Manufacturing equipment and testing instruments there are new developments

Seals production equipment and detection technology is moving towards automation, low cost, high reliability direction.
In the rubber mixing equipment, with automatic batching and mixing process of automatic control mixer system, effectively to achieve energy efficiency, reduce environmental pollution, while manufacturing high quality rubber compound material. To improve the effectiveness and efficiency of mixing, research focused on the manufacturer mixer rotor shape. Kobe Steel Mill and Farley children developed 4WH rotor respectively and ST rotor mixer, Japan's Mitsubishi Heavy Industries developed GK-E rotor focused productivity.
Molding process, the foreign widely used and efficient, advanced and high-quality rubber injection molding processing technology. Production of small products, reciprocating screw injection machine, large size products with a screw plunger-type injection machine, are effective to improve the appearance of quality and performance seals, save raw materials. Paker produced O-ring, using the injection molding machine to make a small burr products, frozen with liquid nitrogen, trimming, trimming plastic pellets and water stone washed three processes, product appearance reached a very high level.
Vulcanization process equipment, at present, many domestic manufacturers equipped with a vacuum barrier seals tablet and injection machine, vulcanizing machine is also for ordinary circulating oil heating transformation, in order to ensure process stability.
While manufacturers also attach importance to design software secondary development, with good mold cavity materials processing flow analysis, manufacturing aspects of CNC equipment has been widely used precision molds, and the apparent quality have reached a very high level. Greatly promoted China's technological development rubber sealing industry.
Detection technology, the latest development is the use of an optical system, such as: Freudenbezy used by companies such KMK developed third generation of new optical system completely replaced the manual inspection, success will seal quality testing is fully integrated into the production process, which kinds of image processing systems to achieve a high detection speed and detection accuracy can detect the tiniest seal surface defects, such as cracks, bubbles, impurities and slip lines.
Domestic companies have introduced a seal measuring tension of the oil seal lip of the oil seal primarily on detection means for detecting pressure changes measured properties of the oil seal lip sealing gas detector (Italy), having a higher detection rate, per hour can be detected 1200-1800 a metal seals.
In the manufacturing process has been widely used CNC machine tools, professional mold manufacturing company has been basically achieved full CNC. Precision molds, and the apparent quality have reached a very high level. At present, the domestic rubber seals enterprises there are many companies equipped with CNC machining equipment, mold design and machining applications in CAD / CAM has accumulated a lot of experience.
