The matrices are a fundamental part of the technological process of plastic forming. In Sermocol we produce several types of matrices, such as:
- Open Extrusion Dies to dot,
- Closed Extrusion Dies,
- Right Hole Dies,
The matrices can be produced in:
- Hard metal,
- Steel and hard metal,
The tools are produced according to the client’s drawing. The qualities of material and the ideal selection of the grade of carbide suitable for the application of the tool are guaranteed. In order to ensure a longer tool life and service life, specific coatings may be applied to the intended application.
Sermocol guarantees dimensional tolerances of ± 0.005mm and surface finishes with Ra≥0.06.
Closed Extrusion Dies
Closed extrusion dies are used in different applications and in various industries, such as the cold forging industry.
Open Extrusion Dies to dot
Open extrusion dies are used in different applications and in various industries, such as the cold forging industry, in particular for the execution of the screw joint.
Right Hole Dies
Right-bore dies are used in different applications and in various industries, such as the cold-forging industry, in particular for the wire calibration prior to bolt execution.
According to the experience and technology of Sermocol we advise:
- Selection of steel with mechanical properties suitable for the application to the shell and adequate selection of special carbide grades for a specific application by implementing air / oil outlets on parts to reduce internal pressure;
- Finishing: Polished before and after coating;
- Assembly: to guarantee dimensional tolerances of 0.005mm, assembly and execution is guaranteed by Sermocol;
