Metal mold with cadre

When suspension suppositories are molded in a composite metal mold with cadre, the entire mass is poured out over the mold at once. An excess of mass is needed to be able to divide the mass quickly enough over all cavities before the active substance settles. 

After the active substance and excipients have been dispersed in and completely mixed with the suppository base the mass should be poured into the molds. The molds can be filled serially (one by one) or simultaneously (all cavities at once). For serial filling usually plastic strips are used (Fig. 11.3). When using a composite metal mold with cadre or a bearer with a number of strips, 100 cavities can be filled simultaneously. Such metal molds are composed of 10 elements of 10 cavities. Once fixed together a cadre is placed over the mold (Fig. 11.6) and aU the mass is poured out at once.

Filling a composite metal mold with cadre the pouring temperature is chosen just high enough to prevent solidification before aU cavities are filled 34—35 °C will usually do.
