Epoxy
casting line
Continuous metering and mixing of epoxy resin with mineral fillers — polymer concrete. Compressive strength, dimensional stability, vibration damping, chemical resistance and dielectric properties, in one material.

How the line works
All four binder systems run on one machine design. The five stages work as a single flow; what changes between configurations is the binder, the materials of the wetted parts, the temperature regime and the casting programme.
Dry component metering
Screw feeders for coarse and fine mineral filler with an active bridge-breaking device, WIKA level sensors and a replaceable filter cartridge on every hopper, so dust is not vented into the workshop.
Liquid component metering
Separate pump groups for resin and hardener: BAUTEC gear pumps, FESTO servo drives, pressure monitoring on each line, automatic recirculation when the machine stops.
Dynamic mixing head
Recirculation-type low-pressure head with a Siemens drive, a horizontal traverse unit for calibration and servicing, and automatic solvent flushing after every cycle.
Vacuum degassing
Degassing column with a BUSCH R5 rotary vane pump, residual pressure 0.1 mbar. Air entrained during mixing is removed before the mix reaches the mould.
Casting and control
Casting unit, 12″ touch panel, a frequency converter per metered component, recipe memory and remote diagnostics over WIFI.

What the epoxy line produces
Epoxy polymer concrete is bought for what cement concrete cannot give: no porosity, dimensional stability and dielectric strength.

Reference: busbar manufacturer
A Russian manufacturer of busbar trunking systems — main, distribution, lighting and trolley busbars rated from 25 A to 10 000 A — casts the insulation of its busbars on the epoxy configuration of this line.
Cast insulation is epoxy polymer concrete applied directly over the conductor. Density of the casting is the whole point: entrained air becomes a site of partial discharge and, in time, a breakdown path. The mix is therefore degassed to 0.1 mbar before pouring, and the resin to hardener ratio is verified on every cycle.
Questions and answers
What is polymer concrete?
Mineral aggregate bound by a polymer resin instead of cement. At the same aggregate it gives markedly higher compressive strength, better dimensional stability and no capillary porosity.
Why use polymer concrete for machine tool bases?
Vibration damping, several times better than cast iron, which carries straight through to surface finish and tool life. A low coefficient of thermal expansion means the machine drifts less as it warms up, and the casting needs no ageing before machining.
Why is vacuum degassing critical for cast insulation?
Voids inside the insulation become sites of partial discharge and eventually breakdown paths. Degassing to 0.1 mbar removes the air entrained during mixing before the mix reaches the mould.
How does the epoxy configuration differ from the others?
The machine design is shared. What changes is the binder system and, with it, the materials of the wetted parts, the temperature regime and the casting programme.
Is there a fixed model range and a price list?
No. Every line is engineered and built to the customer's technical specification: the unit layout, number of feeders, output and degree of automation follow the product you intend to make. The quotation is prepared once the specification is agreed.
Which countries do you supply?
