Product catalog summary

Specifications:
The document details the specifications for venting plugs and valves used in injection moulds, including material types such as steel and stainless sintered metal, along with their hardness ratings and resistance properties.

Procedures:
Procedures for adjusting and cleaning venting slots are outlined. Adjustments can be made by altering the diameter or installation depth, and cleaning is done using metal foil. Grinding or polishing is recommended for certain lengths, and burrs must be removed.

Standards and Recommendations:
For Z 137 steel venting plugs, air escapes through the outer surface and slots. For Z 139 stainless sintered metal plugs, grinding or polishing is discouraged to avoid clogging pores. Height adjustments should be done by spark erosion, accounting for a settling of 0.1–0.2 mm due to injection pressure.

Key Data from Tables and Graphs:
Tables provide dimensions and material properties, such as filter fineness (10µm) and shearing strength (300 N/mm²). A graph shows the relationship between pressure difference and flow rate for Z 139 venting plugs.

Critical Information:
Venting plugs are essential for optimal venting of mould cavities. Proper maintenance is crucial to prevent clogging and ensure efficient operation. The document also highlights the material resistance to various substances, ensuring durability in different environments.
