What is the difference between the Z Series and a fully electric machine?

The Z Series is servo-hydraulic: a servo pump drives the hydraulics, which then move the clamp and injection units. A fully electric machine has no hydraulic circuit at all — every axis is driven directly by a servo motor. Electric wins on energy efficiency, noise and repeatability at low to medium tonnage. Servo-hydraulic wins on purchase price and on clamp force per square metre of floor space above roughly 4,500 kN, which is why the Z Series extends to 29,000 kN while all-electric machines in this class do not.

What do the A / B / C / D screw options mean?

They are different screw diameters available for the same machine, which lets you trade shot weight against injection pressure. A is the largest diameter and lowest pressure, giving the maximum shot weight; D is the smallest and highest pressure, suited to thin-wall and high-precision work. Choosing correctly matters: an oversized screw gives poor plasticising, an undersized one limits shot weight.

Which Z Series model should I choose for PET bottles?

For standard PET packaging we recommend the Z-PET series rather than a standard Z machine. Z-PET models have a longer L/D ratio (24 to 26), a higher pump pressure of 16 MPa for injection through the preform neck, and a plasticising servo motor option. They cover 2,700 to 5,200 kN clamp with injection units from 1,400 g up to 11,000 g, suitable for mineral water, beverage, edible oil and household chemical bottles.

What testing is done before delivery?

Every machine runs more than 72 hours of continuous reliability testing before delivery, with each key component recorded during that run. Third-party inspection is available on request, and you are welcome to send your own inspector.

Can I get a machine sized for my part?

Yes, and that is the right way to buy. Send the part drawing or the finished part weight, the resin and your annual volume, and we will calculate the clamping force from the projected area, then confirm which model and which screw configuration fits. Clamping force is calculated against your part rather than rounded up to the next frame.

Z Series Servo Injection Molding Machines — 1,100 to 29,000 kN

01

The range at a glance

Four model families covering 1,100 to 29,000 kN

The Z Series is split into four families by clamping force. Within each family, every model offers three or four screw configurations — the same machine can be set up for a 2,600 g shot at low pressure or a 3,500 g shot at high pressure, depending on the part.

Family	Clamping force	Models	Typical applications
ZX110 – ZX270	1,100 – 2,700 kN	5	General plastics, small components, thin-wall packaging
ZX318 – ZX650	3,180 – 6,500 kN	5	General and engineering plastics, crates, buckets, automotive parts
Z700 – Z1300	7,000 – 13,000 kN	5	Large structural parts, pallets, thick-wall containers
Z1400 – Z2900	15,000 – 29,000 kN	5	Large automotive, heavy-duty packaging, thick structural parts
Z-PET series	2,700 – 5,200 kN	4 (9 variants)	PET preforms and bottles — mineral water, beverage, edible oil, household chemical

Clamping force listed in kN. Divide by 9.81 for the tonnage equivalent — a Z1500 is roughly 1,500 tons. Machine selection should start from your part's projected area, not from a model name — see our machine sizing guide for the calculation.

02

Z Series or LX all-electric?

Two series, and the honest answer on which one you need

These are not competing products at the same end of the market — they cover different needs. Here is where each one is genuinely the better answer.

Z Series — servo-hydraulic

1,100 – 29,000 kN

Best for large tonnage, large parts, thick walls
Clamp force per square metre of floor is the strongest here — a 29,000 kN machine in all-electric form does not exist in this class
Lower purchase price per unit of clamp force
Servo pump delivers power on demand, so it is considerably more efficient than a conventional hydraulic machine
Reaches 29,000 kN; the all-electric range stops at 4,500 kN

Z-PET series — PET packaging specialist

2,700 – 5,200 kN · up to 11,000 g shot

Built for preforms and bottles, not a general machine with a PET setting
Higher pump pressure — 16 MPa — to inject through the preform neck
Longer L/D ratio, 24 to 26, for thorough PET plasticising
Plasticising servo motor optional, for cycle time where it matters
Larger injection units available on request beyond the standard range

LX Series — all-electric

50 – 4,500 kN

Best for precision parts, medical and optical, where repeatability is the priority
No hydraulic oil at all — quieter, cleaner, lower maintenance
±0.01 mm repeatability, CODESYS control over EtherCAT
50–80% lower energy use versus a comparable hydraulic machine
See the LX series page for the full range

Which one to buy

Our honest recommendation

Above 4,500 kN — Z Series. There is no all-electric alternative in this class.
Thick walls or large parts — Z Series. Servo-hydraulic handles the tonnage more economically.
PET bottles and preforms — Z-PET. Not a general machine adapted.
Tight tolerance, medical or optical — LX all-electric.
Not sure — send the part. We will tell you which side of that line you are on, and if a smaller machine will do the job we will say that too.

03

What is actually built into the machine

Four design points that determine how it performs

Servo energy-saving drive

A servo pump system fitted across the range delivers power on demand rather than running continuously. It cuts energy consumption considerably compared with a fixed-displacement hydraulic machine of the same size, without the purchase premium of a fully electric machine.

Optimised clamping structure

A one-piece linkage structure with high-quality copper bushes combines clamping rigidity and accuracy. This is what keeps platen parallelism within tolerance over years, and it is why platen parallelism on a used Z machine is worth checking on inspection.

Stable injection quality

The injection carriage uses an integral copper sleeve, giving stable plasticising and repeatable shot accuracy. Shot consistency is what determines dimensional consistency on the part, so this detail matters more than it sounds.

Multiple screw options

Each model offers A / B / C / D screw diameters, letting you balance shot weight against process pressure for the parts you actually run. This is the feature that lets one machine cover a product range instead of forcing a compromise on the screw.

04

Standard and optional configuration

What comes as standard, and what can be added

Standard configuration	Why it matters in production
Double-cylinder injection unit with injection-end cushion control	Stable cushion means stable shot weight, which means stable dimensions
High-performance flow-type injection structure, low-inertia carriage	Faster response and less energy per shot
Four-stage large-flow cartridge valve clamping system	Clamping force stays stable across the whole mould thickness range
Automatic mould height adjustment	Changeover without manual re-setting, fewer setup errors
Core pull, unscrewing, special nozzle, multi-point ejection reserved	Capability to add features later without replacing the machine
Bi-metal barrel with precision screw and IR melt temperature sensing	Wear resistance plus accurate melt temperature control
Automatic cooling water temperature control with alarm	Stable mould temperature, which is half of warpage control
Centralised lubrication with oil starvation alarm	Prevents the bearing damage that comes from running dry
PLC + TFT true-colour control, 60 mould parameter memory	Recall settings per mould rather than relying on someone remembering
Temperature deviation display, screw cold-start protection, electronic mould scale protection	Protects both machine and mould when something goes wrong

Optional configuration

Optional	When it is worth adding
PID multi-stage cavity / holding pressure control	Tight dimensional requirements, or a product with heavy thick-to-thin variation
Insulation plates and quick mould change device	High changeover frequency — the saving is in setup time
Robot, conveyor and automation interface with line control	Unattended running, or where labour is the constraint
Hopper dryer and dehumidifying conveying system	Any hygroscopic resin — see the drying guide
Servo plasticising motor, bi-alloy screw upgrade	Cycle time where recovery is the bottleneck, or abrasive resins
Corrosion / heat resistant screw and barrel sets	PVC, flame-retardant grades, engineering plastics
Oil temperature cooling and heating unit	Process control where melt temperature stability matters
Water manifold, low-pressure mould protection, automatic lubrication	Mould protection where a low-pressure mould is fitted
SPC and network data management interface	Where you need process data traceable to a customer requirement
Customised configurations for preforms, caps and thin-wall parts	When the standard configuration will not hold the target cycle

Suitable for PET packaging products such as mineral water, beverage, edible oil and household chemical bottles. Larger injection unit sizes are available on request. The 16 MPa pump pressure is what allows injection through the preform neck — this is the specific reason a standard Z machine is the wrong choice for PET, and it is also why drying is non-negotiable in PET work. See our drying guide for the PET drying cycle.

Specifications subject to change without notice. Injection weight is given for PS unless marked otherwise. Shot volume is theoretical. Values depend on the screw configuration shown — each figure above corresponds to the configuration in the same position.

How to order — and what to send

Machine size is calculated from your part, not chosen from a list

1 · Send the requirement

Part drawing or finished part weight, resin, annual volume, target cycle, destination port. For PET, the bottle size and preform weight.

2 · We size and specify

Clamping force calculated from your projected area, and the screw configuration chosen against your shot weight and required pressure — not rounded up to the biggest option.

3 · Quotation and confirmation

Machine model, screw configuration, standard and optional configuration, price, lead time and shipping terms — all in writing before anything starts.

4 · Production and testing

Manufacture, then more than 72 hours of continuous reliability testing with each key component recorded. Third-party inspection available at this stage.

5 · Delivery

Export packing, FOB or CIF to your port, documentation and tracking sent before the container departs.

6 · After-sales

Technical support on commissioning, spare parts supply, and wear parts matched to the screw configuration we fitted.

Not sure which series? Send the part and the resin. If your part is a precision component needing tight tolerance, the LX all-electric range may be the better answer — if it is large, thick-walled, or above 4,500 kN, it is certainly the Z Series. We will tell you which, including when that means selling you a smaller machine than you asked about.

Our commitments on the Z Series

Machine size is calculated from your part's projected area at the required filling pressure, with a safety factor — not rounded up to the next frame. Screw configuration is specified against your shot weight and resin rather than supplied as a default. Every machine runs more than 72 hours of continuous reliability testing before delivery, with each key component recorded. Third-party inspection is available on request, and you are welcome to send your own inspector.
