Abstract

The invention discloses a dumbbell and barbell weight stack manufacturing process and a weight stack thereof. The process comprises the steps of preparing a middle core sleeve, processing a metal outer cover, covering a soft protective shell and the like. The middle core sleeve of the weight stack is formed by integrating the metal outer cover and mineral substances through hydraulic processing, and the soft protective shell is covered, so that the weight stack manufacturing process is environment-friendly and economical; the weight stack product is not broken and deformed in the using process, so that the service life of the product is prolonged, and the damage to the ground, floor or floor tile surface is small; and the soft protective shell has a certain sound reduction effect on noisegenerated during use.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a production process of weight plates for dumbbells and barbells and the weight plates thereof. Background technique [0002] Currently, there are a variety of weight stack products available on the market for dumbbells and barbells. Most dumbbells and barbell weights can be divided into two types: one is plastic dumbbells and barbells, which are low-end products, and the other is made of dumbbells and barbells. Weight plates, these products are high-end products in this field. [0003] When low-end dumbbells and barbell weight plates are made, the outer material is made of plastic, and the inside is filled with cement. During the production process of this product, a large amount of acidic liquid needs to be used to clean the cement stains on the outer plastic surface, and a large amount of sewage generated during the cleaning process will seriously pollute the enviro...
