Problems solved by technology

[0002] In vitro diagnostic consumables such as pipette tips, vacuum blood collection tube caps, centrifuge tubes, cryotubes, PCR tubes, etc. are usually disposable consumables. With the rapid development of in vitro diagnostic technology, the demand for in vitro diagnostic consumables is also increasing. Therefore, there are new requirements for rapid prototyping of products. At present, these consumables are usually injection molded. Due to the limitation of the performance of injection molding raw materials, the cooling and plasticizing time is longer, which makes the molding time of the product longer and the molding efficiency is lower. It is difficult to meet the requirements. Demand for mass and rapid production
