Leading in the field of electro permanent magnet technology THE HIGHEST SAFETY STANDARD 1 CLOSED MOULD DETECTION The MAG cycle can only be performed when a build-up of pressure is detected. This ensures that both mould halves fit 100% against the respective magnet plates when the MAG cycle is performed. MAGNETIC FLUX DETECTION Release for production is only obtained if the measured magnetic flux, after magnetization, reaches the standard minimum safety value. If this is not the case, an error is indicated. If during the injection process the magnetic flux value decreases minimally, the...

Leading in the field of electro permanent magnet technology STRENGTH OF MAGNETIC CLAMPING DISADVANTAGES OF CONVENTIONAL CLAMPING / 1 Limitations and no flexibility The maximum size of the mould is limited because of the clamps. Time consuming and ineffective Due to the thin base plate, many clamping tools are required. No uniform clamping The mould is not clamped where most forces occur (moulding part), resulting in mould deformation = wear of the mould + lower quality of the injected parts. BENEFITS OF MAGNETIC CLAMPING / 4 Bigger moulds on smaller machines The complete area of the machine...

MAGNETIC CLAMPING VS CONVENTIONAL CLAMPING CONTEXT TRADITIONAL CLAMPING MECHANICAL CLAMPING HYDRAULIC CLAMPING HQMC MAGNETIC CLAMPING Serious safety risk caused by mechanical point clamping. The effective clamping force is based on point clamping and cannot be accurately determined. In addition, hydraulic components require continuous inspection and maintenance. MOULD CHANGE EFFICIENCY Changing the mould is time consuming. The thickness of the mould backplate is limited, and therefor causes a much less efficient mould change time. The mould change time can be shortened to a few minutes,...

Leading in the field of electro permanent magnet technology APPLICATION CASES

ELECTRICAL PERMANENT MAGNETIC QUICK CHANGE SYSTEM FOR PUNCHING PRESSES EFFICIENCY Changing dies on punching machines is a timeconsuming activity. This increases production costs and decreases efficiency. By using the HVR magnet quick-change systems, set-up time is minimized, overall production costs are reduced, and competitiveness is enhanced. STABILITY With the HVR magnet system, any mould can be clamped, regardless of its size and shape. This reduces the design and production costs of the tool. A uniform clamping ensures a longer lifespan of the punch / cutting plate and guarantees a...
