เครื่องฉีดขึ้นรูปพลาสติกแบบเป่า EP-ZQ60

The 45 or 50 mm screw delivers a precisely metered shot — up to 383 g — through the hot-runner system into the injection mould surrounding the core pins. Each bottle’s neck finish, thread form, and body preform are shaped in a single clamped injection. The 600 KN injection clamp holds the mould shut with a force that prevents flash formation even at maximum cavity count. After cooling, the mould opens and the turntable indexes 120° to Station 2.

The blow mould closes around the warm preforms on the core pins. Compressed air at 0.7–1.2 MPa inflates each preform outward to contact the precisely machined cavity wall. The 100 KN blow clamping force on the EP-ZQ60 maintains mould closure without hydraulic drift. After the programmed cooling dwell, the blow mould opens. All bottles across all cavities have identical wall profiles because they expand to the same steel cavity surface.

At the stripping station the finished, fully-cooled bottles are ejected from the cold rods by the 230 mm stripping mechanism and conveyed onto the discharge belt or directly into a downstream filling line. Because all three stations operate simultaneously, there is no dead time between completed bottle sets — the EP-ZQ60 produces its full cavity output every cycle, continuously.

600 KN injection clamping is 20–30% stronger than what competing machines in the ZQ60 weight class typically offer. This force differential translates directly into longer mould life — fewer re-honing cycles — and consistent neck dimensions across 14-cavity runs without adjustment between shifts. For pharmaceutical buyers running GMP audits, this means fewer caveat findings on container uniformity.

The EP-ZQ60 ships with standard servo rotary indexing as a baseline — not as an option. The high-precision angle divider (which is standard on the ZQ60) synchronises mould open/close with the turntable lift, eliminating the sequential dead time that chain-drive systems introduce. The 4-second dry cycle is the result, and it holds whether the machine is running 5 cavities or 14.

The booster cylinder in the EP-ZQ60’s clamping system does not participate in the mould open/close stroke. It engages only during the hold phase at peak clamp tonnage. Since the hold phase is a small fraction of total cycle time, total energy consumption drops 10–20% compared to conventional architectures where the booster drives every open/close motion. At 37 KW total power, the ZQ60 delivers its output class at genuinely lower utility cost.

A Ho Chi Minh City contract packer supplying a major FMCG brand needed to scale from 200,000 to 700,000 units per month of a 250 ml HDPE hand-wash bottle without adding a second production line. Moving from an EBM platform to two EP-ZQ60 machines running 5-cavity tooling at 250 ml eliminated their scrap-regrind process, reduced per-bottle material cost by approximately 4%, and freed up 40 square metres of floor space previously used for trim waste collection.

An Istanbul pharmaceutical packaging facility running both 30 ml and 100 ml HDPE oral liquid bottles needed a single machine platform that could switch between the two formats within a single shift. The EP-ZQ60 — configured with quick-change mould fixtures — achieved a 12-cavity (30 ml) to 8-cavity (100 ml) changeover in under 45 minutes. Output at both formats consistently passed the EU GMP container-integrity test.

A São Paulo cosmetics OEM producing 50 ml PCTG serum bottles for a Latin American luxury skincare brand needed optical clarity that their previous PP supplier could not consistently deliver. The EP-ZQ60 running PCTG at 10-cavity tooling delivered bottles with haze values below 2% — meeting the EU cosmetics import standard — and maintained consistent weight within ±0.8 g per cycle across a 3-shift day.

A Cairo-based dairy producer entering the functional-drink segment needed 65 ml PS lactic-acid bacterial bottles at 1.5 million units per month. The EP-ZQ60 running 10-cavity PS tooling covered this volume in single-shift operation, with the 22:1 screw providing the melt homogeneity needed for optically clear, stress-craze-resistant PS at commercial speeds. The production team reported zero brittleness failures in transit testing at –18°C.
