Wall thickness, rigidity difference thimble arranged in strength, rigidity of the top portion of the thimble is to be set when positioning structure curved surface features to prevent thimble rotation. Thimble top surface should be flat, to avoid the ramp portion is arranged thimble, shown in Figure 2-41. Thimble should try to avoid laying on an incline, (fighting) for Transparent plastic products need attention thimble marks will affect the appearance of the product, thimble arrangement does not affect the need; ^ BU concept of the site, as shown in Figure 2-42. Thimble can be arranged at the outer wall thicker, this method is suitable for use in a small mold. When the mold is large, if smaller diameter thimble, at the top of the process is easily deformed, then you can use a thimble arranged. Transparent products thimble arrangement Method 2 (c) of the thimble and the cooling water should be kept a reasonable distance, to avoid a collision between the two. When there is enough space layout thimble thimble need to use a larger diameter to ensure adequate strength thimble. Preferred standard sizes of thimble pe, as far as possible no or little use non-standard thimble and thimble specifications should be minimal. Dome of the needle is the most common thimble type is the most frequently used thimble. Dome of the Dome of the needle into ordinary needle and have entrusted the two domes. Polyethylene Polyethylene is a plastic industry in the highest yield, lightest plastic. Polyethylene translucent white shape, light crystalline plastics, has excellent low temperature performance (the lowest temperature up - electrical insulation, good chemical stability, resistance to most acid-base erosion appropriateness of using injection , blow molding and extrusion and other processing methods, such as living in the cable sheath, buckets, pots and tape. shrinkage rate, polyvinyl chloride, is one of the widely used plastic material, which is a non-crystalline materials. material in actual use, often by adding stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives. material is not easily flammable, high strength, corrosion resistance, resistance to climate variability and excellent geometric stability sex For oxidants, reducing agents and strong acids have a strong resistance. The flow characteristics of poor, mold corrosion. There are soft and hard points, the appropriate range is different, usually used in blown film, calendered sheet and extrusion cable sheathing, usually used in extrusion rod, sheet, pipe, etc. The products are commonly used in life wire trunking and pipes. Rigid shrinkage rate, soft shrinkage rate, usually do not require drying the melting temperature of 185.0:? 205.0, a mold temperature of 20.0 50 has poly methyl acrylic methylphenidate, commonly known as acrylic or plexiglass eight, has excellent optical properties and resistance to climate change characteristics pe?. Shoes, penetrating up to 9270, but not enough surface hardness lol pe, easy to scratch. and? from \ 1 six hygroscopic, and therefore need to be dried before processing pe wax, recommended drying conditions for 901,2-4 months hours shrinkage rate viscosity, slightly poor fluidity, the material must pass through a high-temperature, high-pressure injection injection. injected wide temperature range, a melting temperature of 2401-2701. Some commonly used in the production of transparent structure, with a lens meter optical components, optical disks and other pe bags |.
