Welcome to Sonderhoff (Suzhou) Sealing Systems

Sonderhoff started in China with a representative office in 2004. The business of Sonderhoff developed very well and the customers required having Sonderhoff excellent support also directly in China.

Therefore Sonderhoff founded 2009 in Suzhou the new entity Sonderhoff (Suzhou) Sealing Systems Co., Ltd. being responsible for the exclusive sales and distribution of all products of Sonderhoff in China and Taiwan.

In the following year Sonderhoff also started to offer the contract gasketing service to customers in the SIP (Singapore Industrial Park) and Jiangsu area with three dispensing machines. The contract manufacturing service for foam gasket, gluing and potting applications is also available for customers who have their own dispensing machines.

Sonderhoff Suzhou offers individual sampling of prototypes, as well as pilot application processes from small batches up to serial production.

In order to become more independent from exchange rates and import duties Sonderhoff decides to move into a new greater plant in SIP to be able to start the local polyurethane material production.

Sonderhoff Suzhou introduces SAP as the company ERP system and qualified the processes according to ISO9001 which was certified from TÜV Rheinland beginning of 2017.

The new material production from Sonderhoff in China and the new machines for expanding the contract manufacturing of Chinese customers’ parts is an investment in the future for the company’s further growth.
