Ingenuity is evident in every detail. Pure Diamond protects the “high-temperature defense line” of industrial profiles with its quality

In Foshan, the world-renowned “Aluminum Capital of China,” modern aluminum extrusion production lines transform raw aluminum ingots into components for building curtain walls, elevated railway lines, and precision equipment. The smoothness and flatness of the aluminum surface directly determine the product’s ultimate value and market competitiveness.

In this meticulous quality battle, a “behind-the-scenes” material—high-temperature-resistant industrial felt—has a profound impact on aluminum extrusion production yield and cost control. It plays a crucial role in ensuring a “zero-defect” aluminum surface during the extrusion process.

Pure Diamond New Materials (Foshan) Co., Ltd. (hereinafter referred to as “Pure Diamond“) was born out of this mission. Since 2016, Pure Diamond has been rooted in Dali, Foshan. Driven by independent research and development and grounded in superior quality, Pure Diamond has established a “high-temperature defense” in the industrial consumables market, safeguarding the impeccable surface finish of aluminum profiles in China.

Over the past decade, Pure Diamond has adhered to a high-quality foundation, forging a new path in the development of industrial profile felt and becoming a shining star in Foshan’s intelligent manufacturing landscape. In this issue, explore the secrets behind Pure Diamond’s superior quality.

From strategic transformation to technological breakthrough, laying the foundation for “high temperature defense”

“Born for industrial aluminum profiles!” Pure Diamond’s General Manager, Zhan Yuncong, explained in an interview the company’s shift in focus from traditional profiles to industrial profiles.

Behind this transformation lies Pure Diamond’s deep consideration of the prospects of the industrial consumables industry. Perceiving the shrinking market for traditional profiles and the improving market for industrial profiles, Pure Diamond decisively shifted its product positioning, focusing on the industrial profile market and overcoming technical challenges to forge higher-quality industrial felt to meet the production requirements of industrial profiles.

From material upgrades, process refinement to performance leaps, Pure  Diamond has introduced several advanced precision equipment, established a professional product and process design team, strictly controlled the source of raw material screening, carried out in-depth optimization and material innovation for the pain points of aluminum profile production, and output high-quality aluminum profile felts that exceed the quality of its peers.

Its core product, the high-temperature and wear-resistant industrial felt roller, can directly face the harsh scene test of the extrusion front end, and can withstand the ultra-high temperature environment of 650°C, far exceeding the performance of its peers at 600°C for only 10 seconds. Through many technological innovations.

Pure Diamond has also successfully developed a customizable roller with an inner diameter of 18mm.

Currently, only a few companies in the industry can master and realize it, effectively ensuring the smooth operation of the one-out-two, one-out-four, and other one-out-multiple processes of quenching and extrusion of mid-to-high-end industrial materials such as new energy vehicles, 3C electronics, and solar frames.

This unique persistence has also enabled Pure Diamond to quickly grow from a technological breakthrough to a leading company in the industry, and to stick to the ideal foundation of the “high-temperature defense line” of aluminum profiles.

Breaking through the “price encirclement” of industrial felt and exploring the development prospects of enterprises with quality

Aluminum profile production is a “long march to quality” that traverses high temperatures and high speeds.

As price wars rage within the industry, with many companies focusing on boosting sales through low prices, Pure Diamond remains committed to improving product quality.

We are committed to building a comprehensive product portfolio that covers key aspects, continuously upgrading our high-quality fiber manufacturing process, and providing a tailored “protective armor” for aluminum profile production.

Pure Diamond utilizes carefully selected PBO high-temperature-resistant specialty fiber  materials imported from Japan. This material, known as the “golden fiber,” undergoes precise combing and meticulous forging through multiple composite processes, then undergoes ultra-high temperature pressing and shaping to ensure the fibers are tightly locked and heat-resistant, allowing the aluminum to maintain excellent condition in extremely high-temperature environments.

While the aluminum ingot is pushed into the mold and subjected to high temperatures, the PBO felt pads  and PBO gloves form the first line of defense. At temperatures exceeding 600°C, they effectively block heat transfer for 25 seconds, protecting the safety of equipment and operators, while also preventing defects in the aluminum profile caused by heat damage during the initial forming stage.

At the same time, Pure Diamond produces products adapted to the production environments of 500°C, 280°C, and 180°C, based on the production requirements of different aluminum profiles, ensuring the stability of product quality in all scenarios of aluminum profile production.

Relying on its high-quality product quality and industry reputation, Pure  Diamond has established long-term and stable cooperative relations with many aluminum profile companies, such as Safe, Yilike, Yuehang Technology, Tongrun Intelligent, Zhongyifeng Luopujing, CITIC Bohai Aluminum, Tuotian Aluminum, Conglin Aluminum, and Nanshan Aluminum, shaping brand effect to open up the domestic market.

“Tough as a diamond, fearless of heat!” This powerful slogan perfectly reflects the Pure Diamond’s ability to withstand the harsh, high-temperature conditions of aluminum production.

Combining three core attributes—high-temperature resistance, wear resistance, and thermal insulation—Pure Diamond covers the entire aluminum extrusion production process, from heating the aluminum ingot and isolating the ultra-high-temperature areas at the front end of the die extrusion process to surface protection and temperature maintenance during post-extrusion transfer. This product provides reliable protection for every step of the process.
