多層拉伸套膜吹膜機
產品分類 : 吹膜押出機
People replace stretch wrap film with stretch hood film. The stretch hood film has excellent holding force and extraordinary elasticity, so that it could cover the cargo tightly and prevent the stacked sacks from collapsing. It improves the security in logistic transportation greatly. Furthermore, it has high puncture resistance to protect the goods and provides good transparency that assist people to distinguish the content of cargo and to scan the labels. Specification Layers: 3 / 5 layer Distribution ratio: 1:2:1, 1:3:1, 1:1:2:1:1, 1:2:4:2:1 and so on. Film width: 1500 ~ 1850 mm Output: 280 ~ 450 kg/hr
EMI SHIELDING
產品分類 : 工業與精密部件&護具
Protect parts from electromagnetic interference. It is used to protect electrical signals from the outside world. Currently, construction methods for anti-EMI are electric plating, sputtering, spraying, electric paint, or the direct use of the shielding effect of metal materials, such as the use of stainless steel, aluminum, iron or aluminum-magnesium alloy, and other materials. The metal piece of masking is low cost and meets current environmental regulations. But the processing and assembly are complex and miscellaneous and are poor stability. Water electroplating, electric plating, conductive paint, and other environmental laws and regulations conflict or doubt, the establishment of the new plating plant is not easy in the future and will gradually be phased out and replaced. So far, workers using a vacuum sputtering process and the magnesium alloy should be the main way to effectively combat EMI.

(1) Crowned tooth allowed larger tolerance in shafts and higher loads. (2) Special hardening treatment W/high strength and anti-abrasiveness. (3) Closed type coupling--easy lubricate & anti dust as well as no leakage. (4) The type of TIEN YI GEAR SHAFTS COUPLINGS had been successful the first processing, it must be done the second procedure heat treating again according to material. And it were given them more rigidly precise, increasing stronger tenacity. At last removing gravitation by striking-ball bearing when those steps all finished.

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.
