01 / Injection Moulding

Arburg Allrounder Comfort A series. All-electric, hydraulic-free.

The Allrounder Comfort A is Arburg's all-electric workhorse. Replacing hydraulic actuation with servo-electric drives eliminates the largest contamination vector in conventional injection moulding: hydraulic oil mist that drifts from the press into the bottle as it's being moulded.

The Gestica controller runs Arburg's Fill Assist: a live digital twin of every shot that holds mass inside ±0.01 g, compensates for batch-to-batch polymer viscosity drift automatically, and flags any deviation from the modelled fill pattern in real time. Sample-bottle threads, necks, and seal surfaces come off the press dimensionally identical, shift after shift.

02 / Stretch Blow Moulding

Aoki single-stage ISBM. Preform and bottle in one cycle.

Aoki's injection stretch blow moulding (ISBM) machinery is the Japanese gold standard for clear-PET sample-bottle production. Unlike two-stage blow moulding, where preforms are produced, stored, transported, and re-heated, Aoki's single-stage process forms and blows the bottle in one thermal pass.

The advantage for fluid analysis: the bottle interior never encounters open air between forming stages, never sits in storage where dust accumulates, and never re-heats in a cycle that risks plasticiser migration. The result is crystal-clear PET containers with particle-mitigated interiors straight off the press.

03 / Thermal Conditioning

A specialised Hot Process line.

Fluid samples are often drawn hot. A sampler valve on a haul truck, a turbine bearing housing, a compressor crankcase. These can all extract fluid at 60–90 °C. A sample bottle that softens, deforms, or leaches plasticiser at that temperature compromises every downstream analytical reading.

Our specialised Hot Process is a thermal conditioning stage applied immediately after Aoki ISBM. It cross-tunes the PET crystallinity so the finished bottle retains dimensional stability and chemical inertness at hot fluid extraction temperature, without compromising clarity or seal-surface integrity. The conditioning stage runs at a verified 100 °C through HB-Therm closed-loop temperature control across the production cycle.

04 / In-Line Capping

Kinex in-line capper. Sealed before the bottle ever sees air.

Atmospheric purity is only as good as the moment the closure goes on. A bottle that's been moulded, conditioned, and inspected, and then sits open on a packing bench for ten minutes, has lost every contamination guarantee the earlier stages bought.

Fluid Science seals each bottle on the production line itself with a Kinex Cappers in-line capping system. At a verified 62 caps per minute, with closed-loop torque, presence detection, and cap-reject diagnostics on every cycle, the interior of every Fluid Science bottle is sealed within seconds of leaving the Hot Process stage.

The result: a bottle whose interior atmosphere is the ultra-low particulate, oil-free Class 0 air of the Aoki blow station. Not the warehouse, not the packing room, not the courier truck.

05 / Packaging & Branding

HP Latex R530. Digital CNC box cutter. In-house, on-site.

The integrity story doesn't stop at the bottle. Sample kits (a custom-printed box, a foam insert, an instruction card, a return label) usually involve three or four outside vendors and a tooling lead time of weeks.

Fluid Science brings the entire kit-packaging stack in-house. The HP Latex R530 rigid-and-flexible printer produces full-colour, oil-resistant, food-grade-rated branding on board stock up to 64" wide. Our digital CNC box cutter then forms the box geometry. Any geometry, no tooling required.

The practical result is a manufacturer that carries your brand all the way through the chain of custody. Every kit we ship can be produced in the customer's own livery (corporate colours, logo lock-ups, application-specific iconography, regulatory marks, even bilingual or multi-region label artwork), with no minimum order quantity and zero tooling charge. Whether you are an oil blender, a mining house, a fleet operator, a marine surveyor, or an independent inspection agency, the box your customer opens is unmistakably yours.

Box geometry is just as open. Our 12-bottle and 20-bottle kits are the workhorse configurations, but because every box is digitally cut, custom geometries (single-vial mailers, 6-pack starter kits, large-format on-site sampling crates, hard-case field kits with foam inserts) are produced from the same digital workflow with no die-board lead time. Need 50 prototype kits for a pilot fleet this month, then 5,000 production kits per month for a national network the next? The artwork-to-dispatch cycle stays under a week, end to end.

PACKAGING

The Ultra Clean Protocol

Four engineered guarantees, one absolute standard.

The Ultra Clean Protocol is the compliance specification all Fluid Science sample-grade plastics are produced to. It is the contractual integrity baseline we hold the manufacturing line to, every shift, every shot.

Zero-Contamination Foundation

All-electric Arburg Allrounder Comfort A. No hydraulic fluid in the press cell. Gestica controllers run a Fill Assist digital twin of every injection cycle, holding shot mass inside ±0.01 g.

Atmospheric Integrity
