Note that the top of the push plate is not suitable for all types of mold in the mold of the need for the push plate to the top of the structural design of the push plate. Basics mold structure fixed using spacers push block and push plate to push the top of the top of the board design to apply to the barrel, thin-walled, transparent, does not allow thimble traces of plastic products. Push the top of the board has the advantage of a uniform force, products not easily deformed, the disadvantage is pushing plate processing difficulties, does not apply to sub-surface complex parts. Push block the top of the push block at the top of the transparent material commonly used products pvc wire tube, the product surface and not allowed to have traces of the use of the push plate thimble way ejection. Figure 2-57 shows the block to push the top of the structure diagram, can be learned from the figure, the push block connected together by a screw thimble, push the block to be done outside of the slope. Very easy to push the block with high hardness and a smaller surface roughness, and to ensure there is enough strength to push the block, while ensuring low friction during movement of eight 6: push the block in the top of the design should pay attention to the following points when pvc plastic bags to absorb water, so the need to be dried before processing. If the material is packed in waterproof material supply, the container should be kept closed. If the relative humidity is greater than 0.2 ^, recommendations dried in hot air 801 over 16 hours. If the material has been exposed to more than eight hours in the air, it recommended vacuum drying 1051,8 hours. Typically, the melting temperature of a mold temperature of 230-2801 801-90. Six 6 has good mechanical strength, stiffness and abrasion resistance pvc flooring manufacturer, is widely used in structural components and bearings. Eight in 66 have a higher melting point polyamide material, so? Eight 66 at a higher temperature to maintain a strong strength and stiffness. Six 66 still has moisture in the molding, the extent depending on the material composition, thickness, and environmental conditions. In the design of products to consider the impact of moisture on the geometric stability. In order to improve? Mechanical properties of eight 66, usually by adding a variety of modifiers, glass is the most common additives, sometimes in order to improve impact resistance has also joined synthetic rubber. Eight 66 less viscous, so liquidity is very good. ? Shrinkage eight in 19 ^ 66? Between 270 glass fiber additives can reduce shrinkage to 0270- generations 0. If the processing of the material is sealed pvc, there is no need to dry. If the storage container is opened, it is recommended dried at 85.0 hot air. If the relative humidity is greater than 0.2, it also needs to 1051,12 hours of vacuum drying. The melt temperature was 260 compared with 66 opening six six six, eight 66 more widely used in automotive, housing and other needs instruments impact resistance and high strength requirements. pvc flooring manufacturers, Gary trade (certification), Luohu District, Shenzhen, pvc provided by Gary Trading Limited.
