Knowledge base

We use roller cutting with diamond or carbide rollers, in some cases, crystal cutting can be used. The cutting tool makes a "scratch" on the glass, which then breaks the glass.

Maximum format is 2000×1500 mm. Standard thicknesses are 2–8 mm. Under 2 mm (down to 0.55 mm) and above 8 mm are special projects. Straight and shaped cuts are available.

Two routes: a manual machine where nothing else works; or a 5-axis CNC for grinding/polishing, drilling, and milling. Thickness and format limits match cutting.

Cutting runs on a computerized CNC machine. Cutting accuracy is ±1 mm.

Yes, that is possible.

Yes. Cutting can be a separate service or the first stage of a complete route at the Octoglass site. However, we warn you that glass without edge treatment (grinding or polishing) contains stress zones after breaking along the cutting line and may spontaneously collapse, for example, during transportation. Additionally, it should be borne in mind that in the process of breaking glass along the cutting line, cracks and small chips may remain on the glass, which it is also desirable to remove by processing the edge.

Glass washing is possible only after full processing of all edges and holes, because unprocessed edges damage the washing rollers.

Transparent and reflective surfaces need a case-by-case review: surface prep and capture method depend on the part. Send photos and the goal — we will advise whether scanning is feasible.

Typically the object itself, photos, approximate size, and a clear goal: 1:1 reproduction, adaptation, or mold/tooling prep.

Three tracks: custom chemical synthesis, overseas supply to your specification, and propylene carbonate purification on Octoglass equipment. Propylene carbonate is typically in stock; the minimum batch is from 1 litre.

Purified propylene carbonate (CAS 108-32-7) is kept in stock and purified on our own equipment. Confirm volume and ship timing for a specific batch when you enquire — especially for larger volumes.

The minimum batch is from 1 litre. Depending on volume, we supply in amber bottles, with sieves, hermetically sealed.

No. The heater is the transparent FTO coating itself. Metal current busbars run only along the glass edge and can be concealed by the product frame.

The glass does not need to be heated to a high temperature. The main goal is to keep its surface slightly above the dew point of the surrounding air.

Yes. Heating can be regulated by an electronic controller based on glass temperature, air temperature, and humidity.

Technically FTO glass is a resistive load, but voltage depends on the resistance of the specific pane. For new developments Octoglass recommends considering low-voltage 24 or 48 V DC systems.

A point contact creates uneven current distribution and local heating. That is why a distributed conductive busbar along the glass edge is used.

Yes. For refrigerated and freezer display cases this is the main recommended option. The FTO coating is located inside a sealed insulating glass unit.

Yes. Product geometry, current busbars, and operating power are calculated individually.

Yes. A dedicated controller can be used, or control can come from the equipment automation.

Preferred. Broken glass can work if the overall shape remains, or mirroring of the surviving side may be used. Without a usable original, geometry reconstruction is possible as a special project: drawings and models are required, and several iterations may be needed.

Laminated glass. Functions from the Octoglass laminated-glazing range can be included — within what fits the specific geometry.

Make and model, glass type, photos of the opening/sample, and whether an original exists for scanning. If lamination functions are needed, note them up front.

For owners and workshops where serial glass is unavailable or too expensive: classic restoration, custom projects, cars, watercraft, and other vehicles.

For automotive use we make tooling for both side glass and windshields. For oversized glazing — for example, bus glass — send an enquiry and we will assess fit separately.

A mold sees repeated heating and cooling and can drift over time — how much depends on the bending program. A metal counterpart lets you periodically check that the tooling still holds the agreed geometry and catch deviation from nominal in time.

Every glazing manufacturer works to its own tolerances. If you copy non-original glass, the OEM’s tolerances stack with those of the non-original part — and the finished tooling can deviate substantially from the true original geometry. For automotive work AO Octoglass recommends starting from original glass.

Yes. With a 3D model or flat drawings we prepare working documentation and then run metalworking, assembly, dressing, and annealing. An original is needed when the goal is to reproduce an existing part with minimal tolerance stack-up.

Original glass, a 3D model, or flat drawings; a short note on the tooling’s purpose and critical fit. Say whether you need a metal counterpart for periodic geometry checks and whether bending will run on the Octoglass site.

Making electrochromic glass needs a high production culture — quality requirements are roughly two orders of magnitude stricter than the industry average. Assessment checks site readiness before a license decision.

It is a separate path that needs expensive PVD R2R equipment. Estimated deployment cost is about USD 50–60 million.

A technology package, product-range models and drawings, training at Octoglass plants, technical and process support, and training polymer for the first products. Products are subject to royalty.

The estimated cost starts from RUB 15,000,000. About 85% of operations are covered by typical glass-processor equipment; the final figure depends on assessment and route.

Briefly describe the plant, equipment fleet, target path (organic polymer or hybrid inorganic EC), and launch horizon. The exact list is refined at assessment.

Gravity bending on CNC-controlled furnaces. Temperature and the cycle program are monitored online; tooling geometry is checked after every cycle.

Yes. Alongside glass bending we form plastic — terms and route are agreed per project.

Glass up to 2500×1500 mm, thicknesses from 2 to 8 mm. Under 2 mm is available on special order when the design and tooling allow.

A drawing, model, or sample; size up to 2500×1500 mm; glass thickness (typically 2–8 mm, thinner on special order); whether tooling exists or must be made; and any follow-on stage (edge work, faceting, lamination).

Yes. We laminate both flat and bent glass — within the agreed format and thickness.

Baseline routes are EVA and ionoplast. PVB and TPU are available as separate non-standard projects — terms are agreed separately.

Format up to 2500×1500 mm. Typical glass is 2 mm; we laminate glass up to 15 mm thick. Above 8 mm thickness is a special project. We laminate both flat and bent glass.

Yes. High-throughput equipment delivers quality lamination for small lots and one-off parts. Packages are assembled in G3 clean rooms.

Overall size (up to 2500×1500 mm), flat or bent glass, thickness, interlayer type (EVA/ionoplast; PVB and TPU as separate projects), package stack-up, and lot size. Noting the next stage after lamination also helps.

It means small-series production: manufacturing a limited lot of an agreed technology at Octoglass after development or adaptation of the solution.

Electrochromic systems, glass products, and glass processing — backed by in-house R&D and a production base.

Briefly describe the task, share available inputs (brief, drawings, samples), and state the expected outcome: report, prototype, pilot, or small-series production.
