How Black Diamond Creates Carabiners

Black Diamond on creating carabiners

I always find articles and videos on how climbing gear is constructed quite fascinating. A couple months ago I posted a video on how DMM makes carabiners and now has written an article on Black Diamond‘s process of making carabiners from start to finish.

“Whenever you design something, it starts with a need,” says Bill Belcourt, BD??s Climbing Hardgoods Category Director. The BD carabiner that eventually ends up on a climber??s rack begins as a brainstorming session or a simply sketched idea in the design department. Product designers determine what they want the carabiner to do and look like, and from there, they design computer models. Before they physically make anything, the design team uses FEA (Finite Element Analysis), which helps determine the shapes, angles, and features needed to fulfill the company??s strength requirements.

    it looks like they cold-forge them instead of hot forging that DMM uses? i know nothing of metallurgy so correct me if im wrong. Which is better?

    têtes de poisson ont une sorte de mauvaise réputation. Ils ne sont pas les filets lisses, pas même des steaks brut. Mais ils ont des usages. Quand j’étais enfant, ma grand-mère aimait à faire une sorte de tête de ragoût de poisson. Elle l’a fait chaque fois que nous lui avons apporté un peu de saumon. En fait, elle a expressément demandé la tête, le dos, la graisse du ventre, et tout ce que nous ne voulions pas immédiatement. Il était bon, copieux ragoût, mais, comme sa recette a été adaptée à partir des recettes transmises de génération en génération, et l’idée derrière eux était d’utiliser aussi peu d’ingrédients que possible pour obtenir le maximum de valeur de poissons, il manquait un petit quelque chose.

    Bien ajust茅 votre poche pour stomie est important pour 茅viter les irritations et les fuites potentielles. La plaquette de la stomie est une composante essentielle du syst猫me de poche, qui forme une barri猫re efficace entre votre peau et la sortie de la stomie qui, autrement, peuvent cr茅er des probl猫mes de peau. Soci茅t茅s de fournitures m茅dicales offrent diff茅rentes tailles et un choix d’un syst猫me d’une seule pi猫ce de stomie (de la plaquette et la poche en un) ou un syst猫me 脿 deux pi猫ces avec la plaquette et la poche en deux composants distincts.
