JB-CD Latex Condom Dipping Machine
产品分类 : 橡胶浸渍机
Condom manufacturing machine process Collecting the raw materials Rubber latex is obtained from the milky fluid produced by various tropical plants. Latex is actually an emulsion or dispersion of tiny rubber particles in water, and ingredients added to the latex must be able to attach to the rubber particles during compounding. Compounding Next, chemical additives are mixed to form a paste. This paste is then blended with the liquid latex in a process called compounding. Storage The latex and chemical compound is then unloaded into drums for storage, where it remains for approximately seven days. During this period, vulcanization chemically strengthens the bonds of the rubber. The storage time also allows any air, which might have been trapped in the mixture during compounding, to escape. Dipping The compound is then added to the dipping or condom-forming machine. The dipping machine is a long, hooded machine approximately 100 feet (30.5 m) in length. Thick tempered glass rods move along a closed belt between two circular gears. The belt drags the rods, which are called mandrels, through a series of dips into the latex compound. The mandrels rotate to spread the latex evenly. Several coats are required to build the condom to its required thickness. Between each dip, the latex is hot air dried. After the final dipping and drying, the condoms automatically roll off the mandrels. A machine shapes and trims the ring of latex at the base of each condom. Tumbling Next, the condoms are put in a tumbling machine, where they are coated with talc or another similar powder to prevent the rubber from sticking to itself. Testing After a curing period of several days, the condoms are sampled by batch and tested for leaks and strength. The first such test is the inflation test, in which the condom is filled with air until it bursts. Condoms are required to stretch beyond 1.5 cubic feet, about the size of a watermelon, before bursting. This test is considered most important because the elasticity of the condom keeps it from tearing during inter-course. In the water-leakage test, the condom is filled with 10 ounces (300 ml) of water and inspected for pin-sized holes by rolling it along blotter paper. Condoms are also tested electronically. This involves mounting each condom on a charged stainless steel mandrel. The mandrel is passed over by a soft, conductive brush. If pin holes are present, a circuit will be established with the mandrel, and the machine will automatically reject the condom. Packaging Condoms that have successfully passed these tests are rolled by a machine. Rolling the condom makes it easier to package and use. Lubricant and spermicide may be applied by a metering pump just before the top wrap is added in the foiling process.

Utraflex / Utraflex-H-The UV-LED press
产品分类 : 柔版印刷机
The Ultraflex press is a UV-LED central impression press to provide high quality print with high opacity. At the same time Ultraflex press is an ecofriendly solution as UV-LED application does not emit VOCs. The Ultraflex-H is a hybrid press that integrates 3 technologies, the UV-LED ink application, solvent/water-based ink application and the central impression (CI). The Ultraflex-H enables you to take advantage of the UV-LED application but at the same time draw back to the solvent based or water-based print stations when needed If you are looking for a flexible, cost effective and production efficient press, the Ultraflex series is the press for you to customize.
WASTE TYRE RECYCLING
Reasonable budget and friendly operation Waste Tyre Recycling System with best quality from Taiwan Because of the many grades of the end product and the wide variety in the choice of machinery we are in a position to offer our services in the design, selection, supply, erection and commissioning of complete plants or single machines based on the specific regional and economic conditions. In order to reduce the wear and increase the life time of knives, ChangWoen has designed a three-stage processing technology (pre shredding, granulating, fine grinding) with much economical solution which ultimately produces vary high-quality materials for recycling. Against of shredding entire tyre with steel get rid of steel bead in the beginning of process and that leads to a economical way to I increase the life of knives by 30% more rather than without De-Beading Machine.
