Abstract

The paddling fixture in the form of a polypropylene chair with a centerboard for surfboards is produced as a single-piece item by an injection molding process. It is toughened against ultraviolet radiation, and is painted with conventional cadmium-free paint. The fixture increases stability of the surfboard, and allows it to be used as a canoe.

Description

Lösungsweg zur Herstellung eines Stuhlaufsatzes mit Schwert für ein Surfbrett:
Allgemein gilt, daß sich die Form an der schon auf dem Markt befindlichen Modellen orientiert. Dies hat zur Folge, daß es sich anbietet bei einem Hersteller von handelsüblichen Stapelstühlen dieses Produkt zu fertigen. Da die Form bereits als Werkzeug vorliegt, ist eine Veränderung, bzw. eine Umarbeitung einfach möglich. Es werden für die Herstellung zwei Fertigungswege angeboten, da eine Fertigung auf Spritzgußmaschinen nur bei einer Stückzahl < 2000 Stück rationell möglich ist.Solution for producing a chair attachment with a sword for a surfboard:
In general, the shape is based on the models already on the market. As a result, it makes sense to manufacture this product at a manufacturer of commercially available stacking chairs. Since the form is already available as a tool, it is easy to change or rework it. Two production methods are offered for the production, since production on injection molding machines is only rationally possible with a quantity of <2000 pieces.

Material: Polypropylen (PP-A Formmasse für Extrusion, MFI 190/5 = 0,5, mit Lichtstabilisator PP-A-E-005-LS DIN 16774) für Spritzguß modifiziert, UV-stabilisiert und mit handelsüblichen cadmiumfreien Farbstoffen eingefärbt.Material: polypropylene (PP-A molding compound for extrusion, MFI 190/5 = 0.5, with light stabilizer PP-A-E-005-LS DIN 16774) modified for injection molding, UV stabilized and with commercially available cadmium-free dyes colored.
