FREQTIS^® includes two grades, one grade based on LCP and one based on PPS.

Here, the following introduces the molding conditions of FREQTIS^® and provides a separate description for each base resin depending on item.

Recommended conditions:

Temperature: 140 to 160℃

Time: 4 to 6 hours

Rear part: 320 - 325℃

Middle part: 325 - 335℃

Front part: 335 - 345℃

Nozzle: 320 - 350℃

Do not set the resin temperature to 360℃ or more.

Limit residence in cylinder condition: 30 min x 350℃

Rear part: 290 - 300℃

Middle part: 300℃

Front part: 310℃

Nozzle: 310 - 320℃

If high flowability is required depending on the product shape, the temperature can be lowered by approximately 20℃ less than the above.

70 - 150℃

In order to improve the appearance of mold products and secure flowability, it is recommended to mold as high a mold temperature as possible.

130 - 150℃

The mold temperature greately influences the PPS physical properties.

Do not mold at a mold temperature of 120℃ or less.

40 - 100rpm

If metering is unstable, it is recommended to increase the back pressure (2.0 - 3.0MPa).

High speed injection is recommended in most cases because the LCP has a high solidification rate.

In order to achieve an excellent appearance, high-speed injection is required.

However, since warpage or burn is likely to occur, thypically a high-speed injection more than necessary is not required if the appearance becomes excellent.

The optimal injection pressure varies depending on the shape of the product, mold design, and other molding conditions, etc.

The best method is to start molding at a low pressure and gradually increase the pressure.

Almost all mold products can be molded at resin pressures of 15 to 45 MPa.

Normally, injection pressures of 30 to 100MPa are favorable, and molding at low pressures is recommended to prevent burrs.

We recommend to, first, purge with polycarbonate containing glass fibers while maintaining a molding temperature, purge with polyethylene, and repeat purging with polycarbonate containing glass fibers and polyethylene, alternately.

In addition, purging can be more effectively carried out by completely discharging a purging material in the cylinder and placing the next purging material.

In place of polycarbonate containing glass fibers, commercially-available acrylic purging materials can be used.

If molding work is suspended for 30 minutes or more, purge resin in the cylinder, and reduce the cylinder temperature by 50℃.

Before supplying pellets or turning the screw, take sufficient time for heating the cylinder so that the temperature reaches -10℃ less than the molding temperature.
