The NET-Technology®

The central element of NET-Technology® is a specially developed refractory fabric mesh, which is reliably inserted between the riser and the casting. After the casting has solidified, this fabric becomes a predetermined breaking point of the riser neck, allowing riser rests to be reliably removed from the casting with minimal effort and eliminating the risk to surface quality. Savings will be realized with reduced cleaning times and improvements in casting throughput. Reductions in labor and auxiliary equipment are significant, with fewer casting rejections. During the development of NET-Technology® the product portfolio was enhanced with solutions developed for all applications, which are compatible with all types of hand and machine molding and can be utilized with all types of binder. Learn more in our NET-Technology® brochure.

Overview NET-Technology®

NET-Technology® product film

Advantages at a glance

Reduced cleaning costs
Less scrap
Knock off up to 450 mm
Significant time savings
Reduced risk of injury

Simply knock off, no cutting required,
riser removal and grinding

With the use of NET-Technology® products significantly reduces both the grinding time and the total processing time required for each casting. The risk of rejection due to breaking-in defects is eliminated with mechanical stresses introduced to the casting through impact during riser removal, minimizing the subsequent risk of casting failure due to cracking.

Case study NETFrame® – hydraulic component

“By using the NETFrame® technology from GTP Schäfer we are able to significantly reduce our processing times for demanding castings that traditionally involve extended cleaning times. Riser removal is facilitated within the normal process, eliminating the requirement for separate cutting operations. Furthermore, our rejection rate for breaking-in defects has significantly reduced.“

Case study NETCore® – wind power component (rotor)

“With NETCore®, we can reliably feed particularly difficult-to-access feeder positions and also significantly improve cleaning times and results.”

Case study NETSleeve® – machine component

“Since the integration of NETSleeve® technology in our hand molding process the ease in which large castings pass through the cleaning department has improved, with time the time taken for riser removal considerably reduced, this has allowed us to increase the throughput of castings by 100%“

Case study NETCore® – flange

“The use of NETCore® technology enables us to handle very high thermally stressed (thick-walled) components made of GJS within the regular throughput time and without removing the castings from the regular production process. Furthermore, the throughput time in the finishing area is minimized due to greatly reduced grinding work at the feeder neck“.

Case study NETCore® – frames

“The use of NETCore® technology enables us to produce sophisticated components within the regular lead time and without having to deviate from the regular production process. Furthermore, the reject rate is clearly reduced.“

NETFrame®
Increased efficiency for foundries

The NETFrame® product line was specially developed for the reliable, efficient removal of gate and side feeder systems. The products make it possible to define and create a predetermined breaking point directly on the casting surface.

NETCore®
Breaking edge “0” for large castings

The NETCore® breaker core technology was specially developed for the reliable removal of high-modulus risers that have cross-sectional contact areas on the casting with the aim of eliminating cutting and grinding operations.

NETSleeve®
Maximum feeder power for the largest possible module

NETSleeve® was specially developed to achieve the largest possible module when using risers or sleeves without the need for specially designed breaker cores or metal sheets. The technology makes it possible to efficiently remove risers from the casting with a minimum of cutting and grinding.
