Baoding in Hebei Mold Factory (Liangjing Tel: 15932263226 qq:? 414801412) manufactured shutters mold which is characterized by low cost, high security, but the weight of large, impact fatigue resistance is poor, prone to breakage, short life, poor image and open inconvenient. In the matter due to mold plastic fill and flow are exposed to greater stress and friction, requiring precision molds link shape and dimensional accuracy of stability, guarantee adequate use of mold life. Die wear resistance depends on steel and chemical factors heat punishment hardness, thereby increasing the hardness of the mold will help improve the wear resistance. Die difference what conditions the mold, in addition to being definitely pressure, but also suffer temperature. To do this requires the selection of the steel material fewer impurities, uniform fine structure, no fiber bias, there should not be pitting or orange peel-like defect during polishing. Development of mold is a new breakthrough, easy to use, fast, simple, improve your work efficiency. The mold with acid, alkali, moisture resistance, corrosion and other characteristics, the mold has a dedicated connection snaps, formwork and form removal is very easy. Bridge shutters mold, mold cement component bridges shutters, steel storage: After entering reinforcement shall specifications, numbered plus stacking skids, the lowest point from the ground not less than 20cm. Former steel banding, you should check whether there is corrosion phenomenon, after the rust and then transported to the banding site. Familiar with the drawings, according to the design specifications of reinforced inspection has been processed, the shape, the number is correct. Steel storage: After entering reinforcement shall specifications, numbered plus stacking skids, the lowest point from the ground not less than 20cm. Former steel banding, you should check whether there is corrosion phenomenon, after the rust and then transported to the banding site. Familiar with the drawings, according to the design specifications of reinforced inspection has been processed, the shape, the number is correct. Steel processing steel before processing should see if there are inspection laboratory approach proved and check for cracks appearance quality steel, heavy leather, porosity, oxide, iron rust, bend die and oil and so on. With hook and bent steel reinforcement should be considered by the elongation after bending, cutting length is determined based on the actual experience (which can also try bending measured decision) rebar bending and end of the hook should meet the design requirements. When the design No, you should meet the following requirements: All end tension Hot rolled steel shall be made semi-circular hook 180 ° bending diameter dm hook of not less than 2.5d, hook end should be left not less than 3d is a straight line segment. By the end of the pull-rolled ribbed steel bars should be used rectangular-shaped hook, line length should not be less than the straight side of the hook bend hook bent reinforcement should not be smaller than the diameter of a smooth curve bent, it should not be less than the radius of curvature of the bar diameter (round bar) or 12 times (ribbed steel) round steel stirrups made of light, it is not the end of the hook should be less than 90 °; there are special requirements for seismic and other structures should be 135 ° or 180 ° bend hook hook bend diameter should be greater than the force bar diameter, and should not be less than the length of the diameter of the stirrup hook straight section: general structure should not be less than the diameter of the stirrup times, there are structural seismic requirements of not less than the diameter of the stirrups The steel banding: on the tire tool steel banding were shutters steel skeleton tie.
