The glass mould brick produced by Zhengzhou Sunrise Refractory Co., Ltd. is a refractory unit designed for direct contact with molten glass during container and automotive glass forming. It is made from high‑alumina refractory fireclay, a material that offers excellent thermal stability and resistance to chemical attack at temperatures up to 1050°C. The brick’s dense micro‑grade structure is pressed and sintered to achieve a uniform composition that limits permanent linear change during reheating cycles. This construction enables the brick to maintain its shape and dimensional accuracy throughout repeated heat cycles.
Industry standards for refractory bricks used in glass moulds call for a low permanent linear change, typically less than 0.1 % after reheating, and a high compressive strength above 30 MPa. The bricks from Zhengzhou Sunrise exhibit these characteristics, with a reported negligible linear change when fired at 1050°C. Their thermal shock resistance is such that no cracking occurs after prolonged service, a typical requirement for continuous glass‑forming lines. The bricks are also engineered for easy machining, allowing customers to trim them to exact dimensions and avoid waste.
These bricks are widely used by manufacturers of rear‑view mirrors, automotive glazing, thermal‑bending glass and artistic glass applications where precise temperature control is critical. Zhengzhou Sunrise offers flexible order quantities and ships the bricks in steel drums with protective liners to guard against damage. While the supplier mentions a long‑standing production line since 2003, buyers should verify the current production capacity and any applicable certifications before finalising a contract.

Zhengzhou Sunrise Refractory Co., Ltd. is situated at No.36 Fengchan Street, Jinshui District, Zhengzhou, Henan, China. The company holds a harbour‑level trust tier on the platform, but its response rate and average response time are not recorded in the source data. Its location in Henan places it near several major refractory material clusters, facilitating access to raw fireclay and high‑alumina powders.
The profile states that the firm has operated a dedicated mould‑brick production line since 2003 and focuses on units for automotive glass and container glass applications. No additional corporate details such as employee count, revenue or client list are provided, so interested importers should request any relevant quality certificates, test reports or audit findings directly from Zhengzhou Sunrise.
Glass mould bricks are specialized refractory units designed for use in glass container moulding and automotive glass manufacturing. These high-temperature resistant bricks provide the thermal stability required for molten glass contact in rearview mirror production and similar precision glass forming applications. Sourced from fireclay or high-alumina refractory compositions, they offer superior thermal shock resistance and dimensional accuracy under continuous heat cycling. Widely sourced by glass manufacturers and automotive parts suppliers from refractory material exporters in China, India, and Eastern Europe.

Before confirming a purchase, importers should request a material composition analysis for the high‑alumina fireclay, as well as thermal conductivity and linear‑change test reports. Obtaining the brick’s dimensional drawing and tolerance sheet will help verify that the product meets the required specifications for your glass‑forming line. These documents provide a clear basis for quality assurance and reduce the risk of receiving non‑conforming refractory units.
Logistics should be clarified by agreeing on Incoterms such as CIF or FOB, specifying the loading port in China and the destination port, and confirming the expected lead time for custom‑size production. Payment terms are usually arranged via T/T against a pro‑forma invoice, but the exact schedule must be documented in the contract. Verify that the steel drums include moisture‑resistant liners, especially if the bricks will be stored for an extended period before installation.
Quality control typically involves a third‑party inspection of compressive strength, dimensional accuracy and thermal‑shock performance before shipment. Importers may ask for an inspection certificate or a copy of any ISO or other relevant certifications to substantiate the supplier’s quality claims. Ensure that the shipment is accompanied by a packing list, certificate of origin and all test reports so customs clearance proceeds without delay.
