## How the line works

One machine design serves all four binder systems. Five stages in a single flow:

01. **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.
02. **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.
03. **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.
04. **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.
05. **Casting and control** — Casting unit, 12″ touch panel, a frequency converter per metered component, recipe memory and remote diagnostics over WIFI.

## Applications

Solid Surface sheet 3–12 mm, Worktops with integrated basin, Vessel basins, Floor-standing basins, Bathtubs, Stone slabs, Wall panels, Façade panels, Reception desks, Backlit mirrors.

## Reference installation

The acrylic configuration of this line casts the sheet from which a premium sanitaryware range is made: worktops with integrated basins, floor-standing and vessel basins, bathtubs and backlit mirrors. The plant belongs to the equipment manufacturer and runs the full cycle, from filler charging to the finished article.Because the acrylic and polyester configurations share the same machine design, an operator trained on one moves to the other without retraining on the metering, mixing and degassing units.

## Questions and answers

**What exactly is Solid Surface?**

A cast composite that is homogeneous through its full thickness: mineral filler bound by a polymer binder, with no coating or gel coat on top. A scratch can be sanded out because the material under the surface is the same material.

**Why acrylic rather than polyester?**

Acrylic holds colour better, absorbs less water and can be thermoformed. Polyester is harder at the surface, more chemically and fire resistant, and cheaper. Both are used for Solid Surface; the choice follows the market and the investment you plan.

**Why does the grade of alumina trihydrate matter?**

It governs both colour and matrix flow. Grades coated with titanium dioxide are used for light solid colours, neutral grades for dark ones, and silane-coated grades where adhesion to the resin and low moisture uptake matter. Coarser particles lower viscosity and improve wetting.

**Can one line run several colours?**

Yes. Recipes are held in the controller, and the polyester configuration additionally supports up to four colour lines at once. Different chips have different viscosities, so each colour is a separate recipe rather than a variation of one.

**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?**

China, India, the Middle East, the CIS and Russia. Correspondence and documentation in English or Russian; the control software interface is supplied in the language agreed for the project.

**Who manufactures the equipment?**

SARMATECH LLC, Leningrad Oblast, Russia, established 1998. The machines carry the AUTOCASTER® mark; the line and its control software carry the POLYBLENDER® mark.

## Commercial terms
