Release time：2025-06-16

Looking to assess a glass powder factory’s strength? This guide delves into R&D soft power (team, patents) and hard power (equipment, mass production) to help you identify reliable sealing glass powder suppliers.

Introduction

In the industrial glass powder sector, especially for materials used in sealing, packaging, and special applications, a manufacturer’s R&D capability directly determines product performance and technological barriers. For foreign trade enterprises seeking to go global, choosing a supplier with robust R&D capabilities is crucial to ensuring product competitiveness in the international market. This article analyzes how to evaluate the true strength of a glass powder manufacturer through technical teams,patent portfolios, production equipment, and mass production capabilities, using Sinopride (www.spcera.net) as a case study.

• Dr. Shen Liang:

Executive Deputy General Manager, Ph.D. in Materials and Chemistry from Sun Yat-sen University. Specializes in metal-sealing glass and sodium-ion battery sealing materials, responsible for developing special glass materials like ultra-low-temperature glass for stainless steel sealing and oxygen sensor sealing materials.

The Ganzhou production base is equipped with 11 R&D personnel (including 2 doctors and 2 masters), whose professional backgrounds cover material physics, ceramic technology, electrochemistry, etc., forming a full-chain technical capability from formula design to application verification.

2. Patents and Intellectual Property: Quantitative Proof of Technological Leadership

• Patent Portfolio: 128 invention patents applied (42 authorized), 8 PCT international patents, covering core technologies like low-temperature sealing glass (400-500℃) and SH604 glass for lithium thionyl chloride battery caps. The bismuth-based low-temperature glass realizes substitution of lead-containing materials.

• Academic Achievements: Dr. Miao has published 101 SCI papers, Dr. Shen over 10 SCI papers and patents. Research results support major projects like "R&D of Special Sealing Glass and Its Application in Power Batteries".

• Certifications: National High-Tech Enterprise, Shenzhen/Ganzhou "Specialized and New" SMEs, certified by ISO9001, ISO14001, IATF16949, and military GJB9001C, ensuring standardized R&D processes.

II. R&D Hard Power: Equipment Capability and Mass Production Scale

1. Full-Chain Production Equipment: From Material R&D to Finished Product Manufacturing

Sinopride has built a complete production line covering "melting-ball milling-granulation-molding-sintering", with key equipment including:

• Melting & Grinding: 15 crucible melting furnaces + 1 continuous melting furnace (daily capacity 1,700-2,000kg), 8 horizontal ball mills (grinding powder to below 10μm, daily processing 1,000-1,500kg).

• Granulation & Molding: 2 production granulation towers + 1 experimental tower (1,500kg daily granulated powder), 33 molding devices including 9-punch rotary presses and 14-punch servo presses, monthly production of 20 million glass blanks.

• Testing Instruments: 20+ types of testing equipment such as laser particle size analyzers, helium leak detectors, electron microscopes, and universal testing machines, enabling precise control of 10+ core indicators like thermal expansion coefficient and airtightness.

2. Large-Scale Production Capacity: Meeting Global Order Demands

• Capacity Matrix: 3 sealing glass granulated powder production lines (monthly output 100 tons), 7 metal-glass sealing lines, monthly glass blank capacity exceeding 100 million pieces, suitable for large-scale applications like automotive sensors and lithium battery caps.

• Customized Production: Supports customization of parameters like thermal expansion coefficient (5.0-11.0×10⁻⁶/℃) and sintering temperature (400-980℃). For example, SK016 Kovar-sealing glass perfectly matches the thermal expansion coefficient of 4J29 metal.

• Process Verification: Oxygen sensor sealing powder rings have passed long-term verification by OEMs like Bosch and Continental. Lithium thionyl chloride battery caps have a leakage rate <1×10⁻⁹ Pa·m³/s and pull-out force >2,000N, meeting military-grade reliability requirements.
