HVS40iXXL with turntable

Standard heat sealing system of a larger design and construction to allow integration of additional functions and the use of a turntable up to 500mm diameter for larger components, which cannot be fitted on a smaller turntable.. While the external workpiece holders are being unloaded and re-loaded with new workpieces, , the product within the machine is heat sealed.

In this example, two plastic pins are formed with two separately suspended heat sealing dies. This arrangement is necessary when the maximum size needs to be monitored. In contrast, with a situation involving a multiple heat sealing head, the heat sealing dies can be individually suspended so that the temperature at each sealing position can be controlled and monitored, the component detection and sink depth per pin established and the process force dedicated to each individual heat sealing die can be applied.

Temporarily heated system, where active cooling of the product takes place after the heating phase.

A Stand-alone system which can be operated from a standing or sitting operating position.

The HVS 40i is quoted by us as a “modular” system. Consequently, we can meet customer functional specifications from simple systems, which are purely thermally monitored, to completely process-monitored expansion sections with component raised- and lowered-distance measurement, permanent force measurement and data communication (Traceability).

The XXL series allows the application of up to 3 independently working heating circuits or multiple turntables, split into three or four sections.

The relevant heat sealing tools are matched to the product and the control circuit of the system is designed for the connection of single dies to the use of complex, multiple heat sealing heads (e.g. for use in sealing of 10 or more simultaneous processes. The shaping dies are manufactured in-house to meet customer specifications. The heat sealing heads can be very rapidly changed over.

Our innovative coating technologies ensure the maximum possible operating life of the heat sealing die even with extremely compact plastics and provide maximum resistance to the abrasive wear and erosion to which the forming surfaces in contact with the product are exposed. Coatings with a micro hardness (HV 0.05) up to 3,300 are used.

System control allows freely programmable heating and cooling phases, comprehensive monitoring functions (warning- and malfunction messages for all possible parameters), workpiece or maintenance counters, storage of manufacturing parameters for 10 or more products, possibility of displaying all identified process parameters etc. All changes to process-relevant parameters are password protected. Serious fault reports, (such as the breaching of malfunction values or repeated alarms) can only be overridden by means of an additional key switch.

In combination with the safety casing, the system satisfies all working safety requirements. The safety door of the housing, which is monitored by a safety switch, can be can be unlocked and opened by a key switch. Consequently, the system functioning can be controlled during set-up and maintenance operations or heat seal head replacement can be carried out.
