NAITRON Advances Granite Composite Sink Manufacturing with TMT Technology

HUBEI, China, Sept. 28, 2026 /CourierPR/ -- NAITRON, a professional granite composite sink manufacturer based in Hubei, China, has advanced its production capabilities through the integration of patented TMT (Thermosetting Molding Technology) and digitally controlled manufacturing processes. This innovative approach ensures consistent quality and scalable production, making NAITRON a trusted partner for international distributors and wholesalers.

NAITRON has developed an intelligent molding system specifically for granite composite sinks. This system, controlled through a PLC (Programmable Logic Controller) system, features automated material dosing and an independent temperature management system. The automated process helps reduce labor costs and human error, while maintaining stable product quality. The company's patented TMT technology ensures that particles are evenly distributed across both the surface and reverse side of the sink, contributing to the overall quality and durability of the product.

Each sink is formed as an integral whole through a single compression molding process, eliminating joints or spliced sections. This method helps prevent deformation and cracking during normal use, enhancing the longevity and reliability of the product. NAITRON's granite composite sinks are designed for everyday kitchen conditions, including heat, impact, food residue, and frequent cleaning. The products use quartz-based composite materials, which contribute to a surface density and structural continuity required for daily use.

The sinks achieve a surface hardness of no less than 60 Barcol and can withstand the impact of a 225-gram steel ball in a one-meter free fall without cracking. They are designed to tolerate temperatures up to 280°C, including brief contact with hot cookware, boiling liquids, and hot oil. The quartz-based composite material resists acid and alkali corrosion and does not rust. Color quartz sand treated through a high-temperature process is intended to retain its color over time, and the resulting dense surface helps limit staining and oil residue, allowing routine cleaning without specialized detergents.

NAITRON's sinks have been recognized by China's National Center for Testing of Chemical Building Materials for their product performance. The sinks contain no toxic substances, radiation, or heavy metals. Silver-ion antibacterial agents are incorporated into the material to support a more hygienic kitchen environment.

NAITRON operates a two-phase production base with a total construction area of 80,000 square meters. With a total investment of more than RMB 100 million, the production base includes nine standard factories, four production lines, and more than 200 production and testing machines. This infrastructure supports both flexible OEM and ODM manufacturing and large-scale production and delivery. The company uses fully mechanized and automated equipment for mass production, enabling higher output and more stable quality control while reducing labor costs and the potential for human error. The combination of automated machinery and continuous production lines supports consistent manufacturing efficiency for high-volume orders.

As part of its efforts to support low-carbon and sustainable development, NAITRON has built its own photovoltaic power system, with 80% of the electricity used for production coming from clean solar energy. The large-scale use of solar power helps reduce electricity costs, contributing to more competitive product pricing for customers.

NAITRON is a National High-Tech Enterprise, holding 53 patents and boasting an annual production capacity of 600,000 granite composite sinks. Certified by ISO 9001, CE, and CUPC, and audited to BSCI and SEDEX (SMETA) standards, NAITRON serves as a trusted OEM and ODM partner for prominent home furnishing and sanitary ware brands. Its products are exported to more than 20 countries, including Germany, the United Kingdom, Spain, the Netherlands, the United States, and Japan, with markets spanning Europe, North America, Southeast Asia, Australia, and the Middle East.

With its innovative material technology, patented TMT molding technology, digitally controlled production systems, and large-scale manufacturing facilities, NAITRON supports flexible production and large-scale delivery for international markets.
