The official tonnage-to-model map, the six specification drivers that move the quotation, and the cost lines that never appear on it.

If you have been asked to price a take-out robot for a 200–650 ton injection molding machine and you have come away with three quotations that differ by a wide margin and cannot explain why, you are missing the cost model. A take-out robot in this tonnage band is not a catalogue item you look up a price for — it is a quotation against one of three published model families, and its cost is set by four things: the model class your tonnage forces on you, the reach envelope you need inside the mold, the integration scope you ask for, and the engineering time the supplier commits to after the crate lands.

The NBT take-out robot series: a telescopic vertical column on a floor-mounted base with a long transverse reach beam, built to reach into the open mold of a 200–650 ton injection molding machine. Full model gallery on the TAKE-OUT ROBOT SERIES product page.

This is the framework I walk injection molding automation buyers through at ROBOT (Ningbo) Intelligent Technology Co., Ltd., where my working life is spent on the practical performance of automation equipment rather than on catalogue copy. Our own published specification tables tell you which models carry your tonnage, and I have transcribed the coverage, stroke, reach, payload, take-out time, air consumption and weight below so that you can match quotations against facts instead of adjectives. The photographs of the line we build the cell around are on the take-out robot series page, and our injection molding robot arms category shows where each model sits in the lineup.

How Much Does a Take-Out Robot Cost for a 200–650 Ton Injection Molding Machine?

The honest answer is that a take-out robot for a 200–650 ton injection molding machine is quoted, not listed: the cost is a function of the model family your machine tonnage forces on you and of six specification drivers, and no responsible factory — ours included — publishes a single figure that applies to every configuration in that band. Every product page in our TAKE-OUT ROBOT SERIES catalogue ends with the same three lines: a full specification table, a payment-terms line reading T/T, L/C, PAYPAL, Western Union, and a request for a quotation.

That is not a marketing dodge, and I have watched buyers misread it for years. The same robot arm can cost very different amounts depending on four things:

• The model family your clamping tonnage forces on you. A 200-ton machine and a 650-ton machine sit in different published coverage windows, so we quote them from different families with different reach envelopes, drive platforms and net weights.
• The reach envelope you need inside the mold. Vertical stroke and transverse reach set the structural mass, the actuator class and the servo rating, so they move the quotation further than any cosmetic option.
• The integration scope you ask for. A robot standing alone at the machine, one handing parts to central conveying, and one feeding an in-mold labeling cell are three different scopes of supply, and we never let them be compared as one line.
• The engineering commitment behind the shipment. Commissioning on your floor, operator training, the recommended spares list and the service response afterwards are all part of the real cost of ownership, even when we quote them separately.

Because these four variables are the whole of the cost model, the most useful thing you can do before asking for a price is fix the model from the tonnage and the mold geometry, and then ask every supplier to quote against that identical configuration. A quotation you cannot compare line by line against another quotation is not a saving. It is an open question with a currency symbol attached to it.

Which Take-Out Robot Models Cover a 200–650 Ton Injection Molding Machine?

Three official model families apply to the 200–650 ton band, and the reason is that our published I.M.M. coverage windows overlap rather than tile: the 900 class covers 160–320 ton, the 1100 class covers 250–470 ton, and the 1300W telescopic class covers 380–700 ton. That overlap gives you a real choice of class at most tonnages, but it also means your tonnage alone does not determine your quotation.

Source: ROBOT (Ningbo) published product specification tables for the 3-axis and 5-axis servo robot arms, the telescopic type series and the open-type series. Notation follows the original: 3S denotes the 3-axis configuration and 5D the 5-axis configuration. The SPRE series carries our official line “SUITABLE FOR 90–470T INJECTION MOLDING MACHINE LOAD 6KG”.

Two observations from that table will save you money in the first week. First, our telescopic configuration is faster than the single-stage configuration at the same reach: the published minimum take-out time is 1.5 s on the 900W against 1.8 s on the 900I, and 1.6 s on the 1100W against 2.1 s on the 1100I. Second, the open-type SPRT3S1000W class is the fastest unit in the published range at a 0.7 s minimum take-out time, because it is built for positioning rather than reach, and its 3 kg payload class tells you immediately that it is not a take-out robot in the same sense as the SPRE series.

Because cycle time on this product class is a configuration choice rather than a fixed property — our published figures span 0.7 s to 2.9 s across the same family — a buyer who assumes all take-out robots of a given tonnage perform the same way will size the cell against the wrong number. The published high-speed SPRT3S1200I unit covers 320–530 ton with a 10 kg payload class and a 2.9 s minimum take-out time at a 1000 kg net weight: more mass, more payload, a three-phase AC380V supply, and a slower published take-out time than the open-type unit.

The Six Cost Drivers That Set the Quotation

Six specification drivers explain almost all of the movement between two quotations on the same tonnage, and if you fix all six in writing before you ask for pricing, the quotations you receive become comparable for the first time. I take buyers through them in this order on a first call, because each one narrows the next one.

Driver 1 — Stroke and reach envelope

The reach envelope is the largest single cost driver in this band, because the vertical stroke has to exceed the mold-open stroke plus the part height plus the gripper clearance, and the transverse reach has to cover the mold face, the placement station and the downstream conveyor. Across our published line the vertical stroke runs from 700 mm on the 700 class to 1300 mm on the 1300W class, and the transverse reach from 1360 mm to 2000 mm over the same span. Because a longer reach envelope means more structural mass, a larger actuator and a higher servo rating, the reach figure moves the price further than any option on a quotation addendum.

Driver 2 — Payload class

Payload class is the second driver, and it is the one most often left unstated. Our published SPRE 3-axis and 5-axis series is rated LOAD 6KG across the 90–470 ton band; the open-type SPRT3S1000W class is rated 3 kg; the high-speed SPRT3S1200I class is rated 10 kg. Because the payload rating determines the gripper, the wrist bearing and the drive train, a quotation specifying a payload class well above your actual part weight plus gripper weight is charging you for capacity you will never use — so insist on the rating being written into the quotation, with your real part weight next to it.

Driver 3 — Repeatability and positioning class

Repeatability is the third driver, and I want to be straightforward: our published tables for the SPRE series carry stroke, gripper angle, maximum load including gripper, minimum take-out time, drive system, working air pressure, air consumption, the biggest power and the largest net weight — but they do not carry a repeatability figure. I have checked our own tables repeatedly on this point, because it is the specification engineers ask me about most often. So require every supplier, including us, to state position and path repeatability in writing against the ISO 9283 performance criteria and validation method, then validate it on your own floor with your own tooling. A verbal repeatability claim is not a specification.

Driver 4 — Servo platform and controller architecture

The fourth driver is the servo platform and the controller, and it is where the plant installation starts to appear in the cost. The published drive system across this line is an AC servo motor on X, Y and Z, with the controller running on AC220V ±10%, 12A, 50/60Hz single phase for the lower classes and AC380V ±10%, 12A, 50/60Hz three phase on the high-speed and three-phase variants. Because a three-phase supply changes the electrical installation scope at your plant, and a higher-tier controller changes the motion profile and recipe-changeover capability, the controller architecture is a cost driver even when the arm looks identical in the photographs.

Driver 5 — Integration interface and end-of-arm tooling

The fifth driver is the integration interface, and it is the one that most often separates two quotations that otherwise look identical. Our published tables document the drive system, the working air pressure of 5–7 kgf/cm² and the air consumption in NL per cycle, but they do not name the injection molding machine handshake protocol in the specification line — so require the protocol to be stated in writing, alongside the end-of-arm tooling scope. Because the handshake protocol and the tooling determine whether the robot can run your full part portfolio or only one part, the cheapest robot in the comparison is frequently the one that needs custom tooling for every job you run.

Driver 6 — Engineering, commissioning and service commitment

The sixth driver is the engineering commitment behind the shipment, and it is the only driver a buyer can verify almost entirely from the supplier’s behaviour before any money changes hands. Ask what commissioning on your floor is included, how many days of operator training are included, what the recommended spares list is, and what the warranty and service response are. Because a quotation carrying a clear service commitment reduces the risk of a six-figure line stopping, while a quotation without one transfers that risk entirely to your plant, the commitment is a cost even though it never appears as a number.

What Is Not in the Take-Out Robot Quotation

The most common sourcing error I see in this band is comparing the robot line from one supplier against the robot line from another, when each supplier has quietly scoped a different amount of work into that line. Here is what is normally outside it, and what I ask every buyer to put on a separate schedule before comparing quotations.

• Installation and mechanical set-up. The robot arrives as a machine, not as an installed cell, so foundation work, levelling, guarding and the physical set-down are quoted separately.
• End-of-arm tooling. The gripper, vacuum generation, suction cups or needles and the quick-change tooling interface are a separate line, and they change every time you change part.
• Vision and in-mold labeling add-ons. Camera, lighting, label feeding and the matching cell logic are quoted as options, and they belong to the robot for IML scope rather than to the standard arm. Because the label is placed while the part is still hot, an IML cell should be quoted as a cell, not as a robot with an option.
• Safety guarding and the cell perimeter. The guarding solution must satisfy the industrial robot safety requirements of ISO 10218-1 and the robot system requirements of ISO 10218-2; in North America the equivalent ANSI/A3 R15.06 framework applies, alongside the electrical requirements of IEC 60204-1.
• Spares, training and commissioning. The recommended spares list, the training days and the on-floor commissioning effort are real costs that sit outside the arm.
• Running cost: compressed air and power. Our published air consumption of 1.0 to 1.8 NL per cycle across the SPRE line, and 2.0 NL per cycle on the open-type SPRT3S1000W, is a cost per year and not per machine, and it is the figure most often ignored when a buyer builds a payback case.

How to Compare Take-Out Robot Quotations Line by Line

This is the sequence I use on every first call, and it is the reason buyers tell me their comparison finally made sense once they had it in front of them. Work through it in order, because each step removes an ambiguity that makes the next step meaningless.

1. Fix the model family from the clamping tonnage, the part weight and the mold-open stroke. Match those three numbers against our published coverage windows of 90–200 ton, 160–320 ton, 250–470 ton and 380–700 ton, and put your tonnage in writing on every request.
2. Lock the reach envelope against the real mold geometry. Require the vertical stroke and the transverse reach as numbers, and check that the vertical stroke exceeds the mold-open stroke plus the part height plus the gripper clearance.
3. Check the payload class against your real part weight. Compare our published rating of 6 kg for the SPRE series, 3 kg for the open-type SPRT3S1000W and 10 kg for the high-speed SPRT3S1200I against your part weight plus gripper weight, and reject any quotation that leaves the rating unstated.
4. Require repeatability in writing against ISO 9283. Ask for position and path repeatability on the published test method, and treat a verbal claim as no claim at all.
5. Lock the interface, the electrical supply and the air envelope. Require the machine handshake protocol to be named, the controller supply to be specified, and the air consumption in NL per cycle to be stated, because these three figures drive the installation scope and the running cost.
6. Get the installed scope, the spares list and the service commitment in the same document. Separate the robot, the controller, the tooling, the installation, the guarding, the training, the spares and the commissioning onto individual lines, and add the warranty period and the service response.

How to Estimate the Payback Without a Published Price

You do not need a published price to build a defensible payback case — you need four measured inputs and a running-cost model, and I would rather show you the method than hand you a number I cannot stand behind. Here is the structure I use with buyers who have to present a case to their own management.

Step one: establish the cycle-time input from our published data and then from your own floor. The published minimum take-out time for the class you are quoting gives you a floor — 1.8 s on the 900I, 1.6 s on the 1100W, 1.7 s on the 1300W — and your own measured cycle on the real machine gives you the number that matters, because the robot must fit inside the cycle rather than beside it.

Step two: count the operator positions the cell removes. This is the largest single benefit and the easiest to overstate, so count positions rather than operators, and count the positions that genuinely disappear rather than the ones that merely change.

Step three: build the running-cost side from the published figures. Air consumption in NL per cycle multiplied by cycles per year multiplied by your compressed air unit cost gives the air bill; add controller power, the spares list and the maintenance hours. Because a robot consuming 1.8 NL per cycle on a fast cycle can cost more in compressed air over five years than a cheaper robot costs in energy, the running-cost model is what separates a good investment from an expensive one.

Step four: divide the installed cost by the net annual benefit. Net annual benefit is the labour and scrap avoided minus the running cost, and the result is a payback period in months. Present the installed cost, not the robot line, because the installed cost is what leaves your bank account. And run the same model against two configurations, because the comparison that justifies the higher-class robot is almost always the one with the faster take-out time and the shorter payback — not the one with the lower quotation.

Frequently Asked Questions About Take Out Robot Cost for a 200–650 Ton Injection Molding Machine

How to Get a Model Recommendation and a Written Quotation

Send me four numbers and I will send you back a model recommendation and a written quotation within one business day. The four numbers are the clamping tonnage of your injection molding machine, the part weight including the runner, your current cycle time, and the handshake protocol your machine controller speaks. Add the mold-open stroke and the placement distance if you have them, because those two figures settle the reach envelope immediately and remove the largest source of variation between quotations.

If you would rather browse first, our take-out robot series gallery shows the configurations, the 3-axis and 5-axis servo robot arms page carries the standard specification tables, the telescopic type page covers the deep-cavity configurations, and the high-speed robot page covers the fastest take-out units in the line. Our downloadable catalogue is on the download page, and the contact page is where the specification goes.
