NETFrame® – easy riser removal
Operation
NETFrame® products utilize a high-temperature refractory mesh that is rigidly clamped into a specially designed metal frame. Due to the enhanced shape of the frame, it “grips” into the molding sand and fixes the NETFrame® in the mold, preventing movement, directly at the mold face against the casting surface.
The refractory mesh introduces a cleavage plane within the in-gate or riser neck area, effectively weakening the material. At this predetermined breaking point, the remaining riser or in-gate can be easily and reliably removed with minimal force, improving process efficiency by obviating the need for grinding or cutting.
Advantages of NETFrame®
Efficient, precise
finishing for perfect castings
- Reliable molding process
- Defined predetermined breaking point directly at the casting surface
- No safety distance between mesh and casting required
- Flexible application with 40–150 mm diameter
- Reduced mechanical load on the components
- Less scrap due to cleaning errors
- process reliability and work safety
A comparison of processing steps
This example calculation shows how much time can be saved by using NETFrame® on the smallest model (NF1 – riser neck 50 x 40 mm).
