Encapsulated magnet for magnetic drive pumps |
摘要 |
<p>An encapsulated magnet assembly has a magnet (12) encapsulated during a two-step moulding process. The first step includes moulding a first moulded section (30) over a magnet assembly. The second step of the process includes moulding a second moulded section (70) over the magnet and the first moulded section in such a manner that the entire magnet is covered by the two moulded sections completely. A first parting line (74) is defined between the first and second moulded sections along an elongate tapered section of the first moulded section at the one end of the assembly. A second parting line (76) is defined between the first and second moulded sections at a dovetail on the first moulded section. An outwardly tapered surface is provided on the dovetail. The two parting lines (74, 76) define leak-free seams between the two moulded sections (30, 70), thereby sealingly encapsulating the magnet within the two moulded sections. <IMAGE></p> |
