The pre-forming line AR-D is a flexible forging line for volume distribution of long forging parts. The design of the line allows the production of a variety of different work-pieces without time-consuming tool-changes. It consists of the forming machine and two manipulators driven by servo motors.
The forming unit is a press with horizontal operation and two rams moving towards each other which perform a sinusoidal motion and are driven hydraulically.
As a special feature the ram movement is not realised via valve control. Thus the hydraulic system works without any pulsation and with extremely high efficiency. A combination of electric servo motors and hydraulic pumps (servo pumps) allows the dynamic adjustment of the ram stroke position so that parts with a large variety of contours can be produced.
Due to its technical concept the line can be seen as an alternative to radial forging lines, open-die forging lines and traditional stretching lines.
Special features:
- Low tool costs
- Universal use of forming tools
- High energy efficiency
- Fast stroke sequence - 200/min
- Fewer intermediate heating cycles necessary due to quick operation
- Fewer operations and less time for tool-change
- Suitable for large forging parts even for small batches
The extremely rigid cold extrusion press KFP with flexible force-displacement characteristics is ideally suited for the near-net-shape production of work pieces.
With the multiplex press, LASCO achieves unprecedented flexibility. The combination of servo-hydraulic press with integrated impact forming presents new possibilities in forging technology.
Capacities:
Press force 2,500 ? 20,000 kN
Forming impact 20 ? 80 kJ
A special feature of the incremental LASCO forming press is the combination of the hydraulic servo direct drive for the feed movement of the lower piston with a dynamic torque motor for the actual incremental movement. This allows the incremental cycle to be started and stopped in the correct position - and implemented with absolute precision.
With the VPE/VPA series and numerous options, extensive accessories and automation possibilities, LASCO offers the optimum press concept for preforming, trimming, piercing, forward and backward extrusion, upsetting and stretching.
The VPZ hydraulic piercing and drawing press is specially designed for forward and reverse extrusion with subsequent drawing of long rotationally symmetrical bodies.
Power dimensions:
Pressing force 5,000 - 40,000 kN

Horizontal forging machines are proven forming units which are used for both preforming and finish-forging. The hydraulic horizontal forging machine eliminates the disadvantages of the rigid coupling between clamping and upsetting drive of the conventional mechanical design.
The hydraulic multi-axial press MAP pursues the goal of achieving optimum material utilization through several forming axes. It can be used both as a pure forming unit and as a combined preforming/finish-forging unit.
Hydraulic deep-drawing presses are particularly suited for difficult drawn parts and special materials. Specialized in hydraulically driven forming units, LASCO designs deep-drawing presses that are customized to meet even highest demands of sheet metal forming.
A special feature of cross rolling is the axial feed cross rolling. The axial feed cross roll is used to preform small quantities of billets to special geometries. The round material is actively drawn through two forming rollers. The diameter reduction is achieved by radial adjustment of the forming rollers.
The cross wedge roll is designed for the preforming of round material and is ideally suited for the finish-forming of e. g. gear shafts, stepped as well as hollow shafts. The QKW can be used both as a stand-alone unit and as an integral part of an automated forging line.
LASCO manufactures electric upsetting machines in horizontal and vertical arrangement in special constructions, however not in fixed type series, but adapted to special market and customer requirements.
The application of the electric upsetting process circumvents certain technological limits of mechanical upsetting machines ? economic efficiency increases. All commercially available steels and non-ferrous metals including high-temperature nickel alloys can be upset in the electric upsetting process.
The forging roll is designed for preforming round and square material. The billet is fed radially into the rollers by a manipulator and preformed in individual sectors (mostly 2 to 5 passes).
The skew rolling mill is used to produce preforms for weldless tubes. Starting from round material, a reverse extrusion operation is first carried out with a hydraulic press. The preformed billet is then threaded horizontally onto the mandrel of the skew rolling mill. In the subsequent forming process, the wall thickness of the tube billet is gradually reduced using several active rollers.
The hydraulic double-acting hammer HO-U is an ideal forming unit for the forging industry from a technical and economical point of view. Maximum forming force is generated with minimum effort. Due to its forming characteristics, the hydraulic double-acting hammer is a universal forging unit for a wide range of applications.
LASCO is pioneer and inventor of the drive system for hydraulic hammers. The automation system developed by LASCO for automatic forging with die forging hammers opens up new fields of application.
The counterblow hammer GH is preferably used for particularly heavy parts demanding blow energies of more than 200 kJ.
LASCO is pioneer and inventor of the hydraulic drive system for hydraulic hammers. The LASCO die forging hammer type GH has a fully hydraulic drive and thus a significantly higher energy efficiency than conventional air-operated hammers.
