Production lamp shade is recommended for injection molding machine

    Today's production processes are moving lamp shade mold precision manufacturing, precision injection molding, processing high precision automated manufacturing process development. A set of high-precision molds for shade selection of the injection molding machine is very important. From the life of the mold, use of raw materials, injection repeatability considerations, the proposed high-precision two-plate injection molding machine for processing, power systems recommended Germany Rexroth variable displacement piston pump, with a high response servo injection valve, so the biggest advantage is the ability to quickly configure a steady supply of injection pressure and injection speed, improve injection repeatability, reduce non-performing rate of injection, while reducing energy consumption. Disadvantage is the high manufacturing costs, higher than the servo power system cost more than 40%.

    To create a high level of precision lamp shade need to configure the tube group (comprising screw assembly), lamp shade is made of resin is generally PMMA (acrylic) and PC, the two resins to screw design, manufacturing process requirements are very high, the slightest mistake will lead to a subsequent injection molding bad (black spots, yellow), feed tube with alloy material manufacture, plus alloy plated screw using branded treatment. The entire tube group in the manufacturing process must be careful not to have corners, screw surface smoothness, high cleanliness requirements; three small pieces (of the screw head group) in conjunction with the head of the screw should not be dead; points plastic head (screw head) the outer teeth and the inner teeth of the screw with the clearance requirements for zero error (with the gap to be tight), if there will be bad with methane gas resulting in yellow resin; and the head tube flange, nozzle touch position adaptation is better, can not have fault (dead), once the feeding tube group are dead it will lead to poor product (black spots).
