Gelcoat Reciprocator

Designed to automatically produce flat panels or sheets using chop/wet-out gun

The Gelcoat Reciprocator Unit is designed to automatically produce flat panels or sheets using a chopper gun and/or gelcoat spray gun that traverses a mold or table. Spray-up and rollout are both completely automated, and some contoured shapes may be produced when part of the rolling is performed by hand. The system travels at about 5 feet/second (1.5m/second) across the table and is capable of applying a 15 mil (.38mm) gel coat with a tolerance of +/- .005 inch (.127mm). A maximum production rate of 5400 square feet/hour (500 square meters/hour) has been attained at 15 mil thickness. When the digital read-out system is used, accuracy can be monitored during set-up and operation of the machine. Includes pumping systems, nitrogen charging system, hooded fume collectors with filters and 3/4 HP exhaust fan.
