Ceramic plants control quality at three points: the raw slip, the fired body and the glaze. For each stage the right instrument is different. We act as porcelains and ceramics testing instruments manufacturers in India for these stages, and our suppliers in India network ships to tableware factories, insulator works and sanitaryware units.
Start at the wet end. The slip viscosity and casting rate apparatus and the particle size and sedimentation analyser help keep casting and filter-press slips consistent. For firing, the programmable pyrometric cone furnace and the dilatometer reveal shrinkage, expansion and glaze fit.
Finished ware is judged on strength, impact, glaze quality and safety. The four-point flexural machine and the impact pendulum cover mechanical performance, the Mohs scratch set and the thermal shock and autoclave system examine glaze, and the lead and cadmium release set verifies food-contact safety. Porcelain insulator makers add the large cantilever and tension machine for line-hardware qualification.

The tile and marble range focuses on flat floor and wall surfacing and tests such as slip resistance, deep abrasion and modulus of rupture of tiles. This porcelain and ceramics range covers the manufacturing process and shaped ware, from slip viscosity and dilatometry to tableware impact, food-contact safety and electrical porcelain insulators. A plant making vitrified tiles uses the tile page, while a crockery or insulator works reads this one.

The complete Porcelains and Ceramics Testing Instruments range (10 products), in alphabetical order:
Check the maximum temperature against your firing range, the sample length accepted, the resolution of the LVDT, the heating rate options and whether the software calculates the expansion coefficient automatically. Reference standards for calibration and the furnace atmosphere matter when you want to compare body and glaze expansion for fit.
Ceramic specimens are brittle, so load capacity is smaller but alignment is critical. Look for a four-point fixture with articulating rollers, low-friction supports, smooth load control and a peak hold display. Confirm the bar and tile sizes you test, and whether you need fixtures for different spans.
The set covers glassware, racks, a dark cabinet, acetic acid solution and a means of analysis, which is usually atomic absorption or ICP at an analytical lab. Clarify the standard you follow for tableware and the maximum volume of ware, since the extraction is done at room temperature for a set period.
Crockery and tableware plants, sanitaryware and washbasin manufacturers, high-voltage porcelain insulator works, refractory and technical ceramic producers, glaze and frit suppliers, and ceramic research labs buy these instruments. A new plant normally purchases slip control and flexural strength tools first, adds firing behaviour instruments, and then invests in glaze safety and large insulator test machines where products demand it.
Yes. We manufacture and supply to ceramic clusters in India and overseas customers. Mention the products you make, the standards you test to and the voltage at your site so the quotation is complete.
Small cones made of ceramic mixtures soften and bend at a known combination of temperature and time. Placing them in a furnace tells you the heat-work actually received, which is more informative than the thermocouple reading alone. The programmable furnace lets labs repeat firing profiles.
Crazing occurs when the glaze is under tension because its thermal expansion is greater than that of the body. A dilatometer measures both, so a technician can adjust glaze composition or body recipe. The autoclave test then verifies the fit under steam pressure.
This depends on the frame rating, which is chosen from the maximum cantilever or tension load of your insulator type. Please provide the voltage class, dimensions and test loads, so we can propose a frame, fixtures and safety enclosure.
Yes. Wet analysis items need water and a fume arrangement, furnaces need ventilation, and large machines need a floor base. We include a basic utility and layout note with the quotation when you list the instruments of interest.
