Common Dome needle to mold common common dome needle, thimble without mold factory production directly to the mold parts manufacturers or shops to buy. In the selection of the thimble, thimble standard should be adopted. Non-standard thimble generally custom-made, and the price is several times the standard thimble. Ordinary dome top when the thimble is curved needle to prevent rotation of the thimble, thimble need to set a fixed end positioning structure. Two common thimble to locate structures. Do thimble fixed end positioning structure when the top is curved thimble, in addition to the fixed end do need anti-rotation structure, the need at the top of thimble processing a plurality of grooves. The purpose is to prevent sliding products in the top of the process. Thimble with the length of the part I need to be equal, non-mating portion 0.5 avoid the need for space. For small thimble, such as diameter 2.2,2,1, with part of the length required to be equal. Bakelite, also known as Bakelite, high mechanical properties, rigidity, cold flow is small, the heat resistance at 100. . Above, the friction coefficient of 0.01-0.03 under water lubrication, ability to good electrical properties and resistance to acid erosion, forming simple tpu tpv, inexpensive, but more brittle nature, limited color, Poor resistance to rotation, arc resistance small, impatient strong oxidizing acid corrosion. Commonly used in plate, tube and bar in. It can be used as agricultural submersible pump seals, bearings, bearings, pulleys, gears, brakes and clutch means. - Polystyrene has a very good geometric stability, thermal stability, optical transmittance, electrical insulating properties and a very slight hygroscopic tendency. -5 Can be divided into (modified polystyrene) and @ 5 (high impact polystyrene) two. - Transparency of 8870-9270, suitable for light transmission parts, its dyeing strong, non-toxic and tasteless tpv 6145, has high impact resistance and acid and alkali resistance, and easy to shape. Suitable for decoration, such as lighting signs, shade, transparent toy, a transparent solution and the insulating film. If stored properly, usually it does not need to be dried. If you need to dry tpv, it recommended drying conditions for 80.0,2? 3 hours. Further, the shrinkage rate of a melting temperature of 1801-280.0, a mold temperature of 40-50. - Tpv 6145, Gary trade (certification), provided by the Shenzhen Longgang tpv Gary Trading Limited.
