Magistretti | Mass Production of Plastic: The Single-Injection Chair

A full-plastic stacking chair, injection molded in one piece from polypropylene, with the seat, backrest, and four legs all integrated. Due to demolding requirements, all surfaces have a slight draft angle, and all corners are rounded, with no sharp edges. The seat has regularly arranged drainage holes, which also serve to reduce weight and material. The chair legs have an L-shaped or cross-shaped cross-section instead of being solid, achieving rigidity through shape rather than thickness. The surface is a matte single color, showing extremely fine mold texture and a parting line. Stackable. Pure white background.
Avoid: visible seams or screws, sharp corners, solid cylindrical chair legs, high-gloss surface.

一張全塑料的堆疊椅,由聚丙烯一次射出成型,座面、椅背與四支腿全部一體。因為要脫模,所有的面都有微小的拔模斜度,轉角都是圓的,沒有一處銳角。座面有規則排列的排水孔,同時也是減重與減料。椅腿的斷面是 L 形或十字形而不是實心,靠形狀而不是厚度取得剛性。表面是霧面的單一顏色,可以看見極細的模具紋理與一條分模線。可堆疊。純白背景。避免:出現接縫或螺絲、轉角做成銳角、椅腿做成實心圓柱、表面做成高光澤。
