This new digital controller is far more efficient at maintaining tool temperature and responding to demands. This technology reduces the effort required for operation, making the tool easier to use and reducing fatigue while also decreasing tool wear. This translates to increased speed and decreased work time with less maintenance and longer service life.

The gun can detect when the trigger is pulled frequently and will boost the power to the heater in response to this increased demand. By doing this, the gun ensures that the adhesive is applied at the optimal temperature.

The microcontroller also detects periods of non-use and gradually reduces the temperature. After two hours of not being used, the gun automatically turns off. A pull of the trigger resets the tool and reverts to the set temperature. This feature not only saves energy, it also improves reliability and is an important safety feature.

The controller also features a protection circuit which will detect various fault conditions and indicate these with a rapidly flashing indicator. If a fault occurs, the tool will automatically shut down, preventing damage to the tool and potential injury to the user.

Overtec 820-15

The Overtec 820-15 is a heavy-duty, medium-sized 15mm (⅝″) glue gun. Features include an adjustable temperature, fast recovery, medium output, two-minute warm-up time, and lighted on/off switch. This gun is designed specifically for use in the Overtec molding system.

The Overtec system is a low-pressure molding process that uses a special thermoplastic resin to produce high-quality sealing and protection of components. This system is faster and cheaper than injection molding.

OVERTEC 820-15 feature

This innovative process falls somewhere between casting and injection molding. The Overtec system uses a low injection pressure that allows fragile and delicate components to be encased and protected without risk of damage.

The Overtec molding system eliminates the need for traditional housings and casings used in potting. It also does not require the heat curing process, which saves on energy costs. There is no need for two-part resins, meaning no mixing and no wasting of materials. Reduced consumption of energy and materials means lower cost to the user.

The system uses an environmentally friendly high-performance molding resin, Overtec 5 FR, that is made primarily of renewable materials and is solvent free. Overtec 5 FR does not require mixing, saving time and reducing waste. The resin has no shelf-life limitations. This material offers water-tight encapsulation, chemical resistance, and excellent temperature resistance.

Molds can be made from aluminum, which is easy to mill. It also has good thermal conductivity, making it the ideal material to make the mold sets out of. Molds made of aluminum usually have a long lifespan, aided further by the lack of abrasive or corrosive ingredients within Overtec 5 FR. These molds cool the component quickly and allow easy release of the molded pieces when the process is complete.

OVERTEC 820-15

The most popular applications for the Overtec molding system include PCB overmolding, electronic component encapsulation, automotive electronics, connector potting, grommet injection, molded connectors, and many others. In many cases, the molding can provide strain relief and protect the component against environmental conditions.

How does it work? The process is simple. Load an Overtec 5 FR resin stick into the Overtec 820-15, power it on, and wait for it to heat up to operating temperature. Once the gun is heated, place the nozzle of the gun inside the hole in the mold. Fill the mold applying consistent pressure. When the mold is full, you will feel resistance in the trigger pull. Keep pressure on the trigger for a few seconds to prevent shrinkage. The resin will cool and set within a few seconds. At this point, the mold can be opened and the overmolded components can be removed. Release sprays can be used to aid in part-removal if desired.
