Injection Molding & Extrusion
Used Krauss Maffei GX 450: 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 450 is a two-platen injection molding machine whose model number reflects its rated clamping force of 450 metric tons, roughly 4,400 kN. That tonnage suits mid-to-large plastic parts that outgrow a standard toggle-clamp press: automotive interior and structural trim, appliance components, and heavy-wall industrial housings. The two-platen clamp does away with the toggle linkage used on KraussMaffei's smaller presses, so the GX 450 fits a larger mold and wider tie-bar spacing into a shorter overall machine length than a comparable toggle press of the same tonnage, which is why processors tight on floor space favor the design. It typically runs KraussMaffei's MC6 control and is often configured with a servo-hydraulic drive to hold down energy draw. Buyers for this specific model tend to be automotive Tier 1 and Tier 2 molders and industrial plastics processors that need genuine tonnage and shot size but not the largest MX or upper-range GX machines, which makes the GX 450 a workhorse rather than a niche mega-press. Whether a shop is buying a used GX 450 or selling one, KD Auctions reaches that focused pool through its 500,000+ industry contacts, and the German engineering behind the GX line tends to draw both domestic and export bidding once rigging, drive configuration, and mold-mounting details are documented.

What is a used KraussMaffei GX 450 worth at auction?
Auction value for a GX 450 depends on its age, hours, overall condition, control generation, drive configuration, and any included tooling or mold-mounting accessories, so a single blanket figure for the model is not meaningful. Before deciding how to sell, an owner can request a free AMEA-accredited, USPAP-compliant appraisal that reports both orderly liquidation value (OLV) and forced liquidation value (FLV), then weigh those against a managed auction. KD Auctions runs managed sales on a 6 to 10 week timeline from engagement to payout, with onsite dispatch within 48 to 72 hours, and commission is tailored to the engagement and quoted upfront, so most sellers pay nothing out of pocket.
How does the GX 450 compare to KraussMaffei's larger GX and MX presses?
The GX 450 sits at the lighter end of KraussMaffei's two-platen lineup. It brings the larger mold-mounting area, wide tie-bar clearance, and compact footprint of the two-platen design without stepping up to the multi-thousand-ton MX and upper-range GX machines built for full bumper fascias or pallet-size structural parts. That makes it a practical fit for automotive interior and structural trim, appliance housings, and mid-size industrial components, where 450 metric tons of clamp is enough to fill the part without paying to run and rig a press sized for far heavier work.
