Description

Technical Field

[0001] The utility model relates to the technical field of medical product production, specifically a device for producing plastic particles of medical products. Background Art

[0002] Medical supplies include disposable syringes, which are disposable injectors made of high molecular weight polypropylene material and are divided into three-piece and two-piece types.
