Our programme consists of finished products and components that we produce with various technologies. Our services connected to blow moulding and blowing of plastic material are vast as we have in possession modern machines of different capacities.
SEP company offers counselling and development of complete products on your demand. We are connected to many suppliers enabling us fast and efficient production of tools for blowing, blow moulding and welding technology. CATING company, our external partner that cooperates with our excellent development department, enables custom constructing, preparation of 2D&3D documentation, production of test samples and serial production validation.
We cover different technologies of plastic processing such as blow moulding and blowing as well as bonding of products from different technologies with welding technology.
Throughout this process until the final product you will be accompanied by a professional personnel for managing such projects.
The technology of blowing plastic is in modern world probably one of the fastest growing technologies in plastic material processing industry as it offers optimal speed and satisfactory quality hollow products. There are currently no other plastic processing methods which could offer such wide array of products and economic advantage.
Thanks to our 20-year experience with this technology we can provide production of many different hollow products with volume from below 0.5L to 30L. The combination of our know-how and suppliers provides a proper processing of semi-products with various devices and robot technology. Furthermore, we also offer counselling in product construction or take over the complete product and tool development. With the year 2016 we now kave knowledge on suction blow molding technology, which in our technical part represents one machine with 7 ton of clamping force.
With blowing technology we can meet the highest quality demands in different industries such as automotive and appliance industries.
Blowing can be done with PE-HD and PP. However, we also have sufficient capacities and know-how to perform custom tests per customer needs. We have 9 blowing machines with closing force from 10 to 40 kN at our disposal.
Plastic welding is presented in standard ISO 472 as bonding of two softened materials. Normally the process is enabled by heat except in welding with solution. Welding of thermoplastics is usually done in three steps: surface preparation, heat implication and cooling. Depending on the different mechanical heat supply various ways of welding have been established, classified as internal and external methods.
At SEP company we offer traditional Hot-plate welding based on heating of both parts with hot elements with a temperature from 180 to 300 degrees Celsius. Elements are nickel-plated or silver-plated, for performance up to 260°C we coat them with PTFE. Most often both parts of intermediate heating elements are heated until the product starts to thicken at the weld. After that the element is pulled out and the halves or segments are quickly bonded together under the pressure between 0.1 and 2 N/mm2 which has to last until cooling.
Modern thermoplastic injection moulding machines within 35kN and 200kN power enable us a stable production process and hence a high quality of injection moulded products which are mainly exported for automotive industry.
Injection moulding is one of the most widespread methods of designing plastic material. The popularity of the technology results from the possibilities of its usage in serial production and in successful achievement of strict buyer tolerance. Based on our many years of experience we offer fast and efficient production of tools for your dream product while offering services and the development of the product itself.
The machines are equipped with integrated automated transport belts, gauges for automated counting and separators which enable short lead time from the order, production to shipping.
We process different materials with injection moulding:
We achieve higher added value of our blow moulded and injection moulded products by manually assembling them, using machines designed specifically for this purpose. We take care of everything so our customers don’t have to – we manufacture the product and all the necessary components, or order them from tried and tested, reliable suppliers. Finally, we assemble the finished product.
