Questions that come up before every investment decision, answered without marketing language. These pages carry no publication date because the physics does not change.
How is capacity determined when selecting an extrusion press?
Press capacity is not chosen from profile width; it starts from container diameter and extrusion ratio. Five questions to answer before investing.
Details Project managementTechnical specification mistakes when buying machinery from China
Most problems in buying extrusion equipment from China come not from the machine but from an incomplete specification. The eight most common gaps.
Details Project managementModernization or a new press investment?
