The MRC-600-E post repair system is designed for round ends with diameters from 52.5 mm (202) to 99 mm (401). (Other sizes on demand). The lacquer is applied in a spray station and it is dried in a convective tower oven. The conveyor speed is adjustable from 100 up to 600 ends per minute.

By means of the downstacker that has a turned end and low level detector installed, the ends are driven to the spray station. There, a rotating head fitted with a Peñalver pneumatic airless spray gun applies the lacquer in only one pass. The rotary head gun speed is adjustable and assures the accurate spray on the score line. The new rotary head lets you, choosing the suitable nozzle, cover also the rivet or all the end's surface. This is possible using solid tungsten carbaid seals designed specially for this application.

A dog chain conveys the end with a forward and stop movement, right into the spray station stop, where the gun sprays the score and optionally the rivet (by a wider spray pattern). The spray gun has a seat for interchangeable nozzles, which are available for different flows and patterns.


The vertical oven completely integrated in the compact unit design provides the necessary temperature and time to achieve the lacquer curing. The oven incorporates a cooling chamber to decrease the temperature at the oven exit. The temperature range goes from 60°C up to 200°C using the new hot air generator developed with Peñalver. The heating and cooling are produced by convection inside the oven, for this purpose the oven has ventilation turbines and a fume outlet. The oven is supplied with electric heaters or a gas burner (100mbar or 1bar) depending on the customer's preferences. By construction and design jams and end damages are nearly impossible. Fans in the oven are equiped with security systems to assure that the flows are correct and an accumulation of gases fail will never occure. A VOC level monitor always advises if the % in the oven begins to be dangerous.


The unit includes an electrical cabinet and lacquer equipment (own or shared). The PLC and control system are located in the electrical cabinet, on which the temperature and revolution gauges are visible. In the lacquer cabinet is installed a security system to behave so that leakages do not appear on the hoses. All the electric components installed are explosion proof and ATEX certified.

On the unit, a button and synoptic panel show the alarms and other relevant information. The lacquer system includes a pump and other devices such as filters and regulators for the required application within the established parameters. The desired amount of lacquer per end can be achieved (within a range) by modifying the pump pressure and installed nozzle (different flow).
