APPARATUS FOR MANUFACTURING HEXAGONAL HONEYCOMB STRUCTURED BLOCKS AND PLATES MADE OF THERMOPLASTIC PLASTIC MATERIAL USING INTERNAL WELDING PRINCIPLE

摘要

PURPOSE: An apparatus for manufacturing hexagonal honeycomb structured blocks and plates made of thermoplastic plastic material is provided to achieve high quality of products and increase operational reliability through the application of internal welding principle in addition to external welding. CONSTITUTION: The blocks and plates manufacturing apparatus comprises: a welding device(1) to weld plastic strip sections into HOBE(honeycomb before expansion) strands(2); a heating device(3) to heat the HOBE strands up to a welding temperature; an extension device(4) to extend the HOBE strands; and a cutting device(56) to cut the HOBE strands into blocks(5) or folded plates(5a,5b,5c).
