The quality of a rubber compound strongly affects the performance of the final product. At KRAIBURG Rubber Suzhou, we control every key step. This includes raw material selection, recipe development, mixing, testing, and delivery.
Our integrated management system is certified to the following standards:
KRAIBURG Rubber Suzhou has also achieved 4A Green Factory status. This reflects our focus on efficient, low-carbon, clean, and sustainable production.
Our quality system includes experienced teams, selected raw materials, strong mistake-proofing systems, and controlled production processes. We also ensure full traceability from raw materials to finished rubber compounds. We monitor workflow, process data, and product performance closely. Our automated production processes record key information from each step. This includes raw material testing data, mixing parameters, processing data, and final product test results. We test each batch according to customer specifications. Standard release tests include rheology, viscosity, hardness, density, and tensile strength. Through certified management systems and continuous improvement, we help customers receive stable rubber compounds, reliable service, and responsible material solutions.
About 10% of our employees work in research and development, process engineering, and quality assurance. Their expertise helps us develop reliable rubber compounds for demanding applications.
Our database includes thousands of formulations and test results. This knowledge helps our chemists select the right compound faster and more accurately.
A good rubber compound depends on more than the recipe. It also requires high-quality raw materials, advanced mixing equipment, strict process control, and accurate laboratory testing.
We use raw materials from selected suppliers. We also check incoming materials to ensure stable quality. Our tests include standard methods such as viscosity, melting point, and moisture checks. We also use modern physical and chemical methods, including TGA testing.
KRAIBURG Rubber Suzhou installed a clean room in its production facility. The clean room follows ISO 14644-1 Class 6, which is equivalent to US FED STD 209E Class 1000.
The clean room includes two mixing lines with open mills, batch-off equipment, and one open mill compounding line. These facilities allow us to produce rubber compounds under very clean conditions.
Clean room compounds are suitable for applications such as:
We inspect every compound produced in the clean room. Our laboratory also provides an inspection certificate for each batch.
Our traceability system records each production step. This allows us to trace the final compound back to the lot number of each raw material batch.
Gezolan (KRAIBURG), LP 位于美国佐治亚州 Buford / Hamilton Mill 的工厂正式开业。这是 Gezolan AG 在瑞士以外的首个生产基地，主要面向美国市场进行生产。
KRAIBURG TPE Technology (M) SDN. BHD. 位于马来西亚吉隆坡 Seri Kembangan 的生产基地开始投产。从 2007 年 6 月 6 日奠基到正式投产，仅用了半年时间。
KRAIBURG Walzenfertigung GmbH 在奥地利 Geretsberg 成立。随着辊筒业务部门从 Gummiwerk KRAIBURG GmbH & Co. KG 中拆分出来，KRAIBURG Walzenfertigung 于 2002 年 1 月 1 日成为一家独立公司。
KRAIBURG TPE GmbH & Co. KG 在 Waldkraiburg 成立，并拥有自己的生产工厂。从 2001 年 3 月 1 日奠基，到 2001 年 10 月 20 日正式开业，热塑性弹性体混炼胶生产厂房在不到一年的时间内建成。
Gummiwerk KRAIBURG RELASTEC GmbH 在 Salzwedel 成立。RELASTEC 成立于 1991 年 4 月，并于 1993 年 7 月 2 日启用了一座新的生产厂房，生产面积约 1,200 平方米，用于制造绝缘材料。
RELASTEC 是 KRAIBURG 在德国东部拓展业务的第一家公司。
Gezolan AG 在瑞士 Dagmersellen 成立。仅三年后，KRAIBURG 决定将这一业务理念拓展至瑞士，即利用再生橡胶制造新产品。GEZOLAN AG 随后成立，总部位于瑞士卢塞恩州的 Dagmersellen。
在 KRAIBURG，将废旧橡胶加工成新产品的初步尝试取得了成功。由于 KRAIBURG 看到了该领域巨大的市场潜力，因此收购了位于 Tittmoning 的一家公司，后来发展成为 Gummiwerk KRAIBURG ELASTIK GmbH。
Gummiwerk KRAIBURG Austria Ges.m.b.H. & Co. 在奥地利 Geretsberg 开始投产。由于当地地理位置接近且市场机会良好，在奥地利建立独立生产基地成为理想选择，因为当时高额关税壁垒使向奥地利出口变得不可行。
1964 年 8 月，位于奥地利 Geretsberg、距离 Waldkraiburg 57 公里的 “Sängergut” 庄园通过拍卖购得，并被改建为橡胶工厂，即 Gummiwerk KRAIBURG 的奥地利工厂。
Gummiwerk KRAIBURG 的历史始于 1947 年 10 月 22 日。那一年，Friedrich Schmidt senior 在 Kraiburg–Hart 开始生产橡胶混炼胶。当时资源十分有限，经营条件也非常艰难。
尽管 Gummiwerk KRAIBURG 的起步相当朴素，但这为 KRAIBURG 集团未来的成功奠定了坚实基础。凭借创始人之子 Peter 和 Fritz A. Schmidt 坚持不懈的努力与投入，公司销售额和产量逐年增长。
Opening of the Gezolan (KRAIBURG), LP plant in Hamilton Mill, Buford/GA. The first Gezolan AG production site outside Switzerland manufactures primarily for the American market.
EPDM Granules / Floor Coverings
Establishment of today’s KRAIBURG PuraSys GmbH & Co. KG with its own production plant in Diepholz.
Polyurethane
Start of production at KRAIBURG TPE Technology (M) SDN. BHD. at Seri Kembangan-Kuala Lumpur, Malaysia. Production began within half a year after the laying of the foundation stone on June 6, 2007.
Thermoplastic Elastomers
Establishment of KRAIBURG Rubber (Suzhou) Co. Ltd. with production plant in Suzhou/China.
Rubber Compounds
Start of production at KRAIBURG TPE Corp. at the Duluth, Georgia, USA site.
Thermoplastic Elastomers
Establishment of KRAIBURG Walzenfertigung GmbH in Geretsberg, Austria. With the split-off of the roll division from Gummiwerk KRAIBURG GmbH & Co. KG, KRAIBURG Walzenfertigung became a separate company on January 1, 2002.
Rollers and Roll Coverings
Establishment of KRAIBURG TPE GmbH & Co. KG with its own production plant in Waldkraiburg. From the ground-breaking ceremony on March 1, 2001 to the official opening on October 20, 2001, it took less than one year to complete the production building for Thermoplastic Elastomer compounds.
Thermoplastic Elastomers
Establishment of Gummiwerk KRAIBURG RELASTEC GmbH in Salzwedel. RELASTEC, established in April 1991, opened a new production hall on July 2, 1993 with a production area of about 1200 m² for the manufacture of insulating materials. RELASTEC was the first company in which KRAIBURG expanded into Eastern Germany.
Insulation systems
Establishment of Gezolan AG in Dagmersellen/Switzerland. Only three years later it was decided to expand operations with this business idea in Switzerland, where recycled rubber was used to manufacture new products. GEZOLAN AG was established with headquarters in Dagmersellen, in the Swiss canton Lucerne.
EPDM Granules / Floor Coverings
At KRAIBURG, the first steps toward processing old rubber into new products were successful. Since KRAIBURG saw great market potential in this segment, a company in Tittmoning was acquired, which became Gummiwerk KRAIBURG ELASTIK GmbH.
Elastik – Stable Flooring; Strail – Products for Rail Systems
Production begins at Gummiwerk KRAIBURG Austria Ges.m.b.H. & Co. in Geretsberg, Austria. The geographical proximity and the good market opportunities there were ideal for establishing a separate production site in Austria, since the “high customs wall” made exports to Austria unfeasible. In August 1964 the “Sängergut” estate in Geretsberg, Austria, 57 km from Waldkraiburg, was bought at auction and converted into a rubber factory: Gummiwerk KRAIBURG’s Austria.
Tire Retreading
The history of Gummiwerk KRAIBURG began on October 22, 1947. In that year, Friedrich Schmidt senior began producing rubber compounds in Kraiburg – Hart, using rather limited resources and operating under very difficult conditions. While the beginnings of Gummiwerk KRAIBURG are rather humble, a solid foundation was laid for the future success of the KRAIBURG Group. Thanks to the tireless work and commitment of the founder’s sons Peter and Fritz A. Schmidt, sales and production increased year on year.
