If you want to sell a used KraussMaffei injection molding machine, we give you a first assessment. We buy the hydraulic CX series, the hydraulic GX series with a two-platen clamping unit and the large MX series for big automotive parts. There is no commission on a direct purchase, and payment is made by bank transfer before pickup. KraussMaffei Group (historically Krauss-Maffei, often written Krauss Maffei) is based in Munich and is one of the best-known names in injection molding. For the whole market, see Sell injection molding machines.
A note first: on this page we deliberately name no flat prices. For the CX 200, GX 450 and MX 850 we have no reliable public price range, nor for other sizes such as the smaller AX series. We value every machine individually by clamping force, year, control generation, shot count and condition.
CX: the compact hydraulic series
The CX series covers the compact clamping force class at KraussMaffei and is hydraulically driven. It is the typical entry machine for processors with standard applications and is correspondingly widely represented on the used market. The hydraulic drive makes the CX robust and easy to maintain, which shows in stable demand even after many years of operation.
GX: the hydraulic two-platen series
GX is KraussMaffei’s hydraulic series with a compact, hydromechanical two-platen clamping unit and, according to the manufacturer, covers clamping forces from 4,000 to 14,500 kN. The GX 450 at 4,500 kN (450 t) sits at the lower end of this series. Used KraussMaffei machines are traded within Germany and exported to Eastern Europe and Asia.
MX: the large series for big automotive parts
The current MX series is hydraulic with a two-platen clamping unit and, according to the manufacturer, reaches up to 60,000 kN; the MX 850 (8,500 kN) is an older, smaller size. The series is designed for large components such as those found in automotive manufacturing: bumpers, large trim parts, structural components. On these machines, besides condition and shot count, the size of the injection unit and any multi-component units decide the price you can achieve.
MC6 and MC5: the control generations
Current KraussMaffei machines run on the MC6 control, older machines carry the predecessor generation MC5. A machine with MC6 sells more easily, because the current operating logic is established in processing plants. MC5 machines are therefore not unsellable, but they sit in a lower price segment than a comparable machine with the current control.
The models at a glance
| Model | Clamping force | Drive | Price information |
|---|---|---|---|
| CX 200 | 200 t (2,000 kN) | hydraulic | no reliable public range |
| GX 450 | 450 t (4,500 kN) | hydraulic, two-platen | no reliable public range |
| MX 850 | 850 t (8,500 kN) | hydraulic, two-platen | no reliable public range |
For the smaller AX series and for other sizes within CX, GX and MX we also have no reliable public price ranges. We value these machines individually by clamping force, control generation, shot count and condition. How we value in general is explained under What is my injection molding machine worth?. An asking price is not a sale price, and we do not present one as a guide value.
Factors that determine the price
Clamping force class: decides which of the three series, CX, GX or MX, your machine belongs to, and so the basic price frame.
Control generation: MC6 versus the older MC5. Both find buyers, but at different price levels.
Shot count: the central wear indicator, visible in the condition of screw, barrel and non-return valve.
Injection unit size and multi-component units: a clear value driver, especially on the MX series, because they widen the range of possible applications.
Hydraulic oil condition: relevant for CX and GX. Contaminated oil speeds up wear on the hydraulic components.
Export suitability: KraussMaffei machines enjoy high standing internationally, which shows in a group of buyers beyond Germany.
KraussMaffei compared with other makers
Compared with Arburg, whose modular Allrounder concept is strong above all in precision molding (see Sell Arburg), and with Sumitomo Demag, which focuses on packaging and precision applications (see Sell Sumitomo Demag), KraussMaffei covers a particularly wide clamping force range with CX, GX and MX, up to the very large tonnage range. That is relevant in the automotive environment, where large parts require high clamping forces.
Sell a KraussMaffei CX 200
The CX series is the manufacturer’s fully hydraulic line (500 to 4,200 kN according to the manufacturer) and, with the CX 200 (2,000 kN, 200 t), covers the smaller to medium clamping force segment. It is a proven, widely known concept with a correspondingly broad group of buyers on the used market. Spare parts and service knowledge are available practically everywhere, which makes resale easier.
Besides shot count and the condition of screw, barrel and non-return valve (see the factors above), these points decide the price of your CX 200:
- Hydraulic oil condition: especially relevant on a purely hydraulic machine. Dark, contaminated oil is a warning sign of accelerated wear.
- Control generation: a more current control version appeals to a wider group of buyers than an older proprietary control.
- Additional equipment: a removal robot, temperature-control units or material conveying sold with the machine raise the total price compared with the basic machine.
Buyers of a used CX 200 come mostly from small and mid-sized processors for whom 200 t is the right class for standard parts. A CX 200 is typically sold on capacity adjustment, a switch to an electric machine for tighter tolerances, or a plant closure in which the whole machine park becomes free at once.
Sell a KraussMaffei GX 450
KraussMaffei has a broad installed base and an active export trade to Eastern Europe and Asia, and spare parts and service knowledge for the series are available worldwide, a factor often missing with less common makes.
Besides shot count and the condition of screw, barrel and non-return valve (see the factors above), these points decide the price of your GX 450:
- Control generation: MC6 is current, MC5 the older generation. MC6 tends to be valued higher because it appeals to a wider group of buyers.
- Injection unit size and additional equipment: a second injection unit or a multi-component unit widens the group of buyers beyond standard parts and lifts the price over the basic version.
- Hydraulic oil condition: dark, contaminated oil on a hydraulic clamping unit is a warning sign of accelerated wear.
A GX 450 with a high shot count is still sellable. What counts is the real condition of barrel, screw and non-return valve, not the shot count alone. A GX 450 with documented maintenance and an intact screw assembly stays in demand, even after a high number of shots. Buyers come mostly from automotive supply and technical parts manufacturing, for whom 450 t is the right class for mid-sized components.
Sell a KraussMaffei MX 850
For large automotive parts, mold area and clamping force are the decisive parameters. The used market for machines of this size is more fragmented than for compact machines, but very active internationally, especially in export to Asia and Eastern Europe, where new automotive supplier plants are being built.
Besides shot count and the condition of screw, barrel and non-return valve (see the factors above), these points decide the price of your MX 850:
- Platen area and tie-bar spacing: they decide which range of parts the machine can still run; a larger tie-bar spacing widens the group of buyers.
- Hydraulic oil condition: on a machine of this size with a correspondingly large hydraulic system, a particularly telling condition indicator.
- Additional equipment: an integrated removal robot for large parts or a multi-component unit raises the price over the basic version.
Buyers of a used MX 850 come very largely from automotive supply and large technical parts manufacturing, for whom 850 t is the right class for large trim and structural parts. Typical reasons for selling are a model change at the end customer, a move of production abroad or a complete plant closure.
Transporting a machine of this size is considerably more involved than for smaller ones. It requires heavy-load transport, and an on-site viewing before we confirm the offer is usual. We organise the whole logistics, including permits for heavy-load transport where required.
How selling works
Step 1, send the details: exact type designation, series, clamping force, year, shot count and details of the injection unit and additional equipment. If possible, photos of the control panel and clamping unit. Free of charge and without obligation.
Step 2, first assessment: we assess your KraussMaffei machine on current market data. The offer usually follows 24–48 hours on working days after we have all the details. If it is urgent, an on-site visit is possible, usually within 48–72 hours on working days.
Step 3, payment and pickup: on a direct purchase, payment is made by bank transfer before pickup, and we organise dismantling, including draining hydraulic oil and temperature-control fluids, and transport. The whole process usually takes 7–15 working days. The complete process is under How it works.
Typical reasons for selling
- Workshop modernisation. An older CX or GX makes way for a new machine. See Workshop upgrade and trade-in.
- Plant closure or insolvency. Whole machine parks with several KraussMaffei series: we assess the entire inventory in one visit. See Plant closure and machinery liquidation and Insolvency and machinery liquidation.
- Capacity reduction. Individual MX machines become free when utilisation falls in the automotive environment. See Idle machine capacity.
- Plant relocation. Companies often decide to sell large MX machines before a move rather than transport them. See Plant relocation.
