Title: Innovations by Hans Overeijnder in Plastic Pipe Extrusion

Introduction

Hans Overeijnder is a notable inventor based in Hardenberg, Netherlands. He has made significant contributions to the field of plastic pipe extrusion, holding a total of 3 patents. His work focuses on improving the manufacturing process of thermoplastic polymer pipes, particularly polyvinylchloride.

Latest Patents

Among his latest patents is an innovative apparatus for extruding a plastic pipe under controlled wall thickness. This apparatus features an extrusion die equipped with heating elements strategically located around the moulding end part. The wall thickness of the extruded pipe is meticulously controlled by measuring it at 360 points distributed evenly around the circumference. The average wall thickness is determined in eight measuring sectors, each containing 45 measuring points. By comparing the average of one measuring sector with the overall circumferential average, any deviation in wall thickness is corrected through the action of the heating elements. This method ensures that the polyvinylchloride pipe produced exhibits an even wall thickness throughout its circumference.

Career Highlights

Hans Overeijnder has worked with several companies, including Wavin B.V. His experience in the industry has allowed him to refine his techniques and contribute to advancements in plastic pipe manufacturing.
