About HEMAtec Werkzeugbau
HEMAtec Werkzeugbau from Herford develops, manufactures, repairs and maintains injection molding, die casting and LSR tools – from simple to complex unscrewing tools. The range of services includes part and tool design with CAD/CAM, simulation and digital twin, project management as well as maintenance, repairs and corrections also for externally manufactured molds. In-house manufacturing uses 5-axis HSC milling, sink EDM, surface grinding and high-speed radial drilling; surface treatment is carried out by sandblasting, polishing and laser engraving. A proprietary process is the coating of cooling channels from diameter 0.8 mm for corrosion protection and for variothermal tools. The offering is complemented by L.A.R.S., a proprietary servo drive system for unscrewing technology. More than 53 companies from various industries trust this toolmaker; standard projects reach production maturity within 30–40 working days.

Materials & Processes
Tool steel
Material for injection molding, die casting and LSR tools as well as cavities, cooling channels and fitting surfaces.
5-axis HSC milling
High-precision machining of delicate contours, tight tolerances and demanding cavities (Röders RXP600 DSH with automation).
Sink EDM
Finest geometries and surfaces that cannot be achieved by machining (OPS Ingersoll G80 Competition).
Surface grinding
Flat, high-precision surfaces with tight dimensional tolerance and high repeatability (Ziersch Z24).
High-speed radial drilling
Precise drilling for tool cooling, threads and various drilling tasks (Donau DR23).
Cooling channel coating
Protects cooling bores from diameter 0.8 mm, prevents deposits, secures cooling performance and is suitable for variothermal tools.
L.A.R.S. servo drive system
Proprietary system for unscrewing technology with adjustable torque monitoring and precise travel adjustments.
Polishing in mold making
Essential step in mold making that significantly influences the quality of the molded part.
Sandblasting
Clean, uniform surface appearance for functional and optical requirements (EB.S. 6545 Classic).
Laser engraving
Serial numbers, logos and markings on tools.
