The DTK factory is located in Qingdao, China, and it is the core production base for its high-quality sealing solutions.
In terms of hardware, the factory is equipped with precision vulcanizing machines, automated production lines, high-precision CNC mold equipment, and a research and development laboratory, which enables the mass production of various sealing components. In terms of management, following the ISO9001:2015 standard, the factory uses the MES system for production monitoring and the quality assurance department conducts full-process inspections.
DTK technical dept. constantly keep in touch with our customers’ technical dept. and take charge of all the steps that have to be taken before series production due to our 20-year experience engineers, including: design drawing, compound development, samples making and pre-series production. And also our engineers cooperate with our customers to develop the best solution and supervise every modification during the life of item.
DTK production department includes two parts: vulcanization dept. and finishing dept.DTK production department includes two parts: vulcanization dept. and finishing dept.
Vulcanization dept. has moulding machines to guarantee the production sealing parts :
- moulding machines for injection;
- compression moulding machines.
Finishing department is the next process after vulcanization, to post cure and deflash items. With our equipments and experiences, surface treatments can be taken to satisfy the request of customers.
DTK Q.A. is the core of our quality. With the goal of 0 defect, our quality engineers are delegated into different processes, such as incoming material warehouse, vulcanization, finishing, final inspection, and finished parts warehouse, to take charge of quality control.
The inspection of finished parts is a key-phase of every production process aimed at guaranteeing the requested quality level on each item. Selection, either manual or automatic, is performed internally on 100% of each production lot. In our automatic selection department there are 11 optic inspection machines able to check surface quality and dimensional parameters both of o-rings and of parts at drawing. Shall manual selection be necessary (for instance, in case of parts of large dimension), DTK can rely on highly-experienced employees.
DTK logistics department offer the best logistic solution to our customers including express, air freight, sea freight, air-sea freight and train ect. Our highly-experienced employees are able to ensure 0 delay in transportation.

As a professional sealing component manufacturer established in Qingdao, China in 2012, DTK, leveraging its over a decade of experience in technical rubber sealing component design and production, has established a complete chain customization system from "demand analysis - scheme design - sample development - batch production".
The company strictly adheres to the ISO9001:2015 international quality management system and integrates quality control throughout the entire production process: from the import screening of rubber raw materials (establishing long-term cooperation with globally renowned rubber raw material suppliers to ensure the stability of the base material)
DTK has always adhered to the core logic that "details determine the sealing effect": it develops specialized rubber compounds (such as food-grade, medical-grade, and high-temperature and high-pressure resistant special compounds) for different application scenarios. Through surface smoothing treatment and precise edge cutting processes, it enhances assembly efficiency and sealing reliability.
Relying on the geographical advantages of Qingdao as a port city and its well-developed logistics network, DTK can achieve efficient import of raw materials and rapid export of finished products. Combined with a mature supply chain management system, it can effectively control production and transportation costs, providing global customers with cost-effective sealing solutions.
