WOLLIN, a specialty developer of release agent-spraying systems for diecasting molds introduced a new series of machines called Efficient Spray Machine (or ESM), replacing its PSM2-4 mold spraying machine series. ESM is an abbreviation and stands for Efficient Spray Machine.
The new design was introduced this month at Euroguss 2020.
While retaining its proven guide rail technologies, most of the mechanical parts have been replaced. Options like flow measurement, pressure control, and pressure booster have been integrated into the horizontal axis to reduce the space required on the diecasting machine and the weight on the vertical axis.
The new design is reinforced and the stability of the axes have been improved by improving the useful length of the previous guides, resulting in a 25% increase in payload.
The ESM is comparable to the previous PSM mold spraying machine in terms of space requirement and console position, though service accessibility has been significantly improved, according to the developer.
Thanks to the complete Industry 4.0 implementation, it is possible to integrate all functions and settings into the user interface of the diecasting machines with the newly developed PC3 control. The PC3 also takes future safety requirements into account.
The supply line for the release agent concentrate has already been integrated into the machine, which considerably simplifies the ex- tension of the Eco-Spray option and the use of dosing nozzles. The selection of release agents for conventional spraying or concentrate spraying is now possible without disassembling the spray tool.
Microspraying with the Wollin EcoSpray system eliminates waste water, and reduces release agent consumption and energy requirements for compressed air and die-temperature control. As a result, the diecasting process becomes more environment-friendly. Also reduced is the thermal shock and heat cracking caused by cooling with water, which results in significantly increased die-service life.
Casting porosity and surface quality results also are improved. Some additional costs for more complex mold-temperature control and spray technology will be quickly amortized by the savings achieved, often within a few months, according to the developer.
