Injection Molding & Extrusion
Used Krauss Maffei GX 650: Sell or Buy at Auction
KraussMaffei is a German manufacturer of injection molding machines, reaction process machinery, and plastics extrusion systems, serving automotive, aerospace, medical, and industrial plastics markets. KraussMaffei's CX, MX, and GX series injection molding machines range from small technical parts to very large structural components. The brand is particularly strong in automotive exterior and interior components.
The KraussMaffei GX 650 is a two-platen injection molding machine from KraussMaffei's GX series, a large-tonnage member of the line rated in the 650 metric ton clamping class (about 6,500 kN) and run from the manufacturer's MC6 multiTouch control. KraussMaffei built the GX series to bridge the gap between its more compact CX machines and its larger MX machines, so the GX 650 sits in the range shops choose for sizable technical parts and generous mold sizes rather than small, fast-cycle work. Because it uses a two-platen clamping unit, the machine is noticeably shorter than a comparable toggle press of the same tonnage, which frees floor space while still offering a large platen area and wide tie-bar clearance for bulky tooling. A GX 650 ships in several injection-unit and screw-diameter configurations, and that shot capacity, together with installed options like Adaptive Process Control, core-pull circuits, and integrated robotics, is much of what separates one used unit from another. Buyers who search for a used GX 650 are usually large-part molders: automotive suppliers running door modules, interior and exterior trim, and front-end or under-hood components, along with industrial molders producing totes, crates, containers, and heavy technical housings that need real shot size without the lead time of a new build. KD Auctions markets machines like the GX 650 to its network of 500,000+ industry contacts, where the limited domestic supply of two-platen presses at this tonnage tends to draw both regional buyers and international rigging crews into competitive bidding.

What is a used KraussMaffei GX 650 worth at auction?
There is no set price. Value on a GX 650 tracks its age, running hours, and overall condition, the injection unit and screw size it carries, the control and process options installed, and any tooling, robotics, or auxiliaries included in the sale. KD Auctions provides a free AMEA-accredited, USPAP-compliant appraisal that documents both orderly liquidation value (OLV) and forced liquidation value (FLV), so you have a defensible figure before the machine goes to market. If you decide to sell, the commission is tailored to the engagement and quoted upfront, and most sellers pay nothing out of pocket.
How does the GX 650 compare to KraussMaffei's CX and MX series?
All three are KraussMaffei lines built for different part sizes. The GX is a two-platen design that KraussMaffei positioned to bridge the gap between its smaller, more compact CX machines and its larger MX machines, and at roughly 650 metric tons of clamping force the GX 650 sits well up that range. A plant reaches for a GX 650 when it needs a large mold-mounting area and real shot capacity for big parts, which is why buyers shopping this specific model are almost always large-part molders rather than general-purpose shops running smaller CX-class tooling.
