With a total of 4 patents to his name, Heathe's work has had a profound impact on the efficiency and effectiveness of plastic manufacturing.

Latest Patents

One of his latest patents is the "Double Wave Screw." This innovative plasticating screw features an improved mixing capability for polymer blends. It comprises a feed zone with a helical flight that defines a solid material feed path, a compression zone for converting solid material into molten material with a helical channel of variable depth, and a waved melting zone that breaks up solid agglomerations while distributing them equally in the liquid melt. Additionally, it includes a spiral mixing zone that traps large agglomerations and contaminants, along with a second melting zone for completing the melting process and creating a substantially homogeneous melt. Furthermore, he has developed a method for mixing plastic material that has been at least partially plasticized and contains inhomogeneities.

Another significant patent is the "Valve Assembly for Injection Molding Machine." This improved check valve assembly includes a cylindrical barrel and a rotating and reciprocating plasticizing feed screw. The screw feeds heated thermoplastic material to a screw tip, which then feeds the material externally. The check valve assembly, located between the feed screw and the screw tip, features a sliding ring inside the barrel. This ring has a first sealing surface that can block communication between the feed screw and screw tip, ensuring efficient operation.
