Roemheld introduces new rail-guided RWS mold changing table for transporting heavy dies and molds

Fenton, MO — ROEMHELD North America announces the new, rail-guided RWS mold changing table for transporting heavy dies and molds. The innovative solution is available in three versions for loads of up to 15, 25, or 40 tons per mold. Electrically driven, the system is equipped with two different pull-push systems for the safe and automatic transport of dies to set up presses. It can be used to change dies and molds on all types of machines, including vertical forming and injection molding machines.

RWS is ROEMHELD’s answer to today’s trend where loads in die and mold making are ever-increasing. This solution helps car manufacturers integrate numerous individual parts into increasingly large castings, for example in megacasting for frame or body manufacturing. They are processed with heavier molds in larger presses and punches. ROEMHELD understands these new requirements and is expanding their range of mold weights to accommodate heavier loads.

The mold changing table is guided on floor-level round rails. These rails have a rolling resistance so low that loads of up to 5 tons can easily be moved manually by just one person. In addition, the rails are designed to facilitate precise carriage guidance and to prevent dirt deposits and tripping hazards in the floor.
Consoles that bridge the distance between the press bed and the mold changing cart make transport effortless. RWS has an integrated pull-push system that moves the mold onto and off the press bed via roller rails. A safety mechanism ensures that the loads can only be moved when the RWS mold changing table is firmly attached to the press or the storage space.

RWS is available as a single or tandem cart and can be used flexibly in a wide range of production scenarios. For example, it can travel between a storage space, a set-up station, and a single press. It can also shuttle between several bearing locations, set-up stations, and presses. Alternatively, it also enables several presses to be connected to just one changing table. This means that the presses are free during preparation and can produce right up to mold change.

With this solution, ROEMHELD is able to meet the growing requirements of customers resulting from today’s trend of employing connected presses and complete solutions. Molds of different sizes can be easily changed with one system because a standardized base plate is used. Semi-automatic and fully automatic mold changes are possible thanks to the control system that is integrated in the cart and precise positioning. Other available features include integration with the press control, and the ability to combine with a rapid-clamping system for molds.

The amount of time needed for the actual changeover is also minimized because the mold changing table is equipped with integrated lifting bars and a pull-push system. Also important for operators: in the semi-automatic system version, the cabled remote control (wireless also available) enables simple, safe, and centralized control of the cart.
Compared to free-moving transport systems, the rail-guided mold changing table receives high marks with numerous advantages: maximum repeatability and precision of up to ±0.3 mm, lower energy consumption and space requirements, and greater availability. In addition, the installation of floor-level round rails generally places fewer demands on the factory floor.

RWS rounds out ROEMHELD’s comprehensive, integrated portfolio of solutions for transporting and changing dies and molds from the rack system to the press bed. This set-up time optimizes the solution and thus meets customer requirements for complete systems that store, transport, change, and clamp-forming dies.
