Moulding

ARPRO 5160 can be molded using Crack Fill (CF) and Pressure Fill (PF):
Crack fill: preferably applied to Pre-Treated (PT) or Non-Pre-Treated (NPT) ARPRO.
Pressure fill: applied to either Pre-Treated (PT) or Non-Pre-Treated (NPT) ARPRO.

Pre-treatment

Recommended pre-treatment cycle with pressure tank environment and incoming compressed air both at 23°C:
1 hour up to 1.5 bar, hold for 2 hours at 1.5 bar,  decrease and maintain at 0.4 bar throughout production.

Pre-treatment cycles can be adapted according to molding process, density and part geometry:
If internal cell pressure is too high, this may lead to fusion issues. In this case, decrease time, pressure or temperature to improve fusion.
Increase time, pressure or temperature to reduce molded density and improve aspect.
Operating the pressure tank above ambient temperature, up to a maximum of 50°C, significantly shortens pre-treatment time.

Post-treatment

No post-treatment is required. Stabilization to ambient conditions for 4 hours before dimensional quality testing is recommended. For highly compressed parts, post-treatment is compulsory to obtain a nice surface aspect, for example 3 to 8 hours at a temperature of 80°C.

Shrinkage

Typical values range from 1.8% to 2.2%. The higher the molded density, typically the lower the shrinkage.

Storage & Handling

Storage

A storage temperature above 15°C is strongly recommended.
Indoor storage strongly recommended.
If stored outdoors, it is strongly recommended to keep the material indoors for 24 hours before molding.
