: Ever Power installed a customized 4-cavity One-Step ISBM machine featuring a full servo-electric drive. We developed a bespoke mould that integrated the nasal spray’s unique pump-housing dimensions directly into the injection phase of the preform.

The Result: The client saw an immediate reduction in rejection rates to less than 0.1%. Energy consumption dropped by 30% because the reheating stage was eliminated. Most importantly, the elimination of post-process trimming allowed them to increase their production uptime by 15%.
