Title:
WHEEL MADE OF PLASTIC AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JPS5853501
Kind Code:
A
Abstract:
A unitary wheel is injection molded from reinforced thermoplastic material in such a manner that the melt streams of material meet and coalesce in the spokes of the wheel. This wheel has improved strength since the melt streams do not meet and coalesce in the rim portion thereby making the rim impact resistant. Coalescence of the melt streams in the spokes of the wheel is accomplished by introducing the streams into certain of the spokes while separating those spokes from each other by an odd number of intermediary spokes to which no material is directly injected.
