Abstract
A method of sealing an article by heating solid plastic material in a chamber into a flowable state and then forcing the material from the chamber into a reservoir in a manually portable device. While in the reservoir, the material is maintained homogeneously molten and flowable and the material is forced from the reservoir into a mould cavity at a sufficiently fast rate to fill the cavity before flow passages into the cavity become blocked with hardening material.
