Security: In the drawing process, the role of the die is drawn at the drawing force unit area on the wire cross-sectional drawing stress σ1. To make the metal mold plastic deformation in the hole, drawing stress σ1 must be greater than the deformation resistance σT mold hole in the metal deformation zone; and in order to prevent the wire out of the die hole and continue deformation attenuated or pull off thereby destabilizing drawing process, drawing stress σ1 must be less than the die hole after the wire is drawn yield limit σs, and therefore for achieving the drawing process is usually expressed as: σT <σ1 s="" the="" ratio="" of="" k="" with="" safety="" factor="" called="" drawing="" process="" a="" href="http://www.jawaysteel.com/ER70S-6-Weld-Wire-Suppliers.htm" data-mce-href="http://www.jawaysteel.com/ER70S-6-Weld-Wire-Suppliers.htm">ER70S-6 Weld Wire For Sale

Condition: subjected to cold-drawn wire produce significant deformation hardening, its yield limit σs value close to their ultimate strength σb, σb commonly used in the production of value instead of σs, thus achieving the drawing process conditions can also be expressed as σT < σ1 <σs; drawing="" process="" safety="" factor="" of="" k="" ratio="" b="" with="" 1="" also="" available="" representation="" a="" href="http://discountstainlesssteel.com/stainless-steel/7792.html" data-mce-href="http://discountstainlesssteel.com/stainless-steel/7792.html">Stainless Steel Pneumatic Cylinder Tube

Safety factor: the drawing process safety factor K value is generally 1.40 to 2.0, K <1.40 represents="" the="" drawing="" stress="" 1="" is="" too="" large="" die="" hole="" after="" wire="" may="" continue="" to="" appear="" deformed="" attenuation="" or="" pull="" off="" phenomenon="" process="" unstable="" k=""> 2.0 Description drawing stress σ1 smaller, pass drawing deformation amount is too small, drawing passes increased. The pull wire drawing diameter of less than 0.05mm ultra-fine wire, clothing die hard, in order to improve the stability of the drawing process, reduce the number of mold to pull off and wear, improve drawing productivity, safety factor K may be greater than 2.0.Plastic Pallet for sale

People have an affinity for wood, home decorating with wood. But wood also has its own shortcomings, easy to shrinkage cracking, water variable type, when wet easy to mold, fire, flammable if doors with plywood, wood fence panels priceswhich will pollute the indoor formaldehyde. Is there a "merit only wood, no wood defects", "is not a wood, wood is worth," the new material? Now with. This is the processing of wood flour and PVC plastic with wood-plastic composites (WPC).

In other countries, after ten years of research, development and industrial applications, WPC has become a new industry. WPC wood flour, agricultural straw powder plant fiber and plastic as the main raw material, Cheap Outdoor Fence Export New Zealandthe use of advanced processing technology, and products can be repeated recycling. From the organoleptic point of view, wood-plastic material has good wooden texture, moisture, color is good, thermal insulation corrosion,

mechanical properties than pure wood materials 10 times to become the ideal substitute for natural wood. Mainly waste plastics and branches pink tree branches, agricultural straw powder plant fiber as raw materials,pvc car mat pvc foot mat manufactured products are widely used in packaging, landscape, transportation, construction, travel and other interior areas. "Plastic wood, plastic and steel, saving resources and protecting the environment."
