Products Range

SynthoTec is ready to deliver precision moldings for almost all types of bearings according to your specification. Our standard range of diameters from 20 mm to 250 mm. However we can adapt to the requirements outside of this range. Other products are not limited to a size range; restriction is only the final molding. We use the technology to enable the production of moldings weighing from a few grams to over 500 grams.

Generally, we design and produce the multiple forms - bearing cages up to 16 cavities, and other parts at a higher cavitation. This allowed us to offer attractive terms of cost for customers. Each of our machine contains a form of robotic manipulation, which is designed to measure the customers' requirements for packing method. The very form of the final packaging and labeling is fully in the hands of the customer. SynthoTec can adapt to any requirement for the method of packaging and delivery of products. The selection of product types is shown below.

Technical sources

SynthoTec has its own design department, which is an effective tool in improving customer service. Experience in the production of plastic injection molding parts can thus be directly applied on a daily basis to design new projects to optimize production efficiency. Efficient use of standard and purchased parts finest tool steel for functional forms of guarantee fast and easy maintenance over life forms. SynthoTec has its own qualified engineers who process documentation from the first prototype through distortion, correction and optimization of forms in CAD programs in all common formats (* .dxf, * .dwg, * .igs * .stp, * .step). For the design itself to use software Creo Parametric (recently known as ProEngineer). As standard procedure ensures product visualisation and rapid prototyping work. According to the complexity of the molding also we provide Mold Flow analysis products. For making molds normally used primarily by German and Austrian suppliers and steel, most often from Swedish suppliers. The actual production forms a skilled base of selected European toolmakers with years of experience with these kinds of products

Production process

The production process is ensured by the latest injection technology. We only use modern injection molding machines nanipulačnými by modern technologies. Our line consists of the latest models of presses (Engel, Battenfeld, Demag ...) by robotic handling production facilities (ABB, FANUC ...). The line is always composed for the customer project which ensures optimal use of the kit according to customer specifications.
Normally we handle all types of engineering plastics PA6 starting over PA66, PPA, PA46, PA12 to the highest grade PEEK board. Equally, however, we can handle all of the class of engineering plastics.

Top quality

Our integrated management system is the backbone of quality management and environmental management. The company is certified to ISO 9001: 2008 and ISO 14001: 2004. Production procedures and controls for individual components are in line with customer requirements and meet the strict requirements of the automotive industry. To measure and control the quality of products we use modern optical and tactile measuring equipment Batya, ZEISS, Mettler-Toledo, Mahr, grids. The staff of quality are regularly trained on the latest measurement procedures and the use of modern measuring equipment. The new products are manufactured according to the agreed plan and APQP approved for production after approval of the document PPAP
