September 03 15:06:14, 2022

Extrusion processing is one of the inner hole finishing methods. It uses a pressing tool whose tool diameter is slightly larger than the diameter to be processed and has a higher hardness, forcibly passing through the pre-machined hole to plastically deform the metal of the surface layer of the hole wall. The method of achieving the required dimensional accuracy of the workpiece is shown in Figure 1. In addition to the characteristics of high work efficiency, process stability, precision and surface roughness (usually up to IT7~IT6 accuracy and R_00.8~R_00.2), extrusion processing can also be corrected to a certain extent. Hole shape, changing the pore size and strengthening the surface.

Culture flask

According to the adherence requirements of the product, cells are divided into three categories:

Suitable for suspension culture of common cells and tissues;

The standard type has good cell adhesion performance and is suitable for cell adhesion growth;

Dedicated containing cell pastes (cell clusters that can be used in some special cases, such as cell walls, cell surfaces and secretory cells).

According to the shape of the instrument, it is divided into:

Wide body culture flask;

triangle bottle;

Torticollis flask.
