DTK’s main markets we serve are

• General Machine
• Automotive
• Heating system
• Household Appliances
• Food and beverage

Technical office provides our customer designing service with exchange information. We focus on customer’s request from samples out of pilot tool and pieces out of series production. Thanks to years design experience and advanced technology, we are capable of providing the best solution of new applications.

DTK offer range of tailor-made solutions for automotive industry, from the simplest to complex ones.

Our products can meet the requests of high performance such as resistance to oils, agents, temperature, electrical conduction etc. Our team work with yours to develop the best solution on not only design and production, but also package and logistics. All is only just for meet your request with our service.

DTK provides customized solution for general machine applications: high and low temperatures, high mechanical and chemical resistance, anti-tearing, ozone resistance, excellent compression set….

This kind of application requires the best sealing gasket in difficult working conditions (temperatures, pressure, chemical, UV, fire resistance etc). DTK supply our customers the best products, produced according to the most advanced technological parameters, meeting FDA, WRAS, RoHS, EN681 etc

Gaskets used within small and big electric appliances: conductive, bonded seals (metal-rubber, plastic-rubber), non-toxic, high-low temperatures, colored according to RAL or PANTONE etc.

DTK is dedicated in making life safer and more comfortable, offer the optimal sealing solution facing multiple requests/working conditions from “FOOD grade” to high temperature resistance, from high tensile strength to non-staining compound.

For applications in heating system DTK offer seals made of all kinds of materials with the corresponding customer approvals and standard, such as:

EN 14241-1, EN549, WRAS, FDA, W270 etc.

Innovative and optimal solution is made by a teamwork between our engineers and your team, which meet the special quality and geometry requirements.

Thanks to the demand of silicone items, DTK develops a team dedicated in design new compound and innovative products for market.

Silicone has a lot of good specification, like resistance to low and high temperature (-70°C--+250°C), chemical, water, ageing etc. DTK silicone products are widely used in the condition contacting with skin and food according to standards WRAS, FDA, DVGW-W270, NSF, ACS.

DTK production department includes tool production, rubber mix, vulcanization and finishing process.

We produce molds for sealing parts according to customer drawing with very complex geometries and tight tolerance (dimension and flash).

Rubber mixing ensure the quality of compound before vulcanization.

Vulcanization process has molding machines to guarantee the production of sealing parts :

- Injection molding machines,
- compression molding machines.

Finishing process 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 technical dept. constantly keeps in touch with our customers and takes charge of all the steps that have to be taken before series production due to our 20-year experience engineers, including: design 2D/3D drawing, tool design, compound development, samples making and pre-series production. And also our engineers develop the best solution with customers and supervise every modification during the life of item.

DTK has been focusing its efforts on research and development of innovative materials being able to ensure functioning in most critical and extreme working conditions. Our achievements are peroxide-cured compound with good ability of anti-stain and self-lubricated compounds, oil resistant and ozone-resistant, color compounds, food-level materials, etc.

Materials for the drinking-water play a key role in DTK and our sub-supplier, all of them are tested and approved by the leading certification authorities and according the most important regulations, such as FDA,WRAS,DVGW,DIN etc.

That is why DTK has become one of the leading suppliers of sealing parts within the field of drinking water and heating system applications.

The most common materials DTK is supplying are: NBR/FKM/EPDM/MVQ/NR/CR/HNBR etc
